4200 Series Power Supplies

Reliable 12 or 24 VDC Output

The 4202 and 4204 power supplies provide a field selectable 12 or 24 volt DC output.  The required output voltage is accurately regulated to a fraction of a volt, even when operating under maximum and varying load conditions.

DC output is maintained at rated current, #4202-2 amp and #4204-4 amp power supplies, while continuously operating under maximum load.  The extra large heat sink assures a long operating life under extreme conditions.

Totally Protected Circuitry

Both 110 VAC input and DC output is fused to protect the system against overloads and shorts and the switching regulator prevents excessive current draw.  The battery charging circuit and the fire alarm input are thermally protected.

Built-In Battery Back-Up Charger

The battery charging voltage is automatically maintained in excess of the selected DC output voltage to extend battery back-up operational time.  The adjustable trickle charge output will maintain the number of batteries required for emergency back up.

Twin DC Powered Outputs

One output supplies continuous DC power while a second output provides switched DC power through the built-in fire alarm relay

Fail Safe Fire Alarm Input

Innovative design assures DC output cutoff by detecting ground faults in wiring to the fire panel.  Unlike other supply designs that may fail to release the FAR if any wiring insulation is scraped in the connection to the fire panel.

LED Status Indicators

On-board LEDs provide visual indication of power supply operating conditions.  A green LED is illuminated when AC power is present.  The red LED is lit to indicate DC power at the output providing a quick determination of fire alarm input status.  When the amber LED is illuminated a low battery condition exists.
