FCC ID: Q6KAT170503A IC ID: 5043A-AT170503A PRODUCT CHANGE INFORMATION:

In order to better support Law Enforcement Customers, 3SI Security Systems is seeking the FCC and ISED approval to extend the beacon transmitter operating frequencies to include all channels as listed in 47CFR 95.2163(b) Currently, 3SI operates the beacon transmitter on a single frequency of 216.475 MHz which is listed as channel #50 in the rule quoted above. This frequency will continue to be supported. 3SI Security Systems will continue to use the same signaling scheme for the transmitter. Hence, the emission ID for the beacon transmitter listed on the original FCC and ISED Grants remains unchanged. No hardware changes were required to support the additional channels. Firmware needed to be modified. The firmware revision used for C2PC testing is:

13.2.41741 The product label content related to regulatory compliance remains unchanged from the original filing. We hereby attest that the above declarations are correct. ______________________________ Date 2020-05-29

This letter outlines changes introduced by 3SI Security Systems to already certified module identified as:

FCC ID: Q6KAT170503A IC: 5043A -AT170503US 1. 216.475 MHz beacon transmit antenna optimization. Evaluation of the integrated product revealed that the flexible tab originally reserved as the ground plane extension was practically neutral to the modem antenna radiated performance. 3SI placed a trace antenna on this tab that exhibits increased radiation efficiency, as compared to the originally filed discrete component antenna. 3SI reduced the conducted power to this antenna to remain within limits of the originally filed ERP data, thus reducing the transmitter current consumption and extending the useful battery life. The ERP and spurious emissions were evaluated by SGS Laboratory in Suwannee, GA and found compliant. 2. A new host PCB was added as an option for the module to expand the functionality. The new PCB contains a battery charging circuitry, relays to control external sensors or alarms, and the I2C controller to communicate with the module. Radiated and conducted emissions were verified by SGS Laboratory in Suwannee, GA and found compliant. 3. Since the new host described above introduced a ground plane near the 2.4 GHz antenna, WiFi and Bluetooth radiated performance was evaluated by by SGS Laboratory in Suwannee, GA and found compliant. 3SI Security is seeking approval of the above changes. Supporting EMC Reports are enclosed. Sincerely, _______________________ Brandon Cromer Contact Name:
