Addressable Fire Systems

Addressable systems pinpoint exactly which device has triggered, making faults and alarms quicker to locate across a larger site. This ESP MagPro range covers 16 and 96 zone control panels, loop expanders for added devices, a battery expansion box and a programming tool, plus addressable call points, sounder strobes and relay and output modules. Everything is built to work together on one loop.

What an addressable fire system covers

An addressable system links every device on a single loop and reports back exactly which one has triggered, so a fault or an alarm can be traced to a precise location across a larger building. The range here brings together the control panels that watch the loop, loop expanders that let you add more devices, a battery expansion box and a programming tool for setting devices up, alongside the field devices themselves: manual call points, sounder strobes, and relay and output modules that drive ancillary equipment.

How the parts work together

The panel sits at the centre and polls each device on the loop in turn, giving every one its own identity. Call points let someone raise the alarm by hand, sounder strobes alert occupants with sound and a flashing light, and output modules switch linked equipment when the system activates. Because the devices share one loop rather than separate radial circuits, wiring stays simpler on a site with many rooms or floors.

Who it suits

Addressable systems are aimed at larger and more complex premises, where knowing the exact source of an alert saves time and where the number of devices would make a simpler layout harder to manage. Commercial buildings, sites split across several areas and properties that may grow over time tend to benefit most, since loop expanders allow more devices to be added later.

How to choose

Start with the size of the site and the number of devices the loop needs to carry, then pick a panel that matches and add expanders if the device count is high. Choose call points and sounder strobes for each area people occupy, and add output modules where the system needs to switch other equipment. Finishes such as grey and red help devices stand out or blend in as needed. Free UK delivery over £99. Worldwide delivery priced at checkout.

Frequently Asked Questions

What does addressable mean on a fire system?
Addressable means every device on the loop has its own identity and reports individually to the panel. When a detector or call point activates, the panel shows which specific device it was, so the source of an alarm or a fault can be found quickly rather than narrowed down by zone.

What is included in an addressable fire range?
The range covers control panels, loop expanders for adding more devices, a battery expansion box and a programming tool, plus field devices such as manual call points, sounder strobes, and relay and output modules. These are designed to work together on one loop.

How do loop expanders help?
Loop expanders increase how many devices the system can support. They let you add further call points, sounders and modules as a building grows or as more coverage is needed, without starting again with the wiring.

What is the difference between a sounder strobe and a call point?
A manual call point lets a person raise the alarm by hand. A sounder strobe is an output device that warns occupants once the system has activated, using sound and a flashing light so the alert is both heard and seen.

Can I add more devices later?
Yes. Because the system is built around a loop with expanders, further devices can be added when the site changes. Plan the panel and expander capacity around the devices you expect to need.
