ElmoTech Ltd Version 1.0 THE OFFENDER’S PREMISES Monitoring System Location In order to install the Monitoring System, you will need to find the best location for the DCU unit. The ideal place for the DCU unit is in the center of the house, 3 feet off the ground and at least 1 foot away from the wall. Figure 1 Ideal DCU Location DCU & Transmitter Field Installation Manual 9
Version 1.0 ElmoTech Ltd DCU & Transmitter Field Installation Manual 10The DCU unit should be in an open area away from other electrical appliances (e.g. personal computers, laptops) or any metal objects. Installing the DCU Unit In order to install the DCU unit: 1. Plug the appropriate end of the power adapter cord into the 12VDC socket at the back of the DCU unit. 2. Plug the power adapter into a wall power socket. The DCU unit makes an audible beeping sound and then runs through a series of built-in-tests to check that everything is in order. 3. After completing the tests successfully the DCU unit beeps again and the two external LED’s, located at the rear of the DCU unit, are turned on. This indicates that the DCU unit is in working order. The LED indicators are: • Left LED - indicates that power is connected • Right LED - indicates that the DCU unit has registered to a telephone network (network registration may take up to one minute after built-in-test completion).
ElmoTech Ltd Version 1.0 DCU & Transmitter Field Installation Manual 11 Figure 2 Diagrammatic View of a DCU If, at the end of the start-up self test, audible beeping sounds are heard and all three LED’s flash for 10 seconds, it indicates one of the following possible failures: i Case open micro-switch malfunction. i Tilt sensor malfunction. i Range threshold values lost (maximum reception range is used in this case).
Version 1.0 ElmoTech Ltd DCU & Transmitter Field Installation Manual 12Downloading the Curfew Schedule Downloading Curfew Schedule data requires that the CMS (Central Monitoring System) telephones the Offender’s premises and transmits a series of signals to the DCU unit to allow it to monitor the Offender. After the DCU unit has been installed, perform the following: 1. Verify that the DCU units right LED is not flashing (i.e. the line is not busy). 2. Call the Monitoring Center personnel, using a mobile phone, and ask them to perform a download. 3. Monitor the following download communication process directly from the DCU unit at the offender’s premises: • The telephone line LED (right) on the DCU unit flashes. The flashing indicates that the DCU unit has made a call, to the central computer. The telephone line LED then returns to its steady state. • After a short while the telephone line LED starts flashing for a second time. This indicates the DCU unit has made another call to the central computer. The telephone line LED then stops flashing. • After another short wait the telephone line LED starts flashing for the third time. This indicates that the DCU unit has made its last call to the central computer. When the telephone line LED stops flashing, the DCU unit has received all the information it requires and the monitoring process begins.
ElmoTech Ltd Version 1.0 4. The Monitor Center personnel call back (optional) to confirm a successful download or to inform that the download failed and has to be performed again. If the download is successful, the following information is downloaded: • Transmitter code • The curfew schedule • Schedule flexibility • Left violation sensitivity • Sanity calls intervals If there are other Transmitters in the same area (for example, if the installation was done, in an office, where other offenders may be present), the DCU unit may receive a transmission from a source other than the intended Transmitter. The download, in this case, is rejected and another download will need to be initiated. Only when the DCU unit receives three successful downloads from the correct Transmitter (the one attached to the Offender), it continues to monitor that specific Transmitter only. DCU & Transmitter Field Installation Manual 13
Version 1.0 ElmoTech Ltd DCU & Transmitter Field Installation Manual 14Installing the Transmitter The officer should bring the following equipment for a Transmitter installation: • Transmitter • Male and female strap Clips • Electronic key • Strap holder • Locking tool • Flat-head screwdriver Calibrating the Transmitter Before any installation, the Transmitter has to be turned-on and calibrated. After the DCU unit is connected and in monitoring mode, do the following: 1. Stand close to the DCU unit in order to hear the audible confirmation of the Transmitter calibration. 2. Hold the transmitter in your hand with the 4 metal pins (2 pairs, along the strap) pointing forward. 3. Hold the Electronic Key in your other hand, with the black button pointing toward the open or free end of the strap.
