A RADIO-OPERATED alarm system which dispenses with conventional hard wiring has been announced by Arma Systems, of 6 Cale Street, London, SW3 3QU.
The system can be applied to either freight and passenger vehicles or to industrial premises.
For transport use a receiver, coupled to a noise-emitting device (ie a howler) is controlled by a hand-held panic button which is completely wireless.
If the driver is attacked he simply presses the panic button which emits a signal to the receiver, setting off the alarm.
The range of the panic button is up to 60m (200 feet) from. the receiver.
For on-site protection of industrial premises, magnetic contacts can be fitted to doors or windows.
A range of supply from 12V up to mains can be used to power the receivers.
Although the device is at the moment made in America it was designed in Britain.
Arma devices for all applications will be marketed through authorised security specialists in the UK.
