Motion Sensors for Ladders, Towers and Direction Control

PIRAMID LT is an outdoor Dual Technology motion sensor for protecting ladders and towers. PIRAMID LT features PROTECH’s proprietary Stereo Doppler Microwave Technology combined with Passive Infrared. The sensor is configured so that both technologies must activate simultaneously for a sensor alarm. PIRAMID LT is equipped with a three–position Direction Control Switch that selects the direction of movement required for a sensor alarm.

For protecting ladders and towers the PIRAMID LT is generally mounted at the top of the structure looking downward.

The Direction Control Versions of the PIRAMID XL offer a field adjustable switch to control the detection of a target based on the direction of movement. A three–position digital switch allows the sensor to be set to detect: only approaching targets, only receding targets or both approaching and receding targets.

The detection parameters are set up to detect pedestrians and intruders rather than vehicles.
