The Room Alert 12SR is AVTECH's rack mounted mid-range environment monitor in our Room Alert PRO line, offering the highest security features such as HTTPS, TLS and SNMP v3. Like our Room Alert 12ER, this model monitors temperature plus up to 8 more environment conditions of your choice including an analog (0-5VDC) input. It also offers an additional dedicated relay port to toggle low-voltage electrical devices. When conditions exceed your thresholds, Room Alert notifies you right away so you can act quickly. Send email and text messages right from the device. Trigger the warning LEDs and siren sound on a Light Tower. Pair with (or other compatible platforms) for even more alerting capabilities.

It Includes ALL of the following:

  • Secure data transfer options include HTTPS / SSL Web Interface, SSL / TLS Email Support, SNMP v1/v2c/v3, 2048-bit encryption and SSL Push to Room Alert Account
  • Easy Ethernet ‘Plug & Play’ setup for immediate IT & facilities environment monitoring.
  • Includes a built-in sensor for digital temperature and “PUSH” technology.
  • Includes Power over Ethernet (PoE) and external Digital Active Power w/Temperature Sensor.
  • Includes ports for 3 digital sensors and 4 switch sensors or dry contacts, as well as additional ports to connect 0-5V analog sensor, low voltage relay,and Light Tower & Relay Adapter (LTA).
  • Offers advanced alerting by email, email-to-SMS, SNMP, webpage update and more.
  • Use Room Alert 12S’s built-in web server, Account (included), local Room Alert management software (included), or SNMP to monitor across your network
  • The Room Alert 12S package allows real-time sensor status, data logging, graphing, advanced alerting, Fahrenheit/Celsius, high/low watermarks and much more.

Easy Monitoring

Room Alert 12SR can easily monitor environments such as phone or wiring closets, critical rack cabinets and larger computer rooms or data centers. Since Room Alert 12SR is connected via Ethernet and does not require a host PC for operation, it can be located anywhere an Ethernet connection is available. This monitor is Power over Ethernet (PoE) enabled allowing it to be placed anywhere PoE Ethernet is available. Sensors can be run inside a rack cabinet, air vent, sub floor or other location. Room Alert 12SR will help to protect valuable IT equipment and minimize downtime if a disaster should occur. It can also be used to manage utility use by monitoring power consumption, allowing possibilities to reduce energy costs.
