Os detectores de fumaça detectam monóxido de carbono monóxido de carbono? Or do you want a detector containing both smoke sensor and CO sensor? This blog will look into these questions and recommend a combination smoke & CO smart detector. Também, we well mention some tips about device placement.
Wireless Smoke Alarms
The wireless smart sensor de fumaças contains a built-in smoke sensor. After smoke enters the sensor, it disrupts the ionization balance inside the sensor. This disruption causes changes in current and voltage. Until this change reaches the preset threshold, the detectors will alert by sounds and lights. E, it can wirelessly transmit the alert information to the user’s phone anytime anywhere. It’s very convenient.
Além disso, it has other benefits for users. Compared with traditional wired smoke alarms, wireless smoke smart alarms are easy to install without considering the external power supply. When the battery is low, the alarm will sound a reminder or flash an indicator to remind the user. De um modo geral, it can be installed in the family’s living room, bedroom, kitchen to ensure the safety of family members.
Carbon Monoxide Detectors
The working principle of wireless carbon monoxide smart alarm is mainly based on electrochemical reaction. Its built-in reference electrode and measuring electrode can be used to detect carbon monoxide. When the detector is exposed to CO, the measuring electrode quickly converts the presence of carbon monoxide into an electrical signal, which is proportional to the concentration of carbon monoxide. The electrical signal will, then, go to the alarm’s microprocessor. If the measured value exceeds the preset safe value, the microprocessor will issue an alerts in the form of sound, light signal, and even a digital message to the user’s phone. Além disso, some of the high-tech CO detectors can be connected to smart exhaust fans and air purifiers via the IoT network. Por exemplo, if the concentration of carbon monoxide exceeds the standard, it will not only issue an warning but also trigger the smart exhaust fan for ventilation. Desta maneira, the high concentration of carbon monoxide indoors will be discharged in time, so the health of the family will be protected in time.
What Is the Difference Between Smokes Detectors and Carbon Monoxide Detectors?
| Smokes Detectors | Carbon Monoxide Detectors | |
| Main Function | Detect smoke | Detect carbon monoxide concentration to prevent carbon monoxide poisoning |
| Sensor Principle | Lonization principle, Photoelectric effect principle, Pyroelectric principle, Sonic principle | Electrochemical reaction principle to convert CO data into electrical signal by electrode reaction |
| Application | Lar,office, school, hospital mine | Kitchen, parking lot, chemical industry |
| Placement | On roofs or near smoke sources | Generally installed in areas where there is frequent activity, such as the living room or kitchen. |
| Manutenção | Regularly clean the dirt on the alarm, Check the battery status | Replace the filter inside the alarm regularly Replace the battery and filter in time |
| Sensibility | Fumaça (but it may be sensitive to CO due to false alerts if there is dust and water) | CO (the false alerts rate is relatively low) |
| Alerts | Sound, light signals, digital transmission | Sound, light signals, digital transmission |
Do Smoke Detectors Detect Carbon Monoxide?
If it is just a smoke detector, it cannot directly detect carbon monoxide. Because carbon monoxide is a colorless, inodoro, non-irritating toxic gas. Compared to smoke, it significantly differs in physical and chemical properties. The main function of a single smoke alarm is to detect smoke particles in the air. Obviously, this principle does not work for detecting carbon monoxide molecules. For cases where carbon monoxide detection is required, we recommend a professional carbon monoxide alarm. The carbon monoxide alarm can accurately detect the concentration of carbon monoxide in the air through the principle of electrochemical reaction. Alternatively, we can use integrated 2 in 1 Fumaça &CO detector.
Benefits: Why Not Combine Smoke Detector and CO Alarms
Although the unit price of a smoke alarms or a carbon monoxide alarms may be relatively low, 2 in 1 smoke CO alarms have a higher cost performance. Because it can detect two kinds of substances at a pretty cost. Além disso, users can enjoy two detection services in one installation. This greatly reduces the complexity and labor of installation and maintenance.
What Is Combination Smoke Detector and CO Alarms?
Combination smoke detector and CO alarms is an smart security device that integrates the detection functions of smoke detection and carbon monoxide. Such alarms are typically designed for household and commercial buildings where the risk of fire and CO leakage should be monitored simultaneously. Its alert module usually contains an audible and visual alarm to warn of the risk of fire or CO poisoning. Some advanced products also have remote notification functions. When an anomaly is detected, an alert message can be sent to the user’s phone through the mobile APP.
Great Importance of the Location of Combination Smoke & CO Detector
Early Warning to Reduce Losses
Fire and CO poisoning are serious safety hazards. Once they occur, they often cause huge property losses and even casualties. The combined alarm provides an immediate warning in the early stages of a fire or CO leakage accidence, so this buys valuable time for evacuation and emergency measures.
Double Protection to Improve Safety
In tradition, smoke alarms can only detect fires, while carbon monoxide alarms focus on the detection of carbon monoxide leaks. The combined detector integrates the two functions in one, improving the overall safety.
Placement of Combination Smoke & CO Alarms
Recommended Installation Location
We can install a combined alarm in the bedroom to immediately alert the sleeping family in the case of a fire and excessive CO concentration indoors. Também, we can install an alarm at the entrance to the kitchen or at a location that is far from the cooking area but covers the entire kitchen. After installation, we need to ensure that the alarm is not blocked by furniture and curtains, so that it can smoothly detect smoke and carbon monoxide.
Recommended Installation Height
From the perspective of physical principle, smoke usually rises, so we can place smoke detectors with single detection function at a high position in order to detect rising smoke in time.
Em contraste, carbon monoxide is slightly denser than air. But given its excellent diffusivity, we can not overemphasize the sinking properties of CO in the air. Em geral, we can install combination smoke & CO alarms in a height range of about 1.5 para 1.8 meters from the ground. This height both ensures smoke detection and CO leaks detection.
