EN 54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual
Outputs:
Sounder Circuits:
Two outputs configurable as sounder, fire routing output or
fault output and each rated at 0.5A. The sounder and fire
routing outputs are monitored.
18.0 - 28.5Vdc, (24Vdc nominal) rated at 0.5A.
Note: If the total alarm current (sounders + fire + Auxiliary output)
exceeds a total load of 1A, you must check the total
alarm load using the Battery Calculation in Section 9.
Zone Circuits:
Factory-supplied two, four or eight detector zones.
The quantity of detectors per zone equals 2.0mA divided by
the individual detector’s quiescent current rating - see
manufacturer’s data sheets - e.g. for a detector quiescent
rating of 75μA; the quantity of detectors:
= 2.0mA ÷ 75μA = 26 detectors.
Auxiliary DC Output:
18.0V - 28.5Vdc (24Vdc nominal) rated at 0.5A
Note: The length of any cables connected to the auxiliary
output must not exceed 30m.
Optional 2-Way Relay PCB providing:
A Fire Relay Output
A Fault Relay
Output
Each relay is rated at 30Vdc, 1A.
Note: To comply with the requirements of EN 54-2: 8.8, if
the 2-way Relay PCB is not fitted one of the sounder
circuits must be configured as a fault output.
Optional 8-Way Relay PCB providing up to 8 outputs per
PCB (two PCBs may be fitted). Relay contact functions are
configurable using jumper links to provide the following:
Repeat Zonal Output or
Coincident Zonal Output or
Repeat Zonal Output (zones 1-4) and Shop Interface
Outputs or
Inputs and Shop Interface Outputs
Max current (per PCB):
Quiescent - 0.1mA
Alarm/ all active - 80.1mA
Each relay is rated at 30Vdc, 1A
Fire resistor: Nominal 470R ±5%
Optional 4-way sounder PCB supporting four configurable
monitored outputs and two configurable input circuits.
Various preset combinations of input and output functions
are selected via a DIP switch. By using the supplied end-of-
line termination the 4-way sounder PCB is able to provide
sounder, fire routing and fault routing outputs as required
by EN 54-2 and ISO 7240-2. These outputs are all monitored
for partial-short and partial-open circuit faults as required
EN 54-2: &
ISO 7240-2 7.7.1
One output on the panel
must be configured as a fire
output.

PSU PCB circuits do not
comply with the
requirement for partial-
open and -short circuit
fault monitoring on fire
alarm device, fire routing
and fault routing outputs.
