Fire Alarm Installation London

Professional, Compliant Systems by Spycon Security Ltd

In London, fire safety is not just about compliance — it’s about protecting lives, property, and your legal responsibility as a landlord or business owner.

At Spycon Security Ltd, we design, install, and commission fully compliant fire alarm systems across London. Whether you need a Grade D system for a rental flat or a full Grade A panel system for a large HMO or commercial building, we ensure your installation meets:

  • BS 5839-1 (Commercial Fire Alarm Systems)
  • BS 5839-6 (Domestic Fire Alarm Systems)
  • Regulatory Reform (Fire Safety) Order 2005
  • Fire Safety Act 2021

Fire Alarm Installation Designed for London Properties

London buildings vary widely — Victorian conversions, modern apartment blocks, mixed-use commercial units, and licensed premises.

A “one-size-fits-all” approach does not work.

We design systems based on:

  • Your Fire Risk Assessment
  • Building layout and escape routes
  • Number of storeys
  • Occupancy type
  • Local authority expectations
  • Insurance requirements

Our goal is simple: a compliant, reliable system that works when it matters most.

Understanding Fire Alarm Grades: Grade A vs Grade D

Under BS 5839, fire alarm systems are classified by Grade (how the system is built) and Category (where protection is provided). Choosing the correct grade is critical for compliance in London.

What Is a Grade A System?

A panel-based fire detection and alarm system designed to BS 5839-1.

It includes:

  • Central fire alarm control panel
  • Smoke detectors
  • Heat detectors
  • Manual call points (break glass units)
  • Sounders and warning devices
  • Mains power with central battery backup
Key Performance Standards
  • Minimum 65 dB(A) in general accessible areas
  • 75 dB(A) at bed head positions where occupants sleep
  • Zoned detection for clear identification of activation location

Grade A systems offer the highest level of life protection and are typically mandatory for larger London HMOs.

Grade D Fire Alarm Systems – Domestic & Small HMO Protection

Grade D systems are common in:

  • Single-family homes
  • Flats
  • Small HMOs (1–2 storeys)
  • Individual dwellings within blocks

Designed to BS 5839-6, these systems consist of:

  • Mains-powered smoke and heat alarms
  • Interlinked units (wired or wireless)
  • Integral battery backup
Grade D1 vs D2
  • Grade D1 – Sealed long-life tamper-proof battery
  • Grade D2 – Replaceable battery backup

All alarms are interlinked so activation in one room triggers all alarms — essential for early warning.

Legal Requirements for London Landlords & Businesses

Under the Regulatory Reform (Fire Safety) Order 2005, the “Responsible Person” must ensure:

Failure to comply can result in enforcement action, fines, or prosecution.

Spycon Security Ltd ensures you meet your legal obligations.
