How To Apply A PoE Temperature Adjust To Your Room Alert 3S or 12S

Using a Room Alert 3E monitor? Please click here for the appropriate FAQ.

Typically, when your Room Alert 3S or 12S runs on PoE (Power over Ethernet), it generates some additional heat, which can be difficult to dissipate in the unit’s small enclosure. The Apply PoE Temperature Adjust option, located in the Room Alert Monitor Sensor Settings, automatically adjusts for this heat difference.
