You Hate Changing Batteries, So Do We

10 Years of Continuous Power

Powered by lithium battery, our smoke detector provides 10 years of continuous smoke detection, every day of the year.

Lithium Battery

Say Bye To False Alarms

Carefully Calibrated Photoelectric Sensor

Not all photoelectric smoke detectors have the same level of sensitivity. Our smoke detectors are subjected to different household environment and smoke density to get the best balance of sensitivity, in order to ensure that we only alert you when there is a real fire threat.

Photoelectric Chamber

Anti Dust Design

We also eliminate false alarms with a revolutionary anti-dust design around the photoelectric sensor chamber, blocking out dust particles which may otherwise trigger an alarm.

No Ceiling Too High To Reach

There should not be a need to have to use a ladder / stool whenever you want to test the smoke detector. Testing is made easy with our big test button, strategically located at the front of the smoke detector. Doesn't matter if it's HDB @ 2.6m, or Condominium @ 3 - 3.6m, or even Landed with ceiling height upwards of 3.6m. All you need is just an extendable pole.

Heights of Different Homes

Hassle Free Installation

No mess, no hassle with double-sided industrial grade 3M PE foam tape. Simply peel off the protective layer and stick our smoke detector up on the ceiling. Of course, if you want to go the traditional way, that is fine as well with our provided wall anchor plugs and screws.

How To Pair Our Interconnect Smoke Detectors?





Many Frequently Asked Questions Answered

I see you have both interconnect and standalone models. What is the difference between these 2 models?

The main difference is interconnect smoke detectors will all sound when one of them is triggered. This is especially important in multi storey homes such as landed, penthouses, maisonettes or single storey homes such as a bungalow. The intent here is to alert the occupants of potential fire threats who may not be near that fire threat.

An example would be when every one is sound asleep in the 2nd storey when a potential fire threat occurs in ground storey kitchen. If a standalone has been installed, while the standalone in the kitchen may be triggered, the chance of that waking her occupants up on 2nd storey, in air-conditioned room ain't high. When the toxic smoke builds up to 2nd storey and trigger off the detectors there, it may be too late for the occupants to escape as the 1st storey is already filled with toxic smoke. If interconnect have been installed, when the detector in kitchen is triggered, all interconnect detectors will sound alarm. This has a much better chance of waking her occupants and in event of a real fire threat, provides precious minutes for them to escape.

Is your detector a photoelectric or ionization or both?

Both our standalone and interconnect smoke detectors are photoelectric. Photoelectric responds faster to smouldering fires, which are typical of fires occurring in homes. Think of overcharged electrical devices, overloaded power points where smoke will start to form around the fire threat, followed by denser white smoke, and eventually with very dense black smoke (as plastic melt) before a flame occurs. 

This is in contrast to fast flaming fires such as from an explosion, where an ionization smoke detector will be more effective.

We do not carry combi (photoelectric + ionization) smoke detectors as we believe the disadvantages of each cancel out the advantage of the other. This may result in less effective detection of all types of fire and potentially cause more false alarms.

Do you provide installation services?

We do not provide installation services, but we can advise you on optimum locations to install the smoke detectors if you can share your floorplan / pictures with us via whatsapp @ 8815 8752 or email to

Installation is also very easy with our 3M double sided PE foam tape. No drilling is required.

Where should I install the smoke detector?

This is a very big topic by itself. We will try to summarize it here. Smoke detectors should be installed along the path of escape out of homes. Why? Because the intent of smoke detectors is to give you early warning on potential fire threats, so that you have ample time to escape if the fire can't be put out by yourself. It will be useless if by the time the smoke detectors sound out alarm, your escape path out of your home is no longer viable.

Presence of fire is an obvious reason. However, very often the escape path may be made non-viable because of smoke.

  • You may be surprised that many fire casualties are from smoke (inhalation), rather than the fire itself.
  • You will also not expect by the time dense smoke has built up, the temperate of the smoke can be upwards of 80 degrees celsius. Most cannot endure such heat.
  • Smoke from household items burning are extremely toxic. Breathing in too much can make one unconscious. Putting aside the toxicity of the smoke, breathing in too much smoke deprives your brain of oxygen, which will result in yourself rendered unconscious. Once one is unconscious, how does one escape?
  • Smoke makes one loses directional sense. There have been many incidents when fire casualties were found within metres of their main door after the fire was put out. Most of such casualties were unable to find their main door to escape in the midst of the dense smoke. It is also this reason that as part of the fire escape practicing, it is recommended that one blindfolds oneself to try to navigate from room to main door.

