Command access PS2BB Installation Instructions

Connecting to the Fire Alarm Link (if needed)

1. Shut off the 120 VAC to the power supply.
2. Remove the jumper wire from "FIRE"
terminal. (see fig 5)
3. Connect to normally closed fire alarm relay.
4. Restore AC voltage to power supply

TROUBLESHOOTING

Symptom Possible Cause
Possibilty 1- Power supply is too hot,
• Power supply makes a
microprocessor is shutting the power
beeping sound
supply down.
Possibility 2- Fire alarm link removed or
Fire alarm contact broken or loose
• EL Exit device can't fully Possibility 1- Wire gauge from power
retract latch 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
Possibility 1- Dead short or overload
• Green channel LED won't
light up, channel isn't
Possibility 2- Bad solenoid in exit device,
working
or defective interface device between
solenoid and power supply.
• Power supply not working
Possibility 1- AC fuse blown
and red LED not lit.
Possibility 2- Short Circuit

Check to see current draw is exceeding the 2 Amps
continuous rating. If so, eliminate one device that's
connected and check current draw.
If not hooked up to fire/life-safety system, make sure
jumper wire for the fire alarm is properly connected.
If hooked up to fire/life-safety system, make sure system
is functioning correctly
Check with your device manager's wiring

specifications.

Check with your device manager's wiring
specifications.
Re-adjust exit device according to manufacturer's
mechanical recommendations.
Shut off power, detect short, restore power,
channel will reset.
Check solenoid coil resistance and compare to
manufacturer spec. If not close, contact service
represenative.
Replace fuse with 2A Slow Blow 250VAC
5mm x 20mm
If replacement fuse has blown then there
is likely a short circuit in the board & it
will need to be replaced.
