2) Remove the sensor cover by squeezing the cover
ends firmly to release the tab on the cover from
the slot on the sensor base.
3) Remove the circuit board from the sensor base by
pulling back the plastic tab and lifting the battery
to release the circuit board.
4) Remove the unused reed switch, clipping the
leads as close to the board as possible (see Figure
2.)

5) Mount the sensor base with screws or brads. Use
spacers to compensate for metal surfaces or
height variations.
6) Remove the magnet from its base. Mount the
magnet base no more than 3/8 inches away from
the sensor base (see Figure 3). Replace magnet
cover.

NOTE:
Mount the magnet so it won't interfere with door
or window openings. Do not use two-sided tape.
7) Reattach the circuit board to the sensor base.
8) Reattach the sensor cover to the sensor base.
Connecting External Switches
Door/window sensors can be connected to either nor-
mally open (close on alarm) or normally closed (open
on alarm) external switches. Wire multiple, normally
closed switches in series. Wire multiple, normally
open switches in parallel.
Do not attempt to use the built-in reed switches and an
external switch on the same door/window sensor. For
high security installations, always remove both reed
switches when connecting an external switch to the
sensor terminals.
Materials Needed
Hermetically sealed external switches (sealed
reed switch) that supply a minimum 250-milli-
second open or closure on alarm.
Stranded 22-gauge wire.
