NOTICE
●Commission and setup the device prior to mounting.
●To power on the sensor module, connect it to a surface mount powered by
USB type C, PoE, or AC/DC 12...24 V.
Mounting location
●The devices are suitable for drywall mounting, conduit box mounting and surface mounting.
●Recommended height: 1.5 m (4 feet) above the floor. If the recommended height cannot be met, it should
not be lower than 0.9 m (3 feet).
●Do not mount the devices in recesses, shelves, behind curtains or doors, or above or near heat sources.
●Avoid direct solar radiation and drafts.
●Avoid unheated (uncooled) building area such as outside walls.
●Seal the conduit box or the installation tube if any, as air currents can affect sensor readings.
●Adhere to allowed ambient conditions.
●Devices should be mounted at least 5 m (16 feet) away from operable windows, air filters, and fresh air
