automatic fire alarm system–typically made up of smoketectors, heat detectors, manual pull stations, audible warn- devices, and a fire alarm control with remote notification

pability–can provide early warning of a developing fire.ch a system, however, does not assure protection againstperty damage or loss of life resulting from a fire.

e Manufacturer recommends that smoke and/or heat detec-s be located throughout a protected premise following theommendations of the current edition of the National Fire

otection Association Standard 72 (NFPA 72),nufacturer's recommendations, State and local codes, and recommendations contained in the Guide for Proper UseSystem Smoke Detectors, which is made available at noarge to all installing dealers. A study by the Federal Emer-ncy Management Agency (an agency of the United Statesvernment) indicated that smoke detectors may not go off in many as 35% of all fires. While fire alarm systems are de-ned to provide early warning against fire, they do not guar-tee warning or protection against fire. A fire alarm systemy not provide timely or adequate warning, or simply may notction, for a variety of reasons:

oke detectors may not sense fire where smoke cannotch the detectors such as in chimneys, in or behind walls, onfs, or on the other side of closed doors. Smoke detectorso may not sense a fire on another level or floor of a build-. A second-floor detector, for example, may not sense at-floor or basement fire.

rticles of combustion or "smoke" from a developing firey not reach the sensing chambers of smoke detectors be-

use:

Barriers such as closed or partially closed doors, walls, orchimneys may inhibit particle or smoke flow.

Smoke particles may become "cold," stratify, and not reachthe ceiling or upper walls where detectors are located.

Smoke particles may be blown away from detectors by airoutlets.

Smoke detectors may be drawn into air returns beforereaching the detector.

e amount of "smoke" present may be insufficient to alarmoke detectors. Smoke detectors are designed to alarm atrious levels of smoke density. If such density levels are notated by a developing fire at the location of detectors, the

tectors will not go into alarm.

oke detectors, even when working properly, have sensingitations. Detectors that have photoelectronic sensingambers tend to detect smoldering fires better than flamings, which have little visible smoke. Detectors that have ion-g-type sensing chambers tend to detect fast-flaming fires

tter than smoldering fires. Because fires develop in differ-t ways and are often unpredictable in their growth, neithere of detector is necessarily best and a given type of detec- may not provide adequate warning of a fire.

oke detectors cannot be expected to provide adequaterning of fires caused by arson, children playing withtches (especially in bedrooms), smoking in bed, and violent

plosions (caused by escaping gas, improper storage ofmmable materials, etc.).

Heat detectors do not sense particles of combustion andalarm only when heat on their sensors increases at a prede-termined rate or reaches a predetermined level. Rate-of-riseheat detectors may be subject to reduced sensitivity over timFor this reason, the rate-of-rise feature of each detectorshould be tested at least once per year by a qualified fire protection specialist. Heat detectors are designed to protectproperty, not life.

IMPORTANT! Smoke detectors must be installed in thesame room as the control panel and in rooms used by the sytem for the connection of alarm transmission wiring, communcations, signaling, and/or power. If detectors are not so lo-cated, a developing fire may damage the alarm system, crip-pling its ability to report a fire.

Audible warning devices such as bells may not alert peopleif these devices are located on the other side of closed orpartly open doors or are located on another floor of a buildingAny warning device may fail to alert people with a disability othose who have recently consumed drugs, alcohol or medication. Please note that:

• Strobes can, under certain circumstances, cause seizuresin people with conditions such as epilepsy.

• Studies have shown that certain people, even when theyhear a fire alarm signal, do not respond or comprehend themeaning of the signal. It is the property owner's responsibity to conduct fire drills and other training exercise to makepeople aware of fire alarm signals and instruct them on theproper reaction to alarm signals.

• In rare instances, the sounding of a warning device cancause temporary or permanent hearing loss.

A fire alarm system will not operate without any electricalpower. If AC power fails, the system will operate from standbbatteries only for a specified time and only if the batterieshave been properly maintained and replaced regularly.

Equipment used in the system may not be technically com-patible with the control. It is essential to use only equipmentlisted for service with your control panel.

Telephone lines needed to transmit alarm signals from apremise to a central monitoring station may be out of serviceor temporarily disabled. For added protection against tele-phone line failure, backup radio transmission systems are recommended.

