Monitors phone or wiring closets, critical rack cabinets and facilities of all types, in real time. Since Room Alert 3E is connected via Ethernet and does not require a host PC for operation, it can be located anywhere an Ethernet connection is available. Room Alert 3E is Power over Ethernet (PoE) enabled which allows it to be placed anywhere PoE Ethernet is available (i.e. power source not required). Sensors can be run inside a rack cabinet, air vent, sub floor or other location. Room Alert 3E will help to protect valuable IT equipment or other property and minimize downtime if a disaster should occur.
Room Alert 3E can also be easily used in non-technology environments residential and commercial buildings, restaurants, warehouses, greenhouses and much more.
The AVTECH Room Alert 3E is the monitoring base unit and has one built-in temperature sensor. You can add further external sensors in order to sense a wide variety of different environmental factors in your data center.

|Digital Sensors Digital sensor ports only support connecting digital sensors. Digital sensors measure within a range of values, like a temperature range.||1||1||2||2||3||3||3||3||8||8|
|Switch Sensors Switch sensor ports only support connecting switch sensors. Switch sensors only measure one of two states, the normal state and the alarm state. Take the smoke sensor as an example, it has a normal state which indicates no significant smoke is present and an alarm state that indicates that a significant amount of smoke is present perhaps indicating a fire.||1||1||1||1||4||4||4||4||16||16|
|Analog Sensors Analog sensors provide values as voltages between 0-5VDC. Common analog sensors include current loops and extreme high and low temperature sensors. The Room Alert 3 WiFi and Room Alert 3E do not support analog sensors, but you can buy the Digital Temperature & Analog Sensor to add support at the cost of one of your digital sensor ports.||0||0||1||1||1||1||1||1||2||2|
|Light Tower & Relay Ports A port for connecting a Light Tower to your Room Alert. There are two port types. The Room Alert 4E / 4ER has a six terminal port to plug in the AVTECH External Light Tower. The Room Alert 12E, 12ER, 32E and 32W all have RJ11 connectors dedicated to the light tower. But the light tower must be the model with the built-in light tower adapter. The Room Alert 3E also supports the light tower but does not have a dedicated port. You must use one of your digital sensor ports to connect the light tower.||0||0 ||1||1||1 ||1 ||1 ||1 ||2 ||2 |

The Room Alert 12E, 12ER, 32E and 32W all have dedicated ports for connecting the Light Tower with Adapter. On the Room Alert 3E you need to use one of the digital sensor ports. You can buy a light tower with integrated light tower adapter for use with the Room Alert 3E, 12E, 12ER, 32E and 32W.
What is RoomAlert.com?
RoomAlert.com is a cloud based service for monitoring Room Alert monitors and newer Axis cameras combined with a download area for device firmware updates and Device ManageR software and plugins. The service has a number of different subscription levels, Lite, Personal, Professional and Enterprise. The level of your subscription dictates what level of access to the RoomAlert.com service you receive. If you require a level of access afforded by a higher level of subscription, you can upgrade your subscription to the higher level at any time.
Device ManageR Software
Device ManageR software is a solution for discovery, management, logging, graphing and alerting of your Room Alert monitoring estate. It runs as a Windows service and automatically discovers AVTECH hardware and Axis IP cameras across your network, allowing users to be informed immediately when environmental thresholds are exceeded or when events occur. Device ManageR has a web browser interface allowing users to view and manage any or all units on your network, graph and log sensor data in real-time or over specified date ranges or send out alerts if an issue arises.
The Device ManageR software also has a number of plugins available like the Window Plug-In Bundle or Unix/Linux Bundle. When used with Device ManageR, they allow shutdown, reboot and/or log off of systems remotely and perform commands or scripted actions when alerts are detected or events occur as well as scheduled reports and data management tasks.
Manage in the cloud with RoomAlert.com
RoomAlert.com gives you worldwide visibility of your environment data, with built-in alerting, logging, reporting and management. You'll no longer need to guess what your data center temperature is, you'll be able to see in real time exactly what the temperature is from any web connected device like your smart phone or tablet. All Room Alert monitors send your data readings straight up to RoomAlert,com where it is stored, logged and, if necessary, triggers an alarm for you.