ElmoTech Ltd Version 1.0 Figure 3 Calibrating the Transmitter 4. Press the Electronic Key down over one pair of metal pins (it does not matter which) with the two touch points on the Electronic Key matching the pair of metal pins on the Transmitter strap. Hold the Electronic key in this position while you do the next step. 5. Press the red button on the Electronic Key down for one second; the red light turns steadily on for two (2) seconds. 6. If the transmitter successfully receives the reset command, the red light, on the Electronic Key, will flash for two (2) seconds. If the transmitter failed to receive the calibration command, the red light will turn off after the initial two (2) seconds on. If the Electronic Key battery is low the red light will immediately flash for two (2) seconds, once the red button is pressed. (No command is sent to the Transmitter). DCU & Transmitter Field Installation Manual 15
Version 1.0 ElmoTech Ltd 7. Place the Transmitter on its side on a non-metal table and wait 30 to 60 seconds, until audible beeping sounds are heard from the DCU unit. These beeps indicate that the Transmitter has successfully completed its Calibration process and is ready to be mounted on the offender. If a number of Transmitters calibrated at the same time, it is important to wait for the final beeps to be sure that the calibration went OK. After the OK confirmation the next Transmitter can be calibrated. Attaching the Transmitter In order to attach the Transmitter to the Offender, do the following: 1. Flip a strap holder over the short strap of the Transmitter. 2. Attach the female Clip to the underside of the Transmitter’s short strap (to lie against the Offenders skin). Verify that the closed end of the clip fits with the edge of the strap. Make sure the silver line is visible. DCU & Transmitter Field Installation Manual 16
ElmoTech Ltd Version 1.0 Female clip SilverlineFigure 4 Attaching the Transmitter 3. Wrap the Transmitter around the offender’s ankle at its narrowest point. Ensure that the protruding side of the Transmitter is directed upwards. Figure 5 Protruding side of Transmitter directed upwards DCU & Transmitter Field Installation Manual 17
Version 1.0 ElmoTech Ltd DCU & Transmitter Field Installation Manual 18 It is important that the Transmitter fits tight around the offender’s ankle, but isn’t squeezing. Since it is permissible to wear a sock underneath the Transmitter, try to mount the Transmitter over the sock before it is fastened. 4. Cover the female Clip with the male Clip ensuring that the four pins on the male Clip fit correctly into the female Clip (the markings on the side of each clip have to match). Male & Female clips attached Figure 6 Male\Female Clips Attached 5. Ask the Offender to stand up and move around to insure that the Transmitter is comfortable. 6. Fasten the two Clips with the locking tool. Be sure to fasten all the four pins well. An audible clicking sound should be heard, indicating that the Clips are closed properly. Don’t install the Transmitter over a thick sock, since the transmitter will get too loose once the sock is removed. If the Transmitter is installed without a sock, instruct the offender that he should not put on a very thick sock, and then try to pull it under the transmitter.
