(54)	Wireless alarm system with radiofrequency transmission of coded signals

(57) Radiofrequency-based alarm sensors (2, 3) send their coded signals of possible intrusion to the alarm gear-case (1) which, even if it is switched off, is so set as to emit an acoustic and/or light signal of environmental control.
Once the alarm is switched on, the gear-case (1) receiving stimulation from the sensors, signals the intrusion causin the emission of the alarm.
