Introduction; Lock Is Not-Responding; What If I Don't Have Enough Wires For 3-Wire Control - Assa Abloy LOCKWOOD 3782 Troubleshooting Manual

Introduction

Since the successful release of the Lockwood Selector Series Electric Mortice Locks, a small number of installation
scenarios warrant some additional information for our customers.
The Lockwood Selector Series Electric Mortice Locks present a number of feature improvements over the previous
3582 series, including a far greater number of field selectable options, inbuilt sounder, LED indicators incorporated
into the lock body and a motor drive design, all best suited to 3-Wire configuration and operation.
As such, please familiarise yourself with the Instruction Manual as installation and programming procedures are
different to the previous Narrow Backset Electric Mortice Lock and refer to the below FAQ section for some more
specific assistance.
Benefits
• Confirm lock has power by checking heartbeat LED. Remove top screw from cover (front) plate and looking for a
blue LED flashing every 2 seconds
o If the lock is powered (heartbeat is flashing) but still not responding:
- If using 2 wire mode, confirm the red and green wires are joined together and there is 9-28VDC present
between red/green and black connections depending on locking signal.
- If using 3 wire mode, confirm red wire is permanently powered (+9-28VDC) and green wire is switched
(9-28VDC) on / off to send the lock/unlock signal.
o If the lock is not powered (heartbeat is not flashing)
- Remove lock from door and power using a micro-USB connector attached to a power bank, PC or mobile
phone charger – if the heartbeat LED now operates:

What if I don't have enough wires for 3-Wire Control?

Most Access Control systems share Common inputs for their Monitored Inputs including Door Position, Deadlatch,
Lock Status, REX & KOM.
If this is the case with the Access Control system you're using and you have sufficient wires at the Lock for the
Monitoring outputs, you can common together at least two of the Monitored Outputs common outputs to salvage a
spare wire for 3-Wire control.
Any or all of the following Commons on the Lock Outputs can be connected together: 9, 10, 14 & 16, allowing for a
minimum of 6 wires to achieve individual monitoring outputs for all functions being Door Position, Deadlatch, Lock
Status, REX & Key Override.
Using this scenario, a minimum of 9 wires will enable full monitoring and control of the lock in 3-wire mode.
Additional wires could also be salvaged by placing in Series several Monitoring Outputs to a single Output, such as
Deadlatch and Lock Status to provide one output to the Access Control system. Door Position may also be included
in the One Output scenario, saving an additional wire.
Due to their unique functions, REX and KOM outputs should remain as individual outputs.

• Test the cable at the door – there should be 9-28VDC present between the red and black wires.
• Test the locking signal – there should be 9-28VDC present between the green and black wires – this
should change between off and on when a locking signal has been sent.
o If the lock can be powered by USB and there is correct power on the cabling:
- Remove all power from the lock for 2 minutes and check the setting switches on the
back of the lock are set correctly (lock may have been powered in Escape-Escape and
then the switches were moved)
