NOTE 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.
NOTE The building alarms can be programmed to display the alarm functional name.
NOTE A jumper wire must be connected between pins 1 and 2 on TB1, if the normally-closed REPO contact is not used.