Hope that you now have a better understanding of why smoke detectors should be installed along your escape path out of your home. In addition, most of us are living in flats & apartments, which often only has 1 escape option - through the main door. If this escape option is rendered non-viable, the situation is going to get worse quickly. On average, it takes only 3 minutes for a fire to occupy the entire house once fire starts to burn.

There is also the concept of dead air space that we need to avoid. Essentially, this is the air space that's ~10cm from any corner. It's called dead because smoke will never reach these areas due to physics of air. Installing a smoke detector there guarantees your detector will never ring. You can read more about dead air space in this link.

There are also certain locations with our homes that we need to avoid as they are either too dusty, too steamy or too breezy, such as kitchens, bathrooms. You can read more about these places in this link.

One question in your mind now is likely to be "Yea, I understand. But this still doesn't really tell me where to install". 

Yes, we are aware of that. The reason why we explain all the above is to let you understand the important fact (if you cannot understand most of the above) that smoke detectors should be installed in correct locations so that they can do what they do best.

So the best way to help answer this question is if you can share your floorplan / pictures with us via whatsapp @ 8815 8752 or email to,  so that we can advise you on optimum locations.

I do lots of heavy cooking at home. Will it cause false alarm?

We do not recommend installation of smoke detectors in the kitchen due to:

  1. smoke from cooking, which can cause false alarms, especially if installed within 1 metre of the kitchen stove. 
  2. oil & grease can easily build up around the smoke detector, which would then require more frequent cleaning.

Instead we would recommend to install just outside the kitchen if need be as it will still be a good location to detect smoke coming from kitchen without the false alarms and regular cleaning.

Does your smoke detector detect gas leak?

No, our smoke detectors are purely smoke detectors. As gas isn't made up of smoke particles, a gas leak will not trigger our smoke detectors. If you need to detect gas leak, you will need to invest in a separate gas detector.

I smoke at home. Will it cause false alarm?

Unless you are smoking directly at the smoke detector or heavily under the smoke detector, our smoke detector is unlikely to be falsely triggered. 

I burn joss/incense sticks at home. Will it cause false alarm?

We recommend to install our smoke detector at least 1 metre away from joss / incense sticks burning to avoid false alarms. This also avoid the need for more regular cleaning of the smoke detector.

Can I install in the bathroom?

We do not recommend installation in the bathroom due to its high humidity, which will damage the internal circuitry, causing it to fail. Furthermore, steam from a hot shower will often trigger the alarm.

If the bathroom is ensuite, we recommend installation more than 1 metre away from the entrance of the bathroom.

Can I install near my aircon / fan?

We do not recommend installing our smoke detectors within 1 metre to the aircon/fan. We also do not recommend installing in the direction of the wind / draft as smoke may be blown away by the draft, causing our detectors not able to detect smoke.

Should I install smoke detector at the yard? I have a dryer there.

We generally do not recommend installing in open spaces as the chance of false alarm is significantly higher with environment dust / fine particles blown into the smoke detection chamber. 

If the concern is about washing machine / dryer catching fire, you will have to find a location that is "less exposed" to avoid false alarms. Please send us pictures of the yard via whatsapp @ 8815 8752 or email to for us to better advise you.

Will your smoke detector have false alarm?

Our smoke detectors are anti-dust by design. What this means is the smoke detection chamber is engineered to minimize any other particles other than smoke from entering the chamber. That said, a smoke particle, while very small at <1mm in diameter, isn't the smallest particle, so any other particles smaller than a smoke particle may still enter the chamber, triggering a false alarm. Example of such smaller particles include face powder, talcum dust, corn starch to name a few.

Long story short, we cannot 100% guarantee that our smoke detectors will not have false alarms. But we have put in much research and engineering efforts to mitigate false alarms while not affecting its ability to detect smoke.

What should I do when the smoke detector starts ringing?

First of all, you have to assume it's a true alarm and you should investigate immediate surrounding area for any potential fire threats. In the event of a real fire threat, if you can put out the threat (eg fire blanket or fire extinguisher), do go ahead, else you should quickly execute your fire escape plan and get your family to safety.

If you had done your checks and confirmed that it's a false alarm, you can silence our detectors by pressing the silence / hush (which is the test) button.

Our smoke detectors come with easy to reach and big silence / hush button, so you do not need to get a stool / ladder. You can simply use an extended pole to reach for the silence / hush button. 

Upon pressing, the alarm will be deactivated for 9-10 minutes. Should it detect smoke again after 9-10 minutes, it will start ringing again.

If you are certain the detector is faulty, you should contact us via whatsapp @ 8815 8752 or email to and we will advise your accordingly. 

What should I do if the Low Battery warning light shows up?

