DRAFT – 24 February 2004 K9674ax 2/04 Rev. A $'(0&2 :LUHOHVV'LDOHU  Installation and Setup Guide GENERAL INFORMATION The 5842 Wireless Dialer is a combination Central Station dialer and RF transceiver. It receives and acknowledges RF messages from the control’s transceiver. In response, it sends reports to the central station via the dialer. The 5842 also sends acknowledgements, supervisory and tamper RF transmissions to the control. DIALER FEATURES • ADEMCO Contact ID® central station reporting format. • Reports low battery conditions to control panel. • Front cover tamper switch. The LEDs and their functions are described below: LED Function Green Lights continuously and flickers during RF activity. Yellow Flashes once each time the 5842 sends an acknowledge message to the control. Stays on while the dialer is using the telephone line. Red Lights to indicate no setup information has been received, or setup information is incomplete. Once setup information is received the LED will go off. REDYELGRN MOUNTING HOLES (4) ANTENNAS (INSERT IN RIGHT-HAND TERMINALS) BREAKOUT WIRING OPENING TAMPER SWITCH RJ31X TELEPHONE JACK WIRING OPENING 5842-001-V0 TELEPHONE IN TELEPHONE OUT RJ11 TELEPHONE JACK BATTERY BATTERY Figure 1 - 5842 Wireless Dialer (cover removed) OPERATION The 5842 dialer is triggered by an RF message that contains a command, (i.e. a dialer report message or a line seize and clear command). It processes the command and remains active for a short time after it has received and acknowledged the last RF message from the control panel. The 5842 then reverts to Low current standby mode. The Wireless Dialer is normally in a low current standby mode, which maximizes battery life. At specific intervals the unit’s RF receiver is switched on, and listens for a “Time Sync” message from the control panel. If the “Time Sync” message is not received within a specified time the 5842 switches to an active receiving state. If the 5842 still does not receive a message it transmits a time sync fault to the control panel. Normal operation resumes after the control panel logs the event and transmits a “Time Sync Fault Restore” message. Failure to receive a kiss-off signal from the central station is reported to the control panel. Dialer reports are sent to the central station using ADEMCO Contact ID® format only. PROGRAMMING AND INSTALLING THE 5842 WIRELESS DIALER Refer to the following procedure and the Installation and Setup Guide for the Control Panel being installed to program and install the 5842 Wireless Dialer: -2- If the 5842 batteries are removed refer to REPLACING THE BATTERIES section before reinstalling/replacing the cells. Use only 1.5-volt alkaline batteries. Observe the polarity when installing batteries. STEP DESCRIPTION 1. Remove the cover from the 5842 Wireless Dialer. Note: The 5842 is configured to accept programming data any time the cover is removed from the unit. The unit performs this function whether or not it has been previously programmed. 2. Place the control in the Programming Mode and enable operation with the 5842 Wireless Dialer. Refer to the procedure in the Installation and Setup Guide for the Control Panel that is being installed. 3. Install each antenna in the respective right-hand terminal of the two terminal blocks at the upper edge of the 5842’s circuit board, and tighten the screws to secure them. (Refer to Figure 1.) 4. Install two 1.5V AA batteries in the 5842. The 5842 will activate its receiver and begin listening for an RF broadcast from the control panel. The panel’s Green, Yellow and Red LEDs will come on for one- (1) second after the unit is powered-up. Notes: (1) Do not mount the 5842 or install the cover at this time. (2) To conserve battery life, the 5842’s listen mode has a five (5) minute time-out. If the 5842 times out, install and remove the cover to restart the listen mode. 5. Exit the control panel’s programming mode by entering ✻ 99. 6. The control panel will transmit the setup information and the 5842’s Green and Yellow LEDs will flash briefly. 7. The control panel will indicate receipt of the RF acknowledgement from the 5842 by beeping three times and the 5842’s red LED will go out. 8. Install the cover on the 5842. 9. Place the control panel in Go/No Go Test Mode. 10. After selecting a mounting location for the 5842 remove and replace the cover to activate the tamper and ensure the control has received the transmission. 11. Exit the controls Go/No Go Test Mode (Refer to the Installation Instructions for the Control Panel being installed) and cause the control to send several dialer reports via the 5842. Ensure that the central station receives each report. 12. For concealed wiring, route wires through the rectangular opening at the rear of the base before mounting. For surface wiring entry, a thin breakaway area is provided along the base's right edge. 13. Mount the case back to a wall or to and electrical box using the 25mm-long self-tapping screws that are supplied (mollies for drywall are not supplied). 14. Make Phone Line Connections - For local or full line seizure proceed to the appropriate steps below and refer to figure 2. Local Seizure: Only the telephone equipment connected to the 5842 Wireless Dialer’s RJ11 jack will be disconnected to prevent interference while the 5842 is using the phone line. This may or may not include ALL the telephone equipment on the premises. a. Connect the incoming phone line to the 5842’s internal RJ31 jack. b. Connect the handset phone lines to either 5842’s internal RJ11 jack. Full Line Seizure : Requires the installation of an RJ31X jack at the network demarcation (before any other premises connections). It ensures that the ALL premises telephone equipment is disconnected and will not interfere with the 5842 while it is using the phone line. In the event of a problem with the 5842 it will also ensure uninterrupted service to all premises telephone equipment when the cable to the 5842 has been d…

Operational Description

EXHIBIT 2-1 CFS8DL5842 CIRCUIT DESCRIPTION ANT1 & ANT2 provide diversity operation for both transmitter and receiver. They are switched by CR1, CR4, Q3, Q22 etc., all under control of the microprocessor (U5). Transmit and receive signals are multiplexed by C3, L5, FL1,L6, & C6, so no TR switch is needed. The receiver consists of a single chip receiver (U1) with a internal PLL'ed LO who's FDE is YL3 (20.89375 X 16 = 334.30 MHz. for low side injection. ). FL2 (10.7 MHz) gives IF selectivity, and op-amp (U4) etc., processes the base-band information before passing it to the microprocessor (U5) The transmitter is a single chip, PLL'ed (U2), etc., whose FDE is YL5 (10.78125 X 32 = 345 MHz.) operation is under control of the microprocessor (U5).

Operational Description

EXHIBIT 3-1 CFS8DL5842 5842 - 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 120 bits per message. One group of messages is five identical messages separated by (start to start) by nominal 130mSec. Each message has a nominal data rate of 4.0 kb/s Therefore the duty cycle calculation is as follows: The message format consists of 120 bits, The duration of each bit is 250.0 uSec max. The duty cycle over a 100 mSec 'OFF time' is calculated as follows: Duty cycle = Actual RF transmission ON time / 100 mSec Actual transmission 'ON' time = 120 bits X 50% X 250.0 uSec = 15 mSec Therefore duty cycle = 15 mSec / 100 mSec = .15 = 15%, and peak to average field strength is 20 db. Total on-air time for ONE GROUP is: (120 X 250.0 uSec) X 5 + (4 X 100 mSec) = 0.550 seconds Total on-air time for 'TWO GROUPS' is: The group of five transmissions is repeated twice, second group delayed from the first group by a max. time of 1 second. The worst case on-air time is 2 X 0.550 + 1 = 2.10 seconds The worst case Duty cycle is : 15%

Test Report

EXHIBIT 5-1 CFS8DL5842 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.
