SYSTEM 238 Installation Manual
26
Intruders may gain access through unprotected openings or
have the technical sophistication to bypass an alarm sensor or
disconnect an alarm warning device.
Intrusion detectors, smoke detectors, and many sensing de-
vices will not operate without power. Devices powered by AC
will not work if their AC power supply is off for any reason and
their back-up batteries are missing, dead, or improperly in-
stalled.
Alarm warning devices such as sirens, bells, and horns may not
alert people or wake up sleepers if they are located on the other
side of closed or partly closed doors. If warning devices are on
a different level of the residence from the bedrooms, they are
less likely to waken or alert people inside the bedrooms.
Telephone lines needed to transmit alarm signals from a
premise to a central monitoring station may be out of service or
temporarily out of service. Telephone lines are subject to
compromise by sophisticated methods of attack.

While the SYSTEM 238 is an advanced design security system, it does
not offer guaranteed protection against burglary, fire, or other losses.
Any alarm system, whether commercial or residential, is subject to
compromise or failure-to-warn for a variety of reasons. These include:
THE LIMITATIONS OF YOUR ALARM SYSTEM
Smoke detectors used in conjunction with the alarm system
may not sense fires that start where smoke cannot reach the
detectors, such as chimneys, walls, or roofs, or on the other side
of closed doors. Smoke detectors also may not sense a fire on
another level of the residence or building. A second floor
detector, for example, may not sense a first floor or basement
fire. Finally, smoke detectors have sensing limitations. No
smoke detector can sense every kind of fire every time. In
general, detectors may not always warn you about fires caused
by carelessness and safety hazards, like smoking in bed,
violent explosions, escaping gas, improper storage of flam-
mable materials, overloaded electrical circuits, children playing
with matches, arson, etc.
The most common cause of an alarm system not functioning
properly when an intrusion or fire occurs is inadequate
maintenace. Your alarm system should be tested weekly to
make sure all sensors are operating properly. The SYSTEM
238 panel and keypads should also be tested.

Installing an alarm system may make you eligible for lower
insurance rates, but an alarm system is not a substitute for
insurance. Homeowners, property owners, and renters should
continue to insure their lives and property.
