Fire Alarm NAC test

A Simplex/Grinnell tech was testing our FA system, and I recorded the NAC test. The reason you see walls/floor is privacy (simmilar to SimplexTech). Of course, I did get the strobes when they went off. Also sorry about the shaking afterwards, I get a little jittery after things like this. The buzz you hear is the Stopper pull station cover.

I don't understand how that can be a thorough test since the alarms are only sounding for about a minute that is a three story building no way anyone could check them all that fast.

@Gb755c I always thought the same thing. But maybe our local AHJ (Authority Having Jurisdiction) doesn't require a full NAC walkthrough… who knows.

How often are NAC tests done there?

@Gb755c Once a year (official inspection)

@phillies4100 The original Zans 400 motherboard was either set to continuous or the panel was set to interrrupted meaning the panel isn't doing the coding and it's whatever the jumpers on the wheelocks are set to. Most likely since it's doing Code 3 the SK 5208 is probably set to code 3 and the jumpers on the horns were either set to accept the panel's code or were set that way already

5208

why is this code 3 i thought it was continuous during the real fire?

...and that's why the strobes were flashing temporally instead of steadily.
