Indicators, Controls and Operations
• Stops and resets all Timers
• Processes inputs as new events
• Does not affect Aux Disconnect
8.4.2 Signal Silence Button
Activation of the Signal Silence button when the panel is in alarm turns on the Signal Silence
indicator and deactivates any Silenceable Indicating Circuits. Non-Silenceable Circuits are
unaffected. Signals will re-sound upon any subsequent alarm. Subsequent operation of signal
silence resounds all Silenceable signals. This button does not function during any configured
Signal Silence Inhibit Timer period.
8.4.3 Auxiliary Disconnect Button
Activating the Auxiliary Disconnect button activates the Auxiliary Disconnect function. The
Auxiliary Alarm Relay is always disconnected with this button. The Common Alarm Relay, the
Common Supervisory relay and all correlated alarm relays may be disconnected as selected
through configuration. Activating the Auxiliary Disconnect button also causes the Common
Trouble LED to illuminate steady, the common trouble relay to send a trouble message and
the trouble buzzer to flash at the trouble flash rate. Pressing the Auxiliary Disconnect button
again de-activates this function and the system will go back to normal.
8.4.4 Lamp Test Button
Activation of the Lamp Test button causes all front panel Indicators to steadily illuminate and
turns the buzzer ON steady. If Lamp Test is active for more than 10 seconds, Common
Trouble is activated.
8.4.5 ALM/SUP/TBL/BLDG AUDIBLE SIL Button (Buzzer Silence)
Activation of the ALM/SUP/TBL/BLDG AUDIBLE SIL button while the buzzer is sounding
silences the buzzer. The buzzer will resound if there is a subsequent event. Pressing the
button when the buzzer is not sounding has no effect.
8.5 Circuit (zone) disconnect buttons
Circuit (Zone) Disconnect pushbuttons are provided for all initiating indicating, and releasing
circuits on the Fire Alarm Control Panel. These pushbuttons are located beside their
respective indicating LED.
Pressing a Circuit Disconnect pushbutton bypasses the associated circuit and turns on its
Trouble Indicator, activating Common Trouble. Pressing a releasing circuit disconnect
pushbutton bypasses the associated releasing circuit and turns on its LED, activating common
supervisory. While a Circuit is disconnected, all changes in status (alarms and troubles) on
that circuit are ignored. The panel does not activate disconnected indicating circuits. Circuit
Disconnect pushbuttons are toggle switches; therefore, pressing an activated switch a second
time will un-bypass (reconnect) the circuit.
Disconnecting an active Latching Initiating Circuit (including Alarms, Water flow Alarm,
Sprinkler Alarm, General Alarm, and Latching Supervisory) does not affect its status until the
panel is reset. Disconnecting an active Non-Latching Initiating Circuit (including Non-Latching
Supervisory and Trouble-Only) causes them to behave as if the alarm situation has
disappeared. Disconnecting an active indicating circuit immediately deactivates the circuit.
