The Digital Interface Monitor Module (DiMM) is a dual zone module for monitoring up to two zones of Digital Linear Heat Detection (DLHD) Cable.
If an overheat or fire situation triggers either zone of the Digital LHD cable, the unit automatically calculates and displays the distance along the cable, in feet and metres, to the alarm point. The two zones can operate independently of each other, or in interlock mode and a separate alarm and normally conducting fault output are provided for each zone.
The unit is intended to be installed between the FyreLine Digital Linear Heat Detection cable and a conventional or addressable fire alarm control panel. It has power, fault and alarm lights, as well as volt free outputs for fault and alarm, corresponding to each zone. It may also be connected to an industrial process control system using the two wire RS-485 Modbus RTU output.
FyreLine Digital End of Line Units with Incorporated Fitted Test Switch are suitable for use with FyreLine Digital linear heat detections systems, can monitor up to two LHD cables or zones and offer hassle-free functional testing of the system.
End of Line (EOL) units are used together with Interface modules to terminate linear heat detection cable and contain the appropriate EOL component or device. This allows the module used to monitor the linear heat detection system for any open circuit fault conditions.
FyreLine EOL units go one step further. Thanks to their carefully designed printed circuit board, FyreLine EOL units incorporate a test switch that allows the user to simulate trouble, fault and alarm conditions. Using the fitted test switch, users can verify normal conditions, trouble/fault conditions and alarm functions by simulating a break in the cable or an overheat condition.
The stainless steel braided linear heat detection cable provides the ideal solution for areas where the cable may be accidentally cut or where it may be subject to mechanical abrasion.
The High Temperature coated linear heat cable is manufactured from two different types of nylon, with the outer sheath being a chemical resistant material. Commonly used in high temperature areas, hazardous and safe areas where chemicals such as hydrocarbon fuel oils, diesel, kerosene etc. are present.
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. An additional stainless steel braiding over the outside of the cable is included thus providing protection for areas where the cable may be accidentally cut or where it may be subject to mechanical abrasion.

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 Non-Sensing Leader Cable is manufactured to the same specifications as the sensing cable and provides accurate resistance readings to ensure that the FyreLine detection system operates effectively. There are two leader cable coating options available to ensure that the cable meets the requirements of the environment:
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 (e.g. 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.

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.
