Limitations And Warranty - Honeywell ADEMCO VISTA Series Installation And Setup Manual

While this System is an advanced design security system, it does not offer guaranteed protection against burglary, fire or other
emergency. Any alarm system, whether commercial or residential, is subject to compromise or failure to warn for a variety of
reasons. For example:
•
Intruders may gain access through unprotected openings or have the technical sophistication to bypass an alarm sensor or
disconnect an alarm warning device.
•
Intrusion detectors (e.g., passive infrared detectors), smoke detectors, and many other sensing devices will not work without
power. Battery-operated devices will not work without batteries, with dead batteries, or if the batteries are not put in properly.
Devices powered solely by AC will not work if their AC power supply is cut off for any reason, however briefly.
•
Signals sent by wireless transmitters may be blocked or reflected by metal before they reach the alarm receiver. Even if the
signal path has been recently checked during a weekly test, blockage can occur if a metal object is moved into the path.
•
A user may not be able to reach a panic or emergency button quickly enough.
•
While smoke detectors have played a key role in reducing residential fire deaths in the United States, they may not activate or
provide early warning for a variety of reasons in as many as 35% of all fires, according to data published by the Federal
Emergency Management Agency. Some of the reasons smoke detectors used in conjunction with this System may not work are
as follows. Smoke detectors may have been improperly installed and positioned. Smoke detectors may not sense fires that start
where smoke cannot reach the detectors, such as in chimneys, in walls, or roofs, or on the other side of closed doors. Smoke
detectors also may not sense a fire on another level of a residence or building. A second floor detector, for example, may not
sense a first floor or basement fire. Finally, smoke detectors have sensing limitations. No smoke detector can sense every kind
of fire every time. In general, detectors may not always warn about fires caused by carelessness and safety hazards like smoking
in bed, violent explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits, children playing
with matches, or arson. Depending on the nature of the fire and/or location of the smoke detectors, the detector, even if it
operates as anticipated, may not provide sufficient warning to allow all occupants to escape in time to prevent injury or death.
•
Passive Infrared Motion Detectors can only detect intrusion within the designed ranges as diagrammed in their installation
manual. Passive Infrared Detectors do not provide volumetric area protection. They do create multiple beams of protection, and
intrusion can only be detected in unobstructed areas covered by those beams. They cannot detect motion or intrusion that takes
place behind walls, ceilings, floors, closed doors, glass partitions, glass doors, or windows. Mechanical tampering, masking,
painting or spraying of any material on the mirrors, windows or any part of the optical system can reduce their detection ability.
Passive Infrared Detectors sense changes in temperature; however, as the ambient temperature of the protected area
approaches the temperature range of 90° to 105°F (32° to 40°C), the detection performance can decrease.
•
Alarm warning devices such as sirens, bells or horns may not alert people or wake up sleepers if they are located on the other
side of closed or partly open doors. If warning devices are located on a different level of the residence from the bedrooms, then
they are less likely to waken or alert people inside the bedrooms. Even persons who are awake may not hear the warning if the
alarm is muffled by noise from a stereo, radio, air conditioner or other appliance, or by passing traffic. Finally, alarm warning
devices, however loud, may not warn hearing-impaired people.
•
Telephone lines needed to transmit alarm signals from a premises to a central monitoring station may be out of service or
temporarily out of service. Telephone lines are also subject to compromise by sophisticated intruders.
•
Even if the system responds to the emergency as intended, however, occupants may have insufficient time to protect themselves
from the emergency situation. In the case of a monitored alarm system, authorities may not respond appropriately.
•
This equipment, like other electrical devices, is subject to component failure. Even though this equipment is designed to last as
long as 10 years, the electronic components could fail at any time.
The most common cause of an alarm system not functioning when an intrusion or fire occurs is inadequate maintenance. This alarm
system should be tested weekly to make sure all sensors and transmitters are working properly. The security keypad (and remote
keypad) should be tested as well.
Wireless transmitters (used in some systems) are designed to provide long battery life under normal operating conditions. Longevity
of batteries may be as much as 4 to 7 years, depending on the environment, usage, and the specific wireless device being used.
External factors such as humidity, high or low temperatures, as well as large swings in temperature, may all reduce the actual battery
life in a given installation. This wireless system, however, can identify a true low battery situation, thus allowing time to arrange a
change of battery to maintain protection for that given point within the system.
Installing an alarm system may make the owner eligible for a lower insurance rate, but an alarm system is not a substitute for
insurance. Homeowners, property owners and renters should continue to act prudently in protecting themselves and continue to
insure their lives and property.
We continue to develop new and improved protection devices. Users of alarm systems owe it to themselves and their loved ones to
learn about these developments.
