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.
