How do I wire and program the FX-10 onboard relays for connection to a building management system?

The FX-10 onboard relays are located at TB3 and provide common signals for Alarm, Supervisory, and Trouble events. These relays are not field-configurable and do not require programming as they are pre-programmed to change state based on common system events (Page 25) [1].

Wiring Steps:

1. Locate TB3 on the main controller board (Page 93) [1].

2. Connect the BMS monitoring points to the desired relay: Alarm (Form C), Supervisory (Form A), or Trouble (Form A or C) (Page 4, 25) [1].

3. Ensure all relay circuits are connected only to power-limited sources (Page 92) [1].

4. Verify the load does not exceed the contact rating of 24 VDC at 1 A resistive (Page 25) [1].

For protocol-based integration instead of dry contacts, the system supports the SA-FSB Communication Bridge to convert panel data to serial or Ethernet protocols for a BMS (Page 251) [1].
