Description of the EUT The Smiths Detection (Watford) Automatic Detection Reporting System (ADRS) Radio Modem enables a collection of Fixed Site Chemical Detectors (FSD) to be combined into a wireless network reporting to a single location to provide centralized recording of FSD data and control and monitoring of the FSDs. Each FSD is connected to a Radio Modem (outstation) which communicates with another Radio Modem (Base Station) connected to a controller Laptop. The Radio Modems also have built in Global Positioning System (GPS) receivers that are activated at startup to obtain position co-ordinates. The ADRS unit operates in the frequency sub-band of 902MHz to 928MHz and can be powered by internal batteries (6vdc) or powered externally (12vdc – 30vdc). The frequencies tested were 902MHz, 915MHz and 927MHz. The EUT was as received with no external visible signs of damage and was of production quality. 2.2. EUT’s Modes of Operation All tests are performed with Frequency modulation producing a maximum of 1.6W radiated power unless stated otherwise. Standard test mode waveform profile is 16KF1D. 2.3.

TESTS Report No.: EM09042278a Page: 5 of 86 Product: ADRS Radio Modem Issue Date: May 13 th 2010 Model No.: RM013 Issue No.: 5 3.1. RF Conducted Power The testing was performed in accordance with FCC CFR47 Part 15:247b (3). 3.2. SAR Evaluation Refer Annex A for Radiated Exposure Levels report. The RF power output was set to maximum power output (CW) and was measured at the antenna port connected directly to a Spectrum Analyser, at the lower, middle and upper frequencies . 3.3. RF Conducted Power Test Results The RF power output was set to maximum power output (CW) and was measured at the antenna port connected directly to a Spectrum Analyser, at the lower, middle and upper frequencies. The results are given in Table 1 and pages 8 – 9. These tests were carried out on the 26 th November 2009.
