Description
The FMT151 series gives a controlled range of up to 5km. The controlled operation can be any electronic or electrical operated device when used with the FMR151… series of receivers

The channels are activated via screw type terminals onto which the user can connect reed switches, toggle switches, push buttons or any form of normally open (NO) contact. The input should be voltage free contact closure only.

The 151MHz transmitter is suitable for industrial applications where you would have a high level of electrical interference. This transmitter is not affected by man made or electrical interference. This makes FMT151… an ideal choice for use in heavy industrial environment.

Each transmitter channel is individually transmitted to the receiver making it possible to do simultaneous channel transmission. This means that up to 8 different functions can be done at the same time. Each channel can operate any FMR151… series receivers making it possible to transmit each channel to different single channel receivers or to multi channel receivers.

The transmitter uses a specially programmed micro-controller which ensures the highest reliability, low standby current consumption and greater flexibility.

External supply connection and SO239 antenna socket is provided with the transmitter.

Transmitter Modes

| Off Delay 2 – 62 seconds
Transmitter will transmit a 1.5 second transmission burst and then stop for the “off delay” time selected. The “off delay” time is user selectable between 2 to 62 seconds by adjusting trumpet on the transmitter board. If the inputs change during the “off delay” period, the new code will be transmitted immediately.
---|---
| Off Delay 1 – 10 minutes _
_Same as mode 1 except the “off delay” is user selectable between 1 to 10 minutes.
| Continuous Transmission
Transmitter will transmit continuously, if at least one input is activated and supply is connected. A transmission limit of five minutes is used to comply with local radio regulations.
****| 1.5 – 10 seconds one burst transmission
Transmitter will transmit one burst and then go to standby or sleep mode. Adjusting the trumpet will vary the burst length. When the input is changed and supply is connected, transmitter will transmit one new burst of the new code.

Keeping the receiver ON indefinitely
Set the transmitter to transmit every 10 sec while the input is activated (Off-delay on the transmitter) and set the delay on the receiver to more than 30 sec (more than x3). When the transmitter stops transmitting (Input is deactivated) the receiver will wait for 30 sec before turning Off. Every 10sec pulse from the transmitter will keep extending the 30sec delay on the receiver so the relay stays ON.

The times are just examples and can be adjusted. The longer the delay on the receiver, the better it is. It means the receiver should miss multiple signals before turning OFF. This will also mean that when the transmitter stops, the receiver will wait for it’s delay time before turning off.

Make sure to choose the receiver which has the OFF Delay mode.

Coding Instructions
Do not use the factory default code on the 12-way dip switch. Set you own random code. Set the dip switch on the receiver to match the transmitter code. To access the 12-way dip switch, you will need to open the transmitter cover.

Apart from the 12-way dip switch there is an additional 3-way dip switch on the FMT15101E. This 3-way dip switch selects the receiver channel.
If you are using 8 x 1-channel transmitters with a single 8-channel receiver and each transmitter should activate a different channel on the receiver, then the setting of the 3-way dip switch will have to be different on each transmitter (3-way dip switch will give you 8 combinations). See table below.

Operating Frequency
There are 8 selectable frequencies available. This is achieved by setting the 3-way dipswitch. The default setting is for 151.6MHz (All 3 dipswitches “ON”). Following is a table with the Dipswitch settings and the corresponding frequencies.
