Abstract
A manually operated release and test apparatus is disclosed for use with mechanically powered protection devices. A spring powered fire alarm, for example, is triggered either by exposure of its sensitive fusing element to a predetermined temperature, or by complete physical removal of the sensitive fusing element from the device. The release and test apparatus of this invention is a lever mounted on the alarm device for the consistent removal of the fuse assembly for testing the alarm while avoiding inflicting any damage thereto. This apparatus facilitates the testing and demonstration of the alarm device, without modifying the aesthetic appearance of the alarm. Also disclosed is a chain attachment which permits a remote force to be directly applied to the release lever so as to provide a release and test means for manual activation of the alarm in emergency situations.
