Description
The FMR-24002 is a crystal controlled two channel receiver, comprising of receiving, decoding and relay-output sections. A specially designed micro-controller is used in the decoder section, which ensures operation for highest reliability.
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 8 Amps.
Connection to the receiver is via a eight-way screw-type terminal block. The receiver can be mounted to a Quick Mount or in a C160 weatherproof case.
Elsema’s ANT27MHz series antennas will give a reliable control range of up to 200 metres, when used with Elsema’s FMT-301, FMT-302 and FMT-304 transmitters.
Different Modes for the Output
Modes are user selectable from the 2-way dipswitch. Dipswitch 1 corresponds to relay channel 1 and dipswitch 2 corresponds to relay channel 2.
| Momentary Mode |
If the dipswitch is “off” the relay will be in momentary mode. |
| Flipflop Mode |
If the dipswitch is “on” the relay will be in flipflop mode. |
| Latching |
If latching is required (Relay stays on until power is removed) the latching link should be inserted and soldered into the two holes to the right of the 2-way dipswitch. This will enable corresponding relays to latch. |
Care must be taken, not to bring a receiver near strong magnetic fields, such as DC-Motors, speakers, magnets for reed switches, transformers etc. as it would magnetise the coils and may cause severe de-tuning.
