Silencing and reactivating sounders
The control panel operates in day or night mode. If
the system is silenced during day mode, the silence
status remains until the system is unsilenced unless
new alarms or faults occur. If the system is silenced
during night mode, the silence status remains until
the night mode silence time expires. When you turn
on the system, it starts in day mode by default.
Reset
Reset stops alarm, delay-to-alarm, warning, and
fault conditions. Access to this command is limited
to authorized personnel using an installer or user
access code. The system reprocesses any alarm,
delay-to-alarm, warning or fault signal that is not
cleared by a reset. Command keys cannot be used
when a reset is running.

The system status is indicated by the following
items:
• Status LEDs
