Operational Description

EXHIBIT 1 CFS8DL5817CB-1 Functional Description. The 5817CB-1 is a battery powered portable transmitter and is part of a wireless alarm system. It is used in conjunction with a receiver (5881) to indicate an open door or window to the alarm system. It is functionaly identical to the 5817CB. The messages are transmitted at 345Mhz +/-82Khz using on-off keyed AM modulation. The 5817CB-1 sends a regular supervision or check-in message, no more often than once per hour. It also sends messages initiated by the condition of the loop (open or closed).

Operational Description

EXHIBIT 2-1 CFS8DL5817CB-1 The 5817CB-1 remote zone transmitter consists of a message encoding chip (U1) , a SAW - stabilized Colpits oscillator (Q2) , and PA stage (Q3). The message encoding chip is responsible for: 1. generating the zone alarm message 2. generating the tamper and supervision messages. 3. performing all watchdog functions. When sending a message, the message encoder chip turns on the SAW oscillator (Q2) using Q1 to apply VCC , R7 and R8 bias Q2 on, SAW device Y1 sets the frequency, capacitors C10 and C11 set the feedback , R9 sets the current through the oscillator, and C13 couples the RF into the PA. The encoder chip then uses transistors Q4 - 5 to key the PA (Q3). This is on / off AM modulation (FCC Type 100KK1 modulation )C19 and L1 tune the PA, C15, RL27, suppress harmonics, and C17 / C18 tune the antenna to resonance.

Operational Description

EXHIBIT 3-1 CFS8DL5817CB-1 5817CB-1 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 3-2 TIMING DIAGRAM CFS8DL5817CB-1 Section 15.255(b) Section 15.255(b), when the radiated emission limits are expressed in terms of the average value of the emission, and pulsed operation is employed, the measurement field strength shall be determined by averaging over one complete pulse train, including blanking intervals, as long as the pulse train does not exceed 0.1 seconds. The exact method of calculating the average field strength shall be submitted with any application for certification. SEE THE NEXT PAGE

Test Report

EXHIBIT 5-1 CFS8DL5817CB-1 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.
