With all cables in position, connections can now be made to the circuit board mounted on
the front plate. All connections must be made with power off.
3. Terminal details
3.1
Power terminals 24V IN/24V OUT
These are the power supply terminals. The polarity of these terminals is very important.
If connecting multiple FirePro. FPC-2 V2 units to a single power supply the 24V DC must
be wired as shown in Figure 3 below.
Use a minimum cable size of 1.5mm
2
and a maximum length of 100 metres or a
maximum cable size of 2.5mm
2
and a maximum cable length of 160 metres.

3.2
Detection terminals
These terminals are for the connection of a conventional type 24V smoke detector or
other another detection device such as linear heat detection cable, see figures 4 and 5. A
6K8 end of line monitoring resistor is fitted to these terminals. This must be removed
and place across the end of the detection circuit wiring to provide open circuit monitoring
for the detection cable.
Note:
Automatic smoke detectors are polarity sensitive so polarity should be observed. If a
short circuit takes place on the detection line (either by linear heat detector activation or
smoke detector activation [470 Ohms] or by accident), then the panel will immediately
proceed to activation.
