Digital Locksets on Fire-rated Doors
Digital Locksets on Fire-rated Doors

Digital locksets (“DDL”) installed on fire-rated doors (“fire doors”) must be certified for their fire performance. The DDL can be certified together with the fire door or certified individually on its own.  This requirement applies to DDL installed onto fire doors from 1 Mar 2024.

Rationale for DDL Certification

Fire doors are used to minimise fire spread within buildings. These doors and their hardware, such as DDL,  are certified to ensure they meet fire safety requirements. If uncertified hardware is installed on a fire door, this may affect the door’s ability to minimise fire spread.

Some types of digital locksets
Identifying Fire Doors
To know whether a door is a fire door, you may check for serial labels pasted near the hinges of the door or door frame. The label would state the fire rating of the door, e.g., 30-min fire rating, 60-min fire rating, etc. If unsure whether the door is a fire door, you may also check with HDB (for public homes) or your MCST (for strata-titled properties such as a condominium). Please refer to this link for serial label samples.

 

How to Check for DDL Certification

For DDLs which are certified together with the door, you may ask the door supplier to show you that the brand and model of the DDL is listed in the fire door’s Certificate of Conformity (“CoC”) (usually in the Appendix). This is usually for DDLs which were originally supplied with the fire door.

If you are a consumer (homeowner/premises owner) who wishes to install a DDL for an existing fire door, you can look for DDLs which are individually certified for their fire resistance. You may ask the supplier to show you the product’s CoC. Such CoCs are issued by product certification bodies. Currently, only three certification bodies (see samples below) can issue CoCs for DDL.

Key Product Information in the Certificate

You may ask the supplier to show you this information in their CoC:

  1. Brand and model – the brand and model printed on the CoC matches the brand and model of the DDL you want to buy.

  2. Product details – the product’s fire-rating (in minutes) must be at least as high as the fire door’s. For example, for a 30-min fire door, you can use DDL certified with fire rating of 30-min, 60-min or 120-min. Product details should also state mechanical fail-safe feature (so that you can still unlock the DDL to leave the house, even if the battery dies).
  3. Test standards – the product is certified to SS 332, or EN 1634-1.

Uncertified DDLs Installed Before 1 Mar 2024

DDL in the market are generally robust (e.g., with metal backplate and lockcase to prevent fire from burning through the door early). However, for fire doors in residential premises (which are typically 30-min or 60-min fire-rated) with uncertified DDL installed before 1 March 2024, homeowners are encouraged to replace it with a certified DDL.
