Trouble Output Wiring
The trouble output is wired to a Fire Alarm Trouble Only monitor zone. This is done to monitor
the DTC-300A. The E.O.L resistor required for this zone is to be placed on the terminals
marked E.O.L. below the Trouble Output. The value of the E.O.L. resistor depends on the
FACP used. For the Mircom FACP, use 3K9 ohms. The Trouble Output terminals are dry
contacts. Use JW4 to select either normally closed (pins 1 and 2) or normally open (pins 2 and
3).
