International Shock Sensor Installation
Instructions
Product summary
The International Shock Sensor (RF620I4, RF620I4B,
RF620I4-N, and RF620I4B-N ) has the following 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 removing
the sensor cover.
Figure 1: Shock sensor
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.
A cover tamper provides additional security if an intruder tries
to disable or damage the sensor.
