The volt-free relay contacts are rated at
30Vdc with a maximum current of 1A. Do
not exceed the rated voltage and current.

2.5 Remote Control Input
A single 2-terminal input allows remote operation of
the following functions:
Control Level 1 is lowest priority, 5 is highest
priority.
The input is monitored for open and short circuit
faults. Each control level requires a different
resistor load as shown in the above table. A 10K
resistor acts as the end-of-line device for fault
monitoring. See Figure 3 for wiring details.
2.5.1 Class Change
The Class Change function allows all sounder
circuits to be operated for a maximum of 5 seconds.
When the Class Change resistor is applied, the
sounders will operate continuously and then
automatically silence after 5 seconds. No
indications will be given on the panel. The resistor
needs to be removed and applied again if the signal
needs to be repeated.
2.5.2 Alert
The Alert function allows all sounder circuits to be
operated in pulsing mode.
When the Alert resistor is applied, the sounders will
pulse until the resistor is removed. The Alert/Evac
On LED will illuminate on the panel and the internal
buzzer will sound.
2.5.3 Evacuate
The Evacuate function allows all sounder circuits to
be operated in continuous mode.
When the Evacuate resistor is applied, the
sounders will operate continuously until the resistor
is removed. The Alert/Evac On LED will illuminate
on the panel and the internal buzzer will sound. The
Evacuate output will also operate.
2.5.4 Silence Alarms
The Silence Alarms function allows all active
sounder circuits to be deactivated.
When the Silence Alarms resistor is applied, any
active sounder circuits will be deactivated. The
Silence Alarms function is momentary and the
resistor needs to be removed and applied again in
order to re-operate the Silence Alarms function.
2.5.5 Reset
The Reset function allows all standing alarms and
faults to be cleared, returning the panel to the
quiescent state. The Auxiliary 24VDC supply may
also be switched off for 10 seconds if configured to
do so.
When the Reset resistor is applied with the panel in
the alarm condition, any active sounder circuits will
be deactivated, all zone circuits will reset the
detectors, the fire relay will de-energise, the fault
relay will deactivate and all fire and fault indications
will clear. The Reset function is momentary and the
resistor needs to be removed and applied again in
order to re-operate the Reset function.
