A Guide to Safe Installation and Maintenance of Smoke Detectors


Installing smoke detectors in your house is the first defense of staying safe from fire damages. However, these gadgets require proper installation by an expert. They will alert you after the first whiff of smoke and help reduce death risks. 

We have gathered essential information you should know about smoke alarm installation

Let’s get started:

  • Pick the Right Smoke Detectors 

If you live in a house with smoke detectors older than ten years, it’s the right time to install others. Before buying smoke detectors, consult Lexity on reliable smoke sensor alarms. 

A good thing, there are different models, brands, and price points you can pick. However, you need to choose a detector meeting your budget and safety needs. 

  • Use detectors on Every Level of the House

The number of smoke detectors to install will depend on your house layout. Hiring a reliable installation company like Lexity will guide you. 

On the other hand, the minimum number of pieces to install at each level is one. You can install each at every sleeping space, attics, and basement. 

  • Install in Central Locations

You don’t have to spend nights without using smoke detectors. Ensure you consult Lexity and install as soon as possible. 

  • Test Smoke Detectors

Once you have installed smoke alarms and they are ready, test to check whether they are working. Press the button of all alarms individually. Ensure everyone living in the house will recognize the sound. 

The first step will help discuss the evacuation plan, routes, and meeting points outside in case of a fire emergency. 

  • Perform Power Tests Monthly 

Some smart detectors usually self-test. However, it is advisable you manually test the detectors at least monthly. If you want to run the test, push the detectors button to verify the sensor is working, and the alarm sounds are at optimal volume.

Suppose there are alarm buttons you can’t reach in the house; take precautions while climbing to test them. Avoid using a chair but a sturdy stepladder. Perform the task in the presence of another family member.

  • Replace Non-Hardwired Detector Battery Annually 

When smoke detectors run on battery, you don’t wait until the batteries are dead for you to charge them. The right thing is setting annual battery replacement. Sometimes, picking an actual date to replace the battery is easier.

In addition, refer to your manufacturer’s guide on when to replace batteries. 

  • Clean Smoke Detectors Once Per Year

Pollutants and dust can impede your fire alarm performance. You should always try to keep the detectors clean. Occasionally, light dust using a dry rag to remove exterior dust. However, deeper cleaning is recommended annually.  

When thorough cleaning, remove the device from the ceiling or wall and gently remove the external casing. Clean the device carefully for collected dust with a vacuum attachment. You can use a dry cloth or compressed air – avoid using cleaners or liquid sprays. 


Fire safety is an essential component to have at home. We hope you never experience a fire in your home, but it’s crucial to be prepared. The above steps will guide you in installing and maintaining your fire and smoke alarms.
