in detector chamber, pull station was not reset, etc.) the panel remains in an alarm state
after resetting and the NACs and other outputs do not reactivate.
• Disabled devices and zones remain disabled after the panel is reset.
• Resetting the panel does not log off user level one or user level two access.
Silencing panel and annunciator buzzers
The panel buzzer sounds whenever an event message is received at the control panel.
Pressing the Ack/Panel Silence button:
• Silences the buzzer on the control panel and all remote annunciators.

• Silences the panel buzzer on all remote annunciators. If more than one event is queued,
the LCD displays event 001.
To silence the buzzer:
1. Determine what event caused the buzzer to sound by pressing Enter to view the event
details. This displays the loop number, device address, and a detailed description of the
event type
2. Press the Ack/Panel Silence button on the panel, or the Ack/Silence button on any remote

Silencing notification appliances
WARNING: Do not silence notification appliances until the building is fully evacuated and the
cause of the alarm has been determined.

until the reset inhibit timer expires. See “What is in-suite signal silence?” on page 39.
