What it represents
Reports an ambient atmospheric condition relevant to equipment operation.
In a drafting package, connect this reference to the ambient sensor, location and measured parameter. The associated drawing should trace the environmental alarm or operating permission; the number identifies the role and does not specify the terminal arrangement, ratings or operating settings.
How to read it
- Identify the ambient sensor, location and measured parameter.
- Trace the environmental alarm or operating permission.
Information to show or reference
- Label the ambient sensor, location and measured parameter.
- Cross-reference the environmental alarm or operating permission.
- Identify the device tag, manual revision and logic drawing that define this implementation.
A distinction that matters
The number is a broad environmental function; the legend must identify humidity, smoke, gas or another actual parameter.
