Operational Description

EXHIBIT 1-1 CFS8DL5800STAT Functional Description. The 5800STAT is a battery powered portable transmitter and is part of a wireless control system which complies with 15.231(e). It is used in conjunction with a receiver to control a residential heating, ventilation and air conditioning system. The transmitter does NOT send actual temperature data, it simply sends a control message to the receiver when the temperature reaches a certain internally preset temperature The messages are transmitted at 345Mhz +/-82Khz using on-off keyed AM modulation. The 5800STAT sends a regular supervision "or check-in" message, no more often than once every 7.5 minutes. It also sends control messages initiated by manual override switches on the thermostat and at preset operating set points.

Operational Description

EXHIBIT 3 CFS8DL5800STAT 5800STAT - Duty Cycle Calculation Message protocol, timing and duty cycle calculation. The data output is phase-encoded Manchester that has inherent 50% duty cycle and consists of 64 bits per word A supervision transmission is six identical words separated by (start to start) by nominal 125mSec (100 mSec min, 150 mSec max). Each message has a nominal data rate of 3.7 kb/s (3.2kb/s min to 4.2kb/s max). Therefore the duty cycle is calculation is as follows: The word format consists of 64 bits, The duration of each bit is 312.5 uSec max. The duty cycle over a 100 mSec measuring period is calculated as follows: Duty cycle = Actual RF transmission ON time / 100 mSec Actual transmission ON time = 64 bits X 50% X 312.5 uSec = 10 mSec Therefore duty cycle = 10 / 100 mSec = .10 = 10%, and peak to average field strength is 20 db. Total on-air time for a supervision transmission is: 64 X 312.5 uSec + (5 X 150 mSec) = 0.77 seconds In the case of an alarm transmission, the group of six transmissions is repeated twice, with the second group delayed from the first by a max time of 2 seconds. The worst case on-air time is 2 X (supervision time) + 2 = 3.54 seconds Summary: - Duty cycle = 10% On airtime = 3.54 seconds

Operational Description

EXHIBIT 2-1 CFS8DL5800STAT Operational Description The 5800STAT uses a single chip transmitter which contains a: reference oscillator, a divide by 32 divider, phase detector, and carrier oscillator, these all combine to form a phase locked loop .the carrier oscillator is fed into the PA stage, which is also part of the chip.There are a minimum of external components used. C2 is the bypassing for the chip,.crystal Y1 is the frequency determining element of the reference oscillator ( 10.78125 Mhz. X 32 = 345.00 Mhz. ). C6 and L2 tune the PA, while C11 bypasses the tank circuit. L1 and C14 serve to further reduce harmonics, while C3 couples energy into the printed antenna. the network R1, R3 / C1, shapes the input data. The TX gate and Data come from the standard ADEMCO encoder chip. It should be reiterated, that the 5800STAT only sends COMANDS to run a heating, cooling system, or fan and NOT the actual temperature data itself.

Test Report

EXHIBIT 5-1 CFS8DL5800STAT Report of Measurements. Measurements were made at Ademco 's Measurement Facility at 160 Eileen Way , Syosset , NY 11791 , FCC Registration number : 90421. 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 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.
