| Problem |
Possible Solutions |
| Strike does not operate
when energized |
- Check for proper voltage being supplied to
the strike.
- Check all wiring.
|
| Strike operates intermittently |
- Check for loose wire connection
|
| Solenoid overheating
or burned out |
- Check for proper alignment between strike
keeper and bolt, realign strike if necessary.
The keeper may not be returning to the fully
locked position. Check operation with
the door open. If the strike re-locks,
check the horizontal alignment between the strike
keeper and the latch bolt. There is a
1/8" (3.2mm) horizontal adjustment available.
Shift the strike mechanism behind the faceplate
before tightening the mounting screws.
If vertical alignment is off, reposition the
face plate.
- Check the locking cam spring to insure it
is moving the locking cam into the locked position(Non-Fail-Safe)or
the unlocked position (Fail-Safe)
- Check the solenoid assembly to insure the
solenoid plunger is moving freely.

| Improper indication
(LCM,
LBM,
LBMLCM
or LCBDM) |
- Check wiring
- Check latch bolt or dead bolt for proper engagement
with the switch tripper.
- Check switch actuator arm, re-bend if necessary.
- Check continuity of indication switches, common
to normally open, common to normally closed.

| Solenoid plunger binding
in solenoid. (Plunger will not extract or retract) |
- Check alignment between solenoid plunger and
cam.
|
| Strike is not re-locking
or is not unlocking. |
- Check for proper alignment between strike
keeper and bolt, realign face plate if necessary.
The keeper may not be returning to the fully
locked position. Check the strike with
the door open, if the strike re-locks check
the horizontal alignment between the strike
keeper and the latch bolt. there is a
3/16" horizontal adjustment between the
strike assembly and the face plate. If
vertical alignment is off reposition the face
plate.
- Check the locking cam spring to insure it
is moving the locking cam into the locking position
(no-fail-safe) or the unlocking position (fail-safe).
- Check the solenoid assembly to insure the
solenoid plunger.
|
| Buzzing solenoid |
- Realign solenoid on AC strikes. Replace rectifier
on DC strikes.
