Roof height and stack height decide the detection. Beam, aspirating and in-rack rather than more point detectors.

What it needs
The tests, weekly to annual
Illustration only. This model shows how a fire alarm system and the fire safety around it work. It is not a design for any real building: the number and position of detectors, call points, sounders, emergency lights, extinguishers and fire doors in it are not the ones your building would need. Every real system is designed for its building after a survey and the fire risk assessment, to BS 5839-1, BS 5266-1 and BS 5306. Open the builder on its own page.

The four badges, and what each one is actually worth

Manufacturer training and authorisation on the Fike platform, including parts and technical support.
Not: an audit by anyone independent of the manufacturer
What it actually means
-

Work out what your building needs
Plain answers to the compliance questions that decide the specification, written by the engineers who do the work. See all guides.
Fire alarm categories: L1 to L5, M, P1 and P2
The letter on your certificate decides how much of the building is watched, and why. What each category covers and who gets to choose it.
Read the guide ComplianceHow often must a fire alarm be serviced?
Two service visits a year under BS 5839-1, plus a weekly test you carry out yourself. What each visit covers and what an inspector asks to see.
Read the guide ComplianceWho is the Responsible Person?
The Fire Safety Order lands the legal duty on a specific person, defined by control rather than job title. How to tell whether that person is you.
Read the guideFire safety questions London businesses ask us
Who is responsible for fire safety in a commercial building?
Under the Regulatory Reform (Fire Safety) Order 2005, the "Responsible Person", usually the employer, owner, landlord or managing agent, must ensure a suitable fire risk assessment is carried out and that fire precautions, including any fire alarm system, are properly maintained. We help Responsible Persons meet those duties with assessments, installation, servicing and certification.
How often should a commercial fire alarm be serviced?
BS 5839-1, the British Standard for commercial fire alarm systems, recommends inspection and servicing by a competent person at least every six months. We recommend six-monthly maintenance visits alongside an annual fire risk assessment review, and we issue a certificate after every service.
How long is a fire alarm certificate valid for?
A fire alarm certificate records the condition of the system at the time of the service, so there is no fixed expiry date. BS 5839-1 recommends servicing at least every six months, and we issue a fresh certificate after every visit. Insurers and inspectors usually want to see a current certificate dated within the last six months.
Can you take over a fire alarm system installed by another company?
Yes, takeover and maintenance of existing systems is one of our core services. It starts with a free survey, then a takeover report, £250 + VAT for up to 15 devices: we test every detector, call point and sounder, report on the condition and compliance of the system, and move it onto a maintenance schedule. You do not need to stay with the company that installed your system.
Are you accredited?
Yes. Flame Shield London is BAFE registered (registration 303184) and an approved Fike and C-TEC installer. Our technicians are fully qualified and BAFE certified. We are the fire safety division of Electro Heating Limited (company no. 12609754), an established London engineering company.
How much does a fire alarm system cost in London?
It depends on the size of the property, the number of devices and whether the system is addressable or conventional, which is why we survey before quoting. The survey and the quote are both free, with no obligation. We explain the price before any work starts.
