The Underground Silent Zone Generator is mounted on a vehicle or piece of machinery and is connected by an interface cable to an Underground controller. The Underground Silent Zone Generator is mounted on the vehicle or machinery in an area near where the operator would normally be while operating the machinery. 1.1 Theory of Operation The function of the Underground Silent Zone Generator is:  To transmit a 73 kHz “Silent Zone” field around a small portion of the vehicle or piece of machinery in which the operator is allowed to work or enter as part of his normal activities. The Underground Silent Zone Generator is connected to a HazardAvert™ Underground Controller which generates a 73 kHz signal for creating a Silent Zone around the area of a machine where the operator is located. This 73 kHz signal is connected to the Silent Zone Generator via a wire bundle. Inside the Underground Silent Zone Generator is a wire/ferrite radiator element to which the 73 kHz signal is connected. The 73 kHz signal passing through this wire/ferrite radiator element generates a “Silent Zone” electromagnetic field which encompasses only the small area of the machine in which the operator can be during operation. The operator is required to wear a Personal Alarm Device (PAD) which is another component of the HazardAvert™ system which detects and responds to the presence of 73 kHz fields. As long as the operator is within this “Silent Zone” his PAD will know he is within a defined area and not alarm. If the operator exits this Silent Zone area, his PAD will function to alert him and other machines equipped with the HazardAvert™ system of his proximity to dangerous conditions due to his distance from machine or vehicle hazards. 1.2 Frequency of Operation The Underground Silent Zone Generator will transmit on a frequency of 73 kHz. 1.3 Label Information The Underground Silent Zone Generator label is located on the face of the unit. A picture of the Strata label is below: Confidential Patent #’s 7,420,471 5,939,986 and 6,810,353 Patent Pending Page 4 of 6 Strata Proximity Systems Underground Silent Zone Generator Users Manual v1.0 Confidential and Proprietary December 12, 2011 The Strata label defines the model and serial number of the Underground Silent Zone Generator also MSHA and Commonwealth of Pennsylvania information. 1.3.1.1 MSHA Blasting Distance MSHA has published Program Policy Letter P11-V-07 concening Two Way Communications and Blasting Circuits. SPS magnetic field generators produce a magnetic field that at 100 kHz or .1000 MHz does not achieve the Critical H Field until 1.42 m with a blasting cap having a pickup area of 10 sq. meters. SPS magnetic field generators are safe to 1.42 m from the blasting caps. SPS does recommend a minimum distance of 25’ as a precaution. 1.3.1.2 Pennsylvania Blasting Distance At this date, Pennsylvania has not made a recommendation or statement concerning surface systems. 1.4 FCC Information The FCC ID for the Underground Silent Zone Generator is ZQ3-SPS-USZON. When configured by Strata for underground use, the device complies with Part 15 of the FCC Rules. Operation is subject to the following conditions: (1) This device may not cause harmful interference. (2) This…

Response to ATCB Comments ZQ3-SPS-USZON 1 Washington Laboratories, Ltd. 7560 LINDBERGH DRIVE GAITHERSBURG, MD 20879 (301) 216 - 1500 FAX # (301) 216 - 1590 January 16, 2012 Mr. Richard Fabina American Telecommunications Certification Body Inc. 6731 Whittier Ave McLean, VA 22101 RE: Comments of January 11, 2012 APPLICATION: ATCB011650; ZQ3-SPS-USZON for Strata Proximity Systems Dear Mr. Fabina: Below are the comments that you have provided regarding the application for certification referenced above. Our responses to those comments are in bold italic. Many responses refer you to additional exhibit(s) which has been uploaded to the application folder at the ATCB website. Thank you for your attention. Please feel free to contact us for any additional information that you may require. Regards, James Ritter EMC Compliance Engineer WLL Project: 12037 1) Please either provide AC line conducted emissions tests with this device being powered by the AC power lines or provide justification on why these tests are not required. Section 15.207( c) of the FCC Rules states “Devices that include, or make provisions for, the use of battery chargers which permit operating while charging, AC adapters or battery eliminators or that connect to the AC power lines indirectly, obtaining their power through another device which is connected to the AC power lines, shall be tested to demonstrate compliance with the conducted limits.” Section 2.2 of the submitted test report shows the EUT being powered from support equipment which is being powered by the AC mains network. R. The manufacturer has advised us that this equipment is for mining operations and will not be connected directly or indirectly to the public mains, only independent powered equipment such as vehicle batteries. The setup referred to in Section 2.2 of the test report showing the device connected to a lab DC power supply was used only for lab testing purposes and does not reflect the actual final field power installation configuration.
