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.
