But, hey, you should be changing it every six months anyway. The Garvan SS-166 Smoke Alarm is an photoelectric 9V DC smoke alarm. So your battery life span may not be as good. The photoelectric ones probably are more power intensive. It’s similar to the Americium-241 smoke detectors in some ways. And again, you can get false positives because organic compounds often absorb infrared light really well. If it is tuned correctly, you can interpret that change in current as the presence of smoke.

But when smoke goes in, it will make the light scatter a different way, or block the light in a certain way, and that will change the amount of current that’s flowing. The light can be shining and you get current.

Engineers figured out how to tune a light source in a way that is sensitive to smoke. When light hits something, it generates electric current – it’s very much like a mini solar cell. It’s what Albert Einstein got the Nobel Prize for. Is there a better smoke detector?Ī newer kind of smoke detector is based on the photoelectric effect. Smoke particles block the ions, stopping or reducing the flow of current, which sets off the alarm. So, that lowered current is what your sensor interprets as, hey, there’s smoke here. If smoke is coming into the area where this breaking apart is happening, it will block the charged particles from moving, reducing the current.

Read this manual fully before attempting insta and retain. This owners manual contains important information on the correct installation and of your gas leakage alarm. Alpha particles from the radiation source strike air molecules, which causes them to eject ions, creating a current. Garvan 12V DC OPERATED GAS ALARM (HOT WIRE TYPE) WITH AUXILIARY RELAY (Optical) MODEL : MTG-3000H (GENERAL MODEL : MTG-3000HR RELAY) IMPORTANT PLEASE READ CAREFULLY AND SAVE. current technical manual/data sheets and the requirements of the Authority having. This movement of charged particles is what we call electrical current. silencing/hush facility, interconnectable, ionisation smoke alarm. And those two oppositely charged ones will be attracted to the negative and positive battery terminals in the smoke detector’s battery. BS 5446 Part 1: 2000 LICENSE NO: KM 53166 lii1 CLASS II l:J APPARATUS. When that happens, some broken pieces will be positively charged, and others will be negatively charged. IONIZATION SMOKE ALARM MODEL: SS-12388 (With 9V Battery. These little bullets come out of the source and hit air molecules to break them apart.

It emits alpha particles, which you can think of as little bullets. Inside your smoke detector, there’s a small Americium-241 radiation source that’s a byproduct of nuclear fuel. The Camille and Henry Dreyfus Foundation, CC BY-NC-ND
