The Two Wire Shock Sensor is for use with alarm panels without native support for wired shock sensors or where individual control of each sensor is desired on a sensor loop. The sensor utilises a MEMs device for shock detection and a microprocessor to manage its operation on the loop. Up to 10 sensors can be used on a single loop and the power for operation is derived from the loop power using energy harvesting techniques. The loop detection voltage of the panel must be 5V nominal open circuit and zone operation in single or double EOL (End Of Line) mode. For details on how to use/wire see the installation/operating instructions.
