Designed specifically to assist with computer room temperature and environment monitoring in multiple locations simultaneously.
Room Alert 4ER offers an easy to use web browser interface for settings changes and viewing real-time temperature and sensor status from anywhere. Mount the Room Alert 4ER in a server rack with the 1U 19" rack mount kit (assembled) or use without the rack mount in other environments where monitoring physical conditions is desired.
- Easy Ethernet ‘Plug and Play’ setup for remote temperature and environment monitoring from anywhere.
- Includes 2 Digital Temperature Sensors (1 internal, 1 external, with 1 open port).
- Use with AVTECH's sensors for Digital Temperature, Digital Outdoor Temperature, Digital Fluid Temperature or Digital Temperature & Humidity.
- Includes 1 Switch Sensor Channel for connection of an external switch sensor such as power, flood, smoke, motion, air flow, room entry, panic buttons or others.
- Includes 1 port for connection of AVTECH's Light Tower w/Audio or Relay Switch sensor.
- Includes the ability to ping up to 8 devices on the network and alarm if they do not respond.
- Includes PUSH Technology and SNMP Trap & Query compatibility.
