Routine testing of systems


Fire Alarm systems should be regularly tested and serviced. BS5839 Part 1 makes the following recommendations:

Daily


i) Check that the panel indicates normal operation. If not, record any fault indicated in the event log and report the fault to a responsible person.
ii) Check that any fault recorded for the previous day has received attention.

Weekly


i) Operate a manual call point or smoke detector to ensure the system operates properly. Each week a different detector should be checked.
ii) Check that the sounders have operated and then reset the system.
iii) Check the battery connections.
iv) Complete the event log with details of date, time, trigger device tested and enter "Routine Weekly Test" the "Action Required" and reported to a responsible person.

Testing Smoke DetecterQuarterly


i) Check entries in the log book and take any necessary action.
ii) Examine the batteries and their connections.
iii) Operate a manual call point or smoke detector to ensure the system operates properly, checking that all sounders are operating.
iv) Check that all functions of the alarm control panel operate by simulating fault conditions.
v) Visually check that structural alterations have not been made that could have an effect on the siting of detectors and other trigger devices.
vi) Complete the event log with details of date, time, trigger device tested and "Quarterly Test" in the event section. Any defects or alterations to equipment should also be entered.

Annually


i) Carry out an inspection as detailed for the quarterly inspection.
ii) Every detector should be tested in situ.
iii) All cable fittings and equipment should be checked to ensure that they are secure and undamaged.

The three most important things to do before considering any aspects of a fire detection and alarm system are:

i) Consult your local Fire Prevention Officer — he will be pleased to advise you on what you require in accordance with the new Fire Safety order 2005 and give you information on compliance with any by-laws, and provide information specific to your building.

ii) Study in detail British Standard BS5839 Pt 1 — Code of Practice for the design, installation and maintenance of fire alarm systems in buildings. The document provides an in-depth guide to the requirements of systems in most types of buildings.

iii) Deal with a reputable equipment supplier — most good manufacturers of fire detection and alarm equipment will be pleased to provide advice on the design of systems to meet the requirements of BS5839 Pt 1.
A team of project engineering experts located throughout the UK, provide this service on a local basis, without obligation.

Checklist for equipment selection:


a) Smoke and heat detectors
Always ensure detectors are correctly spaced, and the floor area coverage given in BS5839 Pt 1 is not exceeded.

Choose the correct detector type. With more and more flame retardant treatments used in building materials, furnishings and furniture, photoelectric smoke detectors now tend to be by far the most popular form of smoke detector.

Make allowance for any obstruction — when siting detectors, beams, partitions etc must be taken into account. Again BS5839 gives clear instructions.

Always consider environmental conditions — most smoke detectors will be prone to unwanted alarms if sited in areas of high air movement, or where steam or vapours from kitchens, laundries or exhaust fumes are likely to be present. In areas unsuitable for smoke detectors, heat detectors may provide adequate protection.

b) Manual call points
Manual call points (break glass units) should be located at all ground floor exits from the building, close to and usually on the opening side of the door frame.
They should be conspicuous and mounted 1.4m above floor level.
The British Standard requires manual call points to be mounted on stairwell landings.

Occupants should not have to travel more than 30 metres within a building before encountering a manual call point. This maximum distance may need to be reduced if occupants are elderly or infirm.

c) Control panels
Always locate the central fire alarm control panel in a low fire risk area.
Its location must be easily accessible to the local Fire Brigade in cases of emergency.
The area must also be well lit. The provision of emergency lighting units may therefore be necessary.

d) Sounders
Alarm sounders must be all the same type i.e. all provide the same sound.
Ensure correct sound levels are maintained in all parts of the building.
A maximum of one door or wall between sounders and any room.
Many small sounders give better sound distribution than a few large ones.
However small the fire alarm system, a minimum of two sounders is required.

Choose a Fire Alarm System from Fire Protection Services Ltd and you can be sure that it will comply with current requirements, hardware and installation is of the highest quality and that the 'protocol' is Open, enabling you to change your service provider as you require.
