ABSTRACT:
A resettable fire link includes a first member (12) that pivotally supports a latch arm (20) thereon with a bi-metallic coil spring (30) interposed between the first member and the free end of the latch arm to normally bias the latch arm into a latched position with a release plate (50). The bi-metallic coil spring pivots the latch arm to a release position upon being elevated in temperature.
