Out of Warranty Repairs
Kantech will at its option repair or replace out-of-warranty products which are returned to its factory according to the following conditions. Anyone
returning goods to Kantech must first obtain an authorization number. Kantech will not accept any shipment whatsoever for which prior authorization
has not been obtained. Products which Kantech determines to be repairable will be repaired and returned. A set fee which Kantech has predetermined
and which may be revised from time to time will be charged for each unit repaired. Products which Kantech determines not to be repairable will be
replaced by the nearest equivalent product available at that time. The current market price of the replacement product will be charged for each
replacement unit.
WARNING - PLEASE READ CAREFULLY
Note to Installers
This warning contains vital information. As the only individual in contact with system users, it is your responsibility to bring each item in this warning to
the attention of the users of this system.
System Failures
This system has been carefully designed to be as effective as possible. There are circumstances, however, involving fire, burglary, or other types of
emergencies where it may not provide protection. Any access control system of any type may be compromised deliberately or may fail to operate as
expected for a variety of reasons. Some but not all of these reasons may be:
•
Inadequate Installation
An access control system must be installed properly in order to provide adequate protection. Every installation should be evaluated by a security
professional to ensure that all access points and areas are covered. Locks and latches on windows and doors must be secure and operate as intended.
Windows, doors, walls, ceilings and other building materials must be of sufficient strength and construction to provide the level of protection expected.
A reevaluation must be done during and after any construction activity.
•
Criminal Knowledge
This system contains security features which were known to be effective at the time of manufacture. It is possible for persons with criminal intent to
develop techniques which reduce the effectiveness of these features. It is important that an access control system be reviewed periodically to ensure
that its features remain effective and that it be updated or replaced if it is found that it does not provide the protection expected.
•
Access by Intruders
Intruders may enter through an unprotected access point, circumvent a sensing device, evade detection by moving through an area of insufficient
coverage, disconnect a warning device, or interfere with or prevent the proper operation of the system.
•
Power Failure
Control units, readers, exit detectors and many other security devices require an adequate power supply for proper operation. If a device operates from
batteries, it is possible for the batteries to fail. Even if the batteries have not failed, they must be charged, in good condition and installed correctly. If a
device operates only by AC power, any interruption, however brief, will render that device inoperative while it does not have power. Power interruptions
of any length are often accompanied by voltage fluctuations which may damage electronic equipment such as an access control system. After a power
interruption has occurred, immediately conduct a complete system test to ensure that the system operates as intended.
•
Motion Detectors - Request to Exit
Motion detectors can only detect motion within the designated areas as shown in their respective installation instructions. Motion detectors do not
provide volumetric area protection. They have multiple beams of detection and motion can only be detected in unobstructed areas covered by these
beams. They cannot detect motion which occurs behind walls, ceilings, floor, closed doors, glass partitions, glass doors or windows. Any type of
tampering whether intentional or unintentional such as masking, painting, or spraying of any material on the lenses, mirrors, windows or any other part
of the detection system will impair its proper operation. Passive infrared motion detectors operate by sensing changes in temperature. However their
effectiveness can 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. Some of these heat sources could be heaters, radiators, stoves, barbeques, fireplaces, sunlight, steam vents, lighting
and so on.
•
Component Failure
Although every effort has been made to make this system as reliable as possible, the system may fail to function as intended due to the failure of a
component.
•
Inadequate Testing
Most problems that would prevent a system from operating as intended can be found by regular testing and maintenance. The complete system should
be tested weekly and immediately after a break-in, an attempted break-in, a fire, a storm, an earthquake, an accident, or any kind of construction activity
inside or outside the premises. The testing should include all sensing devices, keypads, consoles, alarm indicating devices and any other operational
devices that are part of the system.
