The Protech 30742206C MIRIS 3100 Double Face 6-Cell Infrared Barrier delivers comprehensive perimeter protection with enhanced detection density across two opposing faces from a single 6.5 ft. (2 m) tower. Featuring 6 infrared cells per direction, this configuration provides tighter beam spacing for detecting smaller intrusion profiles and more precise alarm triggering - ideal for corner protection, 90° perimeter angles, and bi-directional coverage applications. With a maximum detection range of 656 feet (200 m), multiplexed cell management through a 4-channel optical link, and four independent alarm outputs (Intrusion, Disqualification, Tamper, Anti-climbing), this barrier integrates seamlessly with existing security management systems via dry contact relays. The integrated anti-frost thermostat heater and anti-climbing cap ensure reliable year-round operation in extreme climates from -40°F to +158°F, while built-in audible and visual alignment aids simplify installation. Powered by 24/48 VDC with optional 12 VDC battery backup, the MIRIS 3100 DF 6-Cell is the professional choice for utilities, substations, transportation hubs, and commercial/industrial perimeter security.
