Frequently asked questions

Does Signaline FT need a controller?

Signaline FT, FT-R, FT-X linear heat detection cables do not need a controller to recieve the alarm signal from the cable. The cable creates a closed contact that can be monitored by a fire alar control panel. Therefore, Signaline FT, FT-R and FT-X linear heat detectors can be connected to a conventional fire control panel via a Signaline UCB (Universal Connector Box).

Signaline FT, FT-R, FT-X can also be connected to an addressable fire control panel without a controller. Simply connect the cable to an zone monitor unit.

If alarm location is required then you should use the Signaline LocatorPLus.

Does Signaline FT-EN need a controller?

Signaline FT-EN is approved to EN54 part 28. Although the Signaline FT-EN cables work in the same way as Signaline FT, the EN54 part 28 approval requires the cable to have a control device and end of line to monitor for system failure and faults. Our Signaline LocatorPlus-EN is also approved to EN54 part 28 and alongside the Signaline FT-EOL-EN can be used with Signaline FT-EN to complete an approved installation.

What should the difference between ambient and alarm temperature?

Signaline cables do not false alarm. However, unwanted alarms can occur when a cable is installed with an alarm rating to close to the ambient. Therefore, always allow at least 20°C between maximum expected ambient temperature and alarm temperature.

Please review the cable datasheets to see the recomend maximum ambient temperatures.

Where should I use the nylon coated cable?

Signaline FT-R range come with a nylon coating. This gives the cable increased chemical and UV protection to the cable. Therefore if there are harmful atmospheric gases or long exposures to UV rays you should consider the nylon coating for your cable.

Where should I use Signaline Stainless steel braided?

The stainless steel braid is designed to protect the cable from mechanical hazards. Therefore if the cable is going into machinery such as escalators or conveyors this would be the cable you should use.

We can apply the stainless steel braid to any of our standard HD, FT, FT-R, FT-X, FT-EN ranges of linear heat detection cables.

How much Signaline Fixed temperature Linear heat detection cable can you have per zone?

Signaline FT is capable of going into alarm at any point up to 3,000m. The Signaline LocatorPlus will give you a pinpoint reading as to where the cable has gone into alarm.

Signaline FT-EN is capable of going into alarm at any point up to 1,000m.

Can I use Signaline Linear heat detection cable on addressable systems?

Yes! Connect the cable to the suitable addressable interface.

Can I join lengths of different temperature Signaline Linear heat detection cable together?

You should never join different Signaline FT temperatures together.

Can I reuse a length of Signaline Fixed temperature Linear heat detection that has gone into alarm?

No, the length of cable affected must be replaced.

Can I splice a section of cable that has been damaged? What do I need to be able to do this?

Simply remove the damaged section and replace it with a new length of identical Signaline cable. Join the cable together using a Signaline UCB at each end of the replacement section.

What’s the maximum cable length of Signaline HD per controller?

The maximum length is 300m.

What’s the minimum cable length of Signaline HD per controller?

The minimum amount of cable per controller is 5 metre.

Can I join lengths of Signaline HD cable together?

Yes. Use a Signaline UCB (Universal Connectior Box) as the connection between the two lengths.

Can I reuse a length of Signaline HD that has gone into alarm?

Yes, providing it has not been destroyed.

Which Clip should I use?

The answer to this question depends on which cable you are using and the application you are using it for. Signaline offers a wide range of clips so we will always be able to match the correct clip to your application. Please contact our offices for advice on which clip to use.
