Looking for insight on my issue. Car does not respond to hall calls or car calls. 8 landing tac 20 simplex, 4th landing to top floor hall fixtures / arrival lantern blinks continuesly. Daisy chain hall call boards, all boards has green led lite. Reseed each connector. On IMS get 1085 faults, and CHK SHUTD. Can move car inspection. Vertify all normally closed contact inputs good. Notice HSF1 (hall fire on) is off which is normal, but HSF2 ( hall fire off) should be on, did jump the switch but no success. In IMS can force fire phase 1 on, car return to fire landing and door stays open. Assuming the software is good.
How can I proof my hall node(L24 board) is bad and which one?
If the hall network fail should be able to have car calls? Right?
