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.

The PIM-530 is a detection module that interfaces between a main control panel detection circuit(s) or addressable node(s) and Protectowire Linear Heat Detector. The module may be configured to provide two (2) Class B (Style B) alarm initiating circuits each capable of operating up to 2,000m (6,560 ft.) of Protectowire Linear Heat Detector or one (1) 3-wire Class B (Style B) dual input initiating circuit capable of operating up to 2,000m (6,560 ft.) of Protectowire Type TRI (TRI-WireTM). The PIM-530 initiating circuits are also compatible with other types of normally open non-resistive contact devices.

Protectowire Type XCR demonstrates excellent overall chemical resistance. In general only a few species are known to chemically attack the jacket and significantly swell the polymer causing damage to the jacket material.

The purpose of this guide is to ensure coverage of the area to be protected in accordance with accepted fire protection principles and to assure uniform installations. Whenever there is a choice between two or more possible procedures, the one which results in increased protection should be followed.

The PWM-D (ACR-1600 Series) and PDM-1000-1 (FS2000 Series) Alarm Point Location Meters are designed to locate a heat actuated point on Protectowire Linear Heat Detector. The Meter provides a means to display the alarm point location in feet or meters from the start of the Protectowire portion of the circuit to the heat actuated alarm point.

This Protectowire Alarm Point Locator Meter Adapter Model APL-90 is manufactured by the Protectowire Co. Inc.

The Protectowire Manual Fault Locator System MFL-92 is copmprised of two (2) modular units. A Tone Generator Model FDG-92 and a Tone Receiver Model FDR-92.

The CTM-530 is a detection control module that acts as an interface between a main fire alarm control panel detection circuit or addressable node and Protectowire Type CTI Linear Heat Detector.

Available in six alarm temperatures to accommodate a wide range of applications.

PHSC (Protectowire Heat Sensitive Cable) models are manufactured with steel conductors

Aircraft hangars present special fire protection problems due entirely to the nature of their contents. State-of-the-art high value aircraft, with expensive electronics and large fuel loads, present new challenges for fast reliable fire detection and suppression systems. Protectowire Linear Heat Detector and FireSystem control panels, provide an effective solution for the risks associated with this unique hazard.

Hostile environments – contaminated and combustible wood construction – difficult access for fire fighters – all render bridges and piers especially vulnerable to fire. Flexing timbers and extreme ambient temperatures compound the difficulties encountered in designing a fire detection system for these vital locations. These challenges are met by Protectowire Linear Heat Detector and controls in proven, long-term installations.

A relatively minor cable fire can cause widespread disruption and consequential losses out of all proportion to the incident itself. Protectowire Linear Heat Detector detects the location of an overheat condition anywhere in a plant’s cable tray system. Power and control cables are protected and vital systems are kept in operation.

Conveyor fires are typically caused by friction due to belt slippage, bearing problems, static electricity, welding operations adjacent to the conveyor or spontaneous combustion. Given the rapid spread of a fire on a moving conveyor, a Protectowire FireSystem designed for fast response can mean the difference between a controlled fire situation and a major disaster.

Protectowire Linear Heat Detectors are a proven, practical method of detecting overheat and fire in cooling towers. Fire is usually caused by overheating of a fan motor. Wooden tower framework and plastic impregnated fiberglass supports and dividers (fill) are an everpresent combustible hazard.

Protectowire Linear Heat Detector is a highly effective method of detecting fire in dust collectors/baghouses and overheating of associated motors.

Protectowire Linear Heat Detector is a simple cost-effective form of fire detection in floating roof fuel storage tanks. The Detector, when used with a Protectowire intrinsically safe control panel, provides early warning of lightning-caused fires in the seal area of tanks. The Detector can also be used to warn of overheating in the motor and shaft of the mixing blade.

Protectowire Linear Heat Detectors are readily adaptable to all types of conveyors used in material handling systems. The Detector will provide early warning of overheating throughout the entire system and can be used to protect auxiliary equipment and adjacent areas.

The inherent flexibility of Protectowire Linear Heat Detector permits installation in high risk areas such as motor control panels, switchgear, substations, transformers and resistor banks.

The origins of self-storage go back over 40 years when crude makeshift buildings began housing the belongings of migratory workers and seasonal tourists. The industry has grown as the economy has expanded and we have become an increasingly mobile society. With thousands of properties and millions of square feet under roof, this has become another natural application for Protectowire Linear Heat Detector and its unique properties.

The construction and environment of a vehicular tunnel poses unique and difficult fire safety problems. The life safety risks and potential danger facing people who travel through these enclosed structures are compounded when passengers are forced to evacuate through smoke-filled roadways or other emergency exits in the event of a fire.

Overheat and Fire Protection for Transformers

Protectowire provides the most dependable and cost-effective fire detection for refrigerated storage applications. When coupled with double interlocked pre-action sprinklers this system is virtually false alarm free.

The purpose of this guide is to ensure coverage of the area to be protected in accordance with accepted fire protection principles and to assure uniform installations.
