The SpreadNet model SN930-DOOR Universal/Door Transmitter is a truly versatile wireless RF transmitter.
Using Spread Spectrum technology, the SN930-DOOR provides higher power, lower noise levels, less interference, and longer range than obtainable with most single-frequency RF tranmitters, resulting in increased reliability.
The unit is equipped with two internal reed switches (S2 and S3) mounted on the printed circuit board and a magnet assembly. The transmitter is also equipped with a set of terminals to allow the use of an external device.
