Napco GEM-TRANS2 2-Point Window/Door Transmitter for Napco System

Protect entry points with confident, professional monitoring using the Napco Security Technologies GEM-TRANS2 2-point window/door magnetic contact transmitter. Built for GEM-series wireless security systems, this transmitter provides reliable, two-input sensing—use the internal reed for a conventional magnet-mounted door/window sensor and add one or two normally-closed external contacts for expanded coverage or auxiliary devices. Its wireless connectivity simplifies deployment across commercial, industrial, institutional, or residential sites, reducing wiring time and installation cost.

Technicians and facility managers benefit from a compact, low-profile design that mounts reversibly for left- or right-handed applications, while the 3V lithium battery delivers up to 5 years of service life. Low-battery status is clearly reported at the keypad by zone and transmitter number, helping you stay on top of maintenance and avoid unwanted false alarms. Ideal for access control, intrusion detection, and perimeter monitoring, the GEM-TRANS2 blends discreet aesthetics with dependable alarm performance. Add the GEM-TRANS2 to your next security or surveillance deployment for seamless, low-maintenance door/window monitoring.
