Abstract

1. An alarm system comprising at least one battery-operated subsidiary station (A) with an alarm (1) and a transmitter (5-8) coupled thereto for wireless signal transmission to a receiver (9) of a main station (B), where the subsidiary station contains a battery-monitoring stage (2) which transmits a signal when it reponds, characterised in that the transmitter (5-8) transmits a continuous signal when the alarm (1) has responded, that the transmitter (5-8) transmits periodic short pulses when the battery-monitoring stage (2) has not responded, and that the main station is mains-operated.
