About us

  • A U.K. registered Company who design, Internationally sell and fully support its continuously increasing range of line type sensing equipment and access
  • We specialise in the special hazard area of linear detection. (no point detectors, control panels or audible devices included in the Company product range)
  • An operation who maintains a large inventory – ensuring shortest product lead times.
  • A Company who has Global market representation and installation references


  • Cable based overheat (fire PREVENTION) , incipient fire detection, chemical leak or frost protection equipment for multiple applications within an increasing number of adverse environments.....Industrial, Commercial and Domestic market sectors
  • As a combined cable and detector the sensor is able to provide an alarm as a result of an abnormal temperature change at ANY and ALL points along its installed length.
  • Optional extrusions / metal braiding to meet the requirements of a diverse range of life and investment "risk" areas.
  • A protection concept which allows installation at “point of risk” and within dirty, dusty, damp, corrosive and hazardous risk areas without fear of  generation of any unwanted alarm signalling.


  • A Factory Mutual (F.M.) approved and Underwriters Laboratories (U.L. & c U.L.) linear sensor cable range which can be installed in multi –kms lengths.
  • Sensor cable range meet the requirements of ALL existing and proposed global standards including NFPA72, EN54 and many other International certification authorities
  • Sensor cables are not affected by Radio Frequency Interference (RFI) or Electro-Magnetic Induction (EMI)
  • Sensor cables may be safely installed and operate within hazardous environments
  • Optional alarm point location feature
  • Optional remote alarm signalling to customer nominated cell phones by SMS messaging
  • Easily integrated into ANY conventional or addressable Fire Alarm or BMS Control system.
  • Sensor cables include:
    • Digital Overheat Detection, a New Generation of Analogue Linear Detection – with pre-alarm option,
    • Rate of Change Detection - temperature rise or fall,
    • Heating Cable - providing frost protection of pipework,
    • Moisture Detection Cable - providing protection against water leaks


  • Originally developed for overheat or incipient fire protection of Power Plant cable tunnels / trays, Mining conveyors, bulk / racked storage & Petro-chemical fuel storage tanks.
  • PROLINE Is able to provide fire PREVENTION, rapid detection of overheat or incipient fire conditions, water leak detection and frost protection within an increasingly diverse range of risk areas, including escalators, elevators, tunnels (road & rail), car parks, buildings ( manufacturing plants, prisons, museums, churches or other listed buildings), forest fires, LNG Pipelines, data centres, hotels, schools, building ceiling /floor voids, control rooms and MANY MORE!


Digital (LHS) & Analogue Linear Sensing

The means to locally monitor for temperature changes (rise or fall) at "point of risk" and at ANY /ALL locations along an installed length of temperature sensitive cable - regardless of environmental conditions.

Fibre Optic Linear Temperature Sensing

Line detection of temperature change and rate of rise along multi -kms lengths of small diameter fibre optic cable. It provides high performance near real time temperature Sensing and Alarm functionality with standard communication interfaces.

Proline 'Nero' Water & Moisture Detection

Rapid detection of the smallest of leaks within Industrial, Commercial Environments by a recoverable cable. Designed to provide 24 hours/day x 7 days/week continuous monitoring of areas where even the smallest of leaks can prove disastrous. Essential where undetected leakages can cause serious damage to today’s complex electrical, communications and computer networks.



A U.K. registered Company with hands-on product development, global market & application experience dating from the 1970's.

Proline equipment conforms to all NFPA 72 and EN54 standards requirements for linear detection.

Pneumatic, Digital, Analogue, Fibre Optics, Measuring Point System, Aspirating Systems...regardless of your linear detection requirement PROLINE will be happy to assist you.
