FL-PS Series Instruction Manual —
P/N LS10227-001FL-E:B 3/29/2021
Section 1: System Overview
The FL-PS6 is a 6 amp and the FL-PS10 is a 10 amp remote power supply with battery charger. Both models provide ADA compatible
strobe synchronization and a filtered 24 VDC output that can be configured to drive five (6 amp model) or seven (10 amp model) Class
B NACs (Notification Appliance Circuits). NAC circuits can be configured for Class A wiring with the optional ZNAC-PS Class A con-
verter module. NAC output circuits may be configured as 24 VDC resettable or non-resettable power outputs, or Class D door holder
outputs. The input circuits, which control the power supply operation, are triggered by the reverse polarity of a NAC or by a 12 VDC or
24 VDC power source. The FL-PS power supplies are compatible with 12 VDC and 24 VDC control panels.
The FL-PS6C and FL-PS10C offer the same features as the FL-PS6 and FL-PS10 respectively, but are intended for Canadian applica-
tions and adds an additional relay for ground fault reporting. Unless otherwise specified, the information in this manual applies to all
models.
1.1 General
FL-PS power supplies can be used as remotely mounted power supplies and battery chargers to power non-coded or coded NACs. The
Main FACP (Fire Alarm Control Panel) NAC(s) is connected to the remote power supply input circuit(s). When the command input cir-
cuit activates due to reverse polarity of the NAC from the FACP, the power supply will activate its Notification Appliance Circuits.
During the inactive or non-alarm state, the power supply supervises its NAC field wiring for short and open conditions. AC fail, battery,
charger and ground fault troubles will also be monitored by the power supply and will activate the AC Fail, Battery Fault, and Ground
Fault relay, respectively. If a NAC fault is detected, the input end-of-line will open to indicate the fault to the main panel.
If an alarm condition occurs and the NAC is activated, the supervision is disabled and the Notification Appliance Circuit is no longer
supervised (except for shorts). Supervision of other power supply faults such as low battery, overcharged battery, ground fault, and bat-
tery charger trouble will continue and will be monitored by their respective trouble relays.

1.3 Specifications
Refer to Figure 1.1 on page 10 for terminal locations.
Primary AC Power - TB4
•

NOTE:
The FL-PS6 uses the same PCB layout as the FL-PS10, however some terminals will be depopulated, leaving the FL-PS6 with five
output circuits and two input circuits.
