System Reset Switch
The System Reset momentary switch resets the fi re alarm control panel and all circuits:
Resets all latching trouble conditions • Resets all initiating circuits •
Resets four-wire smoke supply • Turns off all NAC circuits •
Turns off Signal Silence • Turns off Fire Drill •
Stops and resets all timers • Processes inputs as new events •
Aux Disconnect is not affected •
Signal Silence Switch
Activating the Signal Silence momentary switch when the panel is in alarm turns on the signal silence indicator and deactivates
any silenceable NAC circuits. Non-silenceable circuits are unaffected. Signals will re-sound upon any subsequent alarm. This
switch does not function during any confi gured Signal Silence Inhibit timer period. It also does not function if the NAC circuits
are active as the result of a fi re drill.
Fire Drill Switch
The Fire Drill momentary switch activates all non-disconnected NAC circuits, but does not transmit any alarms via the DACT,
city tie, or common alarm relay, nor are any ARM-4 or ARM-8 relays activated. The fi re drill is cancelled by activating the
switch again, or if the panel goes into a real alarm.
Auxiliary Disconnect Switch
Activating the Auxiliary Disconnect momentary switch activates the auxiliary disconnect function. Activating the switch again
de-activates the function. When auxiliary disconnect is active, common alarm and common supervisory relays, and any ARM-4 /
ARM-8 relays are not activated. The trouble relay is activated. If installed, DACT or polarity reversal and city tie modules are
also inactive, causing a trouble condition.
Lamp Test Switch
Activation of the Lamp Test momentary switch turns all front panel Indicators and the buzzer on.
Buzzer Silence Switch
Activation of the Buzzer Silence momentary switch while the Buzzer is sounding silences the Buzzer. The Buzzer will resound if
there is a subsequent event. Switch activation will also silence the buzzer on all attached annunciators.
Circuit Disconnect Switches
Activation of these non-momentary switches disconnects the respective Initiating Circuit, and causes a Circuit Trouble for that
Initiating Circuit while active. If the disconnect switch is turned off (to its normal position) while there is an Alarm condition in
that circuit, the respective circuit Status LED will fl ash at a rate of 120 fl ashes per minute to indicate a Pending Alarm, for 5
seconds. If the disconnect switch is not turned back on, an Alarm will be processed normally. To enable Circuit Disconnect
feature, confi guration DIP switch 9 #3 must be set to “ON”.
