Abstract

The intruder alarm system has several detectors communicating with a central device (1). This evaluates the alarm condition from the signals provided from the detectors, as transmitted radio signals. The transmitted signals are provided via two different signal frequencies, to include a handshaking signal arrangement. A test transmitter and receiver within the central device use a test signal with at least one of these frequencies for checking the alarm signal transmission channel.
