Axonn Corporation AX630 Transmitter Users Manual RF Transmitter Installation Instructions The AX630 Transmitter is a member of our Spread Spectrum RF family of products. This transmitter should only be installed by qualified service personnel. The transmitter detects level, low battery or other data signals from the external binary inputs and broadcasts that data to the system's host receiver. MOUNTING LOCATION The AX630 Transmitter is a module as defined by the FCC and therefore must be mounted to another host device in order to function. NOTICE TO CUSTOMER Any Axonn customer incorporating the AX630 transmitter module into its own product must have an external notice affixed to its product. This notice must be placed in a conspicuous location and can use wording such as: “Contains FCC ID: L2VAX630” or “Contains Transmitter Module FCC ID: L2VAX630”. Any similar wording that expresses the same meaning may be used. INSTALLATION INSTRUCTIONS 1. Supply the transmitter with DC power by inserting a 3Volt battery into the battery holder on the customers host application circuit board. 2. The unit will come pre-programmed with Transmitter ID and Property Code. There will be no field programming of the unit. 3. When installing the AX630 you should avoid areas near screens, metal window frames, circuit breaker boxes, air conditioners and heaters if a suitable location for the unit may be found elsewhere. TESTING THE TRANSMITTER Following system installation, system testing is mandatory. This should be performed by locating the AX630 in its final location and powering up the unit. On initial power-up, the AX630 will send out RF messages every 4 seconds or more depending on programming. This will establish communications with the Host receiver and the information collected will then be used to judge system performance. FCC NOTICE The Model AX630 transmitter generates and uses radio frequency energy. If not installed and used in accordance with the manufacturer's instructions, it may cause interference to radio and television reception. The transmitter has been tested and found to comply with the specifications in Part 15 of FCC Rules for Spread Spectrum Intentional Radiators and FCC Part 15 Subpart C, Specifications. If this equipment causes interference to radio or television reception - which can be determined by turning the equipment on and off - the installer is encouraged to correct the interference by one or more of the following measures: 1) Reorient the antenna of the radio/television. 2) Connect the AC transformer to a different outlet so the control panel and radio/television are on different branch circuits. 3) Relocate the control panel with respect to the radio/television. If necessary, the installer should consult an experienced radio/television technician for additional suggestions, or send for the "Interference Handbook" prepared by the Federal Communications Commission.

L.L.C. 2021 Lakeshore Drive ∙ Suite 500 ∙ New Orleans, Louisiana 70122 ∙ (504) 282-8119 ∙ FAX (504) 304-2427 April 9, 2001 Federal Communicatio ns Commissio n Equipment Authorization Div ision 7435 Oakland Mills Road Columbia, MD 21046 Dear Sir or Madam: This letter is a follow-up to request that the attached filing (FCC ID L2VAX630) be submitted for modular approval. Prior discussion with the commission centered on the issue of shielding for a Part 15 modular application. Axonn has modified its design to include a shield to comply with FCC Public Notice DA 00-1407. The L2VAX630 has an attached shield that is similar in form and function to the shielding of OJM-TR-916-SC, which has receiv ed modular approval of the commission. Axonn L.L.C. appreciates the fact that the commission must maintain product integr ity w ithout giv ing one company a competitiv e adv antage ov er another company. In defense of Axonn’s modular application for the L2VAX630, the following is re-stated: 1. The dev ice incorporates the following harmonic suppression techniques: Surface mount and co-planar technology is used throughout the design, minimizing stray RF fields that launch electromagnetic waves. Nov el filter technology that prov ides guaranteed suppression of transmitter spurious products by design. Each circuit is statistically modeled using computer aided design techniques for 6-sigma repeatability with the tolerances of the low-cost components used. Innov ativ e signal generation techniques which utilize the power of Fourier analysis to suppress even-order harmonics in the generation of the transmitted signal. A self-contained, printed-circuit antenna is utilized to guarantee a stable output match to the final amplifier. The printed antenna dispenses with the variability of externally mounted alternativ es that could prov ide indeterminate terminations to the transmitter output. Indeterminate terminations cause reflections to the output circuitry of other transmitters, resulting in increased spurious products. 2. All data inputs are buffered. 3. The dev ice has its own power supply regulation. 4. The dev ice is a complete transmitter module, with its own reference oscillator and printed antenna. All connectors are for power supply data inputs. 5. The dev ice was submitted as a stand-alone unit for testing. The conducted emissions requirements do not apply as this will be a battery-powered unit. Other points of discussion concerning modular transmitter approvals are covered in other portions of this application. Axonn L.L.C appreciates the approach that the commission has taken in regards to Part 15 modular approval, in that the modular approval guidelines allow rapid deployment of wireless technology w hil e maintain ing product integr ity. Best Regards, David Alley Axonn L.L.C.

