Key Features
- UL 521 approved and compliant with the EN54:22 draft standard
- Self-restorable analogue type system with optional pre-alarm setting
- Cable based sensing allows detection at the point of risk
- Low installation, maintenance and repair costs
- Reliable solution for hazardous areas
Overview
Polypropylene is the least common option and, although it is tougher than PVC, is mainly used for applications where strong acids are present or in corrosive environments.
Sensing Cable Construction
FyreLine Analogue Linear Heat Detection cable is constructed using a pair of copper conductors coated in a temperature sensitive polymer whose resistance changes as a function of temperature. A calibration resistance (white) and average ambient temperature sensor (red) core are also twisted with the two original conductors. A foil shield and protective outer coat is extruded over the twisted core.
Approvals
The FyreLine analogue linear heat detection cables are fully approved by the Underwriters Laboratories (UL) and bears the CE mark to show that they comply with all the applicable Directives including the CPR, EMC and the Low Voltage Directive (LVD).
