Patent ID: 8648711

Claim:
An apparatus for wireless communication between a Linear Heat Detector system and a Fire Control system comprising in combination: a cable consisting of two conductors having a residual stress and separated by an insulating material, the cable forming part of the Linear Heat Detector system; a Remote Unit having a connection with the cable that uses sufficiently low voltage and low power to avoid igniting flammable vapors; a Communication Unit connected to the Fire Control system, the Communication Unit being in wireless communication with the Remote Unit, wherein the Communication Unit relays status and control signals between the Fire Control system and the Remote Unit, the connection between the cable and the Remote Unit normally showing no current flow as long as the two conductors remain separated by the insulating material, upon an ambient temperature reaching the melting point of the insulating material, the conductors push their way through the insulating material contacting one another to create a short-circuit condition resulting in current flow to the Remote Unit which is communicated by the Remote Unit to the Communication Unit; and the Remote Unit is self-powered using solar cells, batteries, or a combination thereof.
