ABSTRACT:
Apparatus for the thermal and electrical initiation of fire protection devices including a housing with a displaceable support member and an abutment member provided therein. A blocking or spacing device is disposed between the displaceable support member and the abutment member with the displaceable supports member being biased against said blocking device in the direction toward the abutment member. The blocking device is responsive to the exceeding of a predetermined temperature for enabling displacement of the displaceable support member for initiating a fire protection device. The abutment member is constructed as a plunger displaceable within the housing in the direction towards the displaceable support member, and an electrically actuatable compressed-gas-generating igniter device is disposed on the side of the plunger facing away from the blocking device for producing compressed gas to cause displacement of the plunger toward the blocking device.
