8.3 Environmental Monitoring
The Environmental Monitoring Device (EMD), model B090-EMD, can be connected to any Console Server
serial port and each Console Server can support multiple EMD’s. Each EMD has one temperature and
one humidity sensor and one general purpose status sensor which can be connected to a smoke
detector, water detector, vibration or open-door sensor.
The B095-004/003 Console Server models have an internal temperature sensor.
Using the Management Console, Administrators can view the ambient temperature and humidity and
set the EMD to automatically send alarms progressively from warning levels to critical alerts.
