Silencing the operator alert signal
The control unit sounds the operator alert signal when an event message is posted into one of the event message
queues. Pressing the Panel Silence button silences the operator alert signal.
Notes
• Pressing the Panel Silence button may also silence the operator alert signal on remote annunciators, if the
system is configured to do so.
• For proprietary systems, the Panel Silence button is not operational. The operator alert signal only silences
after each event has been individually acknowledged (see “Acknowledging events” on page 19).
• The control unit panel silence function can be programmed for a fire privilege level. The default setting is no
PIN required.
To silence the panel operator alert signal:
1. Press the Panel Silence operator control button.
2. If prompted, enter the fire privilege PIN using the interactive keypad.
Silencing alarm signals
WARNING: Death or serious injury. The protected premises may be occupied. Do not silence alarm signals or
reset the control unit unless you are authorized to do so and only after all occupants have been evacuated.
Pressing the Alarm Silence operator control button silences all audible alarm signals and, if configured, all visual
alarm signals. Pressing the button a second time turns back on the signals.
Pressing the Alarm Silence operator control button does not silence alarm signals when:
• A waterflow alarm switch is active and the system is configured to prevent silencing alarm signals when a
waterflow alarm switch is active
• The system is configured to delay the silencing of alarm signals, in which case the Alarm Silence button may
not be operational for up to five minutes following the first alarm event
Silenced outputs automatically re-sound when:
• The Alarm Silence button is pressed a second time
• Another alarm input activates
• Another alarm input in the same zone activates, unless the system is configured to prevent alarm signals from
re-sounding
Note: The alarm silence function can be programmed for a fire privilege level PIN. The default setting is no PIN
required.
To silence alarm signals:
1. Press the Alarm Silence operator control button.
2. If prompted, enter the fire privilege PIN using the interactive keypad.
