Installation and Setup Guide
• 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.
