General Description
The Slim Line Door/Window Sensor (STWS-DWS-
SLIM) is a door/window sensor developed for use with
the ST security systems. The sensor achieves enhanced
wireless reliability using unique duplex narrow band
frequency diversity, which transmits and receives radio
signals on two separate frequencies.
Additional Information:
Powered by two AAA alkaline batteries, which can
provide power for up to 5 years.
Each transmitter has a unique factory-programmed
code that distinguishes itself to the receiver.
Includes a built-in reed switch that closes if the
magnet is within 1/2” (12mm) of the sensor case.

Installation
Select a sensor location. Avoid mounting the sensor
near the floor. For door mounts, mount the magnet
to the door and the sensor to the door frame.
Remove the sensor cover. Press the plastic tabs to
release the cover from the mounting base.
Mount the sensor base to the door or window frame.
Use included screws to affix the mounting base,
observing alignment marks shown in Fig 1.
Remove the magnet from its base by inserting a
small screw driver into the slot at the end of the
magnet cover. Push in and twist to remove the base.
Mount the magnet base within 1/2” of the sensor base.
Snap the sensor and magnet onto their mounting
bases. If the sensor has not been enrolled, proceed
to the programming procedure before mounting the
sensor on the base.
Note: It is undesirable to mount the sensor or magnet on a metal surface.
If mounting on metal is unavoidable, use spacers (available from Sequel
Technologies) to reduce transmission problems.
Programming
To enroll a DWS into system memory:
Enter program mode (NEXT + NEXT + NEXT +
