Installation Instructions
PS2/PS2BB
The PS2 series is designed to power Command Access modied exit devices, Von
Duprin EL devices, or Dor-o-matic EL devices. The PS2 series is a regulated, linear
power supply rated at 2 Amps @ 24VDC. It’s state-of-the-art, solid-state design oers
a exible and cost eective solution. Its built-in surge capabilities allow it to power
up to two latch-retracting exit devices, when used with Command Access power
modules. The PS2 series is a feature-rich 24VDC power supply that oers solid-state
Inputs/Outputs, re alarm link, optional battery charging circuitry and other standard
features to give you the exibility and control to do the job right.

Symptom Possible Cause Solution
• Power supply makes a
beeping sound
Possibilty 1- Power supply is too hot,
microprocessor is shutting the power
supply down.
Possibility 2- Fire alarm link removed or
Fire alarm contact broken or loose
Check to see current draw is exceeding the 2 Amps
continuous rating. If so, eliminate one device that’s
connected and check current draw.
EL Exit device can’t fully
retract latch
Possibility 1- Wire gauge from power
supply to exit device too small
Possibility 2- Distance from Power
Supply. to exit device is too far
Possibility 3- Exit device out of
adjustment
Check with your device manager’s wiring
specications.
Green channel LED won’t
light up, channel isn’t
working
Possibility 1- Dead short or overload
Possibility 2- Bad solenoid in exit device,
or defective interface device between
solenoid and power supply.
Shut off power, detect short, restore power,
channel will reset.
Power supply not working
and red LED not lit.
Possibility 1- AC fuse blown Replace fuse with 2A Slow Blow 250VAC
5mm x 20mm
TROUBLESHOOTING
Re-adjust exit device according to manufacturer’s
mechanical recommendations.
Check with your device manager’s wiring
specications.
Check solenoid coil resistance and compare to
manufacturer spec. If not close, contact service
represenative.

•
If not hooked up to re/life-safety system, make sure
jumper wire for the re alarm is properly connected.
If hooked up to re/life-safety system, make sure system
is functioning correctly
Doc. #20020_A
Possibility 2- Short Circuit If replacement fuse has blown then there
is likely a short circuit in the board & it
will need to be replaced.
Connecting to the Fire Alarm Link (if needed)
1. Shut o the 120 VAC to the power supply.
2. Remove the jumper wire from “FIRE”
terminal. (see g 5)
3. Connect to normally closed re alarm relay.
4. Restore AC voltage to power supply

STEP 1 - Mount the power supply
STEP 2 - 120VAC wiring connection
STEP 3 - Wiring the Exit Devices
1. Make sure 120VAC service is o at power supply
PS2 (Breaker should be shut o).
2. Make sure 120VAC supply wire is rated at 90° C or
higher.
3. Connect 120VAC supply wire to the terminal block.
Connect ground to pigtail attached to enclosure.
4. Restore AC power to power supply. Red LED should
now be on.
5. Proceed to step 3.
1. Shut o breaker supplying AC power to the
power supply.
1. Find a cool and dry location to mount
the power supply.
Wiring Batteries (Batteries not included)
1. Turn on 120VAC to power supply
2. WARNING: Make sure battery polarity is correct before you proceed.
3. Hook up batteries with battery leads as shown in g 4. The enclosure will
accommodate (2) 7AH 12V batteries.
NOTES:
1. When installing batteries for the rst time or replacing old batteries make sure the batteries installed are fresh.
2. We recommend you label the battery with the date the batteries were installed. Most battery manufactures recommend the
batteries be replaced after 4-5 years of service. You may want to check with your battery manufacturer when establishing
a “replace by” date.

2. Using the four mounting holes in the
power supply box, secure the box to a
wall or other solid surface.
(Note: The box is designed & approved
for indoor use only.)
3. Proceed to step 2.
1. For UL Installations, the power supply must be installed in the protected area within an
Access Controlled room
2. Must be Installed with in accordance with the National Electrical Code, ANSI/NFPA 70.
3. Must be Installed with in accordance with Local authority having jurisdiction.
4. The AC input wiring shall
a. be in conduit,
b. be minimum No. 18 AWG wire,
c. maintain ¼ inch spacing between non power-limited wiring, and
d. be fail safe to meet the requirements of NFPA 101, Paragraph 7.2.1.6.
