DTC-300A-2 MAIN BOARD INPUT ZONE WIRING
There are terminals for six input zones. Zones 1 to 6 are configurable. The default zone settings are as follows:
Input zones 1 through 6 can be connected to the form C relay contact outputs of an associated Fire Alarm panel.
These relay outputs show the status of the Fire Alarm panel as Alarm, Supervisory, Waterflow Alarm, Common
Trouble, AC Power Fail Trouble and Battery Trouble. Each input zone is supervised by an 820 ohms End of Line
Resistor or equivalent MP-820R/W which is a resistor on a white or red plate.
