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.

What Some Of Our Customers Say

  • 5 star review  Fuss free from ordering to receiving the smoke detectors. Easy to install as well. Appreciate the after sale customer service.

    5 star review  Ordered the smoke detectors from the BlazeGuard website and received them in good order. The smoke detector is very slim in profile, and can discretely blend into a home like a small spotlight. The alarm is decently loud as well in testing. There are helpful articles on the BlazeGuard website for optimum placing of the detectors, so do read them as well. 🙂

    5 star review  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!

    5 star review  Very responsive, extremely helpful and patient customer service provided instantaneously on whatsapp. It was my first time buying and installing smoke detectors. I was very unsure and had lots of questions about installing something so important in my home. But BlazeGuard guided me through from start to finish. The product has a sleek design, looks better than the other models in the market. Instructions were easy to follow. And the 10-year battery warranty is definitely one of the best offer in the market so far.

What happens when your wifi interconnect smoke detector is triggered on smoke detection?

Your wifi interconnect smoke detector should display like this in standby mode.
Tuya Standby

When your wifi interconnect smoke detector detects smoke and enters alarm mode, you will receive an alert on your Tuya Smart app.
Tuya Alarm
Clicking on Check will bring you to the wifi interconnect smoke detector view.
Tuya Alarm

You can check on past alarm records via the Records button at bottom of above view.

A step by step guide on how to pair your phone to the wifi interconnect smoke detector via Tuya Smart app.

This guide describes the steps to pair your wifi interconnect smoke detector with your mobile phone via Tuya Smart App. Please follow them closely.

You will need the following:

  1. to be at your installation location with your WiFi enabled to do the pairing.
  2. the wifi interconnect smoke detector (it has 2 parts, the smoke detector and the wifi base).
  3. your mobile phone (Android or Apple)
  4. Tuya Smart App
  5. patience!

We recommend you to read through the guide first to get a brief understanding before commencing the pairing. Please pay attention to the parts with this icon and bold in red.

We also have a video for your reference. You can scroll slightly down to refer to the text guide version.

Step-By-Step Guide

  1. Download & install the app TUYA SMART onto your mobile phone. Follow the instructions in the app to setup your account / profile.
  2. Remove the wifi interconnect smoke detector set from the box. There are 2 parts, the actual smoke detector and the wifi base. For the purpose of pairing to your mobile phone, you only need the wifi base.
    Wifi Interconnect Wifi Base
  3. The wifi base comes pre-installed with 2 AA CR14505 batteries. Remove the white battery protector strips by pulling them out. This powers up the wifi base.
  4. Press & hold the multi function button on the wifi base. Release the multi function button after 5 red flashes. You should see the button continuously flashing red now. If not, repeat this step again.
    IMPORTANT: multi function button to be released only after 5 red flashes. If released earlier, it will reset the pairing of this wifi interconnect smoke detectors with other interconnect smoke detectors that we had paired for you prior to delivery to you. In this case, you will also need to re-pair this wifi interconnect smoke detector back into the cluster.
  5. Return to app TUYA SMART and select Home.
  6. Click Tuya Add to add a new device.
  7. Select Add Manually.
  8. Go to category Sensors.
  9. Select Sensor (Wi-Fi) under Sensor category,
  10. Your Wi-Fi SSID (Wi-Fi name) should auto show up. Enter your Wi-Fi password and click Next.
    Tuya Wifi
    • Please note that you must connect to the 2.4GHz Wi-Fi network or the pairing will fail.
    • Most modern routers will have both 5GHz and 2.4GHz Wi-Fi networks. It is highly recommended to have different Wi-Fi names for both networks so that you can accurately choose the 2.4GHz Wi-Fi network name. Please consult your router manual on how to give different Wi-Fi names.
    • If your router auto combines the 5GHz and 2,4GHz Wi-Fi networks together as a single Wi-Fi name, you may not be to pair successfully.
    • This is a limitation of today’s Wi-Fi technologies with TUYA SMART and not a limitation of our smoke detector.
  11. Check the checkbox and click Next at this screen to start pairing.
    Tuya Pairing
  12. Pairing initiates. Be patient. It takes around ONE minute – ONE and HALF minute for the pairing.
    Tuya Start Pairing
    You will see the progress bar moving towards the end of successful pairing.
    Tuya Completing Pairing
  13. You will see the following screen if pairing is successful.
    Tuya Paired Successfully
  14. Click Done to complete the process. You will be returned to app home screen. You should now see your paired wifi interconnect smoke detector in the home screen.
    Tuya Home

If Pairing Fails

  • repeat step 4 to step 12
  • ensure the button at the wifi base is flashing red continuously after you released multi function button after 5 red flashes
  • ensure the Wi-Fi network you are using to do pairing is on your 2.4GHz Wi-Fi network

How To Test Wifi Interconnected Smoke Detector?

If you had purchased interconnected smoke detectors, we would have pre-paired them into cluster(s) according to your preference prior to delivery.

On receipt of your order, you only need to pair your wifi interconnected smoke detector(s) to Tuya Smart app on your mobile. Here’s a guide for you.

To test your wifi interconnected smoke detector, hard press & release the multi function button at the wifi base. Do not press & hold the multi function button for too long as it will trigger a pairing reset (in which case, you will need to re-pair all the interconnected smoke detectors yourself).

Wifi Interconnect Wifi Base
Hard Press & Release Multi Function Button

You should hear the audible alarm from the wifi interconnected smoke detector. If you have already paired the unit to your mobile via Tuya Smart, you should also get a push notification on your mobile.
