1. General description of the SQUEALER alarm unit.

The Squealer is a modern, microprocessor-based device designed for continuous monitoring the status of pre-configured HILEVEL (overflow sensor), OILER (oil level sensor) and the SLUDO (sludge level sensor). Basic functions: a) simultaneous, independent monitoring of on-line 1 to 3 sensors(overflow, the oil and

sludge); b) control of siren status, sensors and alarm events (LED, buzzer); c) in the case of an alarm, the module converts the signal from the sensor / sensors of the

measurement zone on a visual signal (LEDs located on the housing), activates an acoustic signal (internal buzzer), activates one or three potential-free output;

d) ability to work on the additional battery (1,2Ah) ~ 3 h. e) after power-on the module is activating after 60 [s] delay aimed at stabilizing the

operation of sensors.

2. Control panel description

and distance between sensors the alarm unit.

5. OILER sensor characteristic

The OILER sensor is used for controlling of maximum thickness of oil, mineral liquid or organic liquid. The signal depends on the surrounding environment (conductivity phase). Direct connectionof the sensor to the alarming module enables continuous monitoring of liquid level. Sensor element, is placed on the upper joining part of the metal and non-metallic parts (black). The alarm occurs when the phase of the environment surrounding sensor changes: water oil, petroleum liquid or from water to air.

6. HILEVEL sensor characteristic

HILEVEL is a hanging sensor and is used to detect and alarming high level of liquid in the separator/settling tank. The sensor allows to distinguish liquid from the air, where the fluid can also be a liquid petroleum. Generating an alarm signal is formed by immersing the sensor in the liquid.

7. SLUDO sensor characteristic

The SLUDO sensor is used to detect sludge layer in the separator. During normal operation a sound wave or pulse is sent from one part of the sensor and captured by the second part. If the sensor is in the liquid, the wave is not bent - the siren is operating normally. Alarm situation occurs when an area of the signal enters the layer of sediment, which interferes with the free movement of the wave. Sensor SLUDGO tells us about exactly accumulated sediment layer and indicates the need to clean the separator. This device can minimize the need to control the level of sediment.

8. Installation of the sensors

During the installation of sensors in hazardous areas, must be applied the appropriate safetyregulations.


a) The level sensor of petroleum/organic oil substance

In order to determine the change of the levels in controlled separator, the sensor should be placedat the right depth/height. Sensor element, is placed on the upper part of the sensor in place ofconection(silver and black).The sensor cable should be wound around the mounting ear (NFIX-01)in such a way that the line is blocked, and the sensor does not change its position on the holderduring operation. Sensor cable with a standard length of 5m hang on the handle, which must beplaced directly under the hatch - the best in the inspection hole in the lid of the separator.

Placing a the sensor should be performed in the following manner:

1. Separator filled with water to the overflow level, equal to the level of outflow2. The sensor placed inside the separator, at a depth (measured from connection the upper

metal and non-metallicpart), equal to the allowable layer thickness - for measuring thethickness of the oil liquid is 100 mm

3. Attach the sensor cable to the mounting ear4. In the case of extension of the sensor cable, the connection should realised by use of

connection junction.

b) Overflow sensor

The sensor cable should be wound around the ear mounting (NFIX-01) in such a way that the linewas blocked, and the sensor does not change its position during operation of the separator /settler. Sensor cable with a standard length of 5m hang on the handle, which must be placeddirectly under the hatch - the best in the inspection hole in the cover of the separator.

Placing the sensor should be performed in the following manner:

1. On the sensor housing, measuring up from the hole fi 5 mm, draw a mark (trait) at adistance equal to the maximum permissible level of sewage in the tank (for coalescenceseparator standard 50 mm from the upper edges of the coalescing)

2. Get lower the sensor so that previously made marking was on the desired level,3. Attach the sensor cable to the mounting ear,4. In the case of extension of the sensor cable, the end of the cable needs to be mounted in

the COUPLER-01 for connecting the sensor with the siren.

c) The sludge level sensor

Installation height of the sensor depends on the volume of sedimentary part of the device. Theamount of deposited grease can not exceed 1/3 ÷ 1/2 of the height between the bottom of outletpipe and the bottom of the sludge chamber. When installing the sensor, please note that usuallysludge accumulates in the zone of measurement at different heights, which depends primarily onthe speed of the flowing sewage. Where the flow rate is the lowest it has accumulated the most,and vice versa, the thickness of the sediment will be the lowest where speed is greatest.Sensor cable must be wrapped around the mounting ear (NFIX-01) in such a way that the line is


blocked, and the sensor does not change its position on the holder during operation. Sensor cablewith a standard length of 5m hang on the handle. Handles should be placed directly under thehatch - the best in the inspection hole in the cover of the separator.

Placing the sensor should be performed in the following manner:

1. Get lower the sensor so that the sensing elements located below the device housing were atan altitude of between 1/3 and 1/2 the height between the bottom outlet pipe and thebottom of the sludge chamber.

