Signaline Catenary Wire is an optional wire applied to any Linear Heat Detector cable. Available as an optional addition to any of the Signaline Linear Heat Detection cables.
Signaline Catenary Wire aids in installing Signaline Linear Heat Detectors in areas which may be difficult to access, have large spans to cover or fixing the cable at the normal recommended spacing would be too difficult or time consuming.
The catenary wire is spiralled around the cable and makes the linear detector cable self-supporting.
A turnbuckle hook and support is sold separately to complete the installation.

What components do I need for a Linear Heat Detection system?
For Signaline HD+ Programmable Linear Heat Detection:
Linear Heat Detector systems use a line-type heat detection cable which is monitored by a front end controller and terminated in an end of line box.
Signaline HD+ is made up of the HD+ Controller, a choice of HD+, HD+R or HD+SS detection cable and the HD+ EOL unit. The cable can also be supplied with catenary wire if required.
Minimum length of cable required is 50m.
For Signaline FT-EN Linear Heat Detection:
Linear Heat Detector systems use a line-type heat detection cable which is monitored by a front end controller and terminated in an end of line box.
Signaline FT-EN is made up of the LocatorPlus-EN, a choice of FT-68-EN, FT-78-EN, FT-88-EN detection cable and the FT-EOL-EN unit.
There is no minimum length of cable required. Furthermore, the LocatorPlus-EN and FT-EOL-EN are capable of monitoring two zones of cable. Therefore, if site allows, you can use one LocatorPlus-EN and one FT-EOL-EN for two lengths of detection cable.
For Signaline FT Linear Heat Detection:
Linear Heat Detector systems use a line-type heat detection cable which is mointored by a front end controller and terminated in an end of line box.
However, Signaline FT is UL and FM approved as a stand alone device. Meaning that you do not need to use the LocatorPlus or FT-EOL. You can simply install a length of Signaline FT detection cable and connect directly into the zone terminals or interface unit for your fire detection system.
There is no minimum length of cable required.
Furthermore the LocatorPlus and FT-EOL are capable of monitoring two zones of cable. Therefore, if site allows, you can use one LocatorPlus and one FT-EOL for two lengths of detection cable.
How do I test Linear Heat Detection?
For Signaline HD+ Programmable Linear Heat Detection:
Linear 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.
For Signaline HD+, once an alarm threshold is reached it is important to let the cable cool before resetting the controller. The cable does not need to be replaced as long as the testing did not exceed 120°C.
Where it is not possible to live-test the linear heat detection cable due to installation restraints, the Signaline HD+ test PCB can be used. Please refer to the Signaline HD+ manual for further details.
For Signaline FT-EN Linear Heat Detection:
Linear 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.
For Signaline FT-EN, testing can also be performed by opening the FT-EOL-EN unit and pressing the test switch.
If live heat testing is performed, the tested section will need to be replaced.

Which clip should I use to secure Linear Heat Detection?
For Signaline HD+ Programmable Linear Heat Detection:
The correct choice of clip depends on the specific enviornment, 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.
You can review a full list of Signaline Linear Heat Detection clips.

Is Linear Heat Detection resettable?
Linear Heat Detection comes in different forms and is based on different detection technologies. Therefore not all linear heat detection can be reset after an alarm.
Signaline HD+ Programmable uses an analogue linear heat detection cable to continuously monitor for overheating by measuring electrical changes within the different cores inside the detection cable.
Due to this detection methodology, the cable can be reset after an alarm event.
Can I use Linear Heat Detection in the Hazardous Area?
For Signaline HD+ Programmable Linear Heat Detection:
For electrical equipment to be used within a designated Hazard 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.
