3. Security and Insurance. Regardless of its capabilities, no Mircom System is a substitute for
property or life insurance. Nor is the system a substitute for property owners, renters, or other
occupants to act prudently to prevent or minimize the harmful effects of an emergency
situation. Building automation systems produced by the Mircom Group of Companies are not
to be used as a fire, alarm, or life-safety system.
NOTE TO INSTALLERS:
All Mircom Systems have been carefully designed to be as effective as possible. However,
there are circumstances where they may not provide protection. Some reasons for system
failure include the following. As the only individual in contact with system users, please bring
each item in this warning to the attention of the users of this Mircom System. Failure to
properly inform system end-users of the circumstances in which the system might fail may
result in over-reliance upon the system. As a result, it is imperative that you properly inform
each customer for whom you install the system of the possible forms of failure:
4. Inadequate Installation. All Mircom Systems must be installed in accordance with all the
applicable codes and standards in order to provide adequate protection. National standards
require an inspection and approval to be conducted by the local authority having jurisdiction
following the initial installation of the system and following any changes to the system. Such
inspections ensure installation has been carried out properly.
5. Inadequate Testing. Most problems that would prevent an alarm a Mircom System from
operating as intended can be discovered by regular testing and maintenance. The complete
system should be tested by the local authority having jurisdiction immediately after a fire,
storm, earthquake, accident, or any kind of construction activity inside or outside the premises.

10
Warranty and Warning Information
The testing should include all sensing devices, keypads, consoles, alarm indicating devices
and any other operational devices that are part of the system.
NOTE TO USERS:
All Mircom Systems have been carefully designed to be as effective as possible. However,
there are circumstances where they may not provide protection. Some reasons for system
failure include the following. The end user can minimize the occurrence of any of the following
by proper training, testing and maintenance of the Mircom Systems:
6. Inadequate Testing and Maintenance. It is imperative that the systems be periodically
tested and subjected to preventative maintenance. Best practices and local authority having
jurisdiction determine the frequency and type of testing that is required at a minimum. Mircom
System may not function properly, and the occurrence of other system failures identified below
may not be minimized, if the periodic testing and maintenance of Mircom Systems is not
completed with diligence and as required.
7. Improper Operation. It is important that all system users be trained in the correct operation
of the alarm system and that they know how to respond when the system indicates an alarm.
A Mircom System may not function as intended during an emergency situation where the user
is unable to operate a panic or emergency switch by reason of permanent or temporary
physical disability, inability to reach the device in time, unfamiliarity with the correct operation,
or related circumstances.
8. Insufficient Time. There may be circumstances when a Mircom System will operate as
intended, yet the occupants will not be protected from the emergency due to their inability to
respond to the warnings in a timely manner. If the system is monitored, the response may not
occur in time enough to protect the occupants or their belongings.
9. Carelessness or Safety Hazards. Moreover, smoke detectors may not provide timely
warning of fires caused by carelessness or safety hazards such as smoking in bed, violent
explosions, escaping gas, improper storage of flammable materials, overloaded electrical
circuits or children playing with matches or arson.
10. Power Failure. Some Mircom System components require adequate electrical power supply
to operate. Examples include: smoke detectors, beacons, HVAC, and lighting controllers. 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 Mircom Systems or other electronic
equipment. After a power interruption has occurred, immediately conduct a complete system
test to ensure that the system operates as intended.
11. Battery Failure. If the Mircom System or any device connected to the system operates from
batteries it is possible for the batteries to fail. Even if the batteries have not failed, they must be
fully charged, in good condition, and installed correctly. Some Mircom Systems use
replaceable batteries, which have a limited life-span. The expected battery life is variable and
in part dependent on the device environment, usage and type. Ambient conditions such as
high humidity, high or low temperatures, or large temperature fluctuations may reduce the
expected battery life. Moreover, some Mircom Systems do not have a battery monitor that
would alert the user in the event that the battery is nearing its end of life. Regular testing and
replacements are vital for ensuring that the batteries function as expected, whether or not a
device has a low-battery monitor.
12. Physical Obstructions. Motion sensors that are part of a Mircom System must be kept clear
of any obstacles which impede the sensors’ ability to detect movement. Signals being
communicated by a Mircom System may not reach the receiver if an item (such as metal,
water, or concrete) is placed on or near the radio path. Deliberate jamming or other
inadvertent radio signal interference can also negatively affect system operation.

11
Warranty and Warning Information
13. Wireless Devices Placement Proximity. Moreover all wireless devices must be a minimum
and maximum distance away from large metal objects, such as refrigerators. You are required
to consult the specific Mircom System manual and application guide for any maximum
distances required between devices and suggested placement of wireless devices for optimal
functioning.
14. Failure to Trigger Sensors. Moreover, Mircom Systems may fail to operate as intended if
motion, heat, or smoke sensors are not triggered.
a. Sensors in a fire system may fail to be triggered when the fire is in a chimney, walls, roof,
or on the other side of closed doors. Smoke and heat detectors may not detect smoke
or heat from fires on another level of the residence or building. In this situation the
control panel may not alert occupants of a fire.
b. Sensors in a nurse call system may fail to be triggered when movement is occurring
outside of the motion sensors’ range. For example, if movement is occurring on the other
side of closed doors or on another level of the residence or building the motion detector
may not be triggered. In this situation the central controller may not register an alarm
signal.
15. Interference with Audible Notification Appliances. Audible notification appliances may be
interfered with by other noise sources such as stereos, radios, televisions, air conditioners,
appliances, or passing traffic. Audible notification appliances, however loud, may not be heard
by a hearing-impaired person.
16. Other Impairments. Alarm notification appliances such as sirens, bells, horns, or strobes
may not warn or waken a sleeping occupant if there is an intervening wall or door. It is less
likely that the occupants will be alerted or awakened when notification appliances are located
on a different level of the residence or premise.
17. Software Malfunction. Most Mircom Systems contain software. No warranties are provided
as to the software components of any products or stand-alone software products within a
Mircom System. For a full statement of the warranties and exclusions and limitations of
liability please refer to the company’s standard Terms and Conditions and Warranties.
18. Telephone Lines Malfunction. Telephone service can cause system failure where telephone
lines are relied upon by a Mircom System. Alarms and information coming from a Mircom
System may not be transmitted if a phone line is out of service or busy for a certain period of
time. Alarms and information may not be transmitted where telephone lines have been
compromised by criminal tampering, local construction, storms or earthquakes.
19. Component Failure. Although every effort has been made to make this Mircom System as
reliable as possible, the system may fail to function as intended due to the failure of a
component.
20. Integrated Products. Mircom System might not function as intended if it is connected to a
non-Mircom product or to a Mircom product that is deemed non-compatible with a particular
Mircom System. A list of compatible products can be requested and obtained.
