Can I Install a Digital Lock On an HDB Fire-Rated Door? Mistakes to Avoid

Digital door locks add significant convenience and functionality to any door they are mounted on, giving you plenty of control and extra security features over how you enter your property or a specific room. While adding a digital door lock can be valuable to help you secure your property, adding one to a fire-rated door will require some additional forethought. This decision is based on current regulations and the need for greater fire safety, especially as recent statistics show that stronger fire safety measures are necessary to safeguard the well-being of Singaporeans.

These doors are reinforced to withstand a blazing fire for a specified amount of time, giving you time to escape before the fire quickly becomes uncontrollable. Fire-rated doors can help compartmentalise fires so they do not spread to other areas, ensuring that others can evacuate while allowing firefighters to contain the blaze.

A fire-rated door comprises various materials that meet required specifications, enabling them to withstand high temperatures and provide the door with the fire resistance it needs. They will need to meet many stringent standards that ensure they can perform strongly when a fire breaks out, as that can mean the difference between life and death.

Additional requirements may also need to be fulfilled for fire-rated doors under specific circumstances, including the following:

• All fire-rated doors should have an automatic self-closing device to close a door “from any angle and against any latch fitted to the door.” This device is unnecessary if a “bolted door leaf of a two-leaf door” serves as an “entrance door to a residential unit under PG II.”
• Any “fitted in an opening which is provided as a means of escape” should be accessible without needing a “key, tool, special knowledge or effort for operation from the inside of the building.”
• Fire-rated door hinges also need to comply with specific regulations on approved types.

Similarly, digital door locks will also need to meet equally strict standards to ensure they provide high-quality security and can safeguard your well-being when a fire breaks out.

Per new regulations introduced in 2024, you will need to select a digital door lock certified with a Certificate of Conformity to SS 332/ EN 1634-1 issued by a local certification body. Not only that, but a digital door lock must also include a mechanical failsafe to ensure the lock can still be opened from inside (or outside) the home, even when there is no power. This feature ensures that the lock does not prevent your escape if a fire occurs.

Like a fire-rated door, a digital door lock should also have a fire rating that ensures it can withstand a blaze for some time so that you can still access the door and make your way to safety. A fire rating typically denotes how long something can hold back a fire and smoke and typically rates in minutes or hours; the higher the fire rating, the longer it can keep fire and smoke at bay.

Some digital door locks come with valuable features that help to enhance fire safety and awareness, such as a built-in sensor that can detect sudden temperature changes that may indicate a fire. When the sensor detects that temperature spike, it automatically disengages the lock so you can quickly evacuate immediately. These features are essential to your well-being as they do not impede your evacuation when it is necessary.

Various key factors should be prioritised when mounting a digital door lock to a fire-rated door to ensure that it can work optimally and ensure your safety at all times.

There is no minimum” fire rating setting for any fire-rated door or digital door lock, but not all digital door locks are designed with a fire rating in mind. As such, many homeowners may purchase an affordable digital door lock that is not fire-rated nor has safety features that can help (like the aforementioned temperature sensor). That can complicate matters, as non-fire-rated digital door locks can be problematic when a fire breaks out.

For example, if power has been lost, you cannot disengage the digital door lock, which can mean you are trapped with no way to open the door. There is also the concern that the non-fire-rated digital door lock’s mechanism may have melted due to the fire’s intense heat, which again spells trouble.

As such, you should always check if a digital door lock model you are interested in has a Certificate of Conformity (CoC) issued by the three relevant certification bodies (Element Testing Services (S) Pte Ltd, SETSCO Services Pte Ltd, and TUV SUD PSB Pte Ltd). The CoC will provide all the relevant details, including their fire rating.

Modifications to any fixture in your home can quickly go awry if you make changes that may compromise your property’s safety without you realising it. Besides purchasing a non-fire-rated digital door lock, you may have purchased one that may not be compatible with your fire-rated door due to mechanism incompatibilities or something else entirely. If you continue with this decision, you can ultimately end up with problems should a fire suddenly break out, including the inability to operate the digital door lock due to power loss or something else.

Again, it helps to buy a digital door lock with a COC to ensure that it meets the relevant fire safety regulations without hindering your safety.

Even with a fire-rated digital door lock, improper installation can instantly turn a very effective lock into a liability. Whether due to poor placement, a mistake in its programming, or something that inadvertently affects or impairs the lock’s functionality, it can significantly reduce the digital door lock’s effectiveness and compromise the fire-rated door. The trouble is that you may not necessarily know if a digital door lock was poorly installed at a glance, which will become a significant problem in the event of a fire.

If you have any doubts, contact a professional door lock technician who can check your digital door lock’s placement and overall installation to ensure it is properly installed and will not compromise the fire-rated door’s performance or functionality. Regular checks may also be beneficial for maintaining long-term functionality.

If you decide to invest in a digital door lock for your fire-rated door, ignoring the need for a professional assessment before the installation can also pose problems later on. For one, a professional can help you determine whether a particular digital door lock model is compatible with your fire-rated door. They can provide you with valuable information beforehand to ensure you know what features you should be looking for so you will not have to look up various reviews to determine which would fit your needs well. They can also provide professional installation to give you peace of mind and guaranteed safety with the right fire-rated digital door lock for your property.

In some cases, digital door locks may be advertised as having a fire rating and valuable features that can protect you when a fire breaks out, and the lower entry cost may make it seem like a worthwhile purchase compared to other digital door locks that may cost more for their fire rating. However, these may not have any of these advertised features or a CoC from the relevant accreditation bodies, meaning they falsely advertise the digital door lock’s capabilities. If you do not do your due diligence, that can prove to be a problem later on when it fails to safeguard you in the event of a fire.

It is best to buy only from a well-rated supplier of digital door locks that can provide you with the relevant details, including the CoC, for any fire-rated digital door lock you may be interested in.
