NOTE: 1. 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.
2. Regardless of assignment, alarms display as Building Alarm 1 and Building
Alarm 2 on the Control Panel Display Screen. Use twisted-pair wires for each
alarm input and common.
3. A jumper wire must be connected between pins 8 and 9 on TB1, if the
normally-closed EPO contact is not used.
