Interesting how this video sat for three years plateauing at 1.4k views, then gets mentioned by Technology Connections on 9 July and suddenly everyone is interested in photoelectric detectors due to this 'alarming' revelation
The Australian building codes board is wasted space. Says a lot about them. Disgraceful. There needs to be ONE of EACH. One ionisation and one photoelectric alarm. and they need to BOTH work. Photoelectric in the kitchen, Ionisation installed some distance from the kitchen. Working ionisation smoke alarms should be in bedrooms accompanied with a working photoelectric smoke alarm. One of each. Fully lit fast burning fires tend to emit finer particles; Ionisation works better with fine hard to see particles from a fully involved fast burning fire. Photoelectric detectors are very good at detecting large visible smoke particles from say a faulty electrical appliance/lit cigarette on the couch that may ignite the couch. Something that may not be burning but poses an extremely serious danger to life. I.E. that appliance becomes fully lit with fire. Ionisation for Fast burning fires Photoelectric for Pre-fire/slow burning fires. Cover ALL bases. ONE of EACH. ESPECIALLY the BEDROOMS.

Technology Connections also brought me here! And now my family’s home has photoelectric instead of ionisation for every alarm in the house.
Thanks Alec!
I have added photo electric alarms to my house so I have both. Thañk you 60minutes.

Of course not rocket science I have both.
Dual sensor alarms exist 🙂
