Ansul fire protection

[Rlmwireman]

In a commercial facility that has 2 areas 120 feet
Apart with fire protection do they need to integrated. I.e. one activated does it need to
shut down supply fan, receptacles etc. in other
One. Or can they act entirely separately?

Sometimes multiple systems are tied together, sometimes they operate independently.

I suggest calling your fire marshal or building department to ask what determines it.

The usual rules are, when there's a system trip:
The exhaust fan must come on or stay on.
The make-up air fan must turn off or stay off.
All electricity under the hood must lose power.
Electric gas valve: exhaust on, gas reset button.
Mech. gas valve: T-stat w/10-minute exhaust.
Horn/strobe or building alarm connection.

If the systems share common duct work, the answer will be "yes." If they don't, the answer will be "no" as 120 feet is enough to prevent one system presenting a threat to another. If you can grab a copy of NFPA 17A that might help you out. Or bore you to tears.
