EN54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual
Note 1:
Internal batteries - sealed lead-acid types are
recommended. The following manufacturers/ type are
recommended: Yuasa-NP, Fiamm FG and Jackyl.
Note 2:
The batteries should be replaced at intervals not
exceeding four years. Their lifetime is dependent upon
the ambient temperature; refer to manufacturer’s
technical specification for guidance.
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.
20.0 - 28.5Vdc, (24Vdc nominal) rated at 0.5A.
Note:
If the total alarm current (so 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 Output:
18.5V - 28.5Vdc (24Vdc nominal) rated at 0.5A
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 EN54-2: 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%
Digital Inputs:
0- 32Vdc or contact closure.
Low = 0 - 1.35V
High = 3.15 - 32V.
