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 condi-
tions are self restoring. Alarms and supervisories 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. The "ALARM
SILENCED" LED will illuminate. Alarm silence is a latching function and
requires a RESET to clear.
Note: If Silence Inhibit has been selected (SW1, DIP switch #4 set to "ON"),
the Alarm Silence will not function until 60 seconds after the initiation
of the alarm.
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 alarm or trouble still exists after reset, they will reactivate
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
illuminate steadily.
Note: If zone 4 is set for supervisory, the red alarm
LED is not used.
