Electrical Specifications
Input Power
The PFC-9000 operates on a nominal 120 or 240 VAC with a minimum and maximum line voltage of 102 VAC and 132 VAC
or 204 VAC and 264 VAC respectively. A resettable 4-Amp fuse is installed on the primary side of the transformer-input power.
The transformer is a 24-volt transformer that provides 12 Amps of power to the panel. For more detailed information on power
consumption refer to the battery calculation sheet.
The fire alarm panel must be connected to a dedicated circuit and should be wired using 12 AWG wire through the side conduit
entrance. The black (hot) must be connected to the line, the white to the neutral (N) and the green to the ground. An earth ground
must also be connected to the cabinet.
Battery Backup Requirement
The PFC-9000 is capable of charging standby batteries from 17 to 40 amp-hours. The batteries should be sized according to the
battery calculation performed that accounts for all standby currents and power requirements when the panel is in alarm.
When the panel communicates to a Central Station, a minimum of 24 hours of stand-by current and five minutes of alarm current
is required. When communicating to a Remote Supervising Station, a minimum of 24 hours of battery stand-by is required
followed by five minutes of alarm current.
The cabinet will house up to 18 amp-hour batteries; larger batteries will need to be housed in a separate cabinet.
A 20-amp fuse on the main board protects the battery circuit. If the panel is showing a trouble condition of missing batteries, and
the batteries are connected and meter to the correct voltages, then the fuse should be replaced.
Per the National Electrical Code, the fire alarm circuit breaker should be marked red and labeled.
Permanent installations require AC power and battery backup to be supplied to the panel. Failure to properly size batteries
could result in the panel prematurely shutting down when there is a loss of AC power.
17 AH batteries are the minimum capacity batteries allowed in the PFC-9000 series. The installation of batteries with a
capacity less than 17 AH will damage the batteries and panel.
Connect AC power to panel followed by batteries. Observe polarity when connecting batteries. Failure to do so may result
in damage to the batteries, battery leads, or panel.
