AVTECH Room Alert 3S RA3S-ES0-BAS Network Environmental Monitor with Ethernet/PoE
The AVTECH Room Alert 3S is a compact environmental monitor for technical rooms, telecom cabinets, small data centers, offices, warehouses and other spaces where temperature and other critical environmental conditions need to be monitored.
This model includes an internal temperature sensor, Ethernet with PoE connectivity, an integrated web interface and support for alerts and SNMP integration. It is an economical network environmental monitoring solution, especially suitable for locations with limited space.
Compact monitoring for critical environments
Room Alert 3S allows real-time ambient temperature monitoring and can add up to two additional environmental conditions through its external sensor ports. When defined thresholds are exceeded, the system can send alerts to help prevent failures, equipment damage or operational interruptions.
- Internal ambient temperature sensor.
- RJ-45 Ethernet connection with PoE support.
- AVTECH 5V power adapter included.
- Integrated web interface for configuration and local monitoring.
- Support for SNMP v1, v2c and v3.
- Compatible with AVTECH digital sensors through the RJ-11 port.
- Ideal for small spaces, technical cabinets and equipment rooms.
Expansion with external sensors
The device includes one digital port for an external sensor or accessory and one switch sensor port. To monitor humidity and dew point, a compatible digital temperature and humidity sensor must be used, sold separately.
