ProReact Analogue Linear Heat Detection

UL approved analogue linear heat detection

UL approved analogue linear heat detection system
CE and UKCA certified for European markets
A resettable system which means it not always necessary to replace the cable after an incident
Pre-alarm functionality providing an early indication of rising temperatures before an alarm point is reached
Compatible with Thermocable’s range of ProReact Accessories

Respond quicker

This unique sensor cable and its method of control continuously responds to changes in temperature. The technology offers the facility to programme an early warning pre-alarm as well as the specified alarm temperature. If the temperature surrounding the ProReact Analogue LHD cable reaches the pre-alarm point, the control unit triggers a warning giving the user time to survey the area at risk. Only when the temperature reaches the specified set alarm point will the control unit trigger full alarm.

Accurate alarm activation regardless of the environment

The optional two stage programmable alarm settings make the system and method of overheat detection incredibly flexible and ideal for use in a variety of different environments and applications. The technology automatically compensates for changes in the ambient temperature to maintain the accuracy of alarm temperature as well as offering up to 500 metres of continuous detection per control unit.

UL approval has been granted for two versions of control unit. One is a self-contained unit or, for finer control, a version requiring a laptop prevents uninvited system access. Both designs are compatible with any conventional panel or addressable fire system.

Frequently asked questions about ProReact Analogue Linear Heat Detection

Are there any specific installation considerations that must be taken into account when designing and/or installing a ProReact Analogue Linear Heat Detection system?

Thermocable recommends against installing its ProReact Analogue linear heat detection cable across varying ambient environments as this can interfere with the operation of the system. We recommend that multiple ProReact Analogue LHD systems are used in this instance (one for each different environment) or a digital linear heat detection system is installed as it would not be affected by varying ambient temperatures.
We also insist that the detection cable or end of line unit do not come into contact with any material that acts as a heat sink. A silicone sleeve (C1283) should be used to support the detection cable to a fixing clip to avoid heat transfer and end of line units should not be installed directly onto metal objects.
System designers and/or installers should ensure that the detection cable is spaced at less than or equal to the maximum approved spacing in the relevant or local building regulations or fire safety standards.

Which system components are covered by the UL certificate of compliance?

Please find below the list of components certified according to UL521:

ProReact Analogue LHD cable – PVC
ProReact Analogue LHD Cable – Nylon
ProReact Analogue Control Unit – Self-Programmable inc. EOL unit
ProReact Analogue Control Unit – Laptop-Programmable inc. EOL unit

What is the minimum and maximum zone lengths of ProReact Analogue Linear Heat Detection cable?

Cable zone lengths can vary from 30 metres to 500 metres in length.

What is the difference between the Self-Programmable and Laptop-Programmable control units?

UL approval has been granted for two versions of control unit. One is a self-contained unit or, for finer control, a version requiring a laptop prevents uninvited system access via a software programme.

Where can I download the software to commission a ProReact Analogue Control Unit – Laptop-Programmable?

Please contact us directly and we can provide this free of charge.

Can non-sensing (i.e. “leader cable”) be installed between a ProReact Analogue Control Unit and the ProReact Analogue LHD cable?

Yes. In certain applications it may be desirable or necessary to use non-sensing leader cable between a ProReact Analogue control unit and the detection cable. This may be required if the expected ambient temperature range, or other environmental conditions, where the Analogue LHD cable is to be used is greater than the maximum ambient temperature range for the control unit.

The maximum length of leader cable that can be used per ProReact Analogue LHD system is 250 metres. Thermocable can manufacture and supply leader cable that is compatible with its ProReact Analogue LHD cable. Please contact us or refer to the installation manual if you require further information.
