We have an old buzzer+lighing system connected via analog port for hotline numbers in a noisy environment. With ringing voltage this system goes off. This is old system and it is acting up. Every now and then it stops working and they have to power cycle to resolve it. Unfortunately there is not much make and model details available.
Following information is found on the device:
UTA-1
INPUT: 40-130V 20-30Hz/48VDC

Does anybody know a good buzzer+lighting system to work on analog (fxs) port?
Thank in advance!
