Main Supply Circuit
The AC terminals are located on the power supply board. The power supply board supervises the main AC
power and provides indication that the AC power is absent.
Figure 1
The terminals are rated at 120 VAC/240 VAC 50/60 Hertz and are marked so accordingly on the board. The
earth ground connection is marked as “G” and is the furthest connection from the line voltage connection.
The AC input power ratings:
Maximum of 5.1A at the nominal 120 VAC rating.
Maximum of 3A at the nominal 240 VAC rating.
Rechargeable Battery Circuit
The battery charging circuit is provided on the power supply board. Terminal connections are provided to con
-
nect wire leads for battery connection. The battery must be a recognized or listed sealed lead acid battery or
equivalent.
The battery charging voltage is approximately 27.3 VDC and the circuit is supervised. The battery circuit is
protected with a non-replaceable 7 amp poly switch located on the main circuit board. The maximum battery
charging circuit is 1.0 amp DC.
The battery circuit is rated for 8 to 55 AH batteries and the cabinet will house up to two 18 AH batteries. The
batteries will operate the panel for at least 24 hours and 5 minutes of alarm. In order to determine the minimum
size batteries for standby and alarm times desired, the installer must complete a battery calculation work sheet
in order to determine the minimum battery size for a particular application. For reference, the battery calcula
-
tion work sheet is attached as Appendix A. Complete standby battery calculations must be completed to ensure
adequate battery sizes are provided.
