|Module Relay Alarm Supervision and Trouble|
The 4010-9803 Relay Module connects to the SFI/O board of a 4010 FACP with a ribbon harness (733-952). The relay module provides connections to different devices through three dry relay contacts providing Alarm, Supervisory, and Trouble reporting. If a CPU failure occurs, the relay module’s trouble output transfers. See Figure 1 below for connector locations.
