Alarm trip loop that is "bi-polar" meaning both NO and NC type trip switches (the two right-most) operate one lamp alarm.  The circuit starts tripped (the left-most switch resets the trip), ideal for testing on first power up and/or if power fails, and is restored while you're not around, a notation carries it would start up in alarm tripped for indicator of that - nforystek
