Indicators, Controls and Operations
9.2.2 SIGNAL SILENCE Button
Press the SIGNAL SILENCE button when the panel is in alarm to deactivate any silenceable
indicating circuits. Non-silenceable circuits are unaffected. Signals resound if there is a
subsequent alarm. Pressing SIGNAL SILENCE again resounds all silenceable signals. This
button does not function when the signal silence inhibit timer is running (see "6 Signal Silence
Inhibit timer" on page 56). It also does not function if the indicating circuits are active as the
result of a fire drill.
9.2.3 FIRE DRILL Button
The FIRE DRILL button activates all non-disconnected (un-bypassed) indicating circuits, but
does not transmit any alarms via the city tie, Common Alarm Relay or Auxiliary Alarm Relay.
The fire drill activates the signals in the evacuation code programmed. For example, if the
evacuation code is set to Temporal Code, the signals will be pulsed on for 0.5 seconds, off for
0.5 seconds in rounds of 3 and then pause for 1.5 seconds and repeat.
The fire drill is canceled by pressing the button again, or if the panel goes into a real alarm.
9.2.4 LAMP TEST Button
Press the LAMP TEST button to make the front panel indicators steadily illuminate (except for
CPU FAIL) and to turn the buzzer on steady. If the lamp test is active for more than 10
seconds, the Common Trouble is activated.
Press and hold the LAMP TEST for 3 seconds to show the information about the system and
the firmware version as shown below.

The first line shows the number of zones and panel type and the second line shows the
software version number.
9.2.5 BUZZER SILENCE Button
Press the BUZZER SILENCE button while the buzzer is sounding to silence the buzzer. The
buzzer resounds if there is a subsequent event. Pressing the button when the buzzer is not
sounding has no effect.
9.3 Common Relays
9.3.1 Common Alarm Relay
The Common Alarm Relay (labeled ALARM RELAY on the circuit board) activates when a
general alarm sequence is activated. Since all alarm conditions are latched until system reset,
the relay remains on until the alarm is cleared and the system is reset. The Common Alarm
Relay can be disconnected by “Aux Disconnect” (see "Aux. Disc. (Command Menu)" on
page 75) if programmed to do so (see "Table 7 Feature Config menu" on page 56.
