Description
This 2-channel remote control transmitter is used for remote control applications where channel 1 is for a main entry and channel 2 is for a private entry ( Dual Access). When channel 1 (Main Entry) is pressed, code switch 1 to 4 is transmitted as is on the code switch and 5 to 12 is transmitted as OFF regardless to the code switch settings. When channel 2 (Private) is pressed, code switch 1 to 12 is transmitted as is on the code switch. This enables the user to have channel 1 (Main Entry) as a common code and up to 256 different, channel 2 codes. An application would be a large home unit where there is a Main Entry (Channel 1) and up to 256 private garages (Channel 2) within the home unit.
Operating Distance
An operating distance (in conjunction with our FMR-.. series receivers) of 200 metres is possible.
The operating distance depends upon the receiver antenna and location. An independent test revealed the following ranges:
Range (m) |
Receiver Antenna |
Receiver Type |
Up to 50 |
300mm wire |
FMR-… series |
Up to 100 |
ANT27M |
FMR-… series |
Range tests were done in an open area test site with line-of-sight operation and the receiver antenna wire was fixed vertically, away from any metal objects.