In support of its request for confidentiality, the following is stated. The subject device employs the emerging technology, spread spectrum. Research and development of this technology for commercial applications by the public is being explored by a number of entities and companies. The developer of the technology used to produce the instant device, Axonn Corporation, has emerged as one of the industry leaders and has gained a competitive edge over its competition by employing creative and functional circuit designs and production methods. This competitive position has been carefully cultivated and promoted to the benefit of Axonn and its licensees of its technology. Axonn Corporation foresees that this Transmitter shall only be purchased and installed by professionals. We do not currently foresee ourselves making this product available over-the-counter to the average consumer. Axonn Corporation has obtained licenses and continues to file for patents to protect each new generation of its spread spectrum technology. However, as the commission is aware, the time period for grant of such protection does not accommodate the need to bring devices to the marketplace. Accordingly, Axonn Corporation desires to bring its devices to the marketplace without creating undue risk of duplication of technical, proprietary design. Best Regards, David Alley Axonn L.L.C.

FCC ID: L2VAX630 SECTION 6 RF EXPOSURE INFORMATION FCC ID: L2VAX630 6.1 RF Safety Requirements to 2.1091 for Mobile Transmitters The EUT is being submitted for modular approval. However, due to the design of the transmitter and low duty cycle the manufacturer only expects the EUT to be used in mobile environment. The unit under evaluation has an integral antenna of –1.0 dBi gain with a measured output power output of 0.059 Watts at the antenna terminals. Taking into consideration the gain of the antenna, the corrected EIRP is 46.9 mW. The MPE calculations are shown as follows: The limits for this unit (uncontrolled exposure) are 1.0 mW/cm 2 . Taking the RF Density Field Equation: S = EIRP (mW)/(4πR 2 ) and solving for Distance R R = SQRT(EIRP (mW)/(S4π)) Plugging in data yields R (cm) = SQRT (46.9 (mw)/(1.0 (mW/cm 2 )*4*π) ) = 3.7 cm The RF Density equation shows that the minimum separation distance to be 3.7 cm. Since the EUT is considered by the manufacture to be a mobile unit, which by definition specifies that the antenna distance is greater than 20 cm, the manual therefore incorporates a caution statement that states that the unit should only be used when a separation of 20 cm is maintained between the antenna and users. This ensures compliance with the MPE requirements.

Technologies 3505 Francis Circle Alpharetta, GA 30004 (770) 740-0717 Dear Tim, This letter serves to confirm several of the operating parameters of the AX630 transmitter. The device is a spread spectrum transmitter that operates at a single frequency, namely 923.58 MHz. The device has an on-air data rate of 19.39 kb/s and utilizes ASK data modulation. The AX630 is a direct sequence spread spectrum transmitter that uses a BPSK spreading modulation with 63 spreading code ‘chips’ per data bit. A spread spectrum receiver that receives transmissions from the AX630 has FCC ID L2V0536ASR2. The theoretical process gain of the transmitter is defined by the spread occupied bandwidth (2*chipping frequency) divided by the narrowest filter in the receiver: 10 log (2.44MHz / 110kHz) = 13.46 dB Best regards, David Alley Axonn LLC
