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.
