Typical applications
Large data center — dense temperature-humidity measurement in hot/cold aisles over two separate CAN chains.
Many dry contacts — UPS, cooling, generator, fire panel and breaker status signals.
Automatic control of cooling, fans or alarm systems via isolated outputs.
Distributed enterprise — central SNMP/NMS monitoring of multiple sites, LTE backup link.
Disaster prevention — instant notification and automatic action on water leak or smoke.

Details
Extension unit that adds +8 analog sensor ports to Vutlan master units over CAN bus. Sensors are auto-detected; up to 24 VT408 units can be chained on one CAN line, with bus length up to 225 m. Used when the master unit runs out of ports or sensors are clustered in a remote rack.
Details
High-accuracy temperature and humidity sensor that daisy-chains over CAN bus. Connected in series on a single cable for multi-point measurement at rack fronts/backs, hot/cold aisles or around a room. Each parameter is a separate element in the web interface; dew point is calculated in the interface.
Details
Photoelectric smoke detector connecting to the analog port of Vutlan master units. Ceiling-mounted; up to 10 detectors in a chain are monitored as one element. Delivers early smoke warnings from server rooms, cabinets and technical spaces via SNMP, e-mail or SMS.
Details
4G LTE modem that plugs into the modem slot of Vutlan master units. Provides SMS alarm sending/receiving and Ethernet access over LTE; if the LAN link fails it switches to LTE automatically so notifications keep flowing. VT7670E for European bands, VT7670G for worldwide use.
DetailsNetwork monitoring and fault management platform that integrates the ENTIRE HiPath / OpenScape product family — including OpenScape Voice — plus hardware/software from other vendors. Runs on the OpenScape Common Management Platform and pairs with fault + performance + user + accounting + deployment modules.
