IntroductIon
The 100-527 Ness Universal Transmitter is a 9V
battery operated transmitter with 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 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 onboard reed switch allows for standalone
door or window protection without using the
external input. (The Ness 100-662 RR1 miniature
radio reed switch can also be used for this
purpose).
The Ness Universal transmitter also features
radio encryption and supervision for total radio
security.
