FCC Statement

Federal Communication Commission Interference Statement
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 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.

Antenna trace design

Trace design

Only trace designs approved by the module original grantee or through permissive change can be used by the host manufacturer.
Different antenna lengths and trace layouts are considered a different antenna type and should be reviewed to ensure compliance with the FCC and ISED regulation rules.

Any change to the trace design must contact wecare@alarm.com
Verification must be conducted and the results shall not exceed the certificates to ensure identical antenna design is applied to subsequent integration and end product production.

Test procedures for design verification

RF transmission lines, such as those that connect from the RF pin to the antenna or antenna connector, must be controlled at characteristic impedance of 50 Ohm. Use calculation tools to verify the correct impedance.
In general, the impedance of RF signal is determined by the Permittivity (ER) of PCB material, line width (W), ground clearance (S), height of reference ground plane (H) and other factors.
If you are not sure how to verify it, please contact wecare@alarm.com.

Production test procedure to ensure compliance.

Before you place the host device on the market:

Set transmission in the supported modulation mode, band and Channel.

Verify RF tuned-up power through conducted measurement and spurious emission.

The KDB guidance 558074 and 789033 can be followed to obtain the measurement results. Under no circumstance the test result violate the FCC/ISED regulation limits and the original modular approval.

Information on test modes and additional testing requirements
This module has been approved under stand-alone configuration. OEM integrator has be limited the operation channels in channel 1-11 for 2.4GHz band. The separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093/RSS-102 and different antenna configurations

The information on how to configure test modes for host product evaluation for different operational conditions for a stand-alone modular transmitter in a host, versus with multiple, simultaneously transmitting modules or other transmitters in a host can be found at KDB Publication 996369 D04. OEM integrator is still responsible for testing their end product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).

IMPORTANT NOTE: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC/ISED authorization is no longer considered valid and the FCC/IC No. cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC/ISED authorization.

Additional testing, Part 15 Subpart B and ICES-003 disclaimer
Appropriate measurements (e.g. Part 15 Subpart B compliance) and if applicable additional equipment authorizations (e.g. SDoC) of the host product to be addressed by the integrator/manufacturer. This module is only FCC/ISED authorized for the specific rule parts 15.247, 15.407/RSS-247 listed on the grant, and the host product manufacturer is responsible for compliance to any other FCC/ISED rules that apply to the host product as being Part 15 Subpart B/ICES-003 compliant. If any changes or modifications need to be made to the integrated product, such as adding or adjusting the antenna or cable, follow the guidelines provided by Grantee. For further assistance, please contact: wecare@alarm.com
