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.

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
• 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.
• 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:
- Test the cable at the door – there should be
9-28VDC present between the red and black
wires.
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.
Lock is not-responding
What if I don’t have enough wires for 3-Wire Control?
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 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.
• 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)

We strongly recommend that 2-Wire mode
is not used, specifically in PTO mode. Please
see FAQ “What if I don’t have enough wires
for 3-Wire Control” first to determine if this
scenario will assist you.
If you must use 2-Wire Control, the Red & Green
wires can be connected together and switched
to control the lock. This can also be achieved
using the 9 – 12 adaptor (SP3782EL-251)
which joins the red and green wires together
and includes the new Lock Status monitor in
series with the DPS reed switch and Deadlatch
monitors.
In 2-Wire PTO (Fail Secure) mode, the lock
will receive no power when in the Locked
state. When the Access Control system sends
an Unlock command to the Lock, it will send
power to Unlock the door. This power must
be present for at least 5 seconds to enable the
energy storage capabilities within the lock to
regenerate so that the Lock can Re-Lock when
the power has been removed.
3-Wire Control is when the Lock receives constant
power on the Positive (Red) and Negative (Black)
wires and the triggering control is achieved using
the Control Wire (Green) which is a Positive (+)
trigger.
3-Wire Control using a Separate Power Supply
for the Control/Trigger
When using a different Power Supply for the
Control Line (Green Wire) to that of the Power
Supply to the Lock (Red & Black Wires), the
Common/Negative line of both Power Supplies
must be tied together. This allows the Control
wire to complete the circuit and actually trigger
2-Wire Control
3-Wire and 2-Wire Control Diagrams
the Lock operation. Failure to connect the two
negatives will make the lock inoperable.
2-Wire Control
2-Wire Control is where the Lock receives a constant
Negative (Black) and the Lock status changed using a
Positive trigger on both the Positive (Red) and Control
(Green) wires, which are tied together.
Lock Control must be switched on Positive ONLY. As the
Lock Body is grounded, if the Door Frame and Door are
also Grounded and switching is performed through the
Negative/Ground wire, the Lock will remain energised
constantly.
Therefore, when configuring the Door Unlock
functions in the Access Control system
programming, do NOT enable a “Door Relock
on Door Open” function. This function will
normally attempt to relock the Door as soon
as the Door Position Input detects that the
door has been opened after an Access Granted
command. This will then cut power to the lock,
quite possibly within one second of the door
being unlocked.
The above scenario does not provide enough
time for the Lock’s energy storage to be
recharged and the Lock will have insufficient
energy to relock.
Also ensure that the programmed ‘Door Unlock’
period is set to a minimum of 5 Seconds. This
will ensure that power is supplied for a sufficient
amount of time for the Lock’s energy storage
to be fully charged, allowing it to successfully
perform its locking functions when the power
has been removed.

Lock is not locking according to the way
I have set the switches:
The setting switches will not take effect until the lock has fully
powered down. Disconnect all power from the lock and wait at
least 2 minutes and then retry.
•If the problem persists, return lock for investigation
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.
•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.
•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.
•If no furniture is fitted, check correct voltage is being
supplied to lock and power supply is able to deliver
specified current.
Lock beeps three times on start up:
Triple beeping indicates an error with the setting switches
•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
•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.
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.
•Operate the lock at least 10 times and confirm if the
problem is still present.
•Check furniture and voltage as above.
•specified current.

Deadlatch monitor is not working:
Confirm correct wires are being used by testing with a multi-meter
•Signal should be open when the auxiliary bolt is out and
closed when auxiliary bolt is depressed
Check the door gap does not exceed 5mm (6.5mm is absolute
maximum)Check that the auxiliary bolt fully extends when the door
is open
•If not, loosen furniture, lock and cover plate mounting
screws and re-adjust to ensure proper operation of the
auxiliary bolt
REX (Request to Exit) is not working:
Confirm correct wires are being used by testing with a multi-meter
•With NO/NC switch to NC - signal should be open when the
handle is turned and closed when the handle is released
REX will not operate when the lock is set to Escape-Escape
REX operates on the handle that is set to Escape only
Confirm that the NO/NC (Normally Open / Normally Closed) switch
on the side of the lock is set correctly and switch has travelled to
selected side fully.
Door position switch is not working:
Confirm correct wires are being used by testing with a multi-meter
•Signal should be closed when a magnet is placed below
bottom mounting screw and open when magnet is
removed.
Confirm the door position magnet is installed at correct position
below the strike.
Confirm door position magnet can attract a ferrous item.
Lock double beeps every 6 seconds:
Double beeping every 6 seconds indicates that the lock cannot
communicate with the motor.
•Lock should be returned for investigation.

