Environment Controller 2450
Sierra Monitor’s Facility Environment Controller 2450 is an electronic, microprocessor-based system designed to manage the heating, ventilating and air conditioning (HVAC) controls, environmental alarms, and manage rigorous personnel safety requirements of controlled environment vaults (CEVs) and walk-in cabinets. Recognized as the standard of the industry, the Model 2450 has been installed in over 90% of all new CEVs deployed since its introduction.
The Model 2450 employs lead/lag and demand logic to control two air conditioners. Application specific software is used to collect data from various sensor inputs to make continuous, real-time control logic and alarm decisions. The results of the logic are used to operate control outputs, send alarms to telephone company systems, and display status and alarm conditions on the front panel of the controller.
The Model 2450 also monitors CEVs for the presence of combustible and toxic gases and automatically initiates ventilation when an alarm threshold is exceeded. Alarm thresholds are automatically reduced from unoccupied levels to OSHA defined, occupied levels to further ensure personnel safety.
