XFP 16 ZONE ANALOGUE ADDRESSABLE FIRE ALARM PANEL
Connecting Mains to the Power Supply PCB
The panel’s PSU combines the functions of a power supply unit, battery charging unit, battery
monitoring unit and earth fault monitoring unit. It should be positioned in the panel’s enclosure as
shown in Fig. 3 below. DO NOT operate the panel without the Power Supply PCB correctly mounted in
the enclosure with its three PCB retaining screws securely tightened.
CAUTION: DO NOT CONNECT MAINS TO THE POWER SUPPLY PCB UNTIL THE INSTALLATION IS
COMPLETE AND ALL RELEVANT PCBS ARE CORRECTLY ATTACHED WITHIN THE PANEL.
