Attenuation of cabling between two nodes (fiber-optic circuits are point-to-point) must not
exceed the Maximum attenuation, specified below.
To determine attenuation:
NOTE: DAA-75 products do not have an onboard battery charger. A UL 864 listed power supply
rated for the battery requirements of the specific application is suitable for charging purposes.