Lock status monitor is not working:
Confirm correct wires are being used by testing with a multi-meter
•Signal should be open when the lock is unlocked and closed
when lock is locked
Lock status monitor state will only change when the lock is
powered (the lock will only change state when powered as well)
LED is not active:
Lock is supplied with LEDs de-activated. Refer to instructions on
how to activate the LEDs
Having the LED’s programmed as active can also assist in fault
finding the installation
LEDs turn off after 10 seconds:
The LEDs will turn off after 10 seconds when being powered in 2
wire mode (red and green wires joined)
•Wire lock in 3 wire configuration if continuous LED
operation is needed
LED shines red briefly and then green after
sending unlocking signal:
The LED indicates the status of the lock and will only change to
green once the lock has confirmed that it is definitely unlocked.
If the lock is being powered in 2 wire PtO – this will result in the
LED being off and then when a locking signal is received, the LED
will be red for a fraction of a second before changing to green once
unlocked.
•2 wire PtO is not recommended
LED is not visible after fitting furniture:
4800 lens furniture requires an extra hole to be drilled above top
furniture mount hole – has this been drilled
•If yes, remove furniture and confirm LEDs are operating on
lock and inspect for obstructions

There is no room for the cable when installing
in a timber door:
The cable boot is only intended for aluminum frame installs and can
be removed for timber door installations
Ensure door preparation is correct as the 3782EL requires a
lengthened mortice compared to a mechanical timber fix door
preparation.
Can I leave a USB cable connected to the lock
but power it via the main connector:
This is not recommended
I have old LED furniture that I would like to
re-use, is there an adaptor kit:
No, new and improved 4800 lens furniture will need to be
purchased.
I have an old 3582EL to replace, is this lock
interchangeable:
The lock is completely backwards compatible and a 9 – 12 pin
adaptor (SP3782EL-251) is available
•2 wire PtO is not recommended
If using LED lens furniture, additional holes will be required above
the top furniture mounting hole

www.assaabloy.co.nz

I have a retro-fit with LEDs (power is being
sent on old green wire to continuously power
LEDs), will I have to re-wire the installation:
The lock is retro-fittable to the old lock and a 9 – 12 pin adaptor
(SP3782EL-251) is available.
•The 9 – 12 pin adaptor will operate the lock in 2 wire mode
and thus the LEDs however in PTO mode, the LED’s will
operate for a few seconds only.
•2 wire PtO is not recommended
I am trying to set the LEDs on site, how can I
power the lock:
The lock can be powered via a micro-USB connector connected to
a power bank, PC or mobile phone charger or it can be powered by
the main connector with a 9 or 12V battery connected to the red
(+) and black (-) wires
Refer to instructions for LED activation steps
I am trying to lock one side of the lock but the
cabling has not been installed – how can I do
this:
Set setting switches to required position (PtO will leave the lock
locked once power has been removed)
The lock can be powered via a micro-USB connector connected to
a power bank, PC or mobile phone charger or it can be powered by
the main connector with a 9 or 12V battery connected to the red
(+) and black (-) wires
•If powering by USB, the setting will only take effect after
30 seconds or if immediate response is required – while
powered, briefly press the LED and mode button and the
lock will change to and remain in the failed state. When
the lock is powered through the main connector, normal
operation will resume
•If powering through the main connector, connect and
remove the green wire from the positive terminal of the
battery
•Ensure power is supplied to the lock for at least 5 seconds
