3.0 Installation
3.1 Parts of the Enclosure
The OpenBAS-HV-RF433R consists of two modules: the RF module and the I2C module. The
RF module receives information wirelessly from the OpenBAS-HV-WLSTH thermostat. The
I2C module is connected to any OpenBAS NX controller, or an OpenBAS-NWK-ETH3
controller through the I2C connection.
The RF module and the I2C module communicate with each other over wires (shown in
section 4.2 on page 16). The maximum wiring distance between the RF module and the I2C
module is 49 feet (15 m).
Each module consists of a circuit board and an enclosure.
Figure 1 Parts of the enclosure
Note: Installation of OpenBAS-HV-RF433R controllers should be in accordance with
the Canadian Electrical Code or the National Electrical Code, and comply with all
local regulations. Final acceptance is subject to the Local Authority Having
Jurisdiction (AHJ).

3.3 Installing Accessories
3.3.1 I2C Connector
Connect the I2C port of the I2C module (shown in Figure 4) to the I2C port of an OpenBAS
controller. The maximum length of the connection is 1 foot (30 cm).
The OpenBAS-HV-RF433R receives power from the OpenBAS controller that it is connected
to.
Attention: This job must be performed only by a certified technician as dangerous
voltages might be present inside of the enclosure.
Always disconnect the power before installing accessories.
Note: When connecting the I2C ports on 2 devices, make sure to connect pin 1 on the
first device to pin 1 on the second device. Pin 1 is marked by a dot or a “1”.

6.0 Warranty and Warning Information
WARNING!
Please read this document CAREFULLY, as it contains important warnings, life-safety, and
practical information about all products manufactured by the Mircom Group of Companies,
including Mircom and Secutron branded products, which shall include without limitation all fire
alarm, nurse call, building automation and access control and card access products
(hereinafter individually or collectively, as applicable, referred to as “Mircom System”).
NOTE TO ALL READERS:
1. Nature of Warnings. The within warnings are communicated to the reader out of an
abundance of caution and create no legal obligation for Mircom Group of Companies,
whatsoever. Without limiting the generality of the foregoing, this document shall NOT be
construed as in any way altering the rights and obligations of the parties, governed by the legal
documents that apply in any given circumstance.
2. Application. The warnings contained in this document apply to all Mircom System and shall
be read in conjunction with:
a. the product manual for the specific Mircom System that applies in given circumstances;
b. legal documents that apply to the purchase and sale of a Mircom System, which may
include the company’s standard terms and conditions and warranty statements;
c. other information about the Mircom System or the parties’ rights and obligations as may
be application to a given circumstance.
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.

20
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.
