Site Design

Transceiver hub locations are the most critical element of establishing a reliable and cost

effective wireless Messenger network. An insufficient quantity of hubs or incorrectly

positioned hubs may result in 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

In the United States, the Messenger system uses a license-free shared-space radio frequency

bandwidth between 902MHz and 928MHz. The Saflok Messenger devices employ at least

50 different frequencies and “frequency hop” to avoid jamming and collisions in this “shared

space.” All Saflok Messenger equipped units will have the following label. Do not remove

the label from the enclosures that it is attached to.

Changes or modifications not expressly approved by Computerized Security

Systems, Inc. could void the user's authority to operate the equipment.

This product needs to be kept 20cm from the body due to RF exposure.
