Since my first time hearing a 34T. They all sound weird for some reason. Is it the type of voltage there on like Full Wave Rectifed?
1st time: 34T by my classroom sounds rough and seems like there was a issue.
2nd time: I walk around while they were replacing pulls. I couldn’t get them or my mom would be mad. All the 34T’s sounded like 9838’s. I’m expecting there going to replace all of them.
Last day of school: The alarm was activated using the drill button. The MT was changed to Steady Horn.
I don’t know if it’s going on battery backup cause the MT sounds fine. Do most electromechanical horns do this on FWR.
Electromechanical horns do sound raspy on FWR, however.
When you compared them to 9838s, are you talking about when a 9838 sounds smooth and nice or when it sounds raspy (if powered by FWR) ?
Another possibility is that the NAC is overloaded, and unable to provide enough power for the signals on the circuit. In that case they should have installed a NAC booster panel such as an FCPS-24S8 in the NAC to keep the power source strong.
It’s sounding like a raspy 9838 however. There’s alot of heat dectectors & smoke detectors. There’s about 21 34T’s and 3 EST Genesis’s with a Integrity which were added in the loudest area’s of the school. There’s a unknown bell on the system too which is defunct.
The panel was installed in August 2013 replacing a EST QuickStart which kept having issues. The only classroom to have a Fire Alarm is my classroom and it’s a Integrity…groan. However they removed the 34T in the cafeteria and the Mirtone pull which was there at some point.
I think it’s time for work to be done to the system. The building was built in 1919 and a new addition was added in 1958. It’s located beside the high school. Google Maps You might find the building interesting too!
