Concord 4 User Manual 85
• If intruders have the technical means of bypassing, jamming, or disconnecting
any or all parts of the system.
• If power to sensors is disconnected or inadequate.
• If freeze, flood, or any environmental sensors are not located in areas where
the specific condition can be detected.
• If smoke does not reach a smoke sensor. For example, smoke sensors
cannot detect smoke in chimneys, walls, roofs, or smoke blocked by a closed
door. Sensors may not detect smoke on building levels different from their
installed location. Sensors may not warn in time when fires are caused by
smoking in bed, explosions, improper storage of flammables, overloaded
electrical circuits, or other hazardous conditions.
• If telephone lines are out of service. Telephone lines are also vulnerable to
compromise by any of several means.
Inadequate maintenance is the most common cause of alarm failure. Therefore,
test your system once each week to verify sensors, sirens, and phone
communication are all working correctly.
Although having an alarm system can make you eligible for reduced insurance
premiums, the system is no substitute for insurance.
WARNING: Security systems and devices cannot compensate you for like or
property losses.
