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-12/248MP. Audibles can be silenced with only two wires. Additionally, the POWERPATH can provide a temporal
coded signal for appliances that can utilize it.

Terminal Function/Description
IN1+,IN1- These terminals connect to the input voltage source (i.e. 12VDC or
24VDC FACP). The FACP will supply a voltage from 8-33VDC at 5mA.
During the alarm condition these inputs will cause the designated outputs
to drive the notification appliances (designated outputs are set by output
DIP switch banks). During Stand-by on a FACP, a trouble condition on
the designated loop will cause these inputs to trip the FACP by opening
the FACP loop. Alarm condition always overrides trouble to drive output
indicating appliances.
RET1+, RET1- EOLR is connected on these terminals corresponding to IN1+ and IN1-,
or the loop may be continued to other power supplies or appliances
before terminating.
IN2+, IN2- Same as IN1+, IN1- for corresponding terminals.
RET2+, RET2- Same as RET1+, RET1- for corresponding terminals.
C “DRY1” NC Dry contacts are used to actuate the designated outputs. Contacts are
normally closed
and actuate the power supply on contact Open.
Designated outputs correspond to IN1+,IN1-. NOTE: FACP NAC circuit
cannot energize the power supply by these contacts. NOTE: When these
terminals are not in use, a jumper must be connected across them.
C “DRY2” NC Operates the same as IN2+,IN2- for corresponding terminals. When
these terminals are not in use, a jumper must be connected across them.
+OUT1+OUT2+OUT3+OUT4-
Indicating appliances are connected to these outputs (See Examples in
Operation Section). Each output can supply a maximum load of 3.0
Amps, Class "B" or 3.0 Amps Class "A" and can be individually
programmed for Normal Mode, Temporal Mode, IN>OUT SYNC Mode, or
WHEELOCK SYNC Mode. The outputs can be configured as four Class
"B" circuits, two Class "A" circuits, or two Class "B" and one Class "A"
circuits. Outputs are controlled by a designated input (INPUT 1 or 2) as
selected by the DIP switch for that output. NOTE: When the panel has
been set to synchronization mode, IN1 is used for strobe activation and
IN2 is used for audible silence. Individual output control is disabled.

3.1 MODES OF OPERATION
The PS-12/24-8MP POWERPATH can provide a 12VDC or 24VDC output when initiated by a 8VDC to
33VDC appliance (IN1 or IN2) or an open contact (DRY1 or DRY2). The output will remain on until the
deactivation of the input returns it to standby mode.
The outputs can be configured as four Class “B” circuits, two Class “A” circuits, or two Class “B” and one
Class “A” circuits.
Each Class "A" circuit is 3.0 Amps and each Class "B" circuit is 3.0 Amps. Total load for the PS-12/24-8MP
NAC circuits shall not exceed 8.0 Amps.
There are four output modes which can be used with either Class “A” or Class “B” circuits.
NORMAL MODE Used for a constant 12VDC or 24VDC output.
TEMPORAL MODE Provides a temporal output for appliances that can utilize a coded
signal. (i.e. single stroke bells and chimes and some horns) (NOTE:
Do not use with Wheelock AS, NS, RSS appliances.)
IN>OUT SYNC MODE Allows a coded signal or synchronization signal input to be utilized by
the POWERPATH. This signal may come from a FACP, another PS12/24-8MP or a Wheelock Synchronization Module (SM-12/24 or DSM12/24). Audibles can also be silenced.
WHEELOCK SYNC MODE Activates the built-in Wheelock Synchronization Mode for use with
patented synchronized horns and strobes. Audibles can also be

3.4 CLASS “A” OPERATION
Class “A” circuit 1 uses “OUT1” and “OUT3”. Class “A” circuit 2 uses “OUT2” and “OUT4”. When operating
in Class “A” the two circuits must have the same switch settings for the operational mode selected. Switch
SW9 position 1 & 2 on the PC board are in the “ON” position.
• IN1 and/or IN2 can be used for connection to the FACP. The INPUT SELECT Switch (1) selects which
input is to be used to activate the output.
• Board switch SW9 position 1 & 2 control Class “A” or Class “B” configuration. SW9 position 1 controls
Outputs 1 and 3. Switch SW9 position 2 controls Outputs 2 and 4.
• DIP Switch settings for each circuit in the Class “A” output must be set identically.

The PS-12/24-8MP POWERPATH can be configured to have one Class “A” (3.0 Amps) and two Class “B” (2.0 Amps
each circuit) Outputs at the same time. This is done by Switch SW9 position 1 & 2. NOTE: When SW9 position 1 is
on, OUTPUTS 1 and 3 are the Class “A” circuit. When SW9 position 2 is on, OUTPUTS 2 and 4 are the Class “A”
circuit.
COMBINATION OF MODES
• In Class “B” configuration, each output can be set to an independent mode as desired.
• In Class “B”, IN1 or IN2 can be selected to activate any of the outputs desired.
• In Class “A”, OUTPUT DIP Switches must be set identically for each Class “A” output.
