EN54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual
2.6 Optional Equipment
2.6.1 2-Way Relay PCB (ZIRCON/EN/FFR)
An optional PCB supporting Fire and Fault condition, volt-
free, status outputs may be fitted. When fitted, the PCB
is connected to the Main PCB via connector, PL1.
Note: These relays are only intended to switch SELV.
See Section 8 Specifications .
The PCB is fitted immediately to the left of the Main PCB.
Full instructions for installation are provided with the 2-
way Relay PCB kit (ZIRCON/EN/FFR).
The artwork provided above the wiring termination blocks
shows the Fire and Fault relay contacts with the relays
in a non-energised state. With the panel in its normal
quiescent state, i.e. with no fire or fault conditions present,
the Fire relay is not energised and the Fault relay is
energised. Terminate external wiring as appropriate.
2.6.2 8-Way Relay PCB (ZIRCON/EN/IC)
The panel has provision for fitting up to two optional 8-
way Relay PCBs. A 16-way ribbon cable connects SK2
on the 8-way Relay PCB to the PSU PCB. When two 8-
way Relay PCBs are fitted, a short 16-way ribbon cable
is used to link the two PCBs together: connector SK2 on
the second PCB to SK1 on the first PCB.
The Main PCB must be removed to allow the PCB(s) to
be fitted and for the correct termination of the ribbon
cable at the PSU and 8-way Relay PCB and between
the 8-way Relay PCBs, when two PCBs are fitted.
Full installation instructions are provided with the 8-way
Relay PCB kit (ZIRCON/EN/IC).
