The Secondary or Auxiliary Unit is the secondary relay station for the AerosphereTM carbon dioxide monitoring system. Gas detection levels for all sensors, alarm statuses, temperature, time and date are all visible on a white-on-black LCD display.
This unit can be installed as a repeater for the master unit, displaying the level and alarm state of the master at a remote location. Up to three independent auxiliary monitoring stations, each with its own sensor, LCD readout and alarm, can be linked to one central monitor.
The auxiliary unit should be mounted in a position convenient for visibility. It may not necessarily be near the source of gas you wish it to monitor, but could be mounted in a different room.
