When is a home fire alarm device required?
The Singapore Civil Defence Force (SCDF) describes a home fire alarm device as an automatic smoke or heat detector that sounds an alarm to give early warning of a fire. Under SCDF's rules, HFADs are mandatory from 2018 for new homes, and for existing homes carrying out fire safety works with plans submitted to SCDF or another agency.
Fire safety works are addition and alteration works. SCDF gives examples such as:
- Installing or relocating fire doors
- Roofing over open balconies
- Works on walls that separate your home from common areas
If you live in an existing home and are not doing such works, an HFAD is not mandatory, although SCDF strongly encourages owners to install one. The HFAD rules for HDB resale flats are the same: required with fire safety works, strongly encouraged without them.
If you are not sure whether your renovation counts, ask your contractor whether any planned works involve fire doors, open balconies or walls that separate your flat from common areas.
Where to place it
SCDF's FAQ sets out placement under the Fire Code for new homes and homes doing fire safety works. Single-storey homes, such as HDB flats and condo apartments, need at least 1 HFAD, which must be a smoke detector, along the circulation area or escape route, such as the living room or corridor. Multi-storey homes need at least 1 on each storey.
Circulation areas do not include bedrooms, storerooms or bathrooms. So a smoke detector in an HDB flat goes in the living room or corridor rather than a bedroom. You can add more units for enhanced protection.
The same SCDF FAQ says cooking or burning religious items generally does not set off an HFAD unless it is very close. If false alarms happen often, move the HFAD away from cooking stoves or altars, or contact the supplier.
Choosing a device
When you buy an HFAD, SCDF's FAQ lists the features to look for:
- Smoke detection, on its own or in a multi-sensor detector
- Indicator lights
- A temporary silence or reset feature
- A test button
- A sounder
- Battery power, with a battery that lasts at least 10 years and shows a low-battery indication
SCDF also recommends units with a built-in battery with a 10-year life span.
If a family member is a senior, the Enhancement for Active Seniors (EASE) programme from HDB includes an HFAD in the living room, or 2 for an Executive Maisonette. Under EASE (Direct Application), Singapore Citizen households in sold flats and Registered Tenants in rental flats can apply if a family member is 65 or older, or aged 60 to 64 and needs help with at least 1 Activity of Daily Living. HDB lists the owner's share by flat type and has an e-calculator. See our HDB EASE programme guide for how to apply.
How to test and maintain it
SCDF's FAQ asks you to test your HFAD regularly and replace it at the end-of-life date the manufacturer recommends. These four steps cover the routine:
- Press the test button. Press it and listen for the alarm to sound.
- Check the indicator light. Look at the indicator light and compare what it shows with the manufacturer's manual.
- Replace dry-cell batteries. If your unit runs on dry-cell batteries, replace them at least once a year. Units with a built-in battery last around 10 years.
- Replace the device at end of life. Swap the whole unit at the end-of-life date the manufacturer recommends.
The SCDF FAQ also says owners and occupiers are responsible for keeping fire safety provisions in the home, including HFADs, in good working condition. If you rent, ask your landlord who will change the batteries and who will replace the unit when it reaches its end-of-life date.
When it sounds
SCDF's FAQ sets out what to do when an HFAD sounds. First, check for smoke or fire. If there is a small fire, use a fire extinguisher. If the fire spreads quickly, get everyone out of the flat and call 995. If there is no smoke or fire, it may be a false alarm. Once you are sure there is no emergency, reset the unit with its Silence/Reset button.

Find the right serviceInstalling one
SCDF's FAQ says no Qualified Person needs to submit plans for a voluntary HFAD installation. Mount the unit as the manufacturer's instructions say.
If you want a unit wired into your home's electrical installation, that is electrical work. The Energy Market Authority (EMA) says electrical work at home should be carried out or supervised by a Licensed Electrical Worker (LEW). EMA says electrical work in an HDB flat needs a Licensed Electrician, the class of LEW approved for loads of up to 45kVA. Check the worker's licence card before any work starts, as EMA advises.

Questions
Is a fire alarm compulsory in my resale HDB flat?
Not unless you carry out fire safety works. SCDF makes HFADs mandatory for new homes and for existing homes doing fire safety works with plans submitted, such as relocating fire doors. A resale flat is an existing home, so otherwise it is your choice, although SCDF strongly encourages owners to install one.
Is a smoke detector better than a heat detector?
Can I put the alarm in the kitchen?
Not near the cooking stove. SCDF's FAQ says that if false alarms are frequent, you should move the HFAD away from cooking stoves or altars. Place it along the escape route instead, such as the living room or corridor, which is where SCDF's placement rules put the smoke detector.
How often should I test it?
Regularly. SCDF's FAQ says to test your HFAD regularly, so press the test button and listen for the alarm. Check the manufacturer's manual for any testing schedule it gives. Replace dry-cell batteries at least once a year, and replace the unit at the end-of-life date the manufacturer recommends.
Does SCDF approve fire alarm brands?
What should I do if it keeps beeping?
Check for the low-battery warning, then replace the battery or the device as the manufacturer instructs. SCDF's FAQ lists a low-battery indication among the features to look for. Dry-cell batteries need replacing at least once a year, while built-in battery units last around 10 years. If the full alarm sounds, check for smoke or fire first.
