Does this have both photoelectric and ionization sensors?

it has photoelectric and a heat detection sensor. It does not mention ionization sensor.

The manual states "It's eight sensors work together to understand what's happening in your home and it's photoelectric sensor detects slow, smoldering fires". Did not find any other technical information relative to your question.

According to the instructions, this device is ionization. I believe a photo would cost more as well.

Yes it has a photocell. Has 3 manually adjustable dials underneath for sensitivity (30%-100%), photocell (on 24/7 - night only), and time (5 seconds - 12 minutes)

No. An No-one has wirelessly interconnected detectors that use both technologies individually in separate detectors. First Alert OneLink uses photo-electric technology, and has no ionization detectors. The best you can do with wireless technology at this time is to put one each of the Kidde and First Alert detectors in each room.

NO! Basically, if the question needs asking, then the answer is that it does not. It detects Carbon Monoxide and Methane (a component of natural gas).

Yes it is photo electric and communicates wireless to paired units. Another model has voice announcement for the location of the alarm.

Yes, I bought two kits installed them both and use one remote to operate both. The IR sensor is small and near the control unit so make sure they are placed in an area where the remote can see both.

It does not have an ionizer. It has power button, speed, breeze and reciprocation.

It has a HEPA and pre-filter but does not say anything about ionization in the manual.

Steve, it does have both but I have to say I have not been happy with this product. It seems to stop running for no apparent reason quite often.

No. There is no on/off switch on the sensor itself. If you want that function, you should wire it up through a wall switch or circuit breaker.

No, I am reasonably certain it does not have an ionizer, just the carbon and hepa filters.

These are photoelectric smoke detectors. They are less sensitive than the older smoke detectors you might be used to. This is done on purpose so it doesn't go off every time you burn something on the stove or create a lot of dust or steam. From wikipedia: According to the National Fire Protection Association (NFPA), "photoelectric smoke detection is generally more responsive to fires that begin with a long period of smoldering (called smoldering fires)." Also, studies by Texas A&M and the NFPA cited by the City of Palo Alto California state, "Photoelectric alarms react slower to rapidly growing fires than ionization alarms, but laboratory and field tests have shown that photoelectric smoke alarms provide adequate warning for all types of fires and have been shown to be far less likely to be deactivated by occupants." Although optical alarms are highly effective at detecting smouldering fires and do provide adequate protection from flaming fires, some fire safety experts and the National Fire Protection Association recommend installing what are called combination alarms, which are alarms that either detect both heat and smoke, or use both the ionization and photoelectric/optical processes. Also some combination alarms may include a carbon monoxide detection capability.

Probably. BRK owns the First Alert name. Some details may be different such as the wiring harness. These have worked perfectly since I've installed them. They replace some obsolete ionization only detectors.

This model does have a light sensor and turns on a dusk and off at dawn. I have been using it for years with no problems.

No this unit works all the time with ionization on. I just use mine when I need to get rid of odors. I don't run it all the time.

I have to assume it did/does. I bought it as an additional sensor. It operated very erratic and often with nothing to set it off. Once sounded, I'd have to shut the unit off to reset it.
