Definitely going with photoelectric for my home!

Wait, are video detectors even a thing for fires?

I thought ionization was better for that?

Totally agree, they detect smoke better!

I'm a bit confused; I thought rate of rise detectors were for heat detection, not smoke. Does that mean they wouldn't be suitable here?

I feel like we had a practice question about this, and it mentioned that photoelectric ones are good for detecting smoke from smoldering fires.

I remember studying that ionization detectors are more sensitive to fast-flaming fires, so I guess that rules them out for this question.

I think the photoelectric detector is better for smoldering fires, but I'm not completely sure.

Photoelectric seems like the obvious choice here. Ionization detectors can miss the slow-building smoke from smoldering fires.

Video smoke detectors? I've never heard of those. I'm going to have to go with photoelectric on this one.

Photoelectric for sure. Ionization detectors are better for fast-burning fires, but photoelectric are more sensitive to the slow-building smoke from smoldering fires.

Hmm, I'm not sure about this one. I'll have to think it through carefully. Maybe the ionization detector would be better for low-energy fires?

I think the photoelectric smoke detector would be best for detecting smoldering fires, since it uses a light beam to detect smoke particles.

Video smoke detectors? I didn't know we were playing 'Where's Waldo: Smoke Edition'. Photoelectric is the real MVP here.

Ionization detectors? More like 'ion-izing' my brain with these silly choices. Photoelectric is the winner, hands down.

Rate of rise? That's for the adrenaline junkies. I'll stick with the good old photoelectric detector, thank you very much.

Yeah, they are more reliable for those types of fires compared to ionization detectors.
