SDI-76XL-DIR-LT - PIRAMID “LT” Ladder and Tower Dual Technology Sensor – Wide Angle

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..

Features:

• Two receiving channels with 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.
• Stereo Doppler Microwave and Passive Infrared portions automatically adjust detection parameters to compensate for losses in range that occur at elevated temperatures.
• A component failure will cause the sensor to lock -in alarm.
• 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.
• Three-position digital switch that controls the direction of movement required for a sensor alarm. The sensor can be set in one of the three modes
• Displayed on the face of the unit indicating the alarm relay status.
• Alarm and environmental caution LED's for both technologies are displayed on the face of the sensor. An internal switch can disable both Master and Analytic LED's.
• Optional audible tester to assist in walk-test and initial sensor set-up. The XL-Sounder greatly simplifies the installation as it enables walk-testing and adjustment by a single installer.
• Multi-directional
• Tamper switch with terminal connection.
• User selectable form C relay output. A solid State relay is flexible, silent and more reliable than an electromechanical relay.
• Rugged, weather-proof housing offers maximum protection against RFI and EMI interference.
• Metal hood that routes rain away from sensor's face and provides maximum protection from ice, snow, wind and sun loading.

MOUNTING ON LADDERS
For mounting on a ladder, it is recommended that the PIRAMID LT version be ordered with one of PROTECH's Ladder Mounting Brackets -PH-6 or PH-6JB. These specially designed brackets will reduce installation time and offer maximum flexibility when mounting to both caged and non-caged ladders.

SPECIAL DISCRIMINATION CIRCUITRY
The PIRAMID LT is configure with enhanced immunity to fast moving targets so that flying birds and moving vehicles are ignored by the sensor. The Sensitivity Control Switch precisely controls the amount of movement required to initiate an alarm. The benefit of controlling the amount of motion required for an alarm is that in lower sensitivity settings the PIRAMID LT can ignore movement on the ground such as animals, pedestrians, small vehicles, etc.