The most common cause of fire alarm malfunction is inade-quate maintenance. To keep the entire fire alarm system inexcellent working order, ongoing maintenance is required pethe manufacturer's recommendations, and UL and NFPA standards. At a minimum, the requirements of Chapter 7 of NFPA72 shall be followed. Environments with large amounts ofdust, dirt or high air velocity require more frequent mainte-nance. A maintenance agreement should be arrangedthrough the local manufacturer's representative. Maintenancshould be scheduled monthly or as required by National and/or local fire codes and should be performed by authorized prfessional fire alarm installers only. Adequate written recordsof all inspections should be kept.

While a fire alarm system may lower insurancerates, it is not a substitute for fire insurance!ire Alarm System Limitations

Therefore, it is recommended that this systemd all peripherals be installed in an environment with a nomi-l room temperature of 15-27° C/60-80° F.

rify that wire sizes are adequate for all initiating andicating device loops. Most devices cannot tolerate moren a 10% I.R. drop from the specified device voltage.

Like all solid state electronic devices, this system mayoperate erratically or can be damaged when subjected to lighning-induced transients. Although no system is completelyimmune from lightning transients and interferences, propergrounding will reduce susceptibility. Overhead or outsideaerial wiring is not recommended, due to an increased sus-ceptibility to nearby lightning strikes. Consult with the Techncal Services Department if any problems are anticipated orencountered.

Disconnect AC power and batteries prior to removing or inserting circuit boards. Failure to do so can damage circuits.

Remove all electronic assemblies prior to any drilling, filingreaming, or punching of the enclosure. When possible, makall cable entries from the sides or rear. Before making modifcations, verify that they will not interfere with battery, trans-former, and printed circuit board location.

Do not tighten screw terminals more than 9 in-lbs.Over-tightening may damage threads, resulting in reducedterminal contact pressure and difficulty with screw terminalremoval.

Though designed to last many years, system componentscan fail at any time. This system contains static-sensitivecomponents. Always ground yourself with a proper wrist strabefore handling any circuits so that static charges are re-moved from the body. Use static-suppressive packagingto protect electronic assemblies removed from the unit.

Follow the instructions in the installation, operating, andprogramming manuals. These instructions must be followedto avoid damage to the control panel and associatedequipment. FACP operation and reliability depend uponproper installation by authorized personnel.

Introduction

ScopeThis document covers the installation and wiring of various Signaling Line Circuit (SLC) devices, when used with the following ADT Fire Alarm Control Panels:

This document also provides basic information that applies to ADT SLC loops in general, such as the branch resistance measurements.

Additional information about each control panel and the modules and detectors referenced in this document can be found in the respective installation manual as listed in Table 1, “Reference Documentation,” on page 11.

OverviewCommunication between the control panel and intelligent and addressable initiating, monitor, and control devices takes place through a Signaling Line Circuit (SLC), which can be wired to meet the requirements of NFPA Style 4, Style 6, or Style 7.

Devices

Isolator Modules

Isolator Modules permit a zone of detectors and modules to be fault isolated from the remainder of the SLC loop, allowing critical components to function in the event of a circuit fault. Isolator modules are required to meet the requirements of an NFPA Style 7 circuit.

Monitor Modules

These addressable modules allow the control panel to monitor entire circuits of conventional alarm initiating devices, such as manual pull stations, smoke detectors, heat detectors, waterflow and supervisory devices.

Control Modules

Through these addressable modules, the control panel can selectively activate Notification Appliance Circuits (NAC).

Relay Modules

This addressable module provides the control panel with a dry-contact output for activating a variety of auxiliary devices.

Introduction SLC Capacity

SLC CapacityThe individual control panel determines the capacity of devices that can be incorporated into an SLC. See the specific installation manual for this information.

SLC PerformanceSLC performance depends on the type of circuit: Style 4, Style 6, or Style 7.

Note: SLC operation meeting Style 7 requirements isolates each device on the SLC from faults that may occur on the SLC.

Wiring style requirements are determined by national and local codes. Consult with the Authority Having Jurisdiction before wiring the SLC.

The table below lists the trouble conditions that result when a fault exists on an SLC.

Table 2 SLC Performance

LED OperationThe table below lists the LED operation on the various devices of an SLC.

Surge SuppressionAt least one secondary surge protector must be used with each SLC wiring pair whenever SLC wiring runs outside the building. For detailed information refer to "Appendix B: Surge Suppression" on page 47.

Wiring Requirements

OverviewIt is recommended that all SLC wiring be twisted shielded pair to minimize the effects of electrical interference except when using the LIB-200A or LIB-400 where non-shielded wire is recommended.

Wire size should be no smaller than 18 AWG (1.0 mm2) and no larger than 12 AWG (3.25 mm2) wire.

