RRRAAAIIIIIIIDDD..... Consumer Report writes about this topic in August '80. some quotes from the '83 BUYING GUIDE ISSUE: 2 kinds are generally sold for homes: ionization and photoelectric ionization are quicker - by 20 to 30 seconds - to detect FAST fires such as paper or flammable liquids photoelectric respond earlier - by 20 minutes or more - to slow, smoldering fires, which are more common and cause more deaths. buying the 2 top models of either type was cheaper and more effective than buying one of the 2 combination-models. all models work with a single 9-VOLT battery, which last about 1 year and signal you with a gentle, periodic beep when the battery runs down. Test buttons and testing with cigarette and other smoke is recommended at regular intervals (once a week). installation of 2 detectors (one of each kind) is recommended for each level of your dwelling. smokers should have additional photoelectric devices in bedroom and living-room and other likely places of forgotten cigarettes. The 2 top models in 1980 were: photo-electric: ADT 7535, $25 list-price ionizing: Archer 49454, $17 shopping around for a better price is recommended. ------------------------------------------------------------------------------ werner@ut-ngp { .ARPA or .UUCP }
