Abstract
A holder for a personal alert safety system (PASS) has a bracket to receive the PASS, and a housing connected to the bracket. An additional activation switch is installed in the PASS, the additional switch being magnetically operable. The housing is connected to the air line of a self contained breathing apparatus (SCBA). A piston or diaphragm is urged in one direction by air pressure, and is urged in the opposite direction by a spring in the absence of air under pressure. When the piston is moved in the one direction, a magnet is disposed adjacent to the additional switch, and when the piston is moved in the opposite direction by the spring, the magnet is removed from adjacent to the additional switch so the PASS is automatically activated by the presence of air pressure in an activated SCBA. The PASS can be used without the SCBA and can be activated manually as is conventional, either attached to or removed from the SCBA.
