Hello all,

Has anyone experienced a car call button acknowledgment light that didn't cancel on these units?
It's only 1st floor and I changed the (K2EB) I/O board (Part #ABA26800AHE1) that it plugs into with same result. Button works fine. Able to move problem to any call button.

Also on the same car the Fan & Light Protection relay (FLPR) picks up instantly and won't drop out to allow car lights to turn on. Changed CIRS board (Part #GDA25005B1) and no change.

Any help at all is good help. Thanks for reading this.
