Seeing them synced is quite cool. I like that it can support different models of alarms, like ours. Ours are usually always synced, I believe. But I dont know what's doing that, except a sync module of some sort. never seen one. Although i could be wrong - ours may not be synced.
My high school several of these EST booster panels connected to a EST3 since my high school has 7 different wings, library and an auditorium. They're mainly located in maintaince rooms where staff goes and the Genesis does sync with the rest.
Believe it or not, my high school had an EST system with these booster panels, but Wheelock AS notification appliances. It must support some sort of Wheelock sync as the entire school is synchronized.
Sometimes the booster panel is controlled by contorl modules on addersable systems and some brands like simplex make addersable nac boosters such as the 4009 idnet nac booster which my school has in some of the portables
I had a fire drill at school the tone the Genesis speaker strobes were playing was not what I expected, the tone does a slower code 3 and it’s slightly lower pitch, some of them were somehow out of sync, but most of them were in sync. The reason why the tone is lower pitch and slower, is because the panel in my school is an EST2 panel
That actually isn't true. The 900HZ code 3 tone WAS a BOSTON specific, Particularly used on EST systems. I've inspected plenty of systems in mass that just played a whoop tone or a code 3 520HZ. Nowadays, boston voice evac systems require a temporal 3 (1khz or 520) or steady tone, and no message unless the engineer requests it. In highrises it needs to follow a specific script. Many engineers from boston will do work outside of boston in MA and use the same specifications. My high school plays a slow whoop tone, and it is in mass about an hour from boston. I inspected a school with an EST3 that was installed in 2017 and it played a 1khz steady tone and a voice message with the specific script, (because it was installed by a company in Boston and they used the same spec.) it followed the boston spec but wasn't required by state law.@@MatthewKelley1206
Hey, I'm an electrical contractor retro-fitting a class A fire alarm into a small apartment building (20 Units Total). It currently only has a Class B system for the hallways and the FAP has only two NAC's. We're adding a Class A system for horns in the suites (requiring 4 NAC's, one for each floor) and we were told we needed a whole new panel that could provide the 6 NAC's required. Would this Booster Pack (NAC Extender) work for what we need? In your video you added one device to each NAC on your booster, but could it support up to 10 devices on each NAC? Thanks for any help!
Hey, I just waned to ask as well, at 1:23 you're showing the additional 4 NAC's you're adding (which is exactly what I need) and the description on the diagram has a 'Typical Class B' and 'Typical Class A', is that just for reference or can you only use a 'Class B' circuit in that first position and only 'Class A' in the last? Hope that makes sense.
Um I am kinda confused with the tone as of 1200hz as in 900hz but some green hill/emerald hill community college career center services building in state of Massachusetts should use code 3 specific tone then voice message trilingual or just tone only thought but I did tried my best though. But there is genesis led strobe series but thy still have genesis xenon strobes ones though which it is synchronized though but Perrysburg county is getting Edwards system then I think. But the Massachusetts code 3 tone should be compatible for the Edwards system est4 panel system of voice evac. But jeez the mechanical horn started me at the almost to the end of the video. By the way for one more thing Edwards kidde brand for addressable alarms does need to be at 900hz for Massachusetts alarms.
