1.0 INTRODUCTION AND SPECIFICATIONS:

1.1 INTRODUCTION

The PS-12/24-8MP 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-12/24-8MP may be connected to any 12VDC 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 12VDC or 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 of 3.5 Amps is provided, which can be reset. The PS-12/24-8MP also contains a battery charger
capable of charging either 7 or 12 Amp/Hour (AH) of battery backup.
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 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-12/24-8MP NAC circuits shall not exceed 8.0 Amps.
The PS-12/24-8MP 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-
8MP. Audibles can be silenced with only two wires. Additionally, the POWERPATH can provide a temporal
coded signal for appliances that can utilize it.
