DESCRIPTION
The FM-RCHn-XXXRS is a complete remote control system supplied ready to operate. Installation requires
connections to be made only to the power supply which can be 240Vac or 12Vdc.
Available in options of 1 - 4 channels. It provides 5A rated relays at 240Vac with either momentary or latching
operation. The system incorporates a highly secure ‘code hopping’ transmission protocol to prevent grabbing
and scanning of the data.
The outputs may be programmed to operate in latching or momentary mode. (there is a maximum of two
latching or three momentary outputs). A timed output feature is also available on output four.
The system has a range of up to 200 metres in direct line of sight, and requires minimal installation. The
decoder has an easy learn feature which enables it to learn the ‘signature code’ of individual
transmitter/encoders switches.(These are memorised even if the power is removed).
The decoder may also be used in conjunction with the FM-ECAC auto transmitting encoder. (RS Stock code
226-3398)
The system is supplied ready to operate with the remote transmitter/encoder. The decoder is supplied in an
IP64 rated enclosure.

WARNING
This appliance may be connected to the mains. The unit is design to be a fixed installation which may be
connected to the mains supply. Before removing the cover, ensure that the mains input supply is removed. Any
operation of the product that involves removal of the front cover should only be carried out by a competent
person or qualified electrician.
DATA OUTPUTS
Output 4 has a variable timed output which maybe adjusted from 10secs to 5 minutes. This is controlled by the
adjustable pot RV1.
Outputs 1 & 2 may be configured as momentary or latching operation by link 2 on the FM-DH0-418 decoder
module.
For use as a standard remote Control system Link 1 MUST be fitted.

LEARNING A NEW TRANSMITTER SWITCH
FM-RCH
N
-XXXRS
These decoders are capable of ‘learning’ the transmitter/Encoder signature code, and individual switch
number.
The decoder allocates a specific transmitter/encoder’s switch, against the chosen decoder output. The decoder
has a maximum memory capacity of learning up to eight unique encoder switches. These may be from a single
or many different encoders and be allocated to a single output or a combination of all the outputs on the
decoder.
To learn a new transmitter switch follow these procedures;
1. Firstly determine which switch on the encoder and which output channel on the decoder you wish to allocate
to each other.
2. In order to select the appropriate decoder output channel, the user must step through the outputs until the
desired channel is selected (these may be 1, through 4).
3. Each time the decoders programming switch is briefly pressed and released, the LED will flash a number of
times to indicate which channel is currently selected.
4. If the desired channel is overstepped or missed, simply wait for 5 seconds and the decoder will start from
channel 1 again, or step right through the outputs, and the decoder will automatically return to channel 1.
5. Note that after flashing 4 times to select channel 4, the decoder flashes 9 times. This is normal and is
detailed below in the “Erase memory” section.
6. To enter “Programming mode” the user must hold down the programming switch whilst the desired channel
(indicated by the appropriate number of flashes) is currently selected. After flashing the required number of
flashes, the LED will go out for approx. 4 seconds and then illuminate. The decoder is now in learn mode.
(Keep the programming switch depressed)
7. Depress the transmitter once, LED on the decoder will flash. (PSW is still depressed).
8. Wait for LED to stop flashing.
9. Depress the transmitter again, LED will turn off. (PSW is still depressed).
10. Release the programming switch (PSW).
11. The decoder has now learnt the encoder switch and will now operate the system.
Note: Do not teach the same switch to more than one output of the same decoder!
ERASING THE DECODER’S MEMORY
To completely erase the FM-ECAC signature code form the FM-DH0 decoder’s memory;
1.
Press the FM-DH0 decoder SW briefly. (The LED will flash once).
2.
Press the FM-DH0 decoder SW again briefly. (The LED will flash twice).
3.
Press the FM-DH0 decoder SW again briefly. (The LED will flash three times).
4.
Press the FM-DH0 decoder SW again briefly. (The LED will flash four times).
5.
Press the FM-DH0 decoder SW and hold. (The LED will flash nine times, go out for several seconds
then illuminate again.
6.
The FM-DH0 decoder switch may be released. (When the LED goes out, the FM-DH0 decoder
memory is erased)
SYNCHRONISATION (Hopping Models only)
This equipment requires the transmitter and receiver to be synchronised. If the transmitter has been pressed
more than 50 times outside the range of the receiver, the receiver will loose synchronisation with the
transmitter. To re-synchronise: Press the transmitter key for two seconds within range of the receiver,
Release the key momentarily, and press the key again.
