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 an 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 meters 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 have been made easier by the pluggable type terminal block. An 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.

Different Modes for the Output
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 |
 | Latching: Relay alternates at every correct incoming signal |
 | Delayed Off 1: Relay on, but delayed off for 1-10 seconds, adjustable 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 |
 | “Security latching On”: Relay will energize until supply to the 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 |
 | “Instant OFF ” Same is “Delayed Off ” except relay will switch “OFF” as soon as the transmitter input is deactivated |
 | Test: Relay is energized, for test purposes only |
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:
- The 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 the table below.

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 Ver | Very Reliable operating conditions |
| 3 LED’s on | -90dBm | Strong signal Ver | Very Reliable operating conditions |
| 2 LED on | -100dBm | Good signal Re | 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 |
