1.0 INTRODUCTION AND SPECIFICATIONS:

1.1 INTRODUCTION

The POWERPATH NAC Extender Power Supply is available in two models: the PS-8 and the PS-6. The PS-8
differs from the PS-6 in the NAC output current and in the enclosure size and the PS-8 enclosure can mount up
to two addressable control modules. All other features, indicators and capacities are the same.
The PS-8 is an 8 Amp, 24VDC, filtered and regulated, supervised remote power supply/charger used for
supervision and expanded power driving capability for Fire Alarm Notification Appliance Circuits. The PS-8 may
be connected to any 12VDC or 24VDC Fire Alarm Control Panel (FACP) by using Notification Appliance Circuits
(NAC) or a "Dry Contact(s)". Primary applications include NAC expansion (supports ADA requirements) and
auxiliary power to support system accessories. This unit provides filtered and regulated 24VDC, 8 Amp up to
four (4) Class "B", two (2) Class "A", or two (2) Class "B" and one (1) Class "A" Notification Appliance Circuits.
Additionally, an auxiliary power output can provide constant power of up to 0.24 Amps for 24 hours and up to
0.02 Amps for 60 hours, or managed power up to 2.5 Amps in a non-alarm condition and when AC power is
applied to the panel. The PS-8 also contains a battery charger capable of charging up to 33 Amp/Hour (Ahr) of
battery backup. The PS-8's NAC outputs can also be used as UL-1481 Compliant power supply outputs. When
configured this way, the maximum continuous current rating is 3 Amps per power supply output and 4 Amps
maximum total current for all continuous duty power supply outputs.
The PS-6 is a 6 Amp, 24VDC, filtered and regulated, supervised remote power supply/charger used for
supervision and expanded power driving capability for Fire Alarm Notification Appliance Circuits. The PS-6 may
be connected to any 12VDC or 24VDC Fire Alarm Control Panel (FACP) by using Notification Appliance Circuits
(NAC) or a "Dry Contact(s)". Primary applications include NAC expansion (supports ADA requirements) and
auxiliary power to support system accessories. This unit provides filtered and regulated 24VDC, 6 Amp up to
four (4) Class "B", two (2) Class "A", or two (2) Class "B" and one (1) Class "A" Notification Appliance Circuits.
Additionally, an auxiliary power output can provide constant power of up to 0.075 Amps for 24 hours, or
managed power up to 2.5 Amps in a non-alarm condition and when AC power is applied to the panel. The PS-6
also contains a battery charger capable of charging up to 33 Amp/Hour (Ahr) of battery backup. The PS-6's
NAC outputs can also be used a UL-1481 Compliant power supply outputs. When configured this way, the
maximum continuous current rating is 3 Amps per power supply output and 4 Amps maximum total current for
all continuous duty power outputs.
Each NAC Extender Power Supply allows two FACP NAC circuits or two "Dry" contact closures to activate it
when connected to the inputs. These inputs can then be directed to control supervision and power delivery to
any combination of the four (4) outputs.
Each NAC output is rated at 3.0 Amps (Class "B") or 3.0 Amps (Class "A") and can be programmed to
generate a steady or Code 3 Temporal Horn sound, and a strobe output under alarm condition. Total
load for the PS-8 NAC circuits shall not exceed 8.0 Amps. Total load for the PS-6 NAC circuits shall not
exceed 6.0 Amps.
Each NAC Extender Power Supply, under non-alarm condition provides independent loop supervision for Class
"A" and Class "B" FACP NAC circuits. In the event of a loop trouble, the FACP will be notified via the panel
steered input (IN1 or IN2). In addition there are common trouble output terminals (used to indicate a loop
trouble) and common trouble input terminals (used generically by any initiating circuit).
Wheelock horns/strobes, strobes and horns with synchronizing capability can be utilized with both the PS-8 and
the PS-6. Audibles can be silenced with only two wires outputs. Additionally, the POWERPATH can provide a
temporal coded signal for appliances that can utilize it.
