IMPORTANT!: If the
reed switch is not being used; must
disabled. If the reed switch is enabled but no
magnet is installed, the sensor will be in a
continuous alarm state.
Adjusting the Shock Sensor
DIP switches
The following describes the DIP switch functions:
DIP Switches 1 and 2: Adjust the Pulse Count.
DIP Switches 3 and 4: Adjust the sensitivity setting of
Gross Attack detection.
Gross Attack detection.
DIP Switch 5: Enable/disable reed switch.
DIP Switch 6: Not used.
Note: In order for the LED to indicate shock detection while adjusting
the sensitivity, be sure the reed switch is disabled (DIP switch 5
OFF) or that the magnet is lined up with the reed switch if DIP
switch 5 is ON.
OFF) or that the magnet is lined up with the reed switch if DIP
switch 5 is ON.
Gross Attach Adjustment
1. To adjust the sensor for Gross Attack, set DIP switches 1
and 2 to the ON position. This disables the Pulse Count so
that the unit can only be activated by a Gross Attack.
2. 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.
3. Use switches 3 and 4 to adjust the Gross Attack sensitivity
of the sensor (see Table 1).
4. Repeat step 2 each time a sensitivity change has been
made.

Pulse Count Adjustment
1. Set the sensor to the desired Pulse Count (see Table 2
below).
Note: 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.

2. 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.
3. Use switches 1 and 2 to adjust the Pulse Count.
4. Repeat step 2 each time a sensitivity change is made.
Reed Switch Setting
After adjusting the sensor sensitivity, set DIP switch 5 to the
appropriate setting, ON for enabled or OFF for disabled.
