Figure 11 - Linear Thermal Wire
Linear thermal wire allows for continuous thermal monitoring of wide coverage areas.
Field wiring connecting the SDRP to linear thermal wire allows an electrical current to
flow through the detection circuit, through an End of Line device completing a loop back
to the SDRP. If a Fire occurs, the outer and inner insulating jackets of the linear thermal
wire melt allowing the individual conductors of the linear thermal wire to electrically “short”
together. This change in electrical resistance is interpreted by the SDRP as a Fire
condition. The SDRP sends an electrical signal to the Stat-X generator(s) automatically
discharging the system. Linear thermal wire is available with alarm temperature ratings
of 135
