What happens if your smoke detectors goes off but there's no smoke?
This may because specs of dust can cause activation of the detector as it has the same effect as smoke. Spiders also can crawl into the sensors which does the same thing- same way with deodrant, paintfumes etc. It also may be because the smoke detector is just faulty.
Will marijuana set off a smoke alarm?
Not unless it is smoked in the vicinity of a smoke detector.
How does a smoke alarm work?
press onThere are two kinds of smoke detectors. 1. When a fire burns, it releases smoke. The smoke detector senses the smoke. 2. A fire is very hot. The detector feels the heat. A smoke detector will then either set off an alarm, or it will turn on the sprinklers.
Do smoke detectors detect ciggarette smoke?
smoke...The reason that sometimes we cannot see smoke is because of the very tiny "particulates" that make up the smoke. A good smoke detector mwill sense smoke long before it can be seen. It is particles in air that are very very small that a smoke detector detects.
Will incense set off a smoke alarm?
Any type of smoke, steam or particles denser than air will set off a smoke alarm. This means that smoke emitted from the incense will set off a smoke alarm when in range of the detector.
Would a hot shower make a smoke detector go off?
no, hot showers may produce Steam, not smoke
Do sulfur candles emit enough heat to set off a home smoke detector or fire alarm?
Home smoke detectors generally respond to smoke, or products of combustion more readily than heat. Unless the candle was placed directly under the detector, it is unlikely to produce enough heat to trip a heat element. It is very possible though, that it could give off enough combustion products to set off the smoke detector.
Where the house wiring is black white and green but the smoke detector is wired red white and black How do you connect them?
black should be your hot white your neautral and the red should be the interconnect to another smoke alarm so that if one goes off in the upstairs the down stairs one will go off also because they are joined by the red wire(interconnected) check for another smoke detector(the red/black/white)should be fed from it to were you are talking about
How can you keep the smoke detector from beeping temporarily?
Push the button, or take the battery's out (not recommended) In many modern smoke alarms it is impossible to remove the battery, but there may be an on/off switch that can be actuated with a tool. If the alarm is beeping because the battery is dead, replace the battery or the entire alarm unit, which should be done every ten years anyway. Removing a battery in any smoke detector could be criminal "tampering", if anyone gets hurt because of it.
What are important about heat detector?
They detect heat instead of smoke. They are widely used in boiler houses, kitchens where a lot of steam and smoke is created. If a smoke detector was installed in this application, then there would be a lot of false alarms. So instead, they detect the heat intensity of a fire which will set off the fire alarm. They are also less likey to be set off by accident. Spiders, dust, deodrant etc sets off smoke detectors quite frequently. this does not happen in heat detectors.
Why do you have to test an ionizing smoke detector?
You have to test it frequently, the reason is that smoke may be visible or may be not and you want to see all particles that emanate from any kind of smoke, specially during night time when you are asleep. Most of dust/ash particles may not be visible and via ionizing detector they will be!!!! Alarm will go off making alert sound and you will be safe. So, sumirizing, you need to test ionizing smoke detector to see if sensor is in ok condition.
What use is alpha radiation?
It is used in smoke detectors as it cannot travel far in air. Alpha radiation is emitted and as long as the detector in the device is receiving the alpha radiation, then no smoke is present. When smoke particles are present, they interrupt the radiation, and so the detector doesn't pick up the radiation, causing the alarm to go off.
