Lock Is Remaining In Powered State Even When I Send A Lock / Unlock Signal; I Am Trying To Set The Lock Up As Double Access (1 Side Ptl, 1 Side Pto) But It Is Not Working As Expected; Lock Single Beeps Every 2 Seconds; Lock Beeps Once Or Twice Every Time The Lock Locks - Assa Abloy LOCKWOOD 3782 Troubleshooting Manual

Lock is remaining in powered state even when I send a lock / unlock signal

• The lock may function correctly outside of the door but once the lock is fitted to the door the lock will not respond
to the locking signal.
- If the red and green wires are joined and then the locking signal is supplied by switching the negative on the
black wire – the lock will not see a change of voltage (as it is grounded through the door) and will then remain
in the powered state.
• A positive (9-29VDC) lock / unlock signal must be supplied on the lock.
- Wiring should be updated to ensure that the locking signal is switched on the positive side of the supply.
I am trying to set the lock up as double access
(1 side PtL, 1 side PtO) but it is not working as expected
• If the lock is being used in 2 wire mode (red and green wires joined), then this mode will not operate as required –
the lock must be operated in 3 wire mode for this function to operate correctly.
• If the lock is operating in 3 wire mode, is the locking signal on the green wire PtL?
• When entering a power failure state, the PtO side flashes green and then red – this is normal behavior and due to a
minor delay in the power failure being sensed by the lock – the correct failed state is achieved.

Lock single beeps every 2 seconds

• Single beeps every 2 seconds indicates that the lock is not able to move into the locked position – something is
jamming the motor.
o Ensure users of the lock are not holding the handle down for an extended period of time when either
entering or existing through the door. Example: standing in the doorway having a conversation whilst
holding down the handle.
o If furniture is fitted, remove the furniture, with nothing in the hubs and re-try to lock the lock. If the lock
works without the furniture fitted;
- The furniture may be mis-aligned which is causing the hubs to not return fully.
- The furniture return spring may not operate adequately which is causing the hubs to not return fully.
- The door preparation may have a catch which is causing the hubs to not return fully.
o If no furniture is fitted, check correct voltage is being supplied to lock and power supply is able to deliver
specified current.

Lock beeps once or twice every time the lock locks

• Beeping indicates that locking is being delayed or that the motor is drawing excessive current.
o Operate the lock at least 10 times and confirm if the problem is still present.
o Check furniture and voltage as above.

Lock beeps three times on start up

• Triple beeping indicates an error with the setting switches
o Move the setting switches out of their current position and back to required setting – taking care to ensure
the switch has 'clicked' into the required position
o If the switches are in correct position but the lock still triple beeps on start-up, the setting will not change but
remain in previous condition.
• Setting switches may be faulty and the lock should be replaced.
