Fire Rated Lock

Singapore's SCDF regulations require that HDB main doors are fire-rated, and any hardware fitted to them must be installed in a way that does not compromise that rating. Kaadas digital locks are specifically designed for compatibility with Singapore's standard fire-rated wooden main doors. Our installation team verifies compliance before every fitting, included free with your purchase.

Yes, provided the lock is compatible with fire-rated door construction and the installation is done correctly. Kaadas locks are designed to replace the existing mortise lock on a standard HDB wooden fire-rated door without significant structural modification to the door structure. A minimum door thickness of 40mm is required, which most standard HDB main doors already meet.

A Certificate of Conformity (COC) is a document confirming a fire door or its components meet Singapore's fire safety standards. COCs are typically issued for the door itself by the door manufacturer or supplier. Kaadas digital locks are designed to be installed on compliant fire-rated doors without voiding their certification. If you have questions about your door's existing COC, our team can advise during the pre-installation assessment.

All Kaadas digital locks include a mechanical key override that functions independently of battery, power, or electronics. In a fire or emergency, the door can always be opened with the physical key regardless of power or electronic conditions. The lock mechanism is designed to not interfere with the fire door's ability to contain fire and support safe evacuation.

Kaadas digital locks require a minimum door thickness of 40mm. This is the standard specification for HDB fire-rated wooden main doors in Singapore, and most doors comfortably meet or exceed this. Our installation team measures your door on arrival and confirms compatibility before proceeding with the installation.

Not when installed correctly by a trained technician. Kaadas locks are designed to replace the existing mortise hardware without any additional structural modification to the door. Our installers are specifically trained for Singapore's HDB door specifications and do not make structural modifications that would affect the door’s fire rating.

Most Singapore condo main doors are also fire-rated wooden doors and follow similar construction standards to HDB doors. Kaadas locks are compatible with these doors. Some condominiums have specific rules about lock modifications, check with your management corporation (MCST) if unsure. Our team can help assess your condo door and advise on any specific requirements.
