Control Switches
TONE SILENCE
Acknowledge 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
sounder silences. A Second trouble will resound the piezo. The piezo
has three distinct sounds for alarm, trouble, and supervisory. Trouble
conditions are self restoring. Alarms latch and require RESET to clear.
ALARM SILENCE
Acknowledge for alarms and supervisories. The ALARM SILENCE
switch will silence the local piezo, change any flashing alarm LEDs to
steady, and turn off the notification appliance circuits (not the releasing
circuits). The “ALARM SILENCED” LED will illuminate. Alarm silence
is a latching function and requires a RESET to clear.
ALARM ACTIVATE
The ALARM ACTIVATE switch may be used to activate Notification
Appliance Circuits. ALARM ACTIVATE also activates the System Alarm
relay. ALARM ACTIVATE is a latching function. Pressing ALARM
SILENCE silences the notification appliance circuits and System Alarm
Relay and lights the Alarm Silenced LED. Pressing RESET returns the
system to normal.
SYSTEM RESET
The RESET switch breaks power to all initiating device circuits, 4-wire
smoke power and option boards and will clear any activated output
circuits. If any alarms or troubles still exist after reset, they will re-
activate the panel. Holding RESET down will perform a LAMP TEST
function and will activate the piezo sounder.
2.3
Zone Status LEDs
The alarm and/or trouble LED(s) will flash until the
event(s) has been acknowledged (TONE or ALARM
SILENCE), at which point the LED(s) will illumi-
nate steadily.
