Stratification is a largely unknown issue, but affects any high level building. This happens when the thermal ‘lift’ of the smoke is not sufficient to break through a warm layer of air gathered in the roof void. Instead, stratification causes the smoke to form in a ‘cloud’ below the roof level – too low for the ceiling-mounted detection to sense it.
Open protocol and closed protocol fire alarm systems refer to two different approaches in designing and implementing fire alarm systems. These terms primarily relate to fire alarm systems’ communication and compatibility aspects.
Empty commercial properties are highly susceptible to fires, with about sixty incidents daily. Fire alarm monitoring offers early alerts, quickly informing keyholders and fire services.
One of the main problems facing fire detection systems in the UK is exposed/external environments is the unpredictable British weather. Almost every detection system (Smoke, Heat and even some Flame Detectors) can suffer from reduced effectiveness in varying weather conditions. Common issues can include smoke stratification, temperature fluctuations and false alarms through direct sunlight on a detector lens.
Few waste management sites would be able to operate without mobile plant machinery. Being such an operations-critical asset, it’s important to ensure that suitable systems and procedures are in place for their protection.
