Keri’s line of RF Transmitter the TM-40XNT, offer access and security in a small, sleek, cost effective package. Typically attached using a Key Ring, the transmitters provide a convenient way to grant access to gates and parking barriers while staying safe and dry in a vehicle. The most popular application is for gated residential communities, where residents and employees can use the transmitter buttons to access gates as they approach or to provide convenient access for the disabled. An optional proximity insert provides additional convenience so users can access other secure parts of a facility using proximity readers tied to the same access control system as the gates. The Nema 4 rated enclosure, noise reduction circuitry, adjustable read range, and the ability to remotely mount an antenna virtually guarantee a quick and painless installation. The system is FCC Part 15 and CE approved.
