EXHIBIT 1 CFS8DL5883 Functional Description. The 5883 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. In addition, alarm events initiated by the system are also transmitted to wireless relay and wireless siren devices. These messages are transmitted at 345Mhz +/-82kHz using on- off keyed AM modulation. The 5883 does not send a regular supervision or check-in message, it sends two different types of messages, described as follows: 1) a "short message" compliant with 15.231 a), this short message contains information for alarm messages and control messages initiated by the alarm system, and messages which are a confirmation of reception of manually initiated control messages which have been received from portable remote control transmitters. 2) a "long message" which contains alpha-numeric data, for transmission to a system keypad, compliant with 15.231 e). The long message and short message duty cycles and timings are described in detail in exhibit 3.

EXHIBIT 2 Circuit Description. CFS8DL5883 The 5883 is constructed on a single PCB. The PCB contains the RF transmitter and receiver circuitry as well as control circuitry, to coordinate transmission and reception of messaged with the alarm system. The transmitter is a SAW resonator Colpitts oscillator, Q14, Y6 etc. The transmitter is on-off keyed (AM) modulated by a control signal from the microcontroller U5 and U9 which turns PA Q18 on or off via Q11/Q12, thus modulating the output signal. The transmitter power output can also be set at two different power levels corresponding to the higher- power "control message" or the lower-power "data message" this is done by Q13, under the control of the U9 microcontroler. Note that microcontroler U9 also ensures that "data" messages are not transmitted more often than permitted by part 15.231.e. The RF output signal is connected to its two antenna via the output tuning and matching circuit L13,C67,R151,C64,C65 The receiver is a superhet with a single intermediate frequency at 10.7MHz. Q3 etc. is the low noise amplifier which is connected to the PCB mounted antennas. Diodes CR7/CR8 under the control of the microcontroller U5 are periodically switched to provide system antenna diversity. The IC U1 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 is a ceramic IF filter. IC U2 etc., perform video filtering and processing and provides a data signal. The local oscillator (Y3/Q5) is a 59.28333 Mhz Xtal oscillator which outputs 355.7MHz to the mixer via multiplier L6/C24/C25.

EXHIBIT 3CFS8DL5883 Message protocol, timing and duty cycle calculation. SHORT MESSAGE PER 15.231 a) The data output is phase encoded Manchester which has inherent 50% duty cycle. The transmitted data rate is 3.676 kBs +/-0.05%, i.e. each bit is 272uS duration typical and 272.13uS max. The worst case data format consists of 120 bits, The duration of each word is 32.655 mSec max. Each word is transmitted 5 times at each transmission event, the words are separated (start to start) by 105mSec max.. Total max transmission time at each transmission = 452.655mSec. The duty cycle over a 100mSec measuring period is as follows: Duty Cycle = Actual RF transmission ON time / 100mSec (interval) Actual transmission ON time = 120 bits X 50% X 272.13uSec = = 16.33mSec Therefore Duty cycle = 16.33 / 100 mSec = .1633 =16.33% LONG MESSAGE PER 15.231 e) The data output is phase encoded Manchester which has inherent 50% duty cycle. The transmitted data rate is 10kBs +/-0.05%, i.e. each bit is 100uS duration typical and 100.05uS max. The worst case data format consists of 440 bits, The duration of each word is 44.02 mSec max. Each word is transmitted 5 times at each transmission event, the words are separated (start to start) by 105mSec. Total max transmission time at each transmission = 464.02mSec. The transmitter is inhibited from further transmission of the long message for 15 seconds after each transmission (i.e. >30 times the transmission duration per 15.231 e)). 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 = 440 bits X 50% X 100.05uSec = = 22.011mSec Therefore Duty cycle = 22.011 / 100 mSec = .22011 = 22.01%
