SM/LCM Sensors and Indicators 
The SM/LCM housing contains a sensor and two indicators which provide the same 
indications whether the module is a local control module or a full status monitor. 
Note:  Refer to Status Monitor/Local Control Module Description (on page 6) for an 
illustration of the housing and indicators. 
The functions of the sensor and indicators are described in the following table.

LIGHT SENSOR 
This ambient light sensor sends a trap to the status monitoring 
and control software indicating that the node housing is open.

OFF - Normal operation. 
BLINK (slow) - Minor alarm.  One or more of the measured 
parameters is over threshold limit.  Blinks approximately once 
per second.
