i have noticed that the fire alarms at my school on the inside do code 3 in sync… the mechanical horns on the outside go AAAA AAAA AAAA…AAAA (repeatedly) they cut out when the strobes on the inside alarms flash… there MUST be a sync module somewhere… so i’m going to experiment with hand- sync protocol i might post a video soon…
Wait, are the horns outside doing code 3?
no they’re not doing code 3… its almost like they are skipping but they do not have strobes… but the electronic horn strobes inside do perfect sync… im thinking the sync module is making the mechanical horns skip…
