EN54 -22 / EN54-28

Line type heat detectors

There have been references made to the above DRAFT standards by individuals or Corporate bodies which clearly indicate a mis-understanding of current EN54 requirements in relation to line type heat detections systems.

There currently exists NO ACTIVE STANDARD FOR ANY LINEAR TEMPERATURE SENSING SYSTEM OF ANY MANUFACTURE OR OPERATING CONCEPT. Any reference to EN54-5 is totally irrelevent because this standard was written exclusively for POINT type heat detectors! As a combined cable & continuous detector, linear temperature sensing can be installed close to the point of risk....not the most convenient roof /ceiling height AND will monitor for alarm conditions at ANY &  ALL points along its installed length. It is not more sensitive where temperature rise is directly beneath the detector and it does not rely on favourable air flows for increased sensitivity.

EN54-22….."restorable" line type heat detectors    ............position @ 30 May 2014 as advised by British Standards Institution (BSI)

BS EN 54-22 is scheduled for publication on 01 December 2014

EN54-28…..Non-resettable line type heat detectors  ......position @ 30 May 2014  as advised by British Standards Institution (BSI)

BS EN 54-28 is scheduled for publication on 19 October 2014


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.
