The Seco-Larm Enforcer 4-Button RF Transmitter, 15-Channel comes in two available variations to fit your individual needs. Pair the transmitter with any 315MHz Seco-Larm receiver to wirelessly operate applications, such as home automation functions, garage door openers, house lights, alarm control panels, motorized gates, lifts, etc. Extreme Durability Even with a slim-line design, these transmitters are made to last. Rubber buttons eliminate damage caused by electrostatic discharge and help make the transmitter water resistant. Gold-plated battery clips and contact points also extend the life of the transmitter. CODEBUMP Technology With Seco-Larm’s CODEBUMP technology, so-called codegrabbers and scanners are rendered obsolete because the RF code changes every time the transmitter button is pressed. In addition, with over 18 quintillion (1.8 x 1,019) codes, the chances of ever repeating a code are virtually nonexistent. Seco-Larm’s CODEBUMP transmitters and receivers are perfect for controlling garage and gate openers, car alarms, home alarms and more.
