Thinking of upgrading to a digital lock on your main door for better security and convenience? If your door is fire-rated, there are some crucial steps you need to know before installing a digital lock. Installing the wrong lock, or doing it incorrectly, can put your home at risk—and even violate safety regulations in Singapore.
Fire rated doors are more than just sturdy doors—they’re life-saving barriers designed to withstand fire for a specific duration. But when you add something like a digital lock, you must ensure it doesn’t compromise the door’s fire-resistant capabilities.
Let’s explore the five must-know steps before installing fire rated digital locks, especially if you live in an HDB, condo, or landed home in Singapore.
1. Check Fire-Rating Compatibility
Before selecting a digital lock, ensure it is specifically designed for use on fire rated doors. The lock should be tested under recognized standards such as SS 332 or EN 1634-1, proving it can withstand high heat without melting or malfunctioning. Only locks labeled as fire-rated should be considered, as using a non-compatible lock may compromise the door’s fire resistance, potentially causing it to fail or even worsen the situation during a fire.
2. Verify CoC Certification and Documentation
From last year March 2024, SCDF mandates that any fire rated digital lock installed on a fire-rated door must come with a valid Certificate of Conformity (CoC). This certificate confirms the lock has passed official fire-resistance testing, either independently or together with the door. Always request the CoC from your supplier, ensuring it specifies the lock model, includes a valid test report from a certified lab, and outlines proper installation guidelines.
Before installing any digital lock, it’s essential to get a professional assessment of your fire-rated door. Key factors like door thickness, frame type, wiring space, and whether the door is a single or double leaf should be checked. Professionals also look for potential conflicts with hinges or handles that could affect the lock’s fit or performance. Every fire-rated door is slightly different, and this step helps avoid costly errors and ensures the installation remains compliant with fire safety standards.
4. Ensure Expert Installation
Installing a digital lock on a fire-rated door isn’t a DIY task—it must be done by trained professionals. Improper drilling or hardware placement can void the door’s fire rating, damage the fire seal, or impact how the door closes in an emergency. Certified installers follow the manufacturer’s template precisely, use the right tools, and take care to protect internal door components. Their expertise ensures the lock functions properly without compromising the door’s ability to resist fire.
5. Functional & Safety Testing After Install
After installing the digital lock on a fire-rated door, it’s essential to carry out basic functional and safety tests to ensure everything is working correctly. Test the lock by entering your PIN or using fingerprint access to confirm smooth locking and unlocking. Simulate a power outage to ensure the backup power source activates as expected. Lastly, check emergency features like the mechanical key override or automatic unlock function to verify they work properly in case of fire or system failure.
