AVTECH’s Room Alert 4E/4ER is an economical environment monitor that meets more focused needs. It monitors your facility for temperature and up to 3 more environment conditions of your choice. Our standard package includes 1 external Digital Temperature Sensor.
Want to respond to alert conditions by turning electrical devices on and off? This model additionally features a dedicated custom port for AVTECH’s Relay Switch or Light Tower w/ Audio. No adapter is needed, which is easier on your budget!
The 4ER version has a removable rack mount and fits 1U of space in a server cabinet; the 4E version can hang from a ceiling or on a wall from its wall mount. One unit covers smaller spaces by itself; multiple can canvas larger areas. This unit is at home in small computer rooms and large data centers, modest storage spaces and sprawling warehouses alike!
