The ENFORCER RF receivers feature four or five programmable relay output modes (depending on model). Those modes include: four-second momentary, one-second momentary, toggle (on/off), validity, and latch. They operate at 11~24 VAC/VDC, with ranges up to 500 ft. RF receivers are used to control garage doors, gates, house lights, alarm panels or other devices via a remote. LED indicates RF reception, learn mode entered, transmitter learned, memory cleared, and relay output mode. The device can learn up to 15 transmitter button codes. Because the receivers are equipped with push button programming, there is no need to cut jumpers.
