The circuit closes again when the vibra-tion stops. The sensor microcontroller “sees” the open/close action as a pulse, causing the sensor to transmit an alarm signal. The sensor has two different detection modes:•Gross Attack - detect a violent blow sufficient in length to trip sensor.•Pulse Count - detect a sufficient number of less violent blows (rapping or tapping).The sensor includes an internal magnetic reed switch that must be disabled if it is not used.Extend the battery life of the sensor by adding a second 3-volt lithium battery.Installation Guidelines•Learn the sensor before adjusting the shock sensitivity. The sensor is shipped with the reed switch enabled and open, and this is how it must be learned.•Before permanently mounting the sensor, test it at the intended location to make sure that the panel can receive sensor signal transmissions. The sensor is an RF device and there may be blind or non-operational locations within the installation. Normally, these can be overcome by moving the sensor or receiver. •Always mount the shock sensor so that the detector is on the frame and not on the glass. See Figure 2 for mount-ing locations.•Mount the sensor in a location where the structure can transmit vibrations to the sensor.•The sensor can be mounted on a vertical surface or on a horizontal (flat) surface.•Make sure the window fits snugly in the frame and doesn’t move or rattle.•Hold the sensor against the frame to make sure the sen-sor base fits on the surface area of the frame and doesn’t extend over the surface edges.Figure 1.

2PRELIMINARY 10/1/03InstallationCaution!You must be free of all static electricity when handling elec-tronic components. Touch a grounded, bare metal surface before touching a circuit board or wear a grounded wrist strap.1. Insert a slotted screwdriver into the slot at the top end of the unit and remove the cover by lifting it up (see Figure 2).Figure 2. Removing the Cover2. Using the flathead mounting screws, secure the base to the mounting surface either vertically or horizontally as required (see Figure 3).Figure 3. Sensor Mounting Holes3. Position the shock element and press it firmly into its socket.NoteOn a vertical surface, the shock sensor element must always be oriented with its screw terminals down, or the writing on the shock element horizontal.Figure 4. Positioning the Shock Element According to Mounting Orientation on a Vertical SurfaceNoteOn a horizontal surface (sill or ledge), any orientation is allowed, but certain sensor element orientations are better than others. The element is much better at detecting hori-zontal vibrations perpendicular to its writing than it is parallel vibrations (see Figure 5).Figure 5. Positioning Shock Elements for Horizontal Sur-face Mounting4. If using the reed switch, use the two remaining screws to mount the magnet so its arrow is aligned with the arrow on the sensor case (see Figure 7).Figure 6. Possible Magnet/Reed Switch AlignmentImportant!You must disable the reed switch using the dip switches on the circuit board if you are not using it. If the reed switch is enabled but no magnet is installed, the sensor will be in a continuous alarm state. See the Sensor Settings section for more information.5. Install the tamper switch as shown (see Figure 7).Figure 7. Installing the Tamper Switch6. Install the 4.7 k Ohm EOL resistor across the terminals of the external switch block.1 2 3 4 ONMounting HoleMounting Hole(Wall Tamper)1 2 3 4 ON1 2 3 4 ONShock ElementScrew TerminalsScrew Terminals1 2 3 4 ON1 2 3 4 ONPerpendicularCORRECTINCORRECTDirection ofVibration1 2 3 4 ONMagnetAlignmentMarksReed Switch12
3PRELIMINARY 10/1/03Setting the Detection ModeThe shock sensor has two detection modes:•Gross Attack - detects a violent blow sufficient in length to trip sensor.•Pulse Count - detects a sufficient number of less violent blows (rapping or tapping). Pulse Count signals are counted at 1-second intervals and stored in a 30-second digital memory. These small signals can detect an intruder gently prying open a win-dow or door frame.To set the shock sensor detection modes:1. Hold in the tamper spring. Continue to hold in while mov-ing the DIP switches to their desired settings.2. Set the DIP switches to the desired pulse count (see Table 1). The LED will start blinking once a DIP switch is moved.3. Set the DIP Switches to the desired Gross Attack sensi-tivity (See Table 2).4. Release the tamper spring. The LED will flash quickly 3 times to indicate the settings have been programmed.5. Repeat steps 1-4 each time you make a sensitivity change. It may then be necessary to reset the DIP switches to their proper device settings (See Sensor Set-tings).Testing the Detection ModesTo test the Pulse Count setting:•Generate small shocks on the mounting structure. Each time a shock is detected, a pulse is registered in memory and the LED will blink for one second. If the programmed pulse count is reached within the most recent 30 sec-onds, the alarm will trip and the LED will light for approx-imately 4 seconds. If the alarm trips for any reason, the stored pulses are cancelled.To test the Gross Attack setting:•Apply high level shocks to the mounting structure, using the LED as a guide to when the alarm trips (LED on for 4 seconds). The LED will blink for 1 second every time the sensor detects a pulse. A shock that is severe enough to cause an alarm will cause the LED to light for approximately 4 seconds.Sensor SettingsAfter programming the Detection Mode, the DIP switches are used to set up the sensors use of the reed switches and/or external contacts. If the external contact is not used the 4.7 k Ohm EOL resistor must be installed across the ter-minals of the external switch block.With the tamper spring in the up position, set the DIP switches to the desired settings (See Table 3).Important!DO NOT remove the reed switches from the circuit board! The Shock Sensor will not function properly. If you don’t need to use the reed switches, disable them with the DIP switches as described in Table 3.System ProgrammingThis section describes the basic steps for adding the sensor to panel memory. Refer to the specific panel installation instructions for complete programming details.The reed switch must be enabled and open when learning the sensor.1. With the cover on the sensor, set the panel to Program mode.2. Proceed to the LEARN SENSORS menu.3. Select the appropriate sensor group and sensor number assignments.4. When prompted by the panel to trip the sensor, remove the sensor cover to activate the tamper switch.5. Exit program mode.RF TestingThis section describes the basic steps for testing the sen-sor. Refer to the specific panel or receiver installation instructions for complete testing details.1. Set the panel to Sensor Test.2. Trip the sensor.3. Listen for appropriate response from system sirens.4. Exit Sensor Test.•Use an RF Sniffer to help diagnose sensor problems.Table 1: Pulse Count AdjustmentDIP Switch 1 DIP Switch 2 30-second Pulse CountOFF OFF 4ON OFF 6OFF ON 8ON ON DisabledTable 2: Gross Attack Sensitivity SettingsDIP Switch 3 DIP Switch 4 SensitivityOFF OFF 1 (most sensitive)ON OFF 2OFF ON 3ON ON 4 (least sensitive)Table 3: Sensor SettingsSwitch Number OFF ON1 Unused Unused2 Disable Reed SwitchesEnable Reed Switches3 Disable External ContactEnable External Contact4 External Contact is Normally OpenExternal Contact is Normally Closed
4PRELIMINARY 10/1/03Battery ReplacementWhen the system indicates that the sensor has a low bat-tery, remove the old battery and install a new battery (Dura-cell DL123A or a Sanyo CR123A) into the battery holder, observing proper polarity.Caution!Replace only with a Duracell DL123A battery or a Sanyo CR123A battery. Observe polarity when installing a new battery.
