CLIMAX TECHNOLOGY CO., LTD. No. 258, Sinhu 2nd Rd., Neihu District 114, Taipei City, Taiwan ( R.O.C.) Federal Communications Commission Authorization and Evaluation Division Equipment Authorization Branch 7435 Oakland Mills Road Columbia, MD 21046 Applicant’s declaration concerning RF Radiation Exposure We hereby indicate that the product Product description: Wireless Indoor Siren Model No: SRx-xxxxx Series (x=0~9, A~Z or blank) The equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. The integral antennas used for this transmitter must not be co-located or operating in conjunction with any other antenna or transmitter within the host device. A safety statement concerning minimum separation distances from enclosure of the Product : Outdoor Bellbox will be integrated in the user’s manual to provide end-users with transmitter operating conditions for satisfying RF exposure compliance. The appropriate information can be drawn from the test report no: W6M21503-14875-C-1 and the accompanying calculations. Company: CLIMAX TECHNOLOGY CO., LTD. Address: No. 258, Sinhu 2nd Rd., Neihu District 114, Taipei City, Taiwan ( R.O.C.) Date: 2015-04-01 Signature

Registration number: W6M21503-14875-C-1 FCC ID: GX9SR 3.2 Equivalent isotropic radiated power FCC Rule: 15.247(b)(3) EIRP = max. conducted output power + antenna gain (Directional gain) EIRP = 8.66 dBm + 0.72dBi = 9.38 dBm Limit: EIRP = +36 dBm for Antenna gain <6dBi Test equipment used: ETSTW-RE 055 3.3 RF Exposure Compliance Requirements FCC OET Bulletin 65 Edition 97.01 determines the equations for predicting RF fields and applicable limits. The prediction for power density in the far-field but will over-predict power density in the near field, where it could be used for walking a “worst case” or conservative prediction.
