failed connections, while an overabundance of hubs creates excessive Ethernet drops and installation

costs.

The Messenger wireless devices are capable of indoor ranges in excess of a 40 meter radius. However,

building architecture and construction materials employed will dramatically influence the locations of the

transceiver hubs. Flooring plays an especially significant role; steel decking will result on transceiver

hubs being located on every floor while other construction techniques will reduce the number of required

transceiver hubs to every second or third floor. Actual on-site range studies shall be performed in

determining the actual hub locations. Consult with your local Saflok representative on scheduling a site

survey.

System Protocol / FCC Requirements

This 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. These limits are designed to provide 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 the instructions, may cause harmful interference

to radio communications. However, there is no guarantee that interference will not occur in a particular

installation. If this equipment does cause harmful interference to radio or television reception, which can
