FMR-202
27MHz RECEIVER WITH TWO CHANNELS
The FMR-202 is a crystal controlled two-channel receiver,
comprising of receiving, decoding and relay-output sections.
A specially designed MICRO-PROCESSOR is employed 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, from the transmitter matches the setting of the
10-way code switch on the receiver (up to 1024
combinations), an output is obtained i.e. the relay operates.
This relay provides a clean set of contacts for switching DC
current up to 5 Amps.
The two channels address code switch eleven. While code
switch twelve is addressed with the wire link next to the
receiver code switch. This feature enables the user to operate single channel transmitters on either of
the two channels.
The supply and antenna connections to the receiver are via a three-way screw-type terminal block,
with a separate six-way terminal block for the relay connections.
The receiver can be clipped to a Quick Mount enabling the receiver to be easily mounted against walls,
roof, etc.
As an antenna, a piece of any type of wire, approximately one meter long, will be sufficient for a
reliable control range of up to 180 metres, with our FM-... series transmitters. A longer wire or a
proper 27 MHz CB-Antenna should further improve performance in reception.
The two-way code switch (See below picture) allows individual control of each relays output mode. In
the momentary mode the output relays are only activated while the correct signal is received. In the
flip-flop mode the output relays are toggled with every correct incoming signal. This enables the direct
use for switching on/off lights etc. In flip/flop mode, the relays are off at the initial "power-up".
Latching Feature
Inserting a .4” link into the latching link holes will configure the channels to latching “ON”, when the
correct signal is received. To turn relay “OFF” power to the receiver must be momentary turned
“OFF”.
