Fire Alarm Installation

Guardian Edge designs, installs and commissions fire detection and alarm systems to BS 5839 across the UK, from single-panel conventional systems in small premises to addressable and networked systems across multi-building sites — including takeovers of existing systems and replacement of obsolete panels.

Designed to the right category for the building — not the cheapest one.

Who this is for

  • Businesses fitting out or refurbishing premises
  • Landlords and managing agents of residential blocks and HMOs
  • Property managers replacing an obsolete or unsupported panel
  • Facilities teams extending detection into a new area
  • Anyone whose fire risk assessment has identified inadequate detection

Problems it solves

  • The existing panel is obsolete and parts are no longer available
  • Detection does not cover the whole escape route
  • The system was designed to a lower category than the current use warrants
  • Repeated false alarms are eroding confidence in the system
  • A change of use or layout has left the design no longer valid
  • Building control or an insurer has asked for a system that does not exist yet

What Guardian Edge provides

Our fire alarm installations scope

What we provide

  • System category assessment — establishing whether L1, L2, L3, L4, L5, P1 or P2 is appropriate
  • Full design to BS 5839-1 (non-domestic) or BS 5839-6 (domestic premises)
  • Conventional, addressable, networked and wireless systems
  • Panel replacement and takeover of existing field devices where they remain suitable
  • Cause-and-effect programming, interfaces to plant, door holders, lifts and AOVs
  • Commissioning, certification, logbook and demonstration to your team

Typical scope

  • Offices, retail, industrial units, warehouses and logistics sites
  • Residential blocks, HMOs, student accommodation and supported housing
  • Schools, healthcare premises and public buildings
  • Multi-building estates requiring networked panels and a head-end
  • Phased installation in occupied buildings, out of hours where required

Before we price anything

Inspection & survey process

  1. 01

    Establish the fire strategy

    Occupancy, sleeping risk, escape routes, phased or simultaneous evacuation, and any existing fire risk assessment.

  2. 02

    Agree the category

    L-categories protect life, P-categories protect property. We explain what each level actually covers before you commit to a spend.

  3. 03

    Design the system

    Device selection, zoning, sounder coverage, cable routes and interfaces — issued as a drawing and a specification.

  4. 04

    Price it properly

    Itemised, including commissioning and certification. No provisional sums that inflate later.

On site

How the work is delivered

  1. 01

    Programme and access

    Agreed dates, isolation arrangements and any out-of-hours working.

  2. 02

    First fix

    Containment and cabling installed to the design, with routes kept clear of hazards.

  3. 03

    Second fix and programming

    Devices, panel, interfaces and cause-and-effect configured to the agreed strategy.

  4. 04

    Commissioning

    Every device tested, sound pressure levels verified, interfaces proven, and the system demonstrated to your staff.

  5. 05

    Certification and handover

    Design, installation and commissioning certificates, as-fitted drawings, zone plan and logbook.

Compliance

What the rules actually require

  • BS 5839-1 categories are not interchangeable. An L3 system protects escape routes and rooms opening onto them; an L1 system covers all areas. Choosing a lower category to save cost has to be a deliberate, recorded decision — not an accident.
  • The Regulatory Reform (Fire Safety) Order 2005 requires the premises to be equipped with appropriate fire detection and alarm arrangements. It does not name a category — that comes from the fire risk assessment.
  • A system is only compliant once it has been commissioned and certificated. An installed but uncommissioned system is not evidence of anything.
  • Where an existing system is taken over, we record its condition honestly at the point of takeover rather than inheriting someone else's paperwork.

Standards & legislation

These are not all the same kind of obligation, and we do not present them as if they were. A statutory duty is law. A British Standard is the recognised way of demonstrating you have met one. Guidance and our own recommendations are neither.

  • British StandardBS 5839-1

    Fire detection and fire alarm systems for buildings — non-domestic premises

    Code of practice for system design, installation, commissioning and maintenance. Defines the L and P categories.

  • British StandardBS 5839-6

    Fire detection and fire alarm systems in domestic premises

    Applies to dwellings, including HMOs and individual flats. Defines LD and grade classifications.

    Requires appropriate fire detection and warning arrangements determined by the fire risk assessment.

Ongoing support

Planned, reactive and multi-site.

Most providers do one of these well. The value of a single provider is that the schedule, the emergency and the portfolio all sit in the same place.

Planned maintenance

  • The new system enters a servicing calendar at handover
  • Servicing to BS 5839-1 intervals from the commissioning date
  • Battery and device lifecycle tracked against the asset register

Reactive support

  • Fault attendance under the same contract as the installation
  • False alarm investigation and cause analysis rather than repeated resets

Multi-site & national portfolios

  • Consistent panel platform across a portfolio so your team learns one interface
  • Networked head-end where sites share a campus
  • One design standard applied estate-wide

Procurement, simplified

    Carried out by directly managed engineers or vetted specialist subcontractors.

  6. 06

    Evidence is supplied

    Certification, test records and photographic evidence where the work calls for it.

Answers

Fire Alarm Installationsquestions.

What is the difference between L1, L2, L3 and L4 fire alarm systems?
They are BS 5839-1 categories describing how much of a building is covered by automatic detection. L1 covers all areas of the building. L2 covers escape routes, rooms opening onto them, and specified high-risk rooms. L3 covers escape routes and rooms opening onto them, giving warning before escape routes become impassable. L4 covers escape routes only. L5 is a custom category designed around a specific risk. P1 and P2 are property protection categories, driven by insurance rather than life safety. The correct category comes from the fire risk assessment, not from a price list.
Can you replace the panel and keep the existing detectors?
Sometimes. It depends on the age, type and condition of the field devices and whether they are compatible with a current panel. We survey before we commit to it, and we will tell you if a partial replacement would leave you with a system that is harder to maintain than a full one.
How long does a fire alarm installation take?
A small conventional system in a single unit is usually a day or two. An addressable system across a multi-storey occupied building is typically phased over several weeks so that detection is never wholly absent. We give a programme with the quotation rather than an estimate on the day.
