3.7.5 Alarm Relay Output Configuration
The 6888Xi has two dry contact Form-C alarm relay output signals that can be configured in
multiple modes through the 6888Xi keypad display or the 375/475 Field Communicator. A list
of modes is shown in Table 3-3. Each alarm relay output can be configured separately and one
or all modes can be turned on in any combination.
If the 6888Xi is configured with the optional Flame Safety Interlock or for Traditional
Architecture, Alarm 2 is preconfigured with "Heater Relay" and prewired to either the AC Relay
Board or DR Board. In this condition the relay configuration cannot be changed to any other
setting. If changes are attempted to be made, the 6888Xi will respond with an “Access
Restricted” warning. If the 6888Xi is not configured with the optional Flame Safety Interlock,
"Heater Relay" is not valid and cannot be chosen for Alarm 2.
