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.

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 |
