NOTIFIER EPR and EPR-M Series Protectowire Linear Heat Detector

GENERAL

The System Sensor/Protectowire Linear Heat Detector is a proprietary cable that detects heat conditions anywhere along its length. It is considered a normally-open contact device and as such can be interfaced to a Notifier intelligent addressable fire alarm control panel via monitor modules: FMM-1, FDM-1, FMM-101, and XP10-M. 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.
Protectowire is a fixed temperature digital sensor and is therefore capable of initiating an alarm once its rated
activation temperature is reached. At the rated temperature, the heatsensitive polymer insulation yields to the pressure between conductors, permitting them to move into contact with each other, thereby initiating an alarm signal. It is not required that a specific length be heated in order to initiate an alarm, nor is system calibration necessary to compensate for changes in the
installed ambient temperature. Protectowire Linear Heat Detector provides the advantages of line coverage with point sensitivity.

The Detector must be installed in continuous runs without taps or branches in accordance with locations and spacing prescribed by the approving authorities; NFPA 70 National Electrical Code, NFPA 72 National Fire Alarm Code or as determined by the local authority having jurisdiction. Except for zoning requirements (alarm source indication) the length of each run is limited, and controlled by the electrical characteristics of the control equipment to which the Detector is connected.

FEATURES

Up to 1,000 ft. of the Protectowire Linear Heat Detector may be connected to the initiating device circuit of the addressable monitor module.
Eight different Linear Heat Detector models available, each packaged in 500 ft. rolls.
Fixed Temperature Digital Sensor
Line Coverage with Point Sensitivity
Wide Range of Industrial Applications, such as Aircraft Hangers, Manufacturing Facilities, Warehouses, Tank Farms, Coal Conveyors, Refrigerated Storage, Dust Collectors, Cooling Towers, Tunnels, and Floating Roof Tanks.
Good Abrasion Resistance
Excellent Weathering Properties and High Temperature Performance.
A comprehensive range of mounting and installation accessories are available.

EPR Series

The EPR series contains an extruded flame retardant jacket of polypropylene elastomer with a special UV stabilizer added to enhance weathering performance. It is intended for a wide range of industrial applications and is characterized by high resiliency, good abrasion resistance, excellent weathering properties and exceptional high temperature performance. Messenger wire is also available for any model detector. It consists of high tensile strength stainless steel wire, which is wound around the detector. It is a support wire, which is designed to simplify the installation of the detector in areas where mounting is difficult due to the lack of appropriate support structures or mounting surfaces.

EPR-M Messenger wire Series

Messenger wire (a Protectowire exclusive), is available with any of the four EPR models offered from Notifier. It consists of high tensile strength stainless steel wire, which is wound around the Detector at the rate of approximately one turn per foot (.3 m). It is a carrier or support wire which is designed to simplify the installation of the Detector in areas where mounting is dif ficult due to the lack of appropriate support structures or mount ing surfaces. When using messenger wire to support the Detector, turnbuckles and eyebolts must be employed at each end of a straight run to place tension on the support wire.

The distance between detector runs shall not exceed the listed spacing. Reduced spacing may be required based upon factors such as ceiling height and construction, physical obstructions, air movement, or the authority having jur isdiction (AHJ). When Protectowire is used for sprinkler system activation, special Factory Mutual (FM) reduced spacing guidelines may also be applicable.

Important Installation Information. Please Read!

Protectowire Linear Heat Detector may be installed at the ceiling level to protect areas within buildings (area protection) in the same fashion as the more familiar spot type heat detectors. Please refer to the National Fire Alarm Code, NFPA 72, for basic information on the installation and spacing of linear heat detectors for area protection. For special applications where the Detector is installed close to the hazard, the manufacturer’s recommendations and/or installation instructions should be followed. Whenever there is a choice between two or more possible installation procedures, the one which results in increased protection should be utilized.
For additional installation information on Protectowire Linear Heat Detectors please refer to the Installation/Operation/ Maintenance Manual (MAN 2001E-0603) and the Important Installation Information document (DS-7736) on www.Protectowire.com.

Protectowire Accessories

System Sensor offers an assortment of approved Protectowire fasteners and splicing devices to facilitate installation for both standard and special applications. Protectowire approved 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 approved fasteners should be used. The use of non-approved fasteners may physically damage the detector thereby causing “false alarms” and in some cases void the detector’s warranty.
