ELSEMA FMR15102240 2 Channel FMR Receiver with Relay Outputs
Product Usage Instructions
Power Connection:
Connect the receiver directly to a mains supply of either 110VAC or 240VAC.
Programming Transmitters:
Select one of the 8 narrow band frequencies available and program an unlimited number of transmitters to the receiver. Ensure the transmitter code matches the receiver’s unique 12-bit code set by the dip switches.
Relay Output Modes:
Set the relay output mode using the 2-way DIP switch:
- Momentary: Output is active while the transmitter button is pressed.
- Latching: Output remains active until the next press of the transmitter button.
- Delayed OFF: Output remains active for a set duration.
- Security: Output remains active until power to the receiver is removed.
Signal Strength Indicator:
The green signal strength LEDs on the board indicate the level of the received signal. Refer to the provided table for signal strength interpretation.
Noise Strength Indicator:
If more than 2 LEDs are on without a valid transmission, it indicates noise on the selected frequency. Change the dip switch settings to select a different frequency as per the provided table.

Description
This receiver can be connected directly to the mains supply, 110VAC or 240VAC. The relay output is rated at 8 amps at 240VAC. The relay mode can be set to momentary, latching, security latching or adjustable timed Off delays.
The user can select 8 different narrow band frequencies and program unlimited number of transmitters to the receiver. With the narrow band FM 151MHz signal from the transmitter a line of sight operating range of 5000 metres is possible. The receiver uses a crystal oscillator circuit that ensures high frequency stability allowing optimal performance in the receiving range.
Connecting wires to the receiver has been made easier by the pluggable type terminal block. On board LED indicates when power is connected and the relay is being activated.
The receiver comes with a Quick Mount or in a weatherproof case with an IP66 rating.
Available with Options
Different Modes for the Output
2-Way DIP Switch Mode Settings
The output relay will respond in the following manner when receiving the correct signal from a transmitter
- Momentary – Output is active for as long as the transmitter button is pressed. This is a standard mode on most automatic gates or garage door openers.
- Latching – Output remains active until next press of the transmitter button.Similar to switching “on” and “off” a light.
- Delayed OFF – Output remains active for the duration of the time set by the trim pot.
- Security Latching- Output remains active until power to the receiver is removed. Similar to security alarms and fire alarms.
Coding
The 12 way dip switch on the receiver sets the 12 bit unique code for the system. This has to match the transmitter. Do not use the factory default code.
Apart from the 12 way dip switch there will be an additional dip switch depending upon the receiver type:
- Two channel receiver will have a 2 way dip switch.
This DIP switch on the right side of the 12 way dip switch denotes the channel. See table below.
FMR15102
2-Way DIP Switch & 2 Relay Output
| SW13 | SW14 | Relay 1 | Relay 2 | |
| OFF | OFF | Ch1 | Ch2 | |
| OFF | ON | Ch3 | Ch4 | |
| ON | OFF | Ch5 | Ch6 | |
| ON | ON | Ch7 | Ch8 |
Signal Strength Indicator
The 151MHz receivers have green signal strength LED’s on the board. The table below indicates the level of the valid transmitted signal.
| 6 LED’s on | -70dBm | Very Strong signal | Very Reliable operating conditions |
| 5 LED’s on | -75dBm | Very Strong signal | Very Reliable operating conditions |
| 4 LED’s on | -80dBm | Very Strong signal | Very Reliable operating conditions |
| 3 LED’s on | -90dBm | Strong signal | Very Reliable operating conditions |
| 2 LED on | -100dBm | Good signal | Reliable operating conditions |
Noise Strength Indicator
If more than 2 led is “ON” without a valid transmission, this indicates that there is noise on the frequency selected. Change the 3-way dipswitch on the receiver module to select a different frequency. Following is a table with the Dipswitch settings and the corresponding frequencies.
| Frequency | 1 | 2 | 3 |
| 151.600 MHz | On | On | On |
| 152.375 MHz | Off | On | On |
| 151.775 MHz | On | Off | On |
| 151.400 MHz | Off | Off | On |
| 151.175MHz | On | On | Off |
| 151.025 MHz | Off | On | Off |
| 150.900 MHz | On | Off | Off |
| 150.825 MHz | Off | Off | Off |
