Information
Terms & Interpretation
In this document the term MGC System refers to all fire alarm, nurse call, and building
automation products manufactured by Mircom Group of Companies, Mircom Technologies
Ltd., MGC Systems Corp or subsidiaries and affiliates and includes specific systems such as
MiCare™, OpenBAS™, and FlexNet™. Moreover, the term MGC System extends to cover all
component parts and software used within such products.
Warning Please Read Carefully
All MGC Systems are subject to terms and conditions of sale as follows:
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 MGC
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.
System Failures
All MGC 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:
Inadequate Installation
All MGC 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.
Inadequate Testing
Most problems that would prevent an alarm a MGC 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. The testing should include all
sensing devices, keypads, consoles, alarm indicating devices and any other operational
devices that are part of the system.
IMPORTANT NOTE:
batteries, telephone lines, etc. are tested and examined on a regular basis to minimize system
failure.
End-users of the system must take care to ensure that the system,
24 (30)
Master Warranty and Warning Information
System Users
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 MGC 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.
Insufficient Time
There may be circumstances when a MGC 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.
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, children playing with matches or arson.
Power Failure
Some MGC 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 MGC 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.
Battery Failure
If the MGC 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.
MGC Systems with wireless transmitters use replaceable batteries. The system is designed
to provide several years of battery life under normal conditions. The expected battery life is a
function of 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. While each transmitting device has a low battery monitor which identifies when the
batteries need to be replaced, this monitor may fail to operate as expected. Regular testing
and maintenance will keep the system in good operating condition.
Physical Obstructions
Motion sensors that are part of a MGC System must be kept clear of any obstacles which
impede the sensors’ ability to detect movement. Signals being communicated by a MGC
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.
Moreover, MGC Systems may fail to operate as intended if motion, heat, or smoke sensors
are not triggered. 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; and, smoke and heat detectors may
25 (30)
Master Warranty and Warning Information
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.
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.
Other Impairments
Similarly, 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.
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.
Software
Most MGC Systems contain software. With respect to those products, MGC does not warrant
that the operation of the software will be uninterrupted or error-free or that the software will

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.
