Hi All,
I am trying to build an internal alarm system for work. Nothing too fancy, but I'm having trouble narrowing down the parts to get what I want.
In the office we have a small lab (call it "Lab A"), then a larger lab ("Lab B"). The two labs are (acoustically) sealed off from each other and from the rest of the office. In "Lab A", if an emergency condition is reported, we receive an alert, which sounds like a telephone ringing. The ringtone is fairly loud, but a person must be physically located in Lab A to know about the condition, and respond to it. If someone is not physically in Lab A, then we lose our ability to immediately respond to the emergency.
What I would like to do is wire up a system so a sensor in "Lab A" can detect when the alerting ring comes across the speakers. When it does, I would like that sensor to trip, activating the alarm so people in Lab B can know that there is an alert in Lab A. Ideally, I would prefer a strobe light to flash instead of a horn or alarm. A person in Lab B can see the flashing light, and go to Lab A to respond as needed.
Any ideas? Thanks!
