ABSTRACT:
Apparatus for fire protection purposes including a compressed-gas cartridge device with at least a thermally responsive triggering mechanism. The triggering mechanism includes a striker for forcibly being driven toward the compressed-gas cartridge device and a locking device for maintaining the striker at a spacing from said compressed-gas cartridge device by engaging a portion of said striker pin with one end portion thereof. Another end portion of the locking device is biased against a blocking device with the blocking device being disposed between the another end portion of the locking device and an abutment member. The blocking device is responsive to the exceeding of a predetermined temperature for enabling displacement of the locking device out of engagement with the striker thereby permitting movement of the striker toward the compressed-gas cartridge device.