Our smoke detectors are powered by lithium battery which has sufficient power for 10 years.

In the event the low battery warning light appears within the 1st 3 years, you can reach out to us via whatsapp @ 8815 8752 or email to for an exchange. 

If you have qualified for the 10 years battery warranty, you are eligible for exchange if the low battery warning light appears in the 1st 10 years.

Please refer to 10 years battery warranty FAQ below for more details.

Where should I keep the fire blanket if I only have 1 piece?

Ideally you would want to have 1 fire blanket in each room, living room and kitchen as you can't predict where the fire may start. But if you only have 1 piece, we would recommend your bedroom as

  1. if the fire starts in kitchen, you can still run to your bedroom to get the fire blanket to try to put out the kitchen fire, assuming fire is still small (eg fire in a pot).
  2. if the fire occurs at night when every one is sleeping, it's going to be very hard for you to make your way to any part of the home to get the fire blanket. Plus if the fire occurs outside your bedroom, there could be so much dense smoke built up that it may be near impossible to go to anywhere.
  3. following up on above point, it will be easier for you to get blanket from your bedroom to wrap around you/kids if any to try to escape out of home.

Does your smoke detector require cleaning? If yes, how?

All smoke detectors will require regularly cleaning. The main difference lies in how easy and how frequent.

Our smoke detectors are anti-dust by design, so they require less efforts to clean. You simply need to vacuum or a cloth to wipe to exterior. Because our smoke detectors do not require battery replacement, there is no need (and you should not attempt) to open up the detector to clean the inside.

Once a month cleaning is more than sufficient for our smoke detectors.

Can I test the smoke detector with real smoke?

DO NOT EVER DO THAT! When you burn something to produce smoke to test, carbon particles (natural byproduct of burning) will also enter the smoke detection chamber and stay there permanently, either affecting its ability to detect smoke or having more false alarms moving forward.

This is also the reason if the detector has been triggered by a real fire threat, you are required to replace and not reuse, regardless how visually un-damaged it may look. Refer to FAQ "Do I need to replace the detector?".

If you really must test with "smoke", you will need to use an industrial smoke tester. Reach out to us via whatsapp @ 8815 8752 or email to if you want to know more about this smoke tester.

I was told that I should test the smoke detector regularly. Why?

There are 2 main purposes of testing:

  1. To be familiar with how the alarm of your smoke detector sounds like. It's the same reason why the Public Warning System in Singapore is activated at least twice a year.  You may even want to  practice your fire escape plan with family during this time. 
  2. To ensure the detector is still powered up. While our smoke detectors will have low battery warning light and audio beep, one may not see the warning light if it's installed in a more remote location. Eventually the audio beep will also stop as battery runs out of power. At this point, the detector is non-operational.

We recommend testing once a week. It takes you less than a minute to test it. With an easy to reach and big test button in our smoke detectors, you do not need to get a stool / ladder to reach our detectors to test. You can simply use an extended pole to reach for the test button.

For clarity, the above testing (via a test button) is to verify that the circuitry is functional. It DOES NOT test if the smoke detection chamber is functional. To test the smoke detection chamber, you will need to use an industrial smoke tester. Reach out to us via whatsapp @ 8815 8752 or email to if you want to know more about this smoke tester. 

NEVER NEVER test the smoke detector with real smoke.

Do I need to replace the detector?

The circuitry and mechanism within our smoke detectors are designed to last for 10 years. Even the detector appears to be in working condition after 10 years, we highly recommend that you replace a new one. If you have purchased our smoke detector, we will email you when your 10th year is reaching to remind you. You do not have to remember it yourself.

The other case will be the detector has been triggered by a real fire threat. The reason is carbon particles within the smoke would have accumulated within the smoke detection chamber. Even if the detector isn't destroyed or visually damaged in any shape or form, it may no longer be able to effectively detect smoke. This puts your entire family into danger!

    Bought two sets of the interconnect HFAD. Truly surprised with the level of service that I received from the seller. Seller connected all the HFAD before sending it out. I also received advice for where to set it up. Excellent after sale service.

  10. Desiree Huang (verified owner)

    We needed a linked smoke alarm as part of the SCDF requirement for TOP and. This product is the best value for money that I have found in Singapore and works well.
    More importantly, the service was excellent. Not only was the response quick, CJ was extremely helpful in his recommendations and sending me the necessary documentation.
    One of the units we had installed seemed to have a problem and CJ walked us through a troubleshooting process. When that didn’t resolve the problem, without hesitation, he changed the piece and relinked the replacement with the other units.
    I would definitely recommend Blazeguard and their service!
