Product Summary
The sensor detects the opening/closing of a door
or window. The sensor is typically installed in the
door or window frame and the magnet is installed
in the door or window. When the door or window
is opened (magnet moved away from the sensor),
the sensor transmits an open (TRIP) signal. When
the door or window is closed (magnet aligned
with the sensor), the sensor transmits a close
(RESTORE) signal.
The sensor transmits supervisory signals every 64
minutes (approximately). The sensor is powered
by a 3.0 volt, long-life, lithium battery.
Tools Needed
• electric drill
• 5/8 in. paddle or twist drill bit
• 3/4 in. twist drill bit
• standard slotted screwdriver
• tape measure or ruler
• pencil, pen, or piece of chalk
• RF Sniffer
Installation Guidelines
• Try to keep sensors
Sensor
within 100 feet of the
panel or repeater.
• Avoid mounting a sen-
sor in an area where it
will be exposed to
moisture.
• Avoid mounting a sen-
Magnet
sor where temperatures exceed 120° F
(49 ° C).
• Avoid mounting a sen-

Magnet
sor where temperatures fall below 10° F (-12° C).
• Whenever possible, mount the sensor in the
casing, not in the moving door or window. In
the case of double doors, mount the sensor in
the least used door, with the magnet in the other
door. This is done to avoid excessive jarring
which can reduce battery life.
Document No. 466-2157 Rev. C
• To avoid electrical wiring, mount the sensor in
March 2009
the header (top) of the door or window frame.
WARNING!
Some installations may have electrical wiring running through door or window frames. Use caution
to avoid electrical shocks. To minimize the risk of
electrical shock from concealed wires, mount the
sensor in the top of the door or window frame (see
Figure 2)
Magnet Installation
1. Determine a suitable location for the sensor.
2. Measure and mark where the magnet will be installed in the door or window.
3. Measure the distance between the door or window and the frame header.
4. Drill a 5/8 in. diameter hole 3/4 in. deep into the door or window (see Figure 2).
NOTE:
Countersinking
requires 2 drill bit
sizes: 3/4 in. and 5/8 in.

Door Clearance
Drill 3/4 in. deep
with 5/8 in. bit.
5. Push the magnet into the hole, magnet side first.
6. Measure and mark where the sensor will be installed in the frame.
Sensor Countersink Mounting
To install the sensor in countersunk applications (preferred), drill a 1/8 in. deep starter hole in the frame
with a 3/4 in. twist type drill bit. Finish the hole by
drilling with a 5/8 in. drill bit, until the complete hole
depth measures 3-3/4 in. (see Figure 2).

Sensor Non-Countersink Mounting
1. To install the sensor in non-countersunk applications, there must be at least 1/4 in. of clearance between the door or window and the
frame. Drill a hole with a 5/8 in. drill bit until
the hole depth measures 3-3/4 in. (see Figure
3).
2. Insert sensor into the hole in the frame. Force the metal teeth into the frame by applying firm pressure on the sensor.
3. Close the door or window.
Drill 3-3/4 in. deep
with 5/8 in. bit.
Gap between door/window and
frame must be 1/4 in. or more for
non-countersunk applications.
6. Exit Program mode.
Alternative Add Sensor Method
The following method can be used as an alternative to step 4 in the “Add Sensor to Panel Memory” section.
1. Remove the sensor cover by inserting a screwdriver in the top and rotating counterclockwise.
2. Using a screwdriver press the Add Sensor button located at the top of the circuit board (see
Figure 5).

Adding the Sensor to Panel Memory
Below are general guidelines for adding (learning)
the sensor into panel memory. Refer to your panel
Installation Instructions for complete details.
1. Set the panel to Program mode.
2. Proceed to the LEARN SENSORS menu.
3. Select the appropriate sensor group and sensor number.
4. Insert the blade of a standard screwdriver into
the slot at the top of the sensor. Press in firmly
while slowly rotating the top 1/8 turn counterclockwise, then rotate it back (see Figure 4)

Sensor to Panel Memory
5. Repeat the above steps until all sensors are added (learned) into the panel.

Memory Method
Testing
The following steps describe general guidelines
for testing the sensor. Refer to your panel Installa-
tion Instructions for complete details.
Note
The sensor has a built-in power-saver feature that turns
on automatically when the sensor is tripped more than
once, within a 4-1/4 minute time period.
When the power-saver feature is on, the sensor transmits only half the usual number of data rounds when
tripped. For example, during a dealer sensor test you
normally expect to hear up to 8 data rounds. When the
power-saver feature is on, you may hear only up to 4
data rounds.
To be sure the sensor has acceptable transmitting
range to the panel, leave the sensor undisturbed in the
closed (non-alarm) condition for 5 minutes before tripping it for testing. This gives the sensor enough time to
turn off the power-saver feature so you can get accurate sensor test results.
1. Set the panel to the Dealer Sensor Test mode.
2. Trip the sensor by opening the door or window to verify that it has an acceptable transmitting range with the panel.
3. Listen for interior siren beeps to indicate how many rounds the panel receives from the sensor. You should hear 6 to 8 beeps.
• Use an RF Sniffer to help diagnose faulty sen-
sors.
