ABSTRACT:
An actuator for a personal protective spray canister having a container for holding a pressurized protective material capable of being propelled in a gaseous cloud to at least partially disable a person and a manipulative valving device protruding outwardly from the container, with the valving device having an outlet for directing the gaseous cloud from the container, and a valve element movable between a first biased normal position closing the outlet and a second depressed operative position opening the outlet to allow the material to be propelled from the container as a cloud. The actuator comprising: a radio frequency receiver for detecting and receiving a coded radio frequency signal, a decoder for creating an identification signal when the receiver receives a radio frequency signal with a preselected code, a mechanical device for moving the valve element into the second depressed, operative position in response to a danger signal, a circuit for creating a danger signal in response to a given number of identification signals, a power supply for providing power to operate the mechanical device to depress the valve element when the actuator is operatively associated with the valve element of the container.
