Abstract

An alarm system (40) for an unmanned radio transmitter installation for relaying a stereo radio signal from an associated radio station. The alarm system (40) has one or more sensors (41) to monitor a desired conditions such as the fuel level in a fuel tank for an emergency generator at the installation. Means (43) is provided for stripping off the stereo pilot tone form the radio signal in response to a sensed alarm condition, the transmitter installation then broadcasting a mono radio signal. A tuner (31) provided at the radio station operates a warning lamp (46) upon receiption of the mono radio signal.
