Conventional Linear Heat Detection Cables

Linear heat detection provides early detection of fire conditions or overheating of equipment, plant or the surrounding area. Signaline linear heat detection cables are conventional heat detectors in a linear form. They sense heat anywhere along their length and are designed to be used in commercial and industrial applications. 

Heat sensing cables can be used with or in place of conventional heat detectors or where conventional heat detection is expensive or difficult to install and maintain.

Universal Connector Box

The Signaline Universal Connector Box can be used as an end of line unit, junction box or an interposing line unit. It is supplied with appropriately sized cable glands, terminal block and 470 and 680 resistors. These resistors allow Signaline FT cable to be connected directly to the zone terminals of most conventional fire control panels.

The IP66 rated enclosure provides a quick and efficient method to interconnect, terminate and join lengths of any Signaline heat sensing cable. It can also be used for connecting the incoming leader cable to the start of a length of heat sensing cable.

Note: Cannot be used with the E40007 cable.
