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:
• If sirens or horns are placed outside the hearing range of people in remote areas of the building or in areas that
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 be detected.
• If the AC power supply is OFF and the back up battery is either missing or dead, sensors do not detect intrusion.
• Smoke detectors cannot detect smoke in chimneys, walls, or roofs, or smoke blocked by a closed door. They may
not detect smoke or fire on a level of the building different from the one on which they are located. Smoke
detectors may not be able to 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 that all system components are working properly. Although having a security
system may 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.
Fire Safety and Evacuation
Residential fire is a leading cause of accidental death. Most fire related deaths occur at night when occupants suffocate in their
sleep from smoke and toxic gases, rather than from burns. To help reduce this risk, the following program should be
implemented.
1.
Minimize fire hazards. Smoking in bed, cleaning with flammable liquids such as gasoline, leaving children
home alone, and using unsafe holiday decorations are some of the common causes of household fire.
2.
Install a fire alarm system. The primary purpose of this system is to protect lives by giving the earliest possible
warning of danger.
3.
A smoke detector should be provided to protect each sleeping area in a home.
4.
Practice an escape plan. Because there may be very little time between detection of a fire and the time it becomes
deadly, it is important that every family member understands how to quickly evacuate according to the plan.
5.
Plan both primary and alternate escape routes. Since stairwells and hallways may be blocked during a fire,
exiting through a bedroom window must be a part of the escape plan. If the sleeping area is above the ground
floor, install a means of safely descending outside the building if one does not already exist.
6.
As a part of this plan, all family members should arrange to meet at a location away from the house (such as a
neighbor's house) so you will know that everyone is accounted for.
7.
If it is determined that the alarm was accidentally sounded, the bell should be silenced, the detectors reset, and
your security company notified immediately that there is no emergency situation.

Note:
A smoke detector should be located on each story including basements, but excluding crawl spaces and unfinished
attics. Locate smoke detectors between sleeping areas and family living areas.