ElmoTech Ltd Version 1.0 DCU & Transmitter Field Installation Manual 19 The Offender may wear a thin sock underneath and a thick sock over the Transmitter. DCU Range Setting DCU Range Setting is designed in order to create a limited free movement area. This ensures that Offender stays as close as possible to his\her premises and the immediate surrounding area. Four range settings are available: Short, Medium, Long and Maximum. To change the DCU range, a central computer command is required. In order to set and test the DCU reception range, do the following: 1. Estimate the offender premises size and decide on the appropriate range setting for starting the range test. 2. Phone the Monitor Center/Agency personnel and ask them, first, to select the appropriate range and then to initiate the range setting test. Once the range setting test has been initiated by the Monitor Center, the following occurs: • The Offender’s telephone rings approximately 2-3 times. • After the phone stops ringing, the telephone line LED (right) on the DCU unit flashes for a while and then returns to its steady state. • After the telephone line LED on the DCU unit stops flashing, the middle LED blinks 3 times in quick
Version 1.0 ElmoTech Ltd sequence accompanied by 3 audible beeping sounds. This means that range test has started. The DCU unit will be in the range test mode for approximately 15 minutes, unless the Monitor Center/Agency terminates it manually. You can now escort the Offender around his/her premises in order to check that the range is sufficient, and to check for dead spots. 3. Escort the offender to the following locations in his/her premises: • Locations that are the most distant from the DCU unit. • Locations behind large metal objects. • Locations where the Offender spends long periods of time (e.g. bedroom, toilet, living room, etc.). • Remote locations where the Offender is allowed to stay while at home (e.g. garage, cellar, yard, etc.). • Any location that your experience and common sense suggests to be a viable location must be tested. Don’t perform a range test in any locations where you don’t want the Offender to be (e.g. yard, garage, etc.). 4. An assistant stands next to the DCU unit and observes the middle LED. Every time the DCU unit receives a transmission from the PID (approximately every 20 seconds) the middle LED flashes 3 times in quick sequence. DCU & Transmitter Field Installation Manual 20
ElmoTech Ltd Version 1.0 5. Wait for up to two minutes in each checked location. During these two minutes four transmissions should be received from the PID. If four transmissions are received before two minutes have elapsed, you can move with the Offender to the next location to be checked. If less than four transmissions are received, phone the Monitor Center/ Agency and ask to change the range setting to a longer range. If the range setting is already set at long range, relocate the DCU unit in order to get better coverage. 6. After satisfactory testing of all relevant locations, ask the Monitor Center/Agency personnel to end the range test (manually). If the range is not sufficient, you have to ask the Monitor Center/Agency to perform a new ‘Start Range’ with a longer range and then re-test where the previous test failed. 7. Upon ending the range test, the DCU unit makes an audible beeping sound to indicate range test completion. As a precaution against accidentally leaving the DCU unit in the range-testing mode, the DCU unit automatically terminates the range test 15 minutes after initiation. Therefore, if the range test lasts longer than 15 minutes, you will have to request the Monitor Center / Agency to re-activate it. DCU & Transmitter Field Installation Manual 21

ElmoTech Ltd Version 1.0 DCU & Transmitter Field Installation Manual 23 DAILY OPERATING INSTRUCTIONS In general, the installed DCU is transparent to the user of the telephone. All incoming calls trigger a pre—defined number of rings (system default is set at 6 rings) through out the house before the DCU picks up the call. Incoming Calls The central computer may, from time to time, initiate a call to the DCU. Therefore, the Offender may receive two types of phone calls; regular calls from other people, and occasional calls from the central computer. Accepting an incoming call The phone will ring up to 6 times, during which the call may be answered. After 6 rings, the DCU unit will answer and disconnect the call. If the Offender hears a light sound on the line during the first few seconds of the conversation, he/she should not be alarmed. The DCU automatically interacts with each incoming call for the first few seconds. During the conversation the Offender might hear a short tune from the DCU. This tune indicates that the DCU needs to call the central computer. In this case, the Offender should complete his/her conversation as soon as possible to enable the DCU to make its call.
Version 1.0 ElmoTech Ltd DCU & Transmitter Field Installation Manual 24 Note that it is imperative that the Offender gives up the line when the DCU needs to call. Failure to do so will be detected and could result in a violation situation. Outgoing Calls The DCU calls the Monitor Center, either to report a violation or to report its current status. Performing an outgoing call If the Offender tries to perform an outgoing call and hears a sharp modem sound, the Offender must hang up the phone immediately. This means that the central computer is trying to call the DCU. Note that the Offender should not attempt to use the phone during the next 8 minutes. During the conversation the Offender might hear a short tune from the DCU. This tune indicates that the DCU needs to call the central computer. In this case, the Offender should complete his/her conversation as soon as possible to enable the DCU to make its call. Note that it is imperative that the Offender gives up the line when the DCU needs to call. Failure to do so will be detected and could result in a violation situation.
