In 2018, Singapore encountered 3,885 fire outbreaks, with an increase in fires in non-residential and non-building premises. Efficient, effective and early detection of fires via electrical fire alarm systems can save thousands of lives and properties. The revised SS 645:2019, formerly known as CP10, provides requirements on the installation and servicing of electrical fire alarm systems in buildings. It covers fire alarm systems using manual call points, heat detectors, smoke detectors, flame detectors and video image fire detectors.Given the destructive nature of fires, it is crucial for professional engineers, contractors and architects to understand

The SS 638 : 2018 (formerly CP 5) and SS 650 : 2019 Parts 1&2 (formerly CP 88 Parts 1&2) are mandatory requirements under the Electricity (Electrical Installations) Regulations in Singapore. The standards set out the safety rules and wiring practices that shall be observed in carrying out low voltage design, operation and maintenance works by persons or parties involved, such as licensed electrical workers, electrical contractors, consultant firms, testing companies, supervisors and workers engaged in electrical wiring and fitting works, etc. The aim is to ensure safety, especially from electric shock and fire in the use of electricity. The implementation of these standards has helped to reduce the number of electrocution and fire incidents in the use of electricity occurring over the years.
