This is the first time I worked on a Simplex 4004 that is used for general alarm. I downloaded a .pdf installation manual for this panel but it doesn’t explain what terminals 1, 2, 7, 8, 9, 10, and 11 on the main board are for and how they are used.
I have a AP&C model relay card with 24 VAC attached to the “N/C” and “C” dry contacts that cuts power to the door holders when panel goes into Alarm mode.
Also, the panel door LED alarm zone display is not working.
The ribbon cable going to the alarm zone indicator card has the black wire and adjoining wire stripped for connecting but they are not connected to the panel terminals. I suspect that the indicator card gets its’ power from the terminal connections and the relay card is powered from the terminal connections when the fire panel goes into alarm.
Any help would be greatly appreciated.
