Applications
1.6 Applications
The FL-PS 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 seven coded or non-coded, synchronized or non-synchronized NACs (Notification Appliance Circuits). Alter-
natively, any output 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 selectable delay. See the DIP switch settings for S1 global options on page 23. All out-
puts can also provide power.
One possible application for the FL-PS 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 command input circuits. When the command input circuits are activated by
the reverse polarity of the NACs, the power supply will activate its corresponding output circuits as programmed by its DIP switch con-
figuration (refer to Table 3.7 on page 25).
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 (except for short circuit conditions). 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 their respective trouble relay.
If an application requires that all outputs activate at the same time, only one NAC is required from the FACP. For this application, the
NAC is connected to command input circuit #1 and the DIP switch is set for this operation.
1.7 Start-up Procedure
1.
Configure the power supply switch as described in "Switch SW1 - Ground Fault Detection" on page 10.
2.
Install the power supply as described in "Installation" on page 12.
3.
Program the power supply as described in "Programming Options" on page 22.
4.
Wire the power supply circuits, referring to the options described in "Trouble Supervision" on page 31 and the application examples
in "Application Examples" on page 37.
5.
Connect primary power source wiring while observing the following:
– Ensure the AC mains circuit breaker is off before making any wiring connections between the mains and the power supply.
– Make certain primary power source is:
120 VAC, 50/60 Hz, 5.0 (6 amp model) 6.2 amps (10 amp model)Run a pair of wires (with ground conductor) from the protected
premises main breaker box to TB4 of the power supply main circuit board.
– Use #12-14 AWG gauge wire with 600V insulation.
6.
Apply power to the power supply using the following procedure:
– Apply AC power by turning on the AC mains circuit breaker connected to the power supply.
– Connect a properly charged battery to connector TB15 on the power supply main circuit board.
7.
Clear trouble history using global DIP switch S1 positions 9 and 10. See DIP switch settings in Table 3.6 on page 24.
