Security System Limitations

Not even the most advanced security system can guarantee protection against burglary, fire, or environmental threats. All security systems are subject to possible compromise or failure-to-warn for a variety of reasons including, but not limited to, the following:

•If sirens or horns are placed outside the hearing range of people in remote areas of the building or in areas which are frequently closed off, they do not provide the intended protection.

•If intruders gain access through unprotected points of entry, the system does not detect their entrance.

•If intruders have the technical means of bypassing, jamming, or disconnecting all or part of the system, they are not detected.

•If the AC power supply is off and the backup battery is missing or dead, sensors do not detect intrusion.

•Smoke detectors cannot detect smoke in chimneys, walls, roofs, or smoke blocked by a closed door. They can not detect smoke or fire on a level of the building different from the one on which they are located. Smoke detectors can’t warn in time about fires started by explosions, improper storage of flammables, overloaded electrical circuits, or other types of hazardous conditions.

•If phone lines are out of service, reports from the security system to the security company cannot be sent. Telephone lines are vulnerable to compromise by several means.

Inadequate maintenance and failure to test are the most common causes of alarm failure. It is strongly recommended that you test your system once a week to be sure all system components are working properly.

Although having a security system can make you eligible for reduced insurance premiums, the system is no substitute for insurance. Warning devices cannot compensate you for loss of life or property.
