Description

FMR15101 can be used in noisy environment and is least affected by electrical interference. This makes FMR15101an ideal choice for use in heavy industrial environment.

Coding
The 12 way dip switch on the receiver sets the 12 bit unique code for the system.  This has to be matched to that on the transmitter.
Apart from the 12 way dip switch there will be an additional dip switch depending upon the receiver type:

  • Single channel receiver will have a 3 way dip switch.

This DIP switch on the right side of the 12 way dip switch denotes the channel.   See table below.

Generally to use a 1 channel Tx to 1 channel Rx match all the 15 dip switch (12way + 3way just on the right side of the 12 way).

To use a multi channel Tx to control a number of (up to 8) Rx, refer to the table below for the switch setting.

Different Modes for the Output

Modes are user selectable from the 4-way dip switch, shown below.

4-Way DIP Switch Mode Settings
The output relay will respond in the following manner when receiving the correct signal from a transmitter
"Momentary": Relay on, only while correct signal is received
"Flip-Flop": Relay alternates at every correct incoming signal
"Delayed Off 1": Relay on, but delayed off for 1-10 seconds, adjestable by trimpot
"Delayed Off 2": Relay on, but delayed off for 10-300 seconds, adjustable by trimpot
"Pulsing": Relay will pulse at 1Hz for 10-300 seconds, adjustable by trimpot
"Latching On": Relay will energize until supply to receiver is momentarily interrupted
"On-Off": This mode requires a 2-channel Tx.
Channel 1 will always energize the relay
Channel 2 will always de-energize the relay
"Custom": This mode is reserved for specific customers requirements
"Test": Relay is energized, for test purpose only
