ADEMCO 7720PLUS Installation Instructions Manual page 37

This equipment has been tested to FCC requirements and has been found acceptable for use. The FCC
requires the following statement for your information:
This equipment generates and uses radio frequency energy and if not installed and used properly, that is, in
strict accordance with the manufacturer's instructions, may cause interference to radio and television
reception. It has been type tested and found to comply with the limits for a Class B computing device in
accordance with the specifications in Part 15 of FCC Rules, which are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
•
If using an indoor antenna, have a quality outdoor antenna installed.
•
Reorient the receiving antenna until interference is reduced or eliminated.
•
Move the receiver away from the transmitter.
•
Move the antenna leads away from any wire runs to the transmitter.
•
Plug the transmitter into a different outlet so that it and the receiver are on different branch circuits.
If necessary, the user should consult the dealer or an experienced radio/television technician for additional
suggestions.
The user or installer may find the following booklet prepared by the Federal Communications Commission
helpful:

This booklet is available from the U.S. Government Printing Office, Washington, DC 20402. Stock No.
The user shall not make any changes or modifications to the equipment unless authorized by the Installation
Instructions or User's Manual. Unauthorized changes or modifications could void the user's authority to
operate the equipment.
TO THE INSTALLER
Regular maintenance and inspection (at least annually) by the installer and frequent testing by the user are
vital to continuous satisfactory operation of any alarm system.
The installer should assume the responsibility of developing and offering a regular maintenance program to
the user as well as acquainting the user with the proper operation and limitations of the alarm system and
its component parts. Recommendations must be included for a specific program of frequent testing (at least
weekly) to insure the system's proper operation at all times.
THE LIMITATIONS OF THIS RADIO COMMUNICATIONS SYSTEM
While this 900 MHz Long Range Radio communications system is part of an advanced and sophisticated
security system, it does not offer guaranteed protection against burglary or fire, nor does it guarantee
communication of burglary or fire warning signals to a central station. Any alarm system, or any
communications system, whether commercial or residential, is subject to compromise, or failure to warn, for
a variety of reasons. Examples of some of these reasons are:
•
Intruders may gain access through unprotected openings or have technical sophistication to bypass an
alarm sensor, and then disconnect an alarm communicating radio transmitter.
•
Signals sent by 900 MHz radio transmitters may be blocked by metal, mountains, hills, foliage and other
natural and man made obstructions before they are received by a master receiving station or sent to a
central station. Even a path previously verified as acceptable may periodically change its characteristics.
•
Long-range radio communication transmitters will not work without power. Radio transmitters require a
battery to work properly in the absence of A.C. power. A weak or dead battery, or improperly installed
batteries may prevent these devices from functioning properly if A.C. power is disrupted for any reason.
