Environmental Monitoring with Relays (RSO)
Geist Environmental Monitor with Relays (RSO) - The solution for Server Room Environmental Monitoring
Monitoring the environment within the server room is fast becoming a major concern for server room managers. They face the daily task of keeping servers cool enough to perform optimally in order to reduce enegry wasted by overcooling. To succeed in this delicate balancing act, server room managers must collect strategic environmental data and have a rapid means to respond to changes in conditions. The Environmental Monitor with Relays (RSO), from Geist, provides server room managers with the information and tools needed to minimise excess cooling and maximise uptime. Remote environmental sensors are monitored and alarmed based on user defined thresolds. Relay control actions are configured to respond to conditions which are outside acceptable ranges. Facility managers can circumvent overheating through event trigger actuation of air conditioners, vents or sirens for audible alarming. These simple and timely precautions optimise energy efficiency.
