Testing Home Smoke Alarms with Smoke Centurion 

Its the Cessna aviation company Or a part of it i believe

Photoelectric detectors contain a very dark (to keep ambient light out) smoke sensing chamber that involves a light beam and a light sensor slightly offcenter from the beam. When smoke particles come in, they reflect the beam into the light sensor. The way the test button tests these is by shining a beam of light directly into the sensor. Ionization detectors contain a chamber with a small radioactive material (we're talking a field that can slightly harm an ant, we're not talking Chernobyl) and two plates that create an electric field using the radiation. When smoke enters, it disrupts the field triggering an alarm. The test button will remotely interrupt these fields. Most detectors however only test the sounder and (if applicable) the LED, and not the chamber, which is why Smoke Centurion and Solo A4 were invented.

Who knows

They are over 10 years old but he can replace them if he wants or not but he moved away so he can’t do anything about it.

What type (BRAND) is the alarm .

The first 3 detectors are not Kidde's, there FireX FADC's. They just look similar to the Kidde FireX I4618AC's. The second to last one was a Kidde I9010, and the last one was a First Alert dual sensor.

Probably, just the right wires and voltage. Only if you have a wired system not wireless

if you have a hard wired smoke alarm you can connect the wire that sends a signal to other smoke alarms to a relay that could connect to a fire alarm control panel or a horn

It’s in a wall really high up

It’s actually on a wall very high up

Can can? And what does a smoke detector have to do with a beekeeper?

Great video!!!!!!❤❤❤❤❤
