Yup, I know it's a repair ng, but replacement is the
accepted norm when it comes to these, so this issue boils
down to finding a suitable replacement most of the time.
I had a good unit (photoelectric, made by Honeywell, if I
recall correctly), but was too lazy to troubleshoot it, so I
replaced it with the only unit I could find that worked on
120 VAC. Demonstration by a company that wanted to sell me
half a dozen units (including 2 wind-up heat type) revealed
the ionization unit I have should have been replaced with
another photoelectric type.
These seem impossible to find at Wallyworld or home
improvement stores. Worse yet - I would prefer a dual unit
that works on 120 VAC and have seen recommendations for
units that use both detection systems and include a heat
sensor too. Some internet research seems to indicate the
Cheap units are just that, cheap - and mostly ion only.
There are seemingly no (non-commercial) dual detection
units on the internet
Non-commercial photodetection units seem to be limited to
units without specs, or with poor specs. There seem to be
no references for any non-commercial units to any agencies
which either test or publish verified specifications by
Some commercial units are out there, but there is
invariably no pricing information accompanying them, and all
seem to be microprocessor controlled types (hi $$$$$$ ?).
Has anyone found a good photoelectric type smoke detector or
dual unit available in 120 Volt model suitable or targeted
for the home market? If not, is there a commercial unit
suitable for same?
Is there an agency that tests smoke detectors that publishes
