POWERPATH™ NAC POWER SUPPLIES
PS-EXP
Description
Th e Wheel oc k S er ies P S-6 a nd PS -8 ar e 24VDC, fi ltered and
regulated, supervised remote power supply/battery chargers are
used for supervision and expanded power driving capability of Fire
Alarm Notification Appliance Circuits. The PS-6 provides 6 amps of
power distributed across 4 outputs, while the PS-8 provides 8 Amps
across 4 output. In addition the PS-8 provides additional room in
the chassis for accessories like an Addressable Control Module, with
mounting studs.
The Power Supplies may be connected to any 12V or 24V (FWR or
DC) Fire Alarm Control Panel (FACP) by using a Notication 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 ltered and regulated
24VDC, up to four (4) Class “B”, two (2) Class “A”, or two (2) Class
“B” and one (1) Class “A” Notification Appliance Circuits. With the
optional plug-in PS-EXP module the unit supports (8) Class “B” or
(4) Class “A” Notification Appliance Circuits. Additionally, an auxiliary
power output of 2.5 Amps (disconnected upon AC power loss or an
alarm condition) or up to 0.240 A of constant power on the PS-8 and
0.075 A of constant power on the PS-6.
The Wheelock Power Supplies can accommodate 7 or 12 AH batteries
inside its lockable chassis. Using an external battery cabinet it can
charge up to 33 AH batteries (pending UL testing). Two FACP NAC
circuits or two “Dry” contact initiating circuits can be connected to the
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 (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-6 and PS-8 NAC
circuits must not exceed the power supplies rated output.
The Power Suppliesunder non-alarm condition provides independent
supervision for Class “A” and Class “B” FACP NAC circuits. In the
event of circuit trouble, the FACP will be notied via the POWERPATH
steered input (IN1 or IN2). In addition there are two sets of trouble
reporting terminals, one used for AC power loss reporting and the
other for all troubles. The AC power loss reporting, on the common
trouble terminals and on IN1 or IN2, can be delayed for either 30
seconds or 170 minutes. The AC power loss terminals will always
report the trouble within 1 second after loss of AC power.
PS-6
The PS-6 and PS -8 Power Supplies are UL Listed under UL
Standard 864, 9th Edition to be used with any 24 volt Listed
Regulated notification appliances. They include the capability
to synchronize Wheelock strobes and horns and to silence the
horn signal when horn/strobes are operating on two wires.

POWERPATH™ Operating Modes (refer to Installation Manual):
Normal Mode: Provides constant 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 ash.
In>Out Sync Mode: Accepts a synchronization signal on the input to provide a coded output or synchronized output. This signal
may come from a FACP, another POWERPATH or a Wheelock DSM synchronization module. Caution: Do not use strobes on coded
output circuits.
True Input Follower Mode: Accepts a coded signal on the input to provide a coded output with the same timing as the
input. The signal may come from a FACP, another POWERPATH or other coded source. Caution: Do not use strobes
on coded output circuits.
Temporal 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.
