You should use these instead of pull stations on your next system test. You could also use something like that MT on hi-lo or use a hi-lo tone on the voice evac system.
Cool video and cool devices! It’s really nice that American collectors are showing European devices. These Eaton call points are less common here but they are very fiddly when you try to place the element in them when it’s on the wall. Where did you get these devices from. You should get a sounder next! Keep up the great work!
