CAST ZFP Analogue Addressable Fire Alarm Panel

5.16 Connecting Mains to the Panel's PSU

THE PSU IS CLASS 1 EQUIPMENT AND MUST BE EARTHED.
The panel's EN 54-4 PSU is a mains to regulated DC power supply providing 5A @ 24Vdc nominal. Combining
the functions of a PSU, battery charging unit and battery monitoring unit, it is fully compliant with EN 54-4:1997
+ A1:2002 + A2:2006. For compliance with EN 54-4 the PSU must be closely coupled with the CIE.
Remove the protective cover of the PSU and terminate the mains cable at the power supply's PCB connector
block CONN1 (see Fig.10 below). After terminating, refit and secure the cover.
DO NOT CONNECT MAINS SUPPLY TO THE PSU UNTIL THE INSTALLATION IS COMPLETE
AND THE PANEL IS READY TO BE TESTED.
