Fire Alarm Wiring

[mstrlucky74]

Can anyone give a quick overview on how this would be wired and with what size wire. Would the speaker strobes get a 2 pair every other device? What about the strobes. Thanks.

Mods,
this should probably be in the low voltage forum?

Style 7 with isolation on the data loop, make sure you bid this correctly!

Not enough info given.

Without making assumptions, which circuit on that drawing would you think is the network circuit?

A 'network' circuit typically interconnects FACPs, which would make sense to use style 7.

None are labeled or drawn as style 7. You need more info to do this. Could be boilerplate carried over.

I'm with nhfire77 on this, insufficient data. While you're asking for clarification, see if you can get the knucklehead engineer or architect to use standard NFPA 170 symbols on his drawing.

Warning total detrailment...

NFPA 170.... I hand drew a 2 smoke detector add to an existing system for a submittal, on an existing drawing. It was a rush to get all permits approved. AHJ approved it, but asked if it was dislexic, because the S's in the smokes were backwards. I get similar responses from other AHJ's. It's too bad
