NOTE: 1. All building alarm inputs require an isolated normally-open or
normally-closed contact or switch (rated at 24 Vdc, 20 mA minimum)
connected between the alarm input and common terminal as shown. Building
alarm inputs can be programmed for use with either normally-open or
normally-closed contacts. All control wiring and relay and switch contacts are
customer-supplied.
2. The building alarms can be programmed to display the alarm functional
name.
3. A jumper wire must be connected between pins 1 and 2 on TB1, if the
normally-closed EPO contact is not used.
