EA200 / EA400 Output (Alarm) Connections
1. For all alarm loops to be controlled by the EA200 / EA400, install all required wiring
from alarm loops to the EA200 / EA400 mounting location.
2. Determine the alarm-to-Zone allotment to be used with the EA200 or EA400 being
installed. See the table above in EA200 / EA400 Sensor Connections.
3. Connect the alarm loop leads to the Terminal Block Adapter. Attach the adapter to
terminals C and either NC or NO on the appropriate circuit board header connector.
See Figures 8 and 9.
Figures 8 and 9 show typical alarm loop wiring configurations. Figure 8 shows an
alarm loop where alarm power is derived from the alarm loop. Figure 9 shows an
alarm loop where alarm power is derived from the power supply feeding the EA200 /
EA400.
In both cases, the configuration shown uses the Alarm Output Relay mode set to
“DE-ENERGIZED” (alarm sent when relay energizes and closes).
To configure for ENERGIZED operation, the Zone should be programmed for
ENERGIZED, and the NC terminal of the output relay should be used instead of NO.
4. Repeat the above step for each alarm loop.
