Abstract

The alarm system is designed e.g. for maintenance workers who may be out of sight from the maintenance team. Each ferion (A) carries a short range small radio transmitter (5). The range (R) of transmission being of the order of 10-15 metres. The transmitter is designed to be clipped to clothes of the ferion and is designed to be triggered when it is placed in a horizontal position. A mercury switch is used actuate the transmitter. The system also uses a number of radio receivers (4) fitted with flashing lamps. These receivers are fitted to a ceiling or other height position through the place where maintenance is being carried out. At least one of them is within the range of the signal emitted from the transmitter.
