B4Z-840B-SHKShock Sensor

1 D†‡hyyh‡v‚ D†‡…ˆp‡v‚† B@D‡r…y‚tv‘ 9 PRELIMINARY 10/1/03 Product Summary The Learn Mode Shock Sensor has the following three main functions: •To detect the vibrations made by an intruder trying to break a window or door. •To detect a window or door opening. •To detect tamper situations, such as an intruder remov- ing the sensor cover or the sensor from the wall. Vibrations cause a momentary open circuit in the shock ele- ment of the sensor. 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.

A September 2003 2 PRELIMINARY 10/1/03 Installation Caution! 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 Cover 2. 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 Holes 3. Position the shock element and press it firmly into its socket. Note On 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 Surface Note On 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 Mounting 4. 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 Alignment Important! 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 Switch 6. Install the 4.7 k Ohm EOL resistor across the terminals of the external switch block. 1 2 3 4 ON Mounting Hole Mounting Hole (Wall Tamper) 1 2 3 4 ON 1 2 3 4 ON Shock Element Screw Terminals Screw Terminals 1 2 3 4 ON 1 2 3 4 ON Perpendicular CORRECT INCORRECT Direction of Vibration 1 2 3 4 ON Magnet Alignment Marks Reed Switch 1 2 3 PRELIMINARY 10/1/03 Setting the Detection Mode The 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 Modes To 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- o…

1/27/2004 FCC ID: B4Z-840B-SHK Product Description The product is a wireless shock sensor (detector) used in conjunction with a wireless security alarm system. The shock sensor unit monitors the environment for the presence of shock, or sudden vibrations. If any of these conditions are found, the unit goes into alarm. In alarm the unit will transmit an alarm message to the security alarm panel. The panel will then sound its sirens, and call the monitoring station for help. Normally the unit only transmits supervisory signals every hour. This product is the combination of a shock sensor manufactured Sentrol, a division of SLC Technologies, and the transmitter manufactured by ITI. ITI has code imbedded in the microcontroller of the shock sensor to control the transmitter. EXHIBIT I Operational Description

Lab Measurements Discussion / Test Notes 3.1 Test Notes 3.1.1 Transmissions shall cease within 5 seconds of activation [ §15.231(a)(2) ] When the sensor communicates with the security alarm panel, 1 packet IS sent in a transmission. The packet duration is, at most, 30 mS, see Duty Cycle Correction Factor [§15.231(b)(2) and §15.35(c)] . The following plot shows a packet transmission that concludes in less than 5 seconds.
