Hey guys, I have a couple questions about fire alarm wiring in regards to the relays that control elevator recalls.
I know how recalls work and why they function I was just curious of how the relays for them work electrically. Do the primary, secondary, and fire hat relays work on the Normally Open contacts??? (which is what Im guessing?) or the Normally Closed? is it the same for shunt??
Im guessing it would be the Normally Open so when the relays fire in alarm, it makes a connection to fire a circuit, circuit board or whatever in the elevator control box to initiate the recalls and turn on the fire hat light. Am I correct with this take??
Thanks in advance for the help in understanding!
