Enrolling
To enroll the sensor, set your panel into program mode, refer to your specific alarm panel manual
for details on these menus. When prompted by the panel, trigger the sensor by moving the
magnet in and out of range of the sensor. The panel will beep when you have successfully learned
in a sensor.
Mounting
Included with the contact is double sided tape for the contact and the magnet. For reliable
bonding ensure the surface is clean and dry. Apply the tape to the sensor and then to the desired
location. Apply firm pressure for several seconds. It is not recommended to mount the tape at
temperatures below 50°F, although after 24 hours the bond will hold at low temperatures. The
WST-231 may also be mounted with screws if desired.
One side of the sensor is marked with 3 lines; this indicates the location of the reed switch. The
magnet should be mounted facing this side of the sensor, and it must be no further than 5/8 of an
inch from the sensor. An external contact may also be connected to the WST-231 with the
supplied wiring connector.
Interchangeable covers
The contact comes from the factory assembled with a white cover, but included are optional
brown covers. To change the cover, slide the front cover to disengage it from the sensor then
remove. Replace with the brown cover ensuring the Top (as marked on the inside of the cover)
points away from the battery. You should hear a click when the cover engages and disengages
from the sensor. You do not need to replace the back plastic because once mounted the back is
not visible. To replace the magnet cover you will need to gently pry the white cover off with a flat
head screw driver and snap the brown cover in place.
Replacing the Battery
When the battery is low a signal will be sent to the control panel. To replace the battery:
1. Slide the top cover to disengage it from the sensor, then remove it to reveal the battery.
2. Replace with a CR2032 battery ensuring the + side of the battery faces towards you.
3. Re-attached the cover, ensure the Top (as marked on the inside of the cover) points away
from the battery. You should hear a click when the cover engages properly.
Note: Removing the cover will trigger a zone tamper signal to the control panel
