The FyreLine Analogue Heat Detector is a rugged, easy-to-install detection system, consisting of a control module and detection cable, that is designed to interface with a standard fire alarm panel or addressable monitor module.
The FyreLine analogue control modules and PVC coated 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).
Heat sensing cables are capable of detecting heat anywhere along their length and designed for use in a vast range of applications and environments from tunnels, cable trays, racking to sensing changes in temperature within escalators and other applications where many risks of fire are hidden from view. Linear heat detection is highly cost-effective and can be easily installed with, or in place of, conventional heat detectors where traditional style detection may be difficult to install or maintain or is too expensive.
FyreLine Analogue Heat Detectors automatically compensate for changes in ambient temperature to maintain the accuracy of the alarm temperature and offer up to 500 metres of continuous detection per control module. This flexibility makes FyreLine Analogue Heat detectors extremely flexible for use in a wide range of applications.
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 twisted with the two original conductors. A foil shield, outer sheath and optional protective coating is extruded over the twisted cores.
When the temperature around the cable reaches pre-alarm temperature the control module triggers a warning, giving the user time to investigate and take any necessary action. The control module will only trigger full alarm when the temperature reaches a specified alarm point.
After an alarm is triggered the system can simply be reset with little disruption. FyreLine Analogue Linear Heat Detection cable is ‘self-restorable’ so does not need to be replaced unless it has become severely damaged.
The standard coating used on Analogue cables is made from PVC and is suitable for most environments. However, PVC should not be used when the cables are directly exposed to UV (sunlight) or hazardous chemicals (eg. hydrocarbons) for long periods, or for applications where they may be exposed to regular mechanical abrasion.
Where the standard PVC is not recommended other materials/sheaths are available to provide a suitable solution.
A Nylon coated cable is the common choice when hazardous hydrocarbons such as fuel oils, diesel, kerosene etc. are present. Nylon cables are coloured black and provide suitable UV protection when used in direct sunlight. Nylon is much tougher than PVC and therefore provides additional mechanical protection.
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.
Any of the above cables can be armoured by placing stainless steel braiding over the outside of the cable. This provides the ideal solution for areas where the cable may be accidentally cut or where it may be subject to mechanical abrasion.
The analogue linear heat detection control module can be connected directly to a single zone of a conventional fire alarm control panel, or, easily interfaced to an addressable loop using an addressable zone/switch monitor.
The analogue control module is designed for use with FyreLine Analogue Linear Heat Detection cables. The control module interfaces between a fire alarm control panel or addressable module and a single zone of Analogue Linear Heat Detection cable.
The control module monitors the resistance of specially doped polymers within the sensor cable which change as a function of temperature. An abnormal change in resistance along the detection cable triggers either a pre-alarm or alarm on the interface module. The unit is intended to be simple and straightforward to install. Commissioning of the controller can be done using a standard laptop computer or a built-in self-programming module.
The Analogue control module complies with the latest standards and is housed in an IP66 rated enclosure.
FyreLine Analogue Linear Heat Detection Cable should be connected to a conventional fire alarm control panel via the initiating device circuit.
In the circumstance that the area to be protected is some distance away, leader cable may be used between the FyreLine control module and the fire alarm control panel.
When using FyreLine Analogue Linear Heat Detection in conjunction with an addressable fire alarm system it should be connected onto the addressable loop using a switch or zone monitor. An external power supply is needed for the FyreLine control module.
