OP here, I ended up purchasing one USI MI106S, which advertises the following:
- Combines the benefits of both Photoelectric & Ionization technology in one alarm
- Smart Alarm Technology virtually eliminates nuisance alarms
- Automatic temperature and humidity compensation continuously adjusts to variations in environmental conditions, reducing nuisance alarms
Which sounds like what I’m looking for. I’ll try some informal tests on it before I buy more.
Why eat bugs when you could eat lentils?
