4.4.1. Functional Overview
If the PPM level for any zone exceeds its designated spill, leak, or evacuate thresholds, an alarm condition
will be created. Once the MZ monitor completes a measurement cycle in the affected zone the alarm
condition will be indicated. At that time the red ALARM LED on the MZ monitor will glow. Additionally, an
external alarm device may activate and an audible alarm may sound if those features have been enabled.
The next time the RD polls the affected monitor its red ALARM LED will glow. Additionally, an external
alarm device may activate and an audible alarm may sound if those features have been enabled.
