Smoke ventilation systems
There are four segments principal to having a reliable smoke control plan; Addlite has put together a short guide listing the key information that will in all likelihood help you pick your smoke vent maintenance requirements. Smoke ventilation products must be building regulation compliant to BS7346: Part 1, 1990, BS9999:2008 BS5588 and (RRO) Regulatory Reform (fire safety) request 2005. Smoke vent control systems are an imperative piece of the fire protection systems in both residential and commercial buildings. Smoke control systems play a signification role in case of fire emergency. When a fire breaks out in the property, the smoke alarm activates the automatic smoke ventilation and opens the AOV unit, which in turn creates so-called “chimney effect”, removing smoke from the building and clearing the escape route. Since the main reason behind fatalities in buildings in fire is not the fire itself, but the smoke. You are required to assure/verify that your AOVs are kept up to date and in unprecedented working condition.
What to check?
- Have the products in the smoke control system been tested to EN12101-2 and CE marked by an independent accredited facility and has a declaration of performance (DoP) been issued?
- Have the products been designed, manufactured, installed and maintained in accordance with the above regulations?
- Does your fire safety contractor approve compliance to the British standard building regulations?
Smoke vent installation
If a specialist is used to install or maintain the smoke ventilation system, they should be able to provide confirmation that the system is suitable, and provides required fire protection.
Smoke vent maintenance
The maintenance of smoke ventilation systems is requested by British Standard BS7346-8, which outlines the need for a minimum of two maintenance appoints annually. The smoke vent maintenance must be carried out by professionally trained engineers. The maintenance engineers must be given access to the original design, have all of the safety and maintenance equipment necessary to inspect the system, including access to replacement equipment should it be required. As an alternative to the EN 12101 system, BS9999 2008 clause V.6.1 details the requirement for maintenance of smoke ventilation systems. Weekly: Test alarm at call points. Check LED markers to ensure backup batteries are in acceptable condition. Check that all hardware is working accurately. Monthly: Test alarm at call points. Check LED markers to ensure reserve batteries are in acceptable condition. Ensure all gear is working accurately. Check the operation of the backup hardware. At restarting the power supply (simulating power failure of mains supply), test the charging of battery. Test the operation of safeguard mechanism. Quarterly: Test alarm at call points. Check LED markers to ensure reserve batteries are in acceptable condition. Ensure all gear is working accurately. Check the operation of the backup hardware. At restarting the power supply (simulating power failure of mains supply), test the charging of battery. Test the operation of safeguard mechanism. Ensure all fans and fueled smoke systems and smoke vents work effectively. Check the smoke shaft systems on each floor in turn.
Advantages of regular smoke vent maintenance
The main advantage of a well-maintained smoke vent life saving system: it saves lives and ensures the security of your property against fire emergencies. Regular smoke vent maintenance increases the lifetime of the smoke control system itself too. To prevent the smoke vents from failing over a period of time, on-going maintenance is a must. Here at Addlite we offer a range of CE marked and EN 12101 AOV smoke vent systems – each with 10 year guarantee.
