Product Summary
The Learn Mode Shock Sensor has the following three main
functions:
• To detect the vibrations made by an intruder trying to
break a window or door.
• To detect a window or door opening.
• To detect tamper situations, such as an intruder remov-
ing the sensor cover or the sensor from the wall.
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 open/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.
Extend the battery life of the sensor by adding a second 3volt lithium battery.

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
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 the glass. See Figure 2 for mounting locations.
• 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.

Installation
Caution!
You must be free of all static electricity when handling electronic 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).

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 horizontal vibrations perpendicular to its writing than it is parallel
vibrations (see Figure 5).

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.

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.

Setting the Detection Mode
The shock sensor has two detection modes:
• Gross Attack - detects a violent blow sufficient in length
to trip sensor.
• Pulse Count - detects a sufficient number of less violent
blows (rapping or tapping).
Pulse Count signals are counted at 1-second intervals
and stored in a 30-second digital memory. These small
signals can detect an intruder gently prying open a window or door frame.
To set the shock sensor detection modes:
1. Hold in the tamper spring. Continue to hold in while moving the DIP switches to their desired settings.
2. Set the DIP switches to the desired pulse count (see
Table 1). The LED will start blinking once a DIP switch is
moved.
Table 1: Pulse Count Adjustment
DIP Switch 1 DIP Switch 2
OFF OFF 4
ON OFF 6
OFF ON 8
ON ON Disabled
3. Set the DIP Switches to the desired Gross Attack sensitivity (See Table 2).
Table 2: Gross Attack Sensitivity Settings
DIP Switch 3 DIP Switch 4 Sensitivity
OFF OFF 1 (most sensitive)
ON OFF 2
OFF ON 3
ON ON 4 (least sensitive)
4. Release the tamper spring. The LED will flash quickly 3
times to indicate the settings have been programmed.
5. Repeat steps 1-4 each time you make a sensitivity
change. It may then be necessary to reset the DIP
switches to their proper device settings (See Sensor Settings).
Testing the Detection Modes
To test the Pulse Count setting:
Generate small shocks on the mounting structure. Each
•
time a shock is detected, a pulse is registered in memory
and the LED will blink for one second. If the programmed
pulse count is reached within the most recent 30 seconds, the alarm will trip and the LED will light for approximately 4 seconds. If the alarm trips for any reason, the
stored pulses are cancelled.
30-second Pulse
Count
To test the Gross Attack setting:
Apply high level shocks to the mounting structure, using
•
the LED as a guide to when the alarm trips (LED on for 4
seconds).
The LED will blink for 1 second every time the sensor
detects a pulse. A shock that is severe enough to cause
an alarm will cause the LED to light for approximately 4
seconds.
Sensor Settings
After programming the Detection Mode, the DIP switches
are used to set up the sensors use of the reed switches
and/or external contacts. If the external contact is not used
the 4.7 k Ohm EOL resistor must be installed across the terminals of the external switch block.
With the tamper spring in the up position, set the DIP
switches to the desired settings (See Table 3).
Important!
DO NOT remove the reed switches from the circuit board!
The Shock Sensor will not function properly. If you don’t
need to use the reed switches, disable them with the DIP
switches as described in Table 3.

Battery Replacement
When the system indicates that the sensor has a low battery, remove the old battery and install a new battery (Duracell DL123A or a Sanyo CR123A) into the battery holder,
observing proper polarity.
Caution!
Replace only with a Duracell DL123A battery or a Sanyo
CR123A battery. Observe polarity when installing a new
battery. Installing the battery backwards may cause damage
to the sensor.
Dispose of used batteries according to the manufacturer’s
instructions and/or local government authorities.
