Troubleshooting
No power to the exit device
1. ENSURE that the power connector is connected properly, all
wiring from the power supply is continuous (without opens),
and there are no shorts to ground.
Neither exit device retracts after the control switch is
activated
1. VERIFY
connections.
2. ENSURE exit device wires are properly terminated in the
power supply.
3. VERIFY continuity through power transfer devices such as
wired hinges and door cords/loops.
“Main Power” LED is not lighted
1. ENSURE line voltage is present.
2. CHECK fuse F2 (in the black fuse holder).
3. ENSURE that the primary voltage selection switch SW2 is
properly set.
“Output Power” LED on power supply board is not lighted
NOTE:
If fuse F1 is blown, the wires that run to the exit
device are probably shorted together against the
conduit, door frame, or electric hinge. A meter should
be used to check for shorts.
1. CHECK fuse F1.
2. ENSURE that a fire alarm is connected between J3-9 and J3-
10, or the factory installed jumper between J3-9 and J3-10 is
removed.
