Product Summary
The Learn Mode Shock Sensor has the followin g three main
functions:
❑ To detect the vibrations made by an intruder trying to
break a wind ow or door.
❑ To detect a window or door opening.
❑ To detect tamper situations, such as an intruder remov-
ing the sensor cover.
Vibrations cause a momentary open circuit in the shock element of the sensor. The circuit closes again when the vibration stops. The sensor microcontroller “sees” the o pen/close
action as a pulse, causing the sensor to transmit an alarm
signal. The sensor has two different detection modes:
❑ Gross Attack - detect a violent blow sufficient in length
to trip sensor.
❑ Pulse Count - detect a sufficient number of less violent
blows (rapping or tapping).
The sensor includes an internal magnetic reed switch that
must be disabled if it is not used.
A cover tamper provides additional security if an intruder
tries to disable or damage the sensor.

Installation Instructions
receive sensor signal transmissions. The sensor is an
RF device and there may be blind or non-operational
locations within the installation. Normally, these can be
overcome by moving the sensor or receiver.
❑ Always mount the shock sensor so that the detector is
on the frame and not on glass, solid, or hollow-core
doors. See Figure 2 for mounting locations.

Installation Guidelines
❑ Learn the sensor before adjusting the shock sensitivity.
The sensor is shipped with the reed switch enabled and
open, and this is how it must be learned.
❑ Before permanently mounting the sensor, test it at the
intended location to make sure that the panel can
❑ Mount the sensor in a location where the structure can
transmit vibrations to the sensor.
❑ The sensor can be mounted on a vertical surface or on a
horizontal (flat) surface.
❑ Make sure the window fits snugly in the frame and
doesn’t move or rattle.
❑ Hold the sensor against the frame to make sure the sen-
sor base fits on the surface area of the frame and
doesn’t extend over the surface edges.
Shock Sensor Orientation
There are two types of shock sensor mounting orientations;
on a vertical surface or on a horizontal surface (sill or
ledge).
On a vertical surface, there are two orientations (see Figure
3).
Note
On a vertical surface, the shock sensor element must
always be oriented with its screw terminals down
writing on the shock elem ent horizontal.

mounting orientation on a vertical surface
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 horizontal vibrations perpendicular to its writing than parallel
(see Figure 4).

Installation
Caution!
You must be free of all static elec t rici t y w he n handling
electronic component s. 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 (see Figure 5).

3. Position the shock element and press it firmly into its
socket (see Figure 7).
4. If using the reed switch, use the two remaining screws
to mount the magnet so that its arrow is aligned with the
arrow on the sensor case (see Figure 7).

Important! You must disable the reed switch 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.