2. Attach the sensor cable to the mounting ear,3. In the case of extension of the sensor cable, the end of the cable install in the COUPLER-01

connecting the sensor with the siren.


9. Sensors maintenanceSensors should be regularly checked and cleaned during routine cleaning of separator / settler.When the sensors are very dirty, they may generate false alarms or not to declare an alarm whennecessary.

11. The junction sleeve COUPLER-01 or junction COUPLER BOX

The sensors are with standard 5m cables equipped. Often, the length is insufficient to make theconnection between the sensor and alarm module, located eg. in the room of technicalsupervision. In such a situation it is necessary to extend the cable. For this purpose, should be useda additional cable, which should be connected with the sensor using the junction sleeve COUPLER-01. The junction sleeve should be placed in the separator in a way that will allow access from theground level, without entering the interior of the separator - you can either use the mountingbrackets for mounting the sensor (see figure below). This will facilitate the eventual removal of thesensors for the purpose of cleaning, repair or replacement.


When cleaning separator, pay special attention to not to damage the installed sensors. Before cleaningseparator / settler remove the sensors because they are susceptible to mechanical damage. The sensors

can be placed back in the separator / settler after the completion of all maintenance work.

Use of junction sleeve, junction box

The length of the connected cable between the sleeve and the passage through the wall of theseparator, allow to draw the junction module through the hatch seal and disconnect the wires onthe ground level.

Due to the fact that the interior of the separator is treated as an area at risk of explosion, shouldbe used the junction sleeve intrinsically safe, like COUPLER-01. Sleeve/box junction should beinstalled in a place accessible without disturbing the operation of the separator.

In the case of use the coupling COUPLER-01, derived connection cable must lead up to the room where the siren is installed. The cable should be placed in a protective tube, recessed in the ground at a depth of approx. 60-70 cm.


Lengths of extensions cables to the sensors:• 2x0,75mm2 - maximum 190m.• 2x1,0mm2 - maximum 250m.

Wiring: power supply, sensors and potential free outputs

The sensor cables to the siren can be extended using:

a) a single two-wire cable for each sensor. This is the recommended method. Typically, thesensor cable is connected to the extension cable using a coupling connecting certified forhazardous area.

b) the cable 4 or 6-wire (depending on the number of sensors) and a junction box located in aseparator from which the cables are conducted to each of the sensors.

Using a cable 2 x 1 mm2, the extension can be granted up to:- max. 500m for OILER or SLUDO sensor - max. 250m for HILEVEL sensor Using a cable 2 x 1.5 mm2, the extension can be granted up to:- max. 800m for OILER or SLUDO sensor- max. 400m for HILEVEL sensor

The connection cable should not be conducted in a common bundle of cables of other circuits that couldinterfere with signaling by inducing a fault signal in the sensor circuit

12. Wiring the emergency power supply, USB and security burglar sensor

When configuring sounder module with additional emergency power supply and / or protectionagainst Burglary (sensor alarm), a suitable cable must be carried out by two additional couplers. Ifthe anti-theft sensor is not connected, the circuit must be closed.

13. Emergency power supply

In case of power failure, it is not possible to initiate the sensor alarm signal. The system also doesnot inform about the event by sending an SMS. To prevent fading power supply, alarm systemSquealer can be further provided with emergency power NSOLAR-10 (optional). In the case of theuse of emergency power Squealer report it is sent text SMS in case of loss of voltage of 230 V. Ifthe main power supply is restored siren will send back information about the power returns. In thecase of extended power outages while the battery indicator operates in accordance with theconfiguration settings in a standard way for approximately 5 hours. If the battery level will preventfurther normal operation of the siren, the device is turned off, but the SMS will be sent to theindicated numbers with information about the system is turned off.

14. System Configuration

Inside the enclosure, on the main board, is available four-position "dipswitch." It is used toconfigure the siren after sensors connection. The switches have to be set according to the desiredconfiguration of the sensors.

DIP switch 1: activation / blocking of the overflow sensor"ON" - if the sensor is installed"OFF" - if the sensor is not installed

DIP switch 2: activation / blocking of the oil sensor"ON" - if the sensor is installed"OFF" - if the sensor is not installed

DIP switch 3: activation / blocking of the sediment sensor"ON" - if the sensor is installed"OFF" - if the sensor is not installed


Loss detection and return of power supply 230 is implemented with a delay of 5 minutes, which preventsthe sending of SMS messages during the short power interruptions

DIP switch 4: Selecting the delay time of alarm events for sensors"ON" - alarm delay time of 5 s"OFF" - alarm delay time 30 s

DIP switch 5: Selecting the overflow sensor Set the "ON" - if the sensor is installed SLU-103Set to "OFF" - if the sensor is installed NVF-104/34

DIP switch 6: Selecting the action of potential-free outputs"ON" - when the alarm from any sensor is to correspond to the operation of all potential-freeoutputs."OFF" - if the alarm from a specific sensor is to correspond to a specific output, ie. overflow sensor- REL1, oil sensor - REL2, sludge sensor - REL3.


In the standard operation it is recommended to use a time delay of 30 [s]
