4.3.1 Fire Alarm Response
The control panel will, upon detection of an alarm condition, cause the following:

Turn on the system Alarm LED

Blink the Zone Alarm Red LED (½ second On, ½ second Off)

Turn the Notification Appliance Circuits on

Turn the piezo sounder on steady

Turn on alarm relay
4.3.2 Fire Alarm Restoral
The control panel returns to normal after all alarms have been cleared and a system reset key has been pressed
(pull stations have been reset, smoke detectors have reset and no smoke is present, waterflow has stopped). The
control panel will perform the following upon restoral of all active alarms:

Turn off the alarm LED

Turn off the Zone Alarm LED

Turn off the Notification Appliance Circuits

Turn off the piezo sounder

Turn off appropriate zone relay output

Turn off alarm relay
4.3.3 System Supervisory Condition Response
These Supervisory zones can be for supervisory in applications where a waterflow sensing device has been
employed and the wiring to the waterflow valve and/or a tamper switch is to be monitored. If the tamper switch
has been activated (normally open contacts close), a supervisory alarm condition will occur.
When a supervisory condition occurs, the control panel will cause the following:

Turn on the supervisory LED

Pulse system piezo sounders (½ second On, ½ second Off)

Turn on supervisory relay
4.3.4 System Supervisory Restoral Response
When the supervisory condition has been cleared and the reset key has been pressed, the control panel will
perform the following:

Turn off the supervisory LED

Shut off system piezo sounders

Turn off supervisory relay
4.3.5 Fault Condition Response
The control panel will perform the following upon detection of one or more fault conditions:

Turn on the trouble LED

Blink the Zone fault LED if fault condition is on the zone (½ second On, ½ second Off)

Activate fault relay

Sound system piezo sounders at a rate of 1½ second On, 1½ second Off
4.3.6 Fault Condition Restoral
The control panel performs the following upon restoral of all trouble conditions:

Shut off the fault LED

Shut off the zone fault LED(s)

Shut off the piezo sounder

Deactivate the fault relay
