EN 54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual
6 Commissioning
6.1 Introduction
It is recommended that the control panel is powered up
and tested before connecting the field devices.
6.2 Preliminary Checks
Before connecting the mains power to the panel, check:
1 The earth lead from the safety earth post is connected
to the earth tag on the Main PCB.
2 That the EOL devices are correctly terminated in the
zone input and sounder output terminals and no
external wiring terminations have been made.
6.3 External Wiring
6.3.1 Zone Wiring - New Installation
Zone wiring should not be connected to the panel at this
stage.
6.3.2 Zone Wiring - Retrofit Installation
Zone wiring should not be connected to the panel at this
stage.
Refer to Section 7.5.6 EOL Device Type for details on
how to change the configuration of the panel, as
necessary, to support 4k7 resistor EOL devices.
Note: Where Active-End-of-Line (AEOL) devices exist
on zone wiring these may need to be replaced
with 0.47μF capacitor EOL devices. EOL device
type options are described in Section 6.7 Zone
Wiring.
6.3.3 Sounder Circuits
Sounder output circuit wiring should not be connected
at this stage.
6.3.4 2-Way Relay PCB (Optional)
If the 2-way Relay PCB (PN: 020-713) is to be fitted,
refer to the installation instructions supplied with it. Refer
to Section 7 Configuration for details on configuring
the two relay output circuits.
6.3.5 8-Way Relay PCB (Optional)
If fitting 8-Way Relay PCB(s) (PN: 020-747) refer to the
instructions supplied with it.
6.3.6 4-Way Sounder PCB (Optional)
If fitting 4-Way Sounder PCB(s) (PN: 020-772) refer to
the instructions supplied with it.
