Additional information


Nundnet NU49165FB uses 304 stainless steel that has excellent resistance to a wide range of atmospheric environments and many corrosive media. It is subject to pitting and crevice corrosion in warm chloride environments and to stress corrosion cracking above about 60°C. It is considered resistant to potable water with up to about 200 mg/L chlorides at ambient temperatures, reducing to about 150 mg/L at 60 °C.


Nundnet NU4165FB equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. This device is designed to provide the reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.

ADA Compliance

This Compliance is critical to ensure that two users cannot enter through the turnstiles `side by side’ thereby gaining unauthorized access. While as the DDA compliant wheelchair accessible Lanes is 900 – 940mm thereby allows passage for wheelchair users and those with other impairments or who are in need of assistance.
