Features List
Enclosure
Injection moulded, 3-part, ABS plastic, flame retardant enclosure.
Surface or Semi-flush mounting.
14 x 20mm Gland knockouts at the top.
Temperature-compensated
battery charging
Battery charging voltage is automatically adjusted between 28.25Vdc and
26.72Vdc over an ambient temperature range of
–5°C to +40°C.
Battery disconnect
Prevents permanent damage to the battery due to deep discharge by
automatically disconnecting it when the battery voltage falls below 21.6V.
Remote Control input providing
five controls:
1. Class Change
Operates all sounders for up to 5 seconds without giving any panel
indications.
2. Alert
Pulses all sounders and operates the fire buzzer.
3. Evacuate
Operates all sounders continuously and operates the fire buzzer.
4. Silence Alarms
Latches the Silence Alarms condition until a new alarm condition is
detected or until panel reset.
5. Reset
Returns the panel to the quiescent state after a fault or alarm
condition.
Configurable detection zones
DIL switch configuration provides the following capabilities:
Latching or non-latching Fire indication on zone 1.
Resistor or capacitor EOL monitoring
– applies to all zones. (Not
functional on Twin-Wire panels)
Zone Short Circuit gives fault or fire alarm (for backwards
compatibility)
– applies to all zones.
Factory configuration:
Latching zone 1 Fire indication
Capacitor EOL (not for twin-wire)
Zone Short circuit gives fault.
Selectable Zonal or General
Alarm Sounder operation
Selectable via DIL switches on the motherboard.
When set to Zonal, the sounders operate as follows:
Twin-wire panels ( 1 to 8 zone):
All 2-wire sounders operate zonally, normal sounder circuits operate
as general alarms
Standard panels, 1 to 4 zone panels:
Sounder circuits 1 to 4 operate individually for a fire condition on the
respective zone.
Standard panels, 8-zone panel:
Sounder circuits 1 to 4 operate as general alarms.
Alert Sounder operation
DIL switch selectable on the motherboard.
When the Alert Mode DIL switch is set to the ON position, sounders pulse
for automatic detector alarms and are continuous for Manual Call Point
alarms. NOT COMPATIBLE WITH RESISTOR EOL.
Zonally configurable co-incidence
(dependency) for Automatic Fire
Detectors
Programmable facility which allows any zone to be configured for co-
incidence (dependency) detection. Requires two occurrences of detector
activation within 30 minutes before an alarm is raised. Manual call points
are not affected.
