Low Battery Warning
When a valid proximity credential is presented to the lock and the batteries are weak, a steady tone will sound for the
duration of the Pass Time ("Pass Time" is the duration the lock remains unlocked after access is granted). Discard
the weak batteries and replace with four (4) AA-size 1.5 volt alkaline batteries. Always replace weak batteries as
soon as possible.
Battery Replacement
The batteries are located within the
Control Unit
(each type pictured below), therefore the battery replacement steps
will vary with the design. Avoid pressing
the "
Program / Passage
" button during this procedure (see diagrams on page 8)
.
To replace batteries in the
Mortised Networx Control Unit
:
1. Remove the two 8-32 x 1/4" Phillips Flat-Head screws that secure the flush
Finishing Plate
that covers the
Mor-
tised Networx Control Unit
. Put screws aside in a safe place.
2. The
Finishing Plate
is connected to the internal PC board with a wire (take note of how the
wire was placed under the PC board at the factory). Gently lift and move the
Finishing
Plate
to the side.
3. Pull out the battery connector wires and disconnect the plugs.
4. Taking note of its original orientation, pull out the battery pack.
5. Remove the screw securing the battery pack top cover, then lift the top cover. Remove all
weak batteries and replace with fresh batteries, observing polarity. NEVER mix weak bat-
teries with fresh batteries.
6. Replace the battery pack top cover and secure with the screw. Insert the battery pack in
the same orientation as its removal in step 4.
7. Connect the battery connector plug. If you
do not
hear 3 beeps when power is re-applied,
all programming and settings have been retained, and the lock will be ready for use. If you
do
hear 3 beeps when power is re-applied, wait 15 seconds for the LED to flash red 7
times and 7 beeps will sound (the clock will need to be reset using DL-Windows).
8. Gently push the battery wires (and any other loose wires) back into the
Control Unit
.
9. Return the
Finishing Plate
to its original location and secure with the two 8-32 x 1/4" Phillips Flat-Head screws.
To replace batteries in the
Surface-Mounted Networx Control Unit
:
1. Using the supplied Allen key, remove the mounting screw (#6-32 Allen Head countersunk U-
cut Dog Point screw, part #SC681, shown at right). Put screw aside in a safe place.
2. Lift the bottom of the
Surface-Mounted Networx Control Unit
and unhook the top.
Gently lift from the door surface; do not pull wires. It is OK to let the unit "hang" from
the door.
3. With two fingers, firmly grasp the battery wires connected to the white plug. Pull the
wires until the plug releases from the white female socket. It is OK to use some force in this
step.
Do not remove the battery pack yet
.
4. Taking note of its original orientation (top cover screws facing "down"), remove the battery
pack.
5. Remove both screws securing the battery pack top cover, then lift the top cover. Remove all
weak batteries and replace with fresh batteries, observing polarity. NEVER mix weak batteries
with fresh batteries.
6. Replace the battery pack top cover and secure with two screws. Insert the battery pack in the same orientation
as its removal in step 5.
7. Insert the white battery plug into the white socket and press firmly until secure. If you
do not
hear 3 beeps when
power is re-applied, all programming and settings have been retained, and the lock will be ready for use. If you
do
hear 3 beeps when power is re-applied, wait 15 seconds for the LED to flash red 7 times and 7 beeps will
sound (the clock will need to be reset using DL-Windows).
8. Ensure all wires are pushed back into the door to avoid pinching wires. Carefully hook the top of the
Surface-
Mounted Networx Control Unit
into the top of the
Control Unit Mounting Plate
(see installation instruc-
tions if necessary) and press the bottom until flush with the door surface. Replace the #6-32 Allen Head coun-
tersunk U-cut Dog Point screw (part #SC681 as shown above) at the bottom of the
Surface-Mounted Networx
Control Unit
and tighten securely. Replace all hardware removed as required.