Two-Wire SLC - Style 4 (Class B)

Measuring Loop Resistance

T-tapping of the SLC wiring is permitted for 2-wire Style 4 configurations. The total DC resistance from the control panel to each branch end cannot exceed 40 ohms. Measure DC resistance as detailed and shown below:

1. With power removed, short the termination point of one branch at a time and measure the DC resistance from the beginning of the SLC to the end of that particular branch.

2. Repeat this procedure for all remaining branches in the SLC.

Figure 1 Measuring DC Resistance of a Two-Wire SLC

Measuring Total Wire Length

The total wire length of all combined branches of one SLC cannot exceed the limits set forth in each system’s instruction manual. Determine the total length in each SLC by summing the wire lengths of all branches of one SLC.

In the following figure, the total length of the SLC is determined by adding the lengths of Branch A + Branch B + Branch C.

Shielded Wire Termination for Reduction of Radiated Emissions

OverviewThe drawings below show four methods of proper termination of the shield, depending on the type of conduit used:

• No-conduit• Full-conduit• Partial-conduit• Floating Shield

Shielding of the SLC is not recommended in all applications. Refer to the “Floating Shield” section for specific instances where it is not recommended.

Use of good wiring practice consistent with local electrical codes is expected.

No-ConduitScrape the paint on the cabinet to bare metal to provide a good electrical connection. Connect the shield drain wire to the connector screw as shown below. Do not allow the shield drain wire to enter the system cabinet.

Figure 5 Shield Termination – No Conduit

Full-ConduitConnect the metal conduit to the cabinet by using the proper connector. Feed the shielded wire through the conduit, into the control box. The shield drain wire must be connected to the “reference” or “shield” terminal on the SLC terminal block, or connected to the negative side of the loop if there is no “reference” or “shield” terminal on the SLC terminal block. Do not let the shield drain wire or the shield foil touch the system cabinet or be connected to earth ground at any point.

Figure 6 Shield Termination – Full Conduit

Note: For Style 6 or Style 7 SLC wiring, connect one end of the shield to the reference/negative side of the respective channel.

Shielded Wire Termination for Reduction of Radiated Emissions Partial-Conduit

Partial-ConduitIf the length of conduit from the control panel cabinet exceeds 20 feet (6.1 meters), terminate the shield as shown. If using a metal box, you must use a metal conduit.

Connect the shielded wire to the junction box by using a proper connector. Scrape the paint on the cabinet to bare metal to provide a good electrical connection. Connect the metal conduit between the junction box and the cabinet by using the proper connectors.

Feed the twisted-pair wire into the junction box, through the conduit, into the cabinet box. Within the junction box, connect the appropriate wires together using wire nuts. Connect the shield drain wire to the junction box, at the end of the conduit run, as shown below.

Do not allow the shield drain wire to enter the system cabinet or the conduit.

Figure 7 Shield Termination – Partial Conduit

Floating ShieldWhere shielding of the SLC is not recommended (when using the LIB-200A or LIB-400):

1. The SLC is less than 3000 feet (914.4 meters).

2. The shield is divided into floating segments of less than 1000 feet (304.8 meters).

To divide the shield wire into floating segments, cut shield even with jacket and tape as shown:

SLC Circuits with Isolators

OverviewThere are two isolator devices used to protect critical elements of the SLC from faults on other SLC branches or segments:

• Fault Isolator Module M500X• Isolator Detector Bases

A Fault Isolator Module on both sides of a device, or the combination of an Isolator Base and Isolator Module are required to comply with NFPA Style 7 requirements.

If relay or sounder bases are not used a maximum of 25 addressable devices can be connected between Isolator Modules and/or Bases. When relay or sounder bases are used, the maximum number of addressable devices that can be connected between Isolators is reduced to seven. Due to the heavy current draw of the 3251 Multi-Sensor Detector the maximum number of these detectors that can be installed between isolator modules is reduced to two (2). Isolator modules will not function properly when these limits are exceeded.

When more than 100 Isolator Modules and/or Bases are connected to an SLC loop, the address capacity of the loop is reduced by two (2) addresses for every isolator device in excess of 100.

Fault Isolator Module - M500XThe module continuously monitors the circuit connected to terminals 3(–) and 4(+). Upon powerup, an integral relay is latched on. The module periodically pulses the coil of this relay. A short circuit on the SLC resets the relay. The module detects the short and disconnects the faulted SLC branch or segment by opening the positive side of the SLC (terminal 4). This isolates the faulty branch from the remainder of the loop preventing a communication problem with all other addressable devices on the remaining branches (labeled “Continuation of the SLC” in the figure below). During a fault condition, the control panel registers a trouble condition for each addressable device which is isolated on the SLC segment or branch. Once the fault is removed, the module automatically reapplies power to the SLC branch or segment.

