The “LT” (Ladder and Tower) version of PIRAMID is a dual-technology sensor specifically designed to protect against climbing up ladders and towers. A three-position digital switch controls the direction of movement required for a sensor alarm. The PIRAMID XL-LT sensor is generally mounted at the top of the ladder/tower/structure looking downward. In this configuration the sensor is field adjusted to detect only an approaching target (someone climbing up the ladder or structure). PROTECH/Protection Technologies Inc.
