Old style AF timer

Wed Sep 14, 2022 11:40 pm

I’m wondering if anyone has any documents on the older AF timer (the ones with no cancel button)

I’m working on a siren in mapleton Utah and it had one of these timers. If anyone has any wiring diagrams please send me a picture. Thanks.

Is this one of the older 'horizontal aspect ratio' timers? There's some information here, but sometimes the photos don't load:

What do you need to know?

How are they wired and can I wire a cancel button?
