Linear Heat Detector fixing clip
Signaline J Clip is a knock on clip designed for fixing linear heat detection to steel work of differing thickness.
These fixings are available in mild steel with a zinc rich plated finish or for enhanced corrosion resistance use the SS316L version
Signaline Linear Heat Detection cable must be secured to the J Clip with the neoprene sleeve to ensure no heat transfer to the line-type detection cable.
Ties wraps are included.
Made in the UKLinear Heat Detection forms part of a building’s life safety equipment and therefore regular testing is essential. Functional testing can be performed by using a suitable heating element on the line-type detection cable to simulate an alarm.
Across our ranges, Signaline Linear Heat Detection can either be directly tested using a heat source or utilising internal functionality on the controllers we offer.
For Linear Heat Detection:
The correct choice of clip depends on the specific environment, mounting surface and local regulations in which the linear heat detection is being used.
For EN54 approved solutions the cable should always be mounted with a metal fixing clip that allows a 20mm drop from the fixing surface. This allows air-flow around the line-type heat detector and ensures quick activation in an alarm event.
Specialist clips are necessary for use in specific environments, such as floating roof tanks and cable trays.
When there is no easy mounting surface e.g. due to non-flat surfaces or apexed roofs, consider the use of a catenary wire solution.

For electrical equipment to be used within a designated Hazardous Area the items should be certified safe for use. This is normally done by encapsulating the electronics inside a Flame Proof enclosure or ensuring the power consumption is below a minimum threshold to not be an ignition risk (Intrinsically Safe).
Many Linear Heat Detectors are defined as Simple Apparatus. This means, by themselves they do not have the electrical energy to be an ignition source.
Simple Apparatus can be used within the hazardous area, and this is the case for Signaline Linear Heat Detectors.

The minimum and maximum zone length for Linear Heat Detection will depend on the approval of the line-type heat detector and the local regulation.
En54 part 22 approved systems are limited to 500m per zone and require a minimum of 50m.
En54 part 28 approved systems are limited to 1000m per zone and have no minimum length.
UL, cUL and FM approved systems are limited to 3000m per zone and have no minimum length.
Signaline Linear Heat Detection cable is sold in 50 metre lengths, so the minimum order is 50 metres.
We offer reels in 50-metre steps—such as 50m, 100m, 150m, and so on—up to 500 meters for FT-EN and HD+ cables, and up to 1000 metres for FT cables.
