Auxiliary Power: Aux 24V (Nominal) O/P +, Aux 24V (Nominal) O/P -
250mA of auxiliary, nominal 24V DC power (between 21 & 32 volts) is available here. It is
recommended that additional Power Supply Units be installed to provide power for additional
loads.
Remote Alarm Output: Remote Alarm O/P +/-
The remote alarm output may be used to connect a standard 24V DC conventional relay. This is
monitored for short circuit and open circuit with a 4K7 ohm ‘End Of Line’ resistor and is rated at
24V DC 250mA. The relay operates when the control panels enters the fire state and deactivates
when the system is reset. Any relays must be dioded. See the section on relays for further
information.
Remote Alarm input: Alarm I/P
The Remote alarm input is a non-latching input suitable for interfacing to other fire panels. Simply
apply auxiliary –ve (0V) to this terminal and its chosen function will operate as follows;
Mode 1 – Timed Class Change
On application of a 0V trigger, the sounders will operate for 10 seconds, but the control panel will
show no indication, and neither the ‘Fire Relay’ nor the ‘Remote Alarm Output’ will operate.
Mode 2 – Remote Alarm excluding ‘Remote Alarm Output’
On application of a 0V trigger, the sounders will operate, the control panel will show ‘Common Fire’
and ‘Remote Alarm Input’ indication, the ‘Fire Relay’ will change state, but the ‘Remote Alarm
Output’ will not operate. This will reset when the trigger condition is removed.
Mode 3 – Class Change
On application of a 0V trigger, the sounders will operate until the trigger condition is removed, but
the control panel will show no indication, and neither the ‘Fire Relay’ nor the ‘Remote Alarm
Output’ will operate.
Mode 4 – Remote Alarm
On application of a 0V trigger, the sounders will operate, the control panel will show ‘Common
Fire’, ‘Remote Alarm Input’ and ‘Remote Alarm Output’ indication, and the ‘Fire Relay’ and the
‘Remote Alarm Output’ will change state. This will reset when the trigger condition is removed.
Repeater Outputs: Z1, Z2, Z3, Z4, Flt
The repeater output will change to 0v when the relevant state is present, ie, the ‘Z1’ terminal will
become 0v when zone one is in the fire state. An Led or low current relay may be operated if
connected between this terminal and auxiliary 24V positive. Any relays must be dioded. See the
section on relays for further information.
