Meet the Alarm Range That Matches Aico for Performance – and Challenges It on Value

ESP Espire Smoke and Heat Alarm Range Explained — this guide takes a close look at the full product lineup from ESP, built to meet modern UK fire safety needs. With advanced RF-Link technology, dual sensors, and modular install tools, Espire is fast becoming a leading choice for domestic protection.


🛡️ ESP Espire Smoke and Heat Alarm Range Overview

The Espire alarm range by ESP is a complete fire and carbon monoxide safety system designed for UK housing regulations. It includes:

  • Optical smoke, heat, and CO alarms
  • Dual-sensor alarms (CO + Heat, Smoke + Heat)
  • 10-year sealed lithium battery or mains-powered options
  • Plug-in RF-Link wireless modules
  • Remote controllers, relay bases, masking plates, and tools
  • Full compliance with EN and BS standards (Grade D1/D2)

Whether you’re fitting out a new build, upgrading social housing, or managing rental units, Espire delivers a modern, modular solution for domestic safety.


🔄 Installation: Same as Aico – Fast and Familiar

The ESP Espire Smoke and Heat Alarm Range Explained makes clear how installation is streamlined with universal backplates, clear wiring points, and lock-in bases. Whether you’re retrofitting an HMO or starting from scratch on a new build, the Espire system keeps install times consistent with Aico — while offering greater flexibility through modular RF-Link options. Installers can configure up to 28 devices, using either mains or battery power, all with a clean, professional finish.

Installers switching from Aico will feel right at home:

  • Standard backplate spacing
  • Fast-fit locking bases
  • Clearly marked terminals
  • LED indicators for power, fault, and alarm
  • Tools included for base release and RF pairing
  • 28-device interconnect capacity via RF-Link

Installation time is the same as Aico. But Espire includes many tools and accessories in the core range — no need to source extras.


One of the standout features in the ESP Espire Smoke and Heat Alarm Range Explained is the ability to mix and match power sources, sensor types, and mounting styles — without affecting interconnect performance. You can link heat alarms in kitchens, CO detectors in boiler cupboards, and optical smoke sensors in living rooms — all wirelessly, using RF-Link. This flexibility is especially valuable in large or complex properties where wiring every detector isn’t practical.

  • Works across both mains and battery-powered alarms
  • Supports up to 28 devices in a single network
  • Compatible with relay bases and remote controls
  • Easy setup using included tools or pairing buttons
  • Uses secure 868.3 MHz communication

🆚 Aico systems support just 12 interlinked devices wirelessly. Espire’s RF capacity gives it a clear edge for larger properties or more complex layouts.
