As this input is used to reset the Alarm annunciation within the detector, it is
suggested that for safety reasons the switch be protected by key access in some
manner to prevent accidental de-activation of alarms.
The digital inputs from up to 20 ECO detectors can be physically connected to the
same switch connection.
