WARNING: Please read carefully
Note to Installers
This warning contains vital information. For the sole individual in contact with the user’s
system, it is their responsibility to address each item in this warning for the attention of the
users of this system.
System Failures
The system has been carefully designed to be as eective as possible. However, there are cir-
cumstances, including re, burglary or other emergencies where it will not be able to provide
protection.
Any alarm system can be deliberately compromised or fail to operate for a number of rea-
sons, some of which may include:
Improper Installation
A security system must be properly installed to provide adequate protection. The equipment
must not be installed where it will be exposed to moisture.
or splashing. Each installation should be evaluated by a security professional to ensure that all
points and access areas are covered. Locks and latches on windows and doors must be secure
and operate as designed. Windows, doors, walls, ceilings and other materials must possess
sucient strength and construction to provide the expected level of protection. A reassess-
ment must be performed during and after any construction activity. An assessment by the
police or re service is highly recommended if this service is available.
The equipment must be installed in an environment with temperatures between 0ºC and
70ºC.
Criminal Knowledge and Sabotage
This system contains security features that were known to be eective at the time of manu-
facture. It is possible for people with criminal intent to develop techniques which reduce the
eectiveness of these features. It is very important that the security system is reviewed perio-
dically, to ensure that its features remain eective and that they are upgraded or replaced if
they are found not to provide the expected protection.
Access by Intruders
Intruders can enter through an unprotected access point, circumvent a sensing device, evade
detection by moving through an area of insucient coverage, disable a warning device, inter-
fere with or prevent proper operation of the system.
Power Failure
Control units, intrusion detectors, smoke detectors and many other security devices require
an adequate power supply for proper operation. If a device is battery operated, it is possible
for the batteries to fail. Even if the batteries have not failed, they must be charged, in good
condition and properly installed. If a device operates on AC power, any interruption, even
a slow one, will render the device inoperative while without power. Power interruptions of
any duration are often accompanied by voltage uctuations which can damage electronic
equipment such as security systems. After a power interruption occurs, immediately conduct
a complete system test to ensure that the system is functioning as intended.
Compromised Wireless Devices
Signals will not be able to reach the receiver under all circumstances, which include metallic
objects placed nearby or deliberate interference.
Failure of Replaceable Batteries
Expected battery life is a function of the environment, usage and type of device. Environ-
mental conditions such as exaggerated humidity, high or low temperatures, or varying
amounts of temperature uctuations may reduce the life of the battery. Regular testing
and maintenance will keep the system in good working condition.
System Users
It is very important that all users of the system are trained in the correct operation of the
alarm system and know how to respond to an alarm.
Smoke Detectors
Smoke detectors, which are a part of the system, may not properly alert occupants of a re
for a number of reasons, some of which are as follows: Smoke detectors may have been
incorrectly installed or located. Smoke may not be able to reach the smoke detectors, such
as when the re is in the replace, walls or ceilings, or on the other side of closed doors.
Smoke detectors do not can detect smoke from res on other levels of the residence. Each
re is dierent in the amount of smoke produced and the speed of the re. Smoke detec-
tors cannot detect all types of res equally well. Smoke detectors cannot provide early
warning of res caused by carelessness or lack of safety such as smoking in bed, violent
explosions, gas leaks, improper storage of combustion materials, overloaded electrical
circuits, playing with matches, or arson. Even if the smoke detector operates as designed,
there may be circumstances where there is insucient warning time to allow occupants to
escape in time to avoid injury or death.
Motion Detectors
Motion detectors can only detect movement within the designated areas, as shown in the
respective installation instructions. They do not discriminate between intruders and/or
inhabitants of the premises or residence, nor do they provide volumetric area protection.
They have multiple detection beams and motion can only be detected in unobstructed
areas covered by these beams. They cannot detect movement behind walls, ceilings, oors,
closed doors, glass partitions, glass doors or windows. Any kind of sabotage, intentional or
unintentional, will impair their proper operation. Passive infrared motion detectors opera-
te by detecting temperature changes. However, their eectiveness may be reduced when
the ambient temperature rises near or above body temperature or if there are intentional
or unintentional sources of heat in or near the detection area. Sources of heat may include
heaters, radiators, cookers, grills, replaces, sunlight, etc.
Warning Devices
Warning devices such as sirens, bells, horns, or strobes may not alert or awaken someone
if there is an intervening door or wall. If warning devices are located on a dierent level of
the residence or premises, it is less likely that occupants can be warned or awakened. Audi-
ble warning devices can be interfered with by other noise sources such as stereos, radios,
televisions, air conditioners, etc.
Audible warning devices, even loud ones, may not be heard by people with hearing impair-
ments.
Telephone Lines
If telephone lines are used to transmit alarms, they may be out of service or busy for some
time. Also an intruder can cut the line or sabotage its operation by more sophisticated
means which would be very dicult to detect.
Insucient Time
There may be circumstances when the system is functioning as designed, and even the
occupants will not be protected from emergencies, due to their inability to respond to war-
nings in a timely manner. If the system is supervised, the response may not occur in time to
protect the occupants or their belongings.
Component Failure
Despite all eorts at system reliability, the system may fail to work properly. function, due
to the failure of a component.
Incorrect Test
Most problems/failures in an alarm system can be found by regular testing and maintenan-
ce. The entire system should be tested weekly and immediately after an intrusion, attemp-
ted intrusion, re, storm, earthquake, accident or any kind of construction activity inside or
outside the premises. The test should include all devices that are part of the system, such
as sensors, keypads, sirens, etc.
Safety and Insurance
Despite its capabilities, an alarm system is not a substitute for property or life insurance.
Nor is an alarm system a substitute for property owners, tenants, or other occupants to
act prudently to prevent or minimise the harmful eects of an emergency situation.
