Installation
Caution!
You must be free of all static electricity when handling elec-
tronic components. Touch a grounded, bare metal surface
before touching a circuit board or wear a grounded wrist
strap.
1. Insert a slotted screwdriver into the slot at the top end of
the unit and remove the cover by lifting it up (see
Figure 2).
Figure 2. Removing the Cover
2. Using the flathead mounting screws, secure the base to
the mounting surface either vertically or horizontally as
required (see Figure 3).

3. Position the shock element and press it firmly into its
socket.
Note
On a vertical surface, the shock sensor element must
always be oriented with its screw terminals down, or the
writing on the shock element horizontal.

Note
On a horizontal surface (sill or ledge), any orientation is
allowed, but certain sensor element orientations are better
than others. The element is much better at detecting hori-
zontal vibrations perpendicular to its writing than it is parallel
vibrations (see Figure 5).

4. If using the reed switch, use the two remaining screws to
mount the magnet so its arrow is aligned with the arrow
on the sensor case (see Figure 7).

Important!
You must disable the reed switch using the dip
switches on the circuit board if you are not using it. If
the reed switch is enabled but no magnet is installed, the
sensor will be in a continuous alarm state. See the Sensor
Settings section for more information.
5. Install the tamper switch as shown (see Figure 7).