SLC Circuits with Isolators Isolator Detector Bases

Isolator Detector BasesIsolator detector bases prevent an entire communications loop from being disabled when a short circuit occurs. This is accomplished by isolating that part of the loop containing the short from the remainder of the circuit. These bases also automatically restore the entire loop when the cause of the short circuit is corrected.

B224BI and B524BI are intelligent isolator bases for smoke detectors.

How an Isolator Base Works

If a fault occurs at point “Z”, devices A, B, & C will cease to function and display a trouble warning at the control panel. Devices D, E, & F will remain normal. Isolator bases 1 through 4 will remain normal as isolator base ‘1’ will be served by ‘SLC Out’ and isolator bases ‘4, 3, & 2’ will be served by ‘SLC Return’.

If a fault occurs at point “X”, devices A through F will remain normal. Only the device in isolator base 2 ceases to function..

NFPA Style 6 SLC Using M500X ModulesA variation of Style 6 operation using isolator modules to protect a section of the SLC. By flanking each group of devices with an M500X fault isolator module each group is protected from faults that may occur in the other groups. For example, a fault in Section B will not affect Sections A & C. The isolator modules on either side of Section B will open the loop. Section A will still operate from power on the SLC Out side and Section C will operate from the SLC Return side.

• A combination of isolator modules and isolator bases may be used.• T-tapping is NOT allowed within the Style 6 configuration.• M500X modules shall be within 20 feet (6.1 meters) of device and use metal conduit.

• T-tapping is NOT allowed for Style 7 configuration.• When a non-isolator base or pull station is used, install M500X modules on both sides of

devices.• When an isolator base is used in conjunction with an isolator module, install isolator module

after the base.• Connections between isolator bases and the device they isolate must be in conduit, within 20

Appendix A: Power Considerations

Supplying Power to 24 VDC Detectors

Resistance and Size

To determine the minimum resistance that can be tolerated in supplying power to 24 VDC 4-wire detectors, use the calculation below. Use this resistance to select the proper gauge wire for the power run from the manufacturers specifications for the desired wire.

Where:

Rmax = maximum resistance of the 24 VDC wiresVms = minimum supply voltage (see Table 3 below)Vom = minimum operating voltage of the detector or end-of-line relay, whichever is greater, in voltsN = total number of detectors on the 24 VDC supply circuitIs = detector current in standbyNa = number of detectors on the 24 VDC power circuit which must function at the same time in alarmIa = detector current in alarmIr = end-of-line relay current

The minimum supply voltages produced by ADT power supplies are listed below:

Appendix A: Power Considerations Supervising 24 VDC Power

Supervising 24 VDC PowerPower used to supply 24 VDC detectors, notification appliances (using the M300CADT) and two wire detectors (using the M302MADT) can be supervised with a power supervision relay. This relay, energized by the 24 VDC power itself, is installed at the end of each respective power run and wired inline with the supervised circuit of any intelligent module.

When power is removed from the relay, the normally closed contacts open the supervised circuit, generating a trouble condition. Therefore, the relay needs to be installed at the end of the supervised circuit, so as to not disrupt the operating capability of all the devices on that circuit. The relay can be installed inline with any leg (+ or –) of the supervised NAC or IDC circuit, either a two or a four-wire style.

The drawing below illustrates this concept.

Supervising 24 VDC Power to Notification Appliances Appendix A: Power Considerations

Supervising 24 VDC Power to Notification AppliancesAn alternate method of supervising 24 VDC power fed to the Notification Appliance Circuit of the M300CADT module eliminates the need for a power supervision relay. This method uses a Notification Appliance Circuit from the control panel or power supply to supply power to the M300CADT modules. The control panel supervises this circuit, which can be either a Style Y or Style Z.

Style Y NAC Power Wiring

Program the Main Power Supply NAC for general alarm. (Refer to the programming manual or programming section of your FACP documentation for instructions.) Note that if the NAC is a coded output, the M300CADT module will be coded as well.

Note: Refer to the Device Compatibility Document for compatible notification appliances.

• The circuit is supervised and power-limited.• In this circuit, an external ELR is required at end of the NAC circuit. • Refer to the respective control panel installation manual for NAC terminal block connection

information and ELR value.

Connect the NAC power as follows:.
