Protectowire Linear Heat Detector is a proprietary cable that detects heat anywhere along its length. The sensor cable is comprised of two steel conductors individually insulated with a heat sensitive polymer. The insulated conductors are twisted together to impose a spring pressure between them, then wrapped with a protective tape and finished with an outer jacket suitable for the environment in which the Detector will be installed.

Digital Linear Heat Detector

Protectowire Digital Linear Heat Detector is the most widely used linear heat detector in the fire detection industry. It is a continuous heat detector capable of detecting heat anywhere along its length. The sensor cable is comprised of two steel conductors individually insulated with a proprietary heat sensitive polymer. The insulated conductors are twisted together to impose a spring pressure between them, then wrapped with a protective tape and finished with a protective outer jacket.

•     Detects at any point along its length providing uniform sensitivity.
•     Available in a wide range of operating temperatures and outer jackets.
•     Provides alarm point location with suitably configured control panels.
•     Simple design for easy troubleshooting and low maintenance costs.
•     Outer jackets resist corrosion, chemicals, dust, dirt, moisture, and temperature extremes.

Protectowire FiberSystem 8000

The Protectowire FiberSystem 8000 is known throughout the world as one of the reliable and intelligent linear heat detection systems using state of the art fiber optic sensing technology.
The system consists of Type PFS Fiber Optic Sensor Cable and the PTS Controllers with related software. The PTS Series Controllers can be configured for various alarm criteria and can be connected to an approved fire alarm control panel using relay inputs and outputs. The system is specifically designed for high risk commercial and industrial hazards that demand high reliability and customized system features.

•     Unique zoning capabilities. A single length of sensor can contain up to 256 zones.
•     Multiple alarm initiating criteria by zone.
•     Programmable custom operating logic.
•     Capable of continuous temperature monitoring in real time.
•     Graphic display of temperature profile, fire size, and spread using computer     interface.
•     LAN Interface (TCP/IP) enables remote access from multiple locations.

LHD Installation Accessories

The Protectowire Company offers an assortment of approved fasteners and splicing devices to facilitate installation for both standard and special applications. Protectowire supplied fasteners are generally designed to lightly clamp the detector which enables a tension to be applied progressively. This method is better than arrangements which apply a high tensile load at the end of each run or clamp and compress the sensor cable so tightly that the inner insulation becomes damaged. To ensure a trouble-free installation, only Protectowire supplied or recognized fasteners should be used.
