NOTE All building alarm inputs or remote features require an isolated normally-open contact or switch (rated at
24 Vdc, 20 mA minimum) connected between the alarm input and common terminal as shown. All control wiring and
relay and switch contacts are customer-provided.
NOTE Regardless of how you assign the building alarms, the default is to display the alarms as Building Alarm 1,
Building Alarm 2, and so on, on the monitor panel. Use twisted-pair wires for each alarm input and common.
