Tone Silence - Pressing this switch acknowledges alarms, troubles and supervisories. The panel has
alarm and trouble resound with LED flash of new conditions. The flashing trouble LED(s) illuminate
steadily on TONE SILENCE and the piezo turns off. A second trouble will resound the piezo. Trouble
conditions are self-restoring. Alarms latch and require pressing SYSTEM RESET to clear. Unless the unit
is set for non-latching supervisory service, supervisories latch and require pressing SYSTEM RESET to
clear. The piezo has three tones for different conditions (see "Piezo" on page 33).

Alarm Silence - Pressing this switch acknowledges for alarms and supervisories. This switch will
silence the local piezo, change any flashing alarm LEDs to steady, and turn off the notification circuits (not
the Releasing Circuits). The “Alarm Silenced” LED will illuminate. Alarm silence is a latching function
and requires pressing SYSTEM RESET to clear.

Alarm Activate - This switch may be used to activate Notification Appliance Circuits (NACs). It also
activates the System Alarm Relay. This is a latching function. Pressing ALARM SILENCE silences the
NACs and System Alarm Relay, and lights the Alarm Silenced LED. Pressing SYSTEM RESET returns
the system to normal.

NACs and System Alarm Relay, and lights the Alarm Silenced LED. Pressing SYSTEM RESET returns
the system to normal.
System Reset - This switch breaks power to all initiating circuits, four-wire smoke detector power and
optional boards and will clear any activated output circuits. If any alarm or trouble still exists after reset,
they will reactivate the panel. Holding SYSTEM RESET down will perform a LAMP TEST function and
will activate the piezo sounder.
