Home Forums General Discussion Technical Questions SCINDLER/HAUGHTON CALL CANCEL ISSUE

Is the FX relay at that floor working? Some jobs used FA relays but the FX relay contact has to make to pick a CC relay which in turn fires TR and cancels the call. The call circuit is just a self holding contact through a 47 ohm resistor on the timer display board. To cancel the call you first need the associated FX relay to make up.
