Smoke and Carbon Monoxide Detector FAQ

Smoke and Carbon Monoxide detectors or sensors are one of the simplest systems that exist in fire and gas protection.

An optical smoke detector is activated as soon as the built-in lens detects an abnormal level of visible smoke in the air. Then it emits an acoustic signal. It is a useful tool for your peace of mind and that of your family when you are at home, even at night when the sound would wake us up in the presence of smoke.

If you are planning to install this incredibly useful device in your home, office, or warehouse, check out the following Frequently Asked Questions (FAQs):

What Is a Smoke and Carbon Monoxide Detector?

A combination of Carbon Monoxide and Smoke detector has sense technology that works together to detect fires. Also, it detects tasteless, colorless, and odorless Carbon Monoxide which is also called CO – It is the silent killer. So, it is very important to install it in your home and/or office.

How Does Smoke and Carbon Monoxide Detector Work?

There are different types of Smoke and CO sensors, with different characteristics and different functions. All detectors employ a new generation of approved electrochemical sensors.

This type of sensor is low power consumption, making it suitable for use in battery-powered detectors. The electrochemical sensor works by catalytic action giving a response directly proportional to the amount of CO present. It has a minimum of 5 years of useful life, with good immunity against polluting gases.

As their name suggests, detect the presence of gas in the air. When there is a certain concentration, the device emits an acoustic and/or visual signal.

Thus, it warns if there is a leak of any type of gas (propane, butane, natural gas, or carbon monoxide –produced by poor combustion of wood stoves, gas, or fireplaces-).

Some models allow connection to the gas system so that the detector cuts the supply if the level is high to avoid major accidents.

They are very useful safety equipment to maintain peace of mind in the event of possible leaks.

Are Combination Smoke and Carbon Monoxide Detectors Reliable?

Of course, they are reliable. Such dual-sensor smoke alarms combine photoelectric and ionization technology to detect both smoldering and flaming fires or gases and offering you the ideal protection and saves you the hassle of installing different smoke detectors.

Where Do You Mount a Smoke and Carbon Monoxide Detector?

The detectors should preferably be installed on the ceiling, in a fixed position, in a place where their performance is efficient, taking into account that the smoke always tends to rise.

A separation distance of 9 meters can be established between one and the other (in an unobstructed space between the area to be protected and the detector).

The detectors should be placed in the center of the ceiling of the room, as this is where fumes and heat are concentrated.

Respect a minimum distance of 50 cm between the location of the smoke detector on the ceiling and the wall.

When deciding the location of the smoke detector pay attention to the height of the ceiling as this detail can influence the detection: the higher it is, the longer it takes for the smoke to reach the device.

Take as maximum height a ceiling of 3 meters. If it is greater -something that is not frequent in homes-, it shortens the distance between detectors.

You should locate the smoke detector in rooms that require greater surveillance because the risk of fire and gas in them is greater, for example, near the kitchen.

But avoid doing it in an area close to the hob so that it does not trigger without reason with the steam generated when cooking.

For this reason, it is not advisable to install it inside the bathroom either. It is also advisable to locate a detector in the living room or dining room for the electrical appliances and wiring that are concentrated there.

To be safe at home, it is possible to install one in each room. In houses with more than one floor, it is advisable to install at least one on each floor in corridors or distributors, so that the acoustic signal emitted by the smoke detector is audible from all rooms.

Another recommended place to locate a smoke detector is near the exits because in case of fire if the smoke makes vision impossible, you will be able to orient yourself by the sound to exit.

Here are some of the other recommendations for the location of smoke and CO detectors:

  • Avoid installing these appliances too close to radiators, heaters, or vents as the first signs of smoke -can dissipate.
  • Also, do not place them in exits or returns of air conditioning equipment (the currents favor the accumulation of dust, and this causes a malfunction or false alarms).
  • Respect at least a 30 cm distance between the smoke detector and the lamps.
  • The heat they generate attracts dust and these particles can make the detector lens dirty (hence it is important to keep it clean) And don't paint the smoke detector as the paint will prevent it from working properly.
  • If you have multiple smoke detectors in your home, interconnect them so that they all go off if one goes off. You can do it with wired or wireless technology. For this, keep in mind that if they are from the same manufacturer, you ensure their compatibility.

Why Is My Smoke and Carbon Monoxide Alarm Beeping?

If your smoke and carbon monoxide alarm are beeping, that means that the CO has been detected in your area where you have mounted this device. If it is beeping, you should immediately move outside in the fresh air and call the police. And if it is beeping every after a minute, that means the power of the battery is low and it’s time to replace its batteries in your Smoke and CO detector.

Is It Better to Have a Separate Smoke Detector and Carbon Monoxide Detector or Better to Have One of the Newer Combo Units?

If you are not sure is it better to have a separate smoke detector or better to have only one, well we must say that the combined one is the best. Few detectors in the market are more effective to detect CO, flaming fires, smoldering fires, that is why we suggest that you use a combination of such alarms in your home or office for complete protection.

What Are the Best Battery-perated Carbon Monoxide and Smoke Detectors?

X-Sense 10-Year Battery Smoke and Carbon Monoxide Detector


If you are in search of the best battery-operated carbon monoxide and smoke detector, we recommend buying X-Sense (SC01) which is one of the best 2-in-1 smoke and CO detector with LCD.

This Smoke and CO Detectors are effective and very useful devices, designed to detect the presence of smoke or carbon monoxide in a given area and alert passersby through strong auditory and/or visual signals.

These fire-fighting elements are always installed on ceilings, preferably away from windows or ventilation ducts.

Recommendations for its installation include: Having one in the kitchen, one of the most vulnerable areas to this type of accident.

Have smoke detectors on each floor of the home or business to be protected. In the case of using an alarm for business, it is essential to have one in the warehouse area, as it is one of the most common areas to contain flammable material for fires.

The status of the batteries of these sensors should be monitored. Commonly, they do not work in the presence of smoke due to a lack of replacement of batteries.

In the case of having a X-Sense (SC01) alarm, the service includes a lifetime guarantee and free maintenance of these elements. Also, it comes with 10-year battery life.

Key Features:

  • 10-year battery combination alarm.
  • Very easy to install.
  • Digital LCD Display.
  • A single button in the unit to test the detector’s circuit.

Why Stand Out:

  • A feature that encompasses all the elements of the Smoke and CO alarm system.
  • Also, this smoke detector has a wireless connection.
  • These devices don't require cumbersome wiring, chipping through walls, gutters, or external power sources.
  • Each one has rechargeable batteries to be replaced in an automated way by our staff. Worried about when to change them? The smoke sensor and elements of the smart alarm kit have sensors that notify the Alarm Receiving Center (ARC) when they are low.
  • A maintenance visit will automatically be scheduled for you to perform the replacement quickly and at no cost.
