If a Coded Input Device (typically a pull station) activates, the ALARM SILENCE key may
be ignored until this function has completed coding. Notification appliances (horns) cannot be
silenced when a coded station is in alarm, but will silence upon coding completion.
If the Alarm Silence Inhibit Option - which is a timer that inhibits the operation of the
ALARM SILENCE function - is enabled, pressing the ALARM SILENCE key is ignored until
the timer expires. The message "ALARM SILENCE INHIBITED" displays for a short time to
indicate the action was not taken. The message "ALARM SILENCE NO LONGER
INHIBITED" displays when the timer expires.
If Waterflow Sprinkler Devices are activated, notification appliances may or may not be

sound to indicate water flow.
