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 cor-
rect polarity (see diagram below). Use only the Eveready
Lithium Energizer No. EL123AP, Tekcell or Panasonic
CR123A lithium battery.
WARNING!: Battery may explode if
mistreated. Do not recharge, disas-
semble or dispose 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 Instal-
lation Manual for instruction).
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 screw-
driver between the base wall and the bottom of the cir-
cuit board and pry the circuit board up.
NOTE:
Please refer to the WLS925L-433/WLS935L-433 Installation Instructions for more details.
Door/Window Contact
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.

Connect the device to the contact terminals of the
WLS925L-433 / WLS935L-433.
The input is normally closed and is not supervised.
The wires connecting the external device to the input ter-
minals can be up to 18" (45cm) provided that the resis-
tance of the wire does not exceed 100Ω. The contact and
transmitter must also be in the same room.
Only one contact can be used. If an external contact is
used, do not install the magnet.
Tamper Switches
There is one tamper switch on the WLS925L-433 and
two tamper switches on the WLS935L-433. Removing
the cover on either contact will cause a zone tamper.
Removing the WLS935L-433 from its mounting surface
will also cause cause a zone tamper.
