HEAT DETECTOR WITH SHAPE METAL ALLOY ELEMENT

Kidde Technologies, Inc.,...

1. A temperature sensing system comprising:
a conductive tube;
a shape memory alloy (SMA) element disposed to create an electrical connection with the conductive tube when subjected to
at least a critical temperature; and

a detector configured to identify an alarm condition when the conductive tube and the SMA element form a closed electrical
circuit; and

a piezoresistive sleeve disposed between the SMA element and the conductive tube, and configured to act as a conductor when
strained by a shape change of the SMA element.
