garage door relay
garage door relay
(OP)
I need help. I work at a fire station and I need a relay, or some device that will keep our station safe. Here is what I need it to do. When the tones drop at our station, I need the garage doors to open, wait 3 minutes, and then close behind us. I also need to be able to manually open the garage door without it shutting automatically. If the garage door is open and the tones drop, I need the doors to shut after 3 minutes. Does anyone have any suggestions?





RE: garage door relay
If you work for some kind of city or county agency, maybe someone who does your streetlight controls can help you?
Doesn't seem like a difficult project, just need to gather the details about what you already have in place, and figure out the best way to automate it.
Hope that helps,
