OK, something is up around here. I can't remember who it was who started a thread about the ghosts in their house. I put in my 2c worth of skepticsim, but now I believe there's something to it. My house has the little impish spirits running around, but I'm hoping I got rid of them. They were setting off my fire alarms, and there was nothing I could do to stop the din. I replaced the batteries. I took out the batteries. I reconnected the wires. I disconnected the wires. Finally, I got so fed up with the d*** things, that I took them all down and threw them in the kitchen trash. At least one of them kept beeping once every 10 seconds or so: No battery, not hooked up to any electricity. I had to take the trash out so I wouldn't have to hear it anymore. Now I have holes in my ceiling and no fire alarms. But it doesn't matter; they were useless, anyway. There was one in each bedroom and one in the hall. Both doors to the outside and the most likely places where a fire might start are all at the other end of the house. So if we did have a fire, the alarms would go off (assuming they worked when they are supposed to) just in time to tell us that we're about to die. :evil: Anybody know a good exorcist, just in case the fire alarms start going off even though they are all gone?:shock: Snuff
You may have had photoelectric detectors which often have a back up battery. The back-up battery may have been giving the warnig of low voltage. http://chemistry.about.com/cs/howthingswork/a/aa071401a.htm Both ionization and photoelectric detectors are effective smoke sensors. Both types of smoke detectors must pass the same test to be certified as UL smoke detectors. Ionization detectors respond more quickly to flaming fires with smaller combustion particles; photoelectric detectors respond more quickly to smoldering fires. In either type of detector, steam or high humidity can lead to condensation on the circuit board and sensor, causing the alarm to sound. Ionization detectors are less expensive than photoelectric detectors, but some users purposely disable them because they are more likely to sound an alarm from normal cooking due to their sensitivity to minute smoke particles. However, ionization detectors have a degree of built-in security not inherent to photoelectric detectors. When the battery starts to fail in an ionization detector, the ion current falls and the alarm sounds, warning that it is time to change the battery before the detector becomes ineffective. Back-up batteries may be used for photoelectric detectors.
