As always, CoolP wins the prize of master of Trivia!
AUTO PACK TRIP
With the system armed before takeoff, thrust loss on any engine during takeoff & climb with flaps out of the up position will: TRIP BOTH pack fans instantaneously and trip off both packs and turn on the ENG FAIL light on the pilots glare-shield. This allows the remaining engines to develop a bit more thrust for the remainder of the takeoff and climb portion of the flight.
CS shows this light on the 727-100, but I only remember this system on the 727-200 model. It could be possible that it could have been added to later -100's. The 727 I flew did not have this on the -100.
