DIRECTION CONTROL SENSOR FOR PROTECTING LADDERS AND TOWERS

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 sensor can be field adjusted to 1) detect only approaching movement 2) detect only receding movement or 3) detect both approaching and receding movement. The PIRAMID LT sensor is generally mounted at the top of the ladder/tower/structure looking downward..

EXPLOSION-PROOF INTRUSION SENSOR

SDI-77XL2-EX and SDI-77XL2-EX-EU sensors were developed to protect hazardous locations due to the presence of flammable gasses or vapors, combustible dusts or easily ignitable fibers or flyings. The EX sensor is suitable for applications in North America under the NEC classifications:
Class I, Div. 1 & 2, Groups C, D
Class II, Div. 1 & 2, Groups E, F, G
Class III, NEMA 7CD, 9EFG

The EX-EU sensor is suitable for applications in Europe under the IEC/ATEX classifications:

Zones 1 &2 and 21-22
According to CENELEC:
-Conforming to ATEX Directive 94/9 EC and standards EN 50014-18
EC 0081 II 2 G for Gas EEx d II B T6
EC 0081 II 2 D-T = +85 degrees C for dust
According to IEC: - DIPA 21 Ta + + 85 degrees C

The SDI-77XL2-EX and SDI-77XL2-EX-EU sensors utilize “Stereo Doppler” Microwave technology for unequalled false-alarm-free performance. The EX sensors are microprocessor controlled with enhanced digital signal processing and provides a protection pattern coverage of 100 ft. x 40 ft.

PROTECH’s NEW PIRAMID XL2 Outdoor Dual Technology Sensors WITH ENHANCED Bird and Animal Immunity

PROTECH/Protection Technologies, Inc. is a leading intrusion sensor manufacturer in the USA of outdoor intrusion sensors. All PROTECH sensors are based on a unique microwave sensor design termed “Stereo Doppler”. This proprietary microwave design enables PROTECH sensors to determine the precise movement in centimeters a target has to move to activate a sensor alarm. This movement parameter is field adjustable with an internal Sensitivity Control Switch.

The PIRAMID XL2 sensor’s most important attribute is its unique false-alarm-free performance. Since 1993 PROTECH has been constantly improving and perfecting the PIRAMID outdoor sensor. Our third generation PIRAMID XL2 Series offers enhanced bird immunity and a new unbelievably effective digital signal processing circuit. Rain, snow, sleet, fog, ice, wind, high temperature or low temperature does not affect the PIRAMID XL2 sensors. In addition, moving vegetation, blowing debris, swinging signs, vibration or randomly moving objects does not affect the PIRAMID XL2 sensors.

The PIRAMID sensors are not only utilized as a triggering device for remote video monitoring but are also used in security applications due to the unequalled reliability and false-alarm-free performance of the sensor. In fact, the PIRAMID XL2 sensors should be considered for any outdoor area where there is a threat of vandalism, terrorism, sabotage or theft.
