WARNING

THE LIMITATIONS OF THIS ALARM SYSTEM

Ihlle this system is an advanced deeign security system, if ties not otter guaremeed protection against Wrglary,

fire or other emergency. An alarm system, whather commercial or reektenfial, is subject to compromise or failure

to warn for a number of reasons. For ese~le:

Intruders may gain acceas through unprotected o~nings or have the technical aophisticetion to bypass an

alarm censor or d-nnm an abrm wami~ device.

Intrusion detectors (e.g. paesive infrared detecfom), smoke detectors, and many other eensing devices wilt not -

work wtihout power. Battery operated devices will not work without batteries, wth dead batteries, or t the

batteries

are not M in propew. Devices powered solely by AC till not work if their AC power supply is cut off for

any reason, howaver briefly.

Signals sent by wireless tranemiftere mey be blomed or raflecfed by metal before they reach the alarm

receiver.

Evan if the signal path has been recently checked during a weekly lest, blockage can occur Ka metal object is

roved into the path.

A ueer may not be able to reach a panic or emergency button quic~y enough.

While smoke detacfofe have played a key role in reducing residanfial fire deaths in the United States, they may

not acfiiate or provtie early warning for a variety of

reasonsinasmanyaa 350/0of all fires, acmrdi~ to data

published by the Federal Emergency Management Agency. Some of the raasone smoka detectors used in

conjunction with this System may not work are as folbws. Smoke detectors may have been impmperly installed

and posfioned. Srrwke detectors may not Sense fires that start where smoke Mnnot reach the detectors, such

se in chimneye, in walls, or roofs, or on fhe other side of closed doors. Smoke deteaors also may not sense a fire

on another level of a resideme or build!ng. A aemnd floor detector, for exampla, may Mt sense a first floor or

baaement fire. Moreover, smoke detectors have sensing timtiwlons. No emcke detector can sense every kind of

fire every time. In general, detectors may not shays warn abOuf fires caused by Carelesenese and safety hemrds

tike smoking in bed, violant explosions, escaping gas, improper storage or flammable materials, overbaded

electrical circuits, children playing with matches, or arson. Depending on the nature of the fire and/or the

focafion of the smoke detectors, the detector, evan if if operatea as anticipated, may not provide sufficient

warning to allow all occupants to escape in time to prevent inju~ or death.

Passive Infrared Mofiin Detedore can only detect infnssbn wfihin the deaigtsad ranges ae diagramed in their

installation manual. Passive Infrared Detectors do nof provide volumetric area protection. They do create

mffiple baams of protection, and infusion can only be detected in unobstnmted areas covered by the beams.

They cannot detect motion or infNsion that takes place behind walls, ceifings, floors, cloeed doors, glass

patitions, glass doors, or windows. Mechanial tampering, masking, pairn!ng or spraying of any rfmterial on the

mirrors, windows or any part of the optical system cn reduce their detection tifiiy. Passive Infrared Detectors

sense changea in temperature; however, as the ambient temperature of the protacted area approached the

temperature range of 90° to 150°F, the detecfiin performance can decreaee.

Afarm warning devices such as sirens, hlla or horns may not alert people or wake up sleepers who are focated

on the other side of a closed or partly open doors. If warning device eoursf on a dtierent level of the residence

fmm the bedmonw, then they are less likely to waken or alen people inside the bedrooms. Even persons who

are awake may not hear the warning if the alarm ie muffle by noise from a stereo, air wndifioner or other

appfiancea, or by passing traffic. Finally, alarm warning devtis, however loud, may not warn heann~impaired

~ople or waken deep sleepers.

Telephone tines needed to transmi alarm signals from a premises to a central morrionng station maybe out of

service or tem~rarily out of service. Telephone fines are also subject to mmpmmiee by Wphisficeted infNdare.

Even if the system responds to the emergency ae intended, however, owpenfs may have insufficient time to

protect themselves fmm the emergency situation. In the case of a monitored alarm system, authorities may not

resfmnd appropriately,

Thie equipment, lie other electrical devtis, is su@ect to component failure. Even though this equipmant is

designed to Iaat as bng as 10 years, the electronic mmponems muld fail at any time.

he most common cause of an alarm system not functioning when an intNsion or fire occurs is inadequate

aintenawe.

This alarm system should be teetad weekly to make sure all sensors are wotilng properly.

stalling an alarm system may make ona ehgible for lower insurance rates, but an alarm system is not a subsfiiute

r insurance. Homeownem, property owners and renters should continue to act pmdently in protecting

,emsewes and continue 10 insure their fives and pmperfy.

re mntinue to develop new and improvad pmtecfion devices.

Users of alarm eysfeme owe it to themseMes and

eir loved ones to learn about these developmems.
