CFS8DL6150RFSecurity Device Tranceiver

EXHIBIT 1 CFS8DL6150RF Functional Description. The 6150RF fixed transceiver is part of Ademco’s wireless 5800 alarm system. It is used in conjunction with portable transmitters (e.g. 5804) or portable transceivers (e.g. 5804BD). This allows remote control of the alarm system and provides remote indication that a control instruction has been enacted. These messages are transmitted at 345Mhz +/-82kHz using on- off keyed AM modulation. The 6150RF does not send a regular supervision or check-in message, it transmits no other messages except those which are a confirmation of reception of manually initiated control messages which have been received from portable remote control transmitters and control and alarm messages.

EXHIBIT 2 Circuit Description. CFS8DL6150RF The 6150RF is constructed on a single PCB. The PCB contains microcontrollers U2 and U9, LED indicators CR10 and CR11, sounder, keypad switches, RF transmitter Q3/Y2 etc., Low Noise Amplifier Q8, IF circuitry U5, Local Oscillator Y5 (refer to circuit schematic for component designations). The transmitter is a SAW resonator Colpitts oscillator, Q3, Y2 etc. The transmitter is on-off keyed (AM) modulated by a control signal from the microcontroller which turns PA Q4 on or off via Q6/Q7, thus modulating the output signal. The antenna ANT1/ANT2 is PCB mounted and is coupled to the transmitter output via cap C1. The receiver is a superhet with a single intermediate frequency at 10.7MHz. Q8 etc. is the low noise amplifier which is connected to the PCB mounted antennas. Diodes CR4/CR6 under the control of a microcontroller are periodically switched to provide system antenna diversity. The IC U5 includes a balanced mixer which converts the incoming signal down from 345MHz to 10.7MHz. This IC also includes the required IF gain and detected output. FL1 and FL2 are ceramic IF filters. IC U4 performs video filtering and processing and provides a data signal. The local oscillator (Y5) is a 355.7 Mhz SAW oscillator which has its active element contained within U5.

EXHIBIT 3 CFS8DL6150RF Message protocol, timing and duty cycle calculation. The data output is phase-encoded Manchester which has inherent 50% duty cycle. The transmitted data rate is 3.95 kBs +/-0.5%, i.e. each bit is 253.1uS duration typical and 254.3uS max. The word format consists of 72 bits, The duration of each word is 18.31mSec max. Each word is transmitted 6 times at each transmission event, the words are separated (start to start) by 120mSec. The total transmission time at each transmission event is 618.31mSec. The duty cycle over a 100mSec measuring period is calculated as follows: Duty Cycle = Actual RF transmission ON time / 100mSec (interval) Actual transmission ON time : 72 bits X 50% X 254.3uSec = 9.15mSec Therefore Duty cycle = 9.15 / 100 mSec = .0915 = 9.15% Summary. Max on-air time = 618.31mSec Duty cycle for average power calculation = 10%

EXHIBIT 5 CFS86150RF Report of Measurements. Measurements were made in accordance with the procedures and reporting requirements of ANSI C63.4-1992. The Test Set-Up (C63.4 section 10.1.3) is shown in the attached drawing. The attached photographs shows the attached power supply and telephony connections during the emissions measurements. The sequence of testing (C63.4 section 10.1.7) for radiated emissions is as follows: A preliminary scan was conducted with the receiver antenna close to the EUT in order to identify the emission characteristics of the EUT (C63.4 section 8.3.1.1). The antenna and EUT were then placed at the proper separation with the EUT positioned on a non-conducting turntable. The EUT was rotated on the turntable to maximize the received signal strength, then the receiver antenna height was varied to further maximize the received reading. Thereafter, the device was again rotated to a peak output position and the antenna height was re-adjusted for maximum received signal. This procedure was re-iterated until there was no further increase in signal level. This procedure was performed with the EUT rotating in three orthogonal planes (C63.4 section 13.1.4.1) to generate a final maximum reading which is recorded on the radiated emissions result sheet. Similar measurements were made on the receiver to ensure compliance as an unintentional radiator. See Exhibit 6 for list of test equipment (C63.4 section 10.1.4). Note, Spectrum Analyzer resolution bandwidths set as follows; (Video Bandwidth set greater than RBW) - For occupied bandwidth measurements, RBW = 100kHz, (This is in accordance with the minimum RBW allowed by C63.4, which requires RBW greater than 5% of the FCC required occupied bandwidth spec of 0.25% of center frequency). - For radiated emissions below 1 GHz, the RBW = 100kHz. Detector function set to peak. - For radiated emissions above 1 GHz, the RBW = 1MHz. Detector function set to peak. OCCUPIED BANDWIDTH is shown on attached plot. RADIATED EMISSIONS are recorded on attached sheet.
