Protection Technology SDI-77XL-DIR Pyramid Sensor with Directional Control: 90 x 50, ABC Lens

The Direction Control Versions of the PIRAMID XL offer a field adjustable switch to control the direction of a target based on the direction of movement. A three-position digital switch allows the sensor to be set to detect 1) only approaching targets, 2) only receding targets or 3) both approaching and receding targets.

• STEREO DOPPLER MICROWAVE DETECTOR: Two receiving channels with the ability to eliminate vibration and periodically moving objects as sources of false alarms.
• DUAL ELEMENT INFRARED DETECTOR: Ignores normal temperature variations yet is very responsive to rapid infrared changes created by an intruder.
• BALANCED TEMPERATURE COMPENSATION: Stereo Doppler Microwave and Passive Infrared portions automatically adjust detection parameters to compensate for losses in range that occur at elevated temperatures.
• MICROPROCESSOR CONTROLLED: Proprietary integrated circuit design provides enhanced digital signal processing for both microwave and passive infrared technologies.
• STEREO DOPPLER SUPERVISION: A component failure will cause the sensor to lock-in alarm.
• DIRECTION CONTROL SWITCH – A Three-position digital switch that controls the direction of movement required for a sensor alarm. The sensor can be set in one of three modes:
  1. Detect only approaching movement
     
  2. Detect only receding movement
     
  3. Detect both approaching and receding movement.
• DIGITAL RANGE CONTROL: Ten-position digital switch adjusts how far the sensor detects (to it's maximum range).
• DIGITAL SENSITIVITY CONTROL: Ten-position digital switch adjusts the amount of movement required to initiate an alarm condition.
• MASTER LED: Displayed on the face of the unit indicating the alarm relay status.
• ANALYTIC LED'S: Alarm and Environmental Caution LED's for both technologies displayed on the face of the sensor. An internal switch can disable both Master and Analytic LED's.
• WALK-TEST SOUNDER: Optional audible tester to assist in the walk-test and initial sensor setup. The XL-Sounder greatly simplifies the installation as it enables walk-testing and adjustment by a single installer.
• SWIVEL MOUNTING: 180º Horizontal Adjustment, 90º Vertical Adjustment.
• TAMPER-PROOF: Tamper switch with terminal connection.
• ALL SOLID STATE RELAY: User selectable Form C relay output. A Solid State relay is flexible, silent and more reliable than an electromechanical relay.
• METAL RAINTIGHT HOUSING: Rugged, weatherproof housing offers maximum protection against RFI and EMI interference.
• WEATHER SHROUD: Metal hood that routes rain from sensor's face and also provides maximum protection from ice, snow, wind and sun loading.
