The HFAD is an automatic smoke detector installed on the ceiling that will emit an audible alarm when smoke is detected. It is provided as a fire safety feature for your home.
When you renovate your home, you are advised to place a temporary cover, eg a plastic sheet, over the HFAD to minimise the entry of dust.
Remember to remove the temporary cover after renovation.
To find out more about the HFAD installation, you may refer to SCDF website at www.scdf.gov.sg/HFAD.
For maintenance tips on the HFAD, please refer to the user manual provided inside your flat.
