Description

The FMR-212 is a crystal controlled single channel receiver, comprising of receiving, decoding and relay-output sections. A specially designed micro-controller is used in the decoder section, which ensures operation at low supply voltage, highest reliability, associated with very low power drain.

The receiver works on a digitally encoded 27 MHz frequency modulated (FM) signal. It may be used in applications such as the remote control of garage doors, gates, lights, alarms or in any other new or existing installations where the use of conventional wiring is difficult or impossible to accomplish.

If the code of the input signal (from a transmitter) matches the setting of the coding switch on the receiver (up to 4096 combinations), an output is obtained i.e. the relay operates. This relay provides a clean set of contacts for switching AC/DC current up to 5 Amps.

Connection to the receiver is via a six-way screw-type terminal block. The receiver can be mounted to a Quick Mount or in a black UBB case.

A proper 27 MHz CB-Antenna will give a reliable control range of up to 200 metres, when used with Elsema’s FMT-301, FMT-302, FMT-304 transmitters. If a CB-Antenna is used, the shield of the cable must be connected to the "Sh terminal".

A push Button (designated as "TEST") is provided for relay output testing.

In the momentary mode (MOM) the relay is only activated while the correct signal is received. When changing the slide switch from "MOM" to "FF” (flip/flop mode) the output relay is toggled with every correct incoming signal. This enables the direct use for switching on/off lights etc.

If a "latching-on" output is required, for example receiver is used together with a "Panic Button", two wire links are to be fitted and the switch to be ON, as shown below. In such a case the relay can only be reset again by momentarily interrupting the supply.
