In the fire alarm business, a fire alarm device or system can be a manual fire alarm box, heat detector, waterflow device, flame detector or smoke detector. The term smoke alarm refers to a smoke detector that is not connected to a fire alarm control unit, but operates independently, or with other smoke alarms. Virtual c is mistaken, Commercial smoke detectors operate by the photoelectric principle or the ionization principle. Some photoelectric-type smoke detectors look at the reflection (actually refraction) caused when a light beam bounces off smoke particles. Others have a light source pointed at a photosensitive receiver. The reduction of light received, caused by smoke particles, creates an alarm. Ionization-type smoke detectors utilize a source of radioactivity, like Americium to make a conductive path through part of the detector. Smoke particles interfere with the conductive path, causing an alarm. All are a bit more complicated, but this explains the basics.

HI if you get into a wreck with that much force you NOT going to be getting out of the car on your own and most likely any Electric items are not going to function. What you want it a pressurized system with a impact switch on it that automatically set off the extinguisher in the event of a head on crash. good luck tim
