Essential Info

The TOWER®-12AM is an industrial grade 3 dual-technology intrusion detector with anti-masking. Featuring extremely high coverage of 25mx 30m (82ft x 100ft) / 90o, it is designed for large sites with medium to high security requirements and for harsh security environments with a high likelihood of false alarms. Warehouses and other large facilities, where temperature swings are common due to the absence of air conditioning and where rodents are commonly found, are typically exposed to higher than usual rates of false alarm-causing electrical and environmental interference, making them ideal sites for TOWER-12AM detectors.

Leveraging several patented, breakthrough technologies, including Visonic's innovative Obsidian Black Mirror and V-Slot® window technologies, the TOWER-12AM detector provides market-leading detection sensitivity, and unprecedented anti -vandalism and anti-masking capabilities. The combination of those two unique technologies with dual PIR/MW technology ensures maximum immunity to false alarms even in harsh security environments where the risk of false alarms is higher than in most sites.

The TOWER-12AM is designed and constructed completely differently to other motion detectors, and is relatively small in size, yet it provides exceptional performance that outstrips industry norms. It combines an extremely large coverage area, unparalleled catch performance, easy installation, and assured, long-lasting reliability.

With its breakthrough technologies, high-performing anti-false alarm capabilities and innovative design, the TOWER-12AM offers the most advanced dual technology mirror detector available.
