Room Alert 3E is AVTECH’s most economical solution for “IT & Facilities Environment Monitoring, Alerting & More”. Room Alert 3E is designed specifically to assist with monitoring room temperature and other environmental conditions where a small footprint is needed, where access to electricity may not exist, when the investment cost needs to be minimal or deployment volume may be high. It is the least cost host for a Light Tower & Relay Adapter (LTA) that allows connection of an AVTECH Light Tower, Light Tower w/Audio or Relay Switch Sensor. Add a digital sensor and switch sensor of your choice to expand monitoring with an easy “click connect”. Room Alert 3E environment and IT monitoring is a PoE enabled device although if your network is not PoE, simply use the included power adapter and you are good to go.
