Nothing is more important to your family’s safety than your home’s smoke detectors and fire alarms. These devices alert you and your family where there is dangerous smoke or fire, giving you enough time to safely evacuate. However, you need to routinely check your smoke detectors to make sure they are working.
Let your family know that you are testing the alarm. Smoke detectors have a very high-pitched sound that can frighten pets and small children. Let everyone know your plan and that it’s a test.
Have someone stand at the farthermost point away from the alarm. This is key to make sure the alarm can be heard everywhere in your home. You may want to install more detectors in places where the alarm sound is muffled, weak or low.
Now you will want to press and hold the smoke detector’s test button. After a few seconds, you should hear an ear-piercing, loud siren from the detector when you press the button.
If you don’t hear anything, you must replace your batteries. If it’s been more than six months since you replaced your batteries (which could be the case with hardwired alarms) change your batteries immediately, no matter what the test result was.
You will want to test your new batteries one last time to make sure it’s working properly. Make sure you check your smoke detector to make ensure there is no dust or anything blocking the grates. This can prevent the alarm from working even if your batteries are new.
Even with regular maintenance and if your device seems like it’s working, you will want to replace the detector after 10 years or even earlier, depending on the manufacturer’s instructions.
Owon smoke detector SD 324 adopts the principle of photoelectric smoke sensing design, by monitoring the concentration of smoke to achieve fire prevention, built-in smoke sensor and photoelectric smoke device.The smoke moves upward, and as it rises to the bottom of the ceiling and into the interior of the alarm, the smoke particles scatter some of their light onto the sensors. The thicker the smoke, the more light they scatter onto the sensors.When the light beam scattering on the sensor reaches a certain degree, the buzzer will sound an alarm. At the same time, the sensor converts the light signal into an electrical signal and sends it to the automatic fire alarm system, indicating that there is a fire here.
It is a highly cost-effective intelligent product, using imported microprocessor, low power consumption, no need to adjust, stable work, two-way sensor, 360° smoke sensing, fast sensing no false positives.It plays an important role in early detection and notification of fire, prevention or mitigation of fire hazards, and protection of personal and property safety.
Smoke alarm 24 hours real-time monitoring, immediate trigger, remote alarm, safe and reliable, is an indispensable part of the fire system.It is not only used in smart home system, but also in monitoring system, smart hospital, smart hotel, smart building, smart breeding and other occasions. It is a good helper for fire accident prevention.
