How would the fire department know there was a gas leak in the building unless they were on the scene?

This Battalion Chief Bubba, is this the Manager? OK, we've automatically detected a gas leak from interior gas alarm sensors. You better smash all the windows before the place blows. We're responding to the scene code 3 now.

Well if the manager on shift had received no training on the alarms in the building that might work.

But who would install a silent alarm on a gas detector? The point of such alarms is to alert the occupants of mortal danger. I have smoke alarms with CO detectors in my house because I gas heat. They have audible alarms.

But like I said this is a display of total lack of critical thinking.
