PS-12-24-8 CP
POWERPATH™
NAC POWER SUPPLIES
Description
POWERPATH™ Series PS-12/24-8CP and PS-12/24-8MP are
power limited 8 amp power supply/chargers used to expand
the supervised power capability of a fire alarm control panel
(FACP) for notification appliance circuits (NAC).
The PS-12/24-8CP provides up to 200 milliamps of continuous
auxiliary output that can be used for control functions during
alarm (or up to 60 milliamps for 60 hour battery requirements).
The PS-12/24-8MP provides up to 3.5 amps of auxiliary output
that is available only during nonalarm condition for such
applications as door holder systems.
Both models provide regulated and filtered 12 or 24 VDC output
to four (4) Class “B” or two (2) Class “A” circuits. Each Class “B”
circuit has a rating of three (3) amps with a total output of up to
eight (8) amps. Each Class “A” circuit is rated at three (3) amps.
Two (2) Class “A” or Class “B” inputs from an FACP and two (2)
dry contact inputs are provided to trigger the outputs. The units
accept either 12 or 24 VDC inputs and provide 12 or 24 VDC
outputs. Both units support a full 8 amps of notification power
even if the battery is in a degraded mode and only AC power is
connected.
POWERPATH™ Series PS-12/24-8CP and PS-12/24-8MP are
compatible with all Wheelock 12 or 24 VDC Life Safety Notification
Appliances and with their Patented BUILT-IN SYNCHRONIZED
MODE feature, they can control and operate all of Wheelock’s
Synchronized Notification Appliances, including silencing
audibles while maintaining strobe activation.

Normal Mode (Class A)
POWERPATH™ Operating Modes (refer to Installation Manual):
Normal Mode: Provides constant 12 VDC or 24 VDC output upon initiation by a
voltage to input IN1 or IN2 or by a contact opening on DRY1 or DRY2. The unit returns
to standby mode when the input is deactivated.
Wheelock Sync Mode: Provides signals for synchronization of patented Wheelock
audible and strobe notification appliances. Audibles can also be silenced in this mode
while the strobes continue to flash.
In>Out Sync Mode: Accepts a coded signal or synchronization signal on the input to
provide a coded output or synchronized output. This signal may come from a F ACP,
another POWERP A TH or a Wheelock SM or DSM synchronization module. Caution:
Do not use strobes on coded output circuits.
T emporal Mode: Codes the output voltage in a code-3 temporal pattern to drive audible
appliances such as horns, bells or chimes. Caution: Do not use strobes on coded
output circuits.
