SDI-77

SKU: SDI-77 $719.00
SDI-77 - PIRAMID Long Range 100 ft. x 15 ft. – DC Power “And Gate”

The "LT" (Ladder and Tower) Version of PIRAMID is an Outdoor Dual Technology Motion sensor specifically designed to protect against intruders climbing up ladders and towers. The PIRAMID LT Version 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. The Direction Control motion detector switch can be set to one of three detection modes:

1) Approach Mode - Sensor detects only approaching targets
2) Recede Mode - Sensor detects only receding targets
3) Both Mode - Sensor detects both approaching and receding targets

For protecting ladders and towers The PIRAMID LT is generally mounted at the top of the structure looking downward. The Direction Control motion detector switch is set in the "Approach" mode so that the sensor detects only approaching targets, i.e. someone climbing up the ladder or structure.

The PIRAMID (Passive InfraRed And Microwave Intruder Detector) combines Stereo Doppler Microwave and PassiveInfrared technologies into an intrusion sensor in which both technologies must activate simultaneously to create a sensor alarm. The Stereo Doppler Microwave portion activates on the movement of the intruder and the Passive Infrared portion activates on the change in infrared radiation caused by the intruder.

The PIRAMID was designed to satisfy high level and medium level security requirements as well as those environmentally difficult applications. Utilizing the unique combination of Stereo Doppler Microwave and Passive Infrared in a Dual Technology sensor not only increases stability but also permits greater detection sensitivity.

The high false alarm rejection attributed to this unique combination enables the detection sensitivity of each technology portion to be dramatically increased to levels far beyond sensitivity levels that would be practical if used as single technology sensors. The result is greater detection sensitivity, greater stability and higher security. PIRAMID is the ultimate in Dual Technology Sensors.

Features

Two receiving channels rather than one and the ability to eliminate vibration and periodically moving objects as sources of false alarms.
Ignores normal temperature variations yet is very responsive to rapid infrared changes created by an intruder.
Proprietary integrated circuit design provides enhanced digital signal processing for both microwave and passive infrared technologies.
Ten-position digital switch adjusts how far the sensor detects (to its maximum range).
Ten-position digital switch adjusts the amount of movement required to initiate an alarm condition.
Stereo Doppler Microwave and Passive Infrared automatically adjust detection parameters to compensate for losses in range that occur at elevated temperatures.
Interchangeable Fresnel Lens Modules offer a tremendous assortment of protection patterns for optimum flexibility.
A component failure will cause the sensor to lock-in alarm.
Master LED Displayed on the face of the unit indicating the alarm relay status.
Alarm and environmental caution LED’s for both Stereo Doppler Microwave and Passive Infrared portions are displayed on the face of the sensor. An internal switch can disable both Master and Analytic LED’s.
User selectable form C relay output.
Rugged and durable and offers maximum protection against RFI and EMI interference.
Multi-directional
FF-3 Fluorescent Filter is a optional plug-in printed circuit board module that can be field installed on the sensor in applications where nearby fluorescent lighting is affecting sensor performance.
The FF-3 Fluorescent Filter is highly recommended in applications where fluorescent lighting will be left on during the protected hours and the lighting fixtures are located in the sensors field of view (within 20 ft.)
