0.5 SAFETY NOTICES AND ADMONISHMENTS
This document contains safety notices in accordance with appropriate standards. In the interests of conformity
with the territory standards for the country concerned, the equivalent territorial admonishments are also shown.
Any installation, adjustment, maintenance and repair of the equipment must only be carried out by trained,
authorized personnel. At all times, personnel must comply with any safety notices and instructions.
Specific hazards are indicated by symbol labels on or near the affected parts of the equipment. The labels
conform to international standards, are triangular in shape, and are colored black on a yellow background. An
informative text label may accompany the symbol label.
Hazard labeling is supplemented by safety notices in the appropriate equipment manual. These notices contain
additional information on the nature of the hazard and may also specify precautions.
Note: The grantee is not responsible for any changes or modifications not expressly approved by the party
responsible for compliance. Such modifications could void the user’s authority to operate the equipment.
For compliance with the general population RF exposure limits, each individual antenna used for this
transmitter must be installed to provide a separation distance greater than 67.2cm or more from all persons
during normal operation and must not be co-located with any other antenna for meeting RF exposure
requirements.
Warning Notices:
Caution: The user is cautioned that changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this
device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This
equipment should be installed and operated with a minimum distance of 20cm between the radiator and your
body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

1 GENERAL INFORMATION
The CriticalPoint Antenna Monitoring System consists of the Main Control Unit (MCU) and monitoring tags
which are easily installed on the service antennas. The system utilizes RFID (Radio Frequency Identification)
technology, that is incorporated into the DAS (Distributed Antenna System), to monitor the link status of the
entire passive network. It can report the status of any individual antenna link in real time via an easy to use GUI
and transmit the overall alarm information through Form C dry contacts. This system will satisfy AHJ
requirements for monitoring service antennas as part of the overall System Component Failure alarming
requirements. The system can also enormously increase the efficiency and accuracy of monitoring a passive
antenna system, as well as troubleshooting of the passive network.
Main Features
•Monitor In-building status in real time for all passive components, antenna coax, and service antennas
•Report overall status through dry contact alarming, login to identify alarms from individual antenna paths
•Supports up to 20dB cable loss from Main Control Unit (MCU) to Antenna
•Supports up to 50 antennas
•Supports Monitoring UHF/T band, 700/800MHz systems
•Monitor VHF system via external combining
•Supports Form C dry contact alarms
•MCU is housed in a NEMA 4 enclosure
•Low Power Consumption

2 EQUIPMENT DESCRIPTION
2.1 MCU (MAIN CONTROL UNIT) BLOCK DIAGRAM
Figure 2: MCU (Main Control Unit) Block Diagram
MCU generates a pilot signal at 910MHz or 915MHz, combines the RF signal from BDA/Signal Booster through
the combiner and transmit the combined signal to each of the antenna, the RFID tags in the antenna will be
energized by the pilot signal and send a response back to the MCU.

3.1 WARNINGS AND ALERTS
Radio Frequency Energies
There may be situations, particularly for workplace environments near high-powered RF sources, where
recommended limits for safe exposure of human beings to RF energy could be exceeded. In such cases,
restrictive measures or actions may be necessary to ensure the safe use of RF energy.
High Voltage
The equipment has been designed and constructed to prevent, as far as reasonably practicable danger. Any
work activity on or near equipment involving installation, operation or maintenance must be, as far as
reasonable, free from danger.
Where there is a risk of damage to electrical systems involving adverse weather, extreme temperatures, wet,
corrosive or dirty conditions, flammable or explosive atmospheres, the system must be suitably installed to
prevent danger.
Protective Earthing
Equipment provided for the purpose of protecting individuals from electrical risk must be suitable for the
purpose and properly maintained and used.
Handling Precautions
This covers a range of activities including lifting, lowering, pushing, pulling, carrying, moving, holding or
restraining an object, animal or person from the equipment. It also covers activities that require the use of force
or effort, such as pulling a lever, or operating power tools.
Where some of the abovementioned activities are required, the equipment must be handled with care to avoid
being damaged.
Electrostatic Discharge (ESD)
Observe standard precautions for handling ESD-sensitive devices. Assume that all solid-state electronic
devices are ESD-sensitive. Ensure the use of a grounded wrist strap or equivalent while working with
ESD-sensitive devices. Transport, store, and handle ESD-sensitive devices in static-safe environments.

Use addressable antenna:
⚫IXD-360H04YJN-ADR: Low profile, Ceiling Mount, 380-2700MHz, H Pol, 360°, 2.0/2.2/4.5dBi
⚫IXD-360H04MJN-ADR: Low profile, Ceiling Mount, 698-2700MHz, H Pol, 360°, 2.2/3.5/4.5dBi
Or put the RFID tags on the antenna emission surface:
⚫These tags should be installed on in-building services antennas and the gain for these antennas shall not
