Other makes of detector will have different connections, but in general they are wired +IN & +OUT to same terminal, -IN to stripe
side of continuity diode, -OUT to non-stripe side of continuity diode. Some makes will connect the +ve to a 470R load resistor, or a
polarisation diode, to enable the detector to work correctly. If detectors other than Fyreye MK II are used the panel may need to be
put into compatibility mode (See section 13)
For more specific device wiring information, please refer to the manufacturers' own instructions.
The termination of each detection circuit must be as indicated on the main PCB (See page 15). The Earthing of the cable screens
should be as shown on page 9.

2.4 SOUNDER CIRCUIT WIRING DIAGRAM

Note: If non-polarised alarm devices (e.g. some types of old mechanical bell, or a relay) are used, then a diode will have to be placed
in line with the device to enable fault monitoring. They may also need a back EMF protection diode.

2.5 AUXILIARY OUTPUT WIRING (VOLTAGE FREE CHANGEOVER CONTACTS)

Auxiliary Fire Output (AUX): Changes over in any fire condition, and be used for driving local fire fighting equipment such as
sprinkler systems, magnetic door holders, air conditioning shut off, etc.
Fault Output (FAULT): This Output is energised in the quiescent condition. In a fault condition, the output relay turns off, to ensure
fail-safe operation even in the event of total power loss. That is, the normally open contact will be closed when there is no fault, and
open when there is a fault. This should be taken into account when any device is connected to the fault relay.

2.6 EXTRA RELAYS

EN54-2 requires a fire panel to have a fault output. However, if the fault output is not being used, the infinity panel has the option
to configure the fault relay as a second fire relay. See Engineering options (Section 13).
