Remove Cover
At the notched location on the cover, insert the flat
blade of a small screwdriver between the base and the
cover and twist the screwdriver to pop the cover off.
Install Battery
Use care when installing the battery and observe the
correct polarity (see diagram below). Please refer to the
WLS925L-433 Installation Sheet for more information
on battery installation.
NOTE: Battery
replacement must
only be done by a
qualified techni-
cian.
WARNING!:
Battery may explode if mistreated.
Do not recharge, disassemble or dis-
pose of in fire.
L
ocate Transmitter
Locate where the transmitter is to
be mounted. Perform the Module
Placement Test to ensure that the
selected location is in range of
the wireless receiver (see receiver
Installation Manual
for instruc-
tion).
Determine where the magnet will
be placed. In order to activate the reed switch, the
magnet must line up with the end of the transmitter.
Remove Circuit Board
Before mounting the unit, remove the circuit board. At
the notched location on the base which is on the same
side as the reed switch, insert the blade of a small
screwdriver between the base wall and the bottom of
the circuit board and pry the circuit board up.
NOTE: Do not touch the coils on the circuit board
as this may damage the unit.
Mount Transmitter and Magnet
Mount the backplate of the transmitter using the
screws provided and replace the circuit board. The
head of the screw must be below the circuit board so
that the sensor is not shorted out. Use flat-headed
screws only.
Mount the magnet no more than ¼" (6.4mm) from the
transmitter. Use the spacers provided . Once the unit and
magnet are mounted, open and close the window/door
to ensure that none of the parts interfere with this move-
ment. Only one magnet can be used per transmitter.
Using External Contacts
The external contact
terminals can be used
to connect external
contacts or other
switches/devices to the
universal transmitter.
Install the additional
device as per the man-
ufacturer’s instruction. Connect the device to the con-
tact terminals of the WLS925L-433.
The input is normally closed and is not supervised.
The wires connecting the external device to the input
terminals can be up to 18” (45cm) provided that the
resistance of the wire does not exceed 100
Ω
.
Only one contact can be used. If an external contact is
used, do not install the magnet.
Tamper Switch
There is one tamper switch on the WLS925L-433
board. Removing the cover will cause a zone tamper.
Enrolling a WLS925L-433
On the back of the door contact housing, there will be
two serial numbers, a five digit and six digit. Enroll the
six digit number.
