Fire Signal Output
Fully fault monitored output, providing 28VDC (nominal) at up to 250mA
when active.
Fire Relay Output
Non- monitored Relay output, providing one set of volt-free change-over
contacts.
Fault Relay Output
Non- monitored Relay output, providing one set of volt-free change-over
contacts, with fail-safe operation (fault signalled if total power failure)
Short Circuit Fire Option
A DIL switch selectable option on the motherboard to allow a short circuit
on the zones to be indicated as an alarm. For compatibility with older
detectors which do not have current limiting circuits.
NOTE: Automatic fire Detector activation will be detected by the panel as
a Manual Call Point alarm.
Auxiliary 24VDC 250mA power
supply output
Protected by a fast acting electronic fuse. Operation of the fuse is
indicated on the display. Operation of the Reset button on the panel
display resets the electronic fuse.
DIL switch configurable to switch off for 10 seconds during panel reset.
Open collector outputs
Three outputs capable of sinking 50mA each:
 Buzzer Active.
 Disablement Active.
 Evacuate Active.
Earth Fault monitoring
Can be disabled by removing a link on the control board.
Zone/Output disablement feature
The following circuits can be independently disabled/enabled:
 Each Zone
 Fire Signal Output
 All Sounders
Buzzer disablement feature
DIL switch selectable option to allow the buzzer and Buzzer Active output
to be prevented from operating.
Intended for use during commissioning and maintenance only.
One Man Zone Test
Each zone can be independently set to the One Man test condition.
Sounders will operate momentarily as per configuration of zonal alarms &
alert mode.
NOTE: Zone Dependency (co-incidence) is not applied during one-man-
test on a test zone.
One Man Sounder Test
Operates the general sounders (and twin-wire sounders if twin-wire
panel) intermittently.
Automatic fire detector and
manual call point fire event
discrimination
Each zone is capable of recognising whether a fire condition has been
caused by an automatic fire detector or a manual call point (unless the
panel is configured to EOL resistor monitoring on the zones). This is used
in conjunction with the dependency (co-incidence) feature and Alert alarm
mode.
Alarm Counter
The panel keeps a record of the number times it enters the alarm
condition. This count can be displayed on the display LEDs as a binary
value, up to a maximum value of 999 (1111101001). The counter can be
reset via a button on the motherboard which can only be accessed by
removing the front cover.
Repeater panels
Support for up to 3 repeater panels via two-wire RS485 serial
communication. [Repeaters are not available for the 1 & 2 zone panels].
