Ness RR2 100-527 7.8cm Universal 9V Transmitter w/ On-Board Reed Switch White

The 100-527 Ness Universal Transmitter is a 9V battery operated transmitter with the onboard reed switch, an external input and vibration analyser.

The external input can be used to take inputs from normally closed reed switches or emergency buttons. This allows the connection of any type of N.C. switch or button to trigger an alarm signal. The external input can also be used to connect Nessensor vibration sensors for completely wireless vibration sensing. The onboard vibration analyser can be easily adjusted for sensitivity. The onboarded switch allows for standalone door or window protection without using the external input.
