1.0 INTRODUCTION AND SPECIFICATIONS

1.1 INTRODUCTION

The PS-12/24-8 POWERPATH is an 8 AMP, 12/24VDC, filtered and regulated, supervised remote power supply/charger used
for supervision and expanded power driving capability for Fire Alarm Notification Appliance Circuits. The PS-12/24-8 may be
connected to any 12 or 24VDC Fire Alarm Control Panel (FACP) by using a Notification Appliance Circuit (NAC) or a "Dry
Contact". Primary applications include NAC expansion (supports ADA requirements) and auxiliary power to support system
accessories. This unit provides filtered and regulated 12 or 24VDC, 8 AMP supply to 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 that can be
reset is provided. The PS-12/24-8 also contains a battery charger capable of charging either 7 or 12 AMP/Hour (AH) of battery
backup. The PS-12/24-8 can only provide a maximum load of 8 amperes for 5 minutes with a 7AH battery or 15 minutes with a
12AH battery.
Two FACP NAC circuits or two "Dry" contact closures can be connected to the POWERPATH inputs. These inputs can then be
directed to control supervision and power delivery to any combination of the four (4) outputs.
Each output is rated at 2 AMPS (either Class "A" or Class "B") and can be programmed to generate a steady or Code 3
Temporal horn sound and a strobe output under alarm condition. A maximum 4 AMP output is achieved by paralleling 2
outputs (Class "B" only).
The PS-12/24-8 under non-alarmed 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 POWERPATH 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 the PS-12/24-8. Audibles can be
silenced with only two wires. Additionally, the POWERPATH can provide a temporal coded signal for appliances that can
utilize it.
