Two Wire Fire Alarm Systems

ESP MagDuo two-wire panels wire detectors and sounders onto a single pair of cables, cutting the cabling needed across a building. Panel kits arrive in a range of zone sizes, with matching control panels and repeater panels sold separately for larger layouts. A two-wire smoke and heat detector with built-in sounder and strobe completes the setup, and black finishes are available alongside the standard housing.

How two-wire systems work

A two-wire fire alarm system wires detectors and sounders onto a single pair of cables, so both the detection and the alert share the same run back to the panel. This cuts the amount of cabling needed across a building compared with arrangements that need separate runs, which can save time and material on an install while keeping the layout simple to follow.

What the range covers

This range is built around the two-wire panels. Panel kits arrive in a range of zone sizes to suit different building layouts, with matching control panels and repeater panels sold separately for larger sites. A two-wire smoke and heat detector with built-in sounder and strobe completes the setup, combining detection and alert in one fitting.

Panels and repeaters

The control panel is the hub that watches the zones and raises the alarm. Repeater panels mirror the main panel at a second position, so staff can see the system's state from another part of a larger building without walking back to the main unit, which helps on sites spread across several floors or wings.

Kits and finishes

Panel kits bundle the panel with matching devices so a system can be put together from one place, while standalone panels suit installs being extended or built up part by part. Black finishes are available alongside the standard housing, so the panel can be matched to the wall or scheme where it is fitted.

How to choose

Begin with the number of zones your building needs and pick a panel kit to match, or start from a standalone panel if you are building up gradually. Add repeater panels where staff need a second viewing point, the two-wire detector for combined detection and alert, and a black finish where it suits the setting. Free UK delivery over £99.

Frequently Asked Questions

What does two-wire mean in a fire alarm system?
Detectors and sounders share a single pair of cables back to the panel, rather than needing separate runs. This cuts the amount of cabling needed across a building.

What is the difference between a panel kit and a standalone panel?
A panel kit bundles the control panel with matching devices so a system can be put together from one place, while a standalone panel suits installs being extended or built up part by part.

What does a repeater panel do?
It mirrors the main panel at a second position, letting staff see the system's state from another part of a larger building without returning to the main unit.

Can I get the panels in black?
Yes. Black finishes are available alongside the standard housing, so the panel can be matched to the wall or scheme where it is fitted.

Does the two-wire detector also raise the alarm?
The two-wire smoke and heat detector has a built-in sounder and strobe, combining detection and the audible and visual alert in a single fitting.
