silence" light. Display of identity of the alarm zone or device is retained.

2. Subsequent alarm signals, from other devices or zones, shall reactivate notification appliances, until

silencing switch is operated again.

3. When alarm-initiating devices return to normal and system reset switch is operated, notification

appliances operate again until alarm silence switch is reset.

Remote Detector Sensitivity Adjustment: Manipulation of controls at the MFACP/FACP shall cause theselection of specific addressable smoke detectors for adjustment, display of their current status and sensitivity

settings, and control of changes in those settings. Same controls can be used to program repetitive,

scheduled, automated changes in sensitivity of specific detectors. Sensitivity adjustments and sensitivity-

adjustment schedule changes shall be recorded in system memory and printed out by the system printer.

Removal of an alarm-initiating device or a notification appliance initiates the following:

1. A "trouble" signal indication at the Control Panel and the annunciator for the device or zone involved.


Printout of Events: On receipt of the signal, print alarm, supervisory, and trouble events. Identify zone, device

and function. Include type of signal (alarm, supervisory, or trouble), and date and time of occurrence.Differentiate alarm signals from all other printed indications. Also print system-reset event, including the same

information for device, location, date, and time. Commands initiate the printout of a list of existing alarm,

supervisory, and trouble conditions in the system and a historical log of events.
