ABSTRACT:
An activation indicator for a fire detector wherein fusible securing means, such as solder, or the like, is fixed to and positions an attachment member in proximate heat exchange relation with a fire detector, and resilient means is connected to the attachment member urging the latter out of its heat exchange position, elevated temperature serving to melt the securing means and free the attachment member for movement by the resilient means out of its original position, to thereby indicate activation of the fire detector by the elevated temperature.
