Protech Technologies 30742204C MIRIS 3100 6.5ft, Double Face 4 Cells, 24-48VDC, includes Heater & Integrated Anti-Climbing Cap

The Protech 30742204C MIRIS 3100 Active Infrared Barrier delivers commercial-grade perimeter protection in a 6.5 ft. (2 m) double face tower configuration with 4 infrared detection cells per direction. Featuring patented 100Hz Dual Interlaced Scanning (D.I.S.) technology, this bi-directional tower integrates both transmitter and receiver functions on two opposing faces - enabling corner protection and 90° perimeter angles from a single tower location.

Alarm contact outputs directly on each tower reduce wiring complexity. The synchronized multiplexed beams support three detection modes: mono-beam, dual adjacent beam (eliminating dead zones), and temporized mono-detection for crawl intrusion at the bottom beam.

Includes an integrated anti-frost thermostat heater for reliable operation from -40°F to +158°F and a built-in anti-climbing cap for tamper protection. With a maximum detection range of 656 ft. (200 m) per tower pair and 24-48VDC power supply with optional 12V battery backup, the MIRIS 3100 Double Face is the ideal for utilities, substations, transportation hubs, and commercial/industrial perimeter security.
