The Xi has two dry contact Form-C alarm relay output signals that can be configured in eight different modes through the Xi keypad display or the 375/475 Field Communicator. A list of possible configurations is shown in Table 3-1. Each alarm relay output can be configured separately.

If the Xi is configured with the optional Flame Safety Interlock, Alarm 2 is configured with "Heater Relay" and prewired to the AC Relay Board. In this condition the relay configuration cannot be changed to any other setting. If the Xi is not configured with the optional Flame Safety Interlock, "Heater Relay" is not valid and cannot be chosen for Alarm 2.
