Also, if you have your fire extinguisher system checked professionally on a regular (annual) basis, they would instruct you in the use of that switch!!
‘On’ if it fails to go off automatically.
I suspect it overrides the automatic fire shutdown, allowing you to restart the engine(s). Automatic shutdowns typically go hand in hand with an automatic fire extinguishing system in equipment space. When the fire system activates and discharges the suppressant, then engines and fans need to be shut down at the same time, otherwise they draw all the suppressant out of the equipment space rendering it useless.
But then you need to get running again, and that's where an override switch comes into play. It overrides the automatic shutdown, and you can restart.
When all else fails... Read the instructions.... Said thoughtfully tongue in cheek...
As an English major, of course that means...um...yeah, no idea. Ha!
If you have the info and you haven’t read it, sounds like a Darwin event to me...
Years ago, there was a can parked in my neighborhood in Boulder with a hand-lettered sign:
"Not for sale. Also a piano"
Sorry, I had a hard time on the for sale and piano part as I was still hung up on the can.
I , but rather some homemade addition to ground out the switching-off system.
Constipated?
