General

The HPF24S may be used in a number of different applications.

It may be used as a remotely-

mounted power supply and battery charger where it can provide up to four coded or noncoded,

synchronized or nonsynchronized NACs (Notification Appliance Circuits).

Alternatively, output

#4 can be used as a door holder circuit which will provide a steady 24 VDC output until an alarm

condition or AC fail condition causes it to drop to 0 VDC following a 10 second delay.

All four

outputs can also provide power.

One possible application for the HPF24S remote power supply utilizes the NAC repeater feature.

In this application, one or two NACs are connected from the main FACP to the remote power

supply control input circuits.

When the control input circuits are activated by the reverse polarity

of the NACs, the power supply will activate its corresponding output circuits as programmed by

SW1 DIP switch configuration (refer to Table 3.1 on page 21).

During the inactive state, the remote power supply supervises its NAC field wiring for short and

open conditions.

If a fault is detected, the power supply will enter a trouble condition and

illuminate the NAC Trouble LED.

When the NACs are activated, the supervision is disabled and

the circuits are no longer supervised.

Supervision of other power supply faults such as low battery,

battery charger trouble, ground fault and AC loss will continue and may be monitored via the

power supply trouble relay.

If an application requires that all four outputs activate at the same time, only one NAC is required

from the FACP.

For this application, the NAC is connected to control input circuit #1 and SW1

DIP switch is set for this operation.
