II. Introduction The LCT-XX Sensor Transmitter is a sophisticated processor and transmitter housed in a compact rugged case which facilitates storage, transportation, and concealment. This unit is ideal for long term deployment from 3 months to one year or longer depending on configuration. Constructed of injection-molded plastic, the watertight and corrosion-proof case may either be deployed above ground or buried for security and stealth. Only the antenna needs to be above ground for proper operation. A single LCT-XX unit receives, processes, and transmits information generated by contact closure/open, seismic (SPS-21), passive infrared (PIR), or dual-axis magnetometer (MS-10) probes either individually or in various combinations of deployment, giving the system maximum flexibility. A classify/detect switch combined with PORT SELECT switches control how the inputs are processed. Four standard models are available with the following designations and inputs: LCT-DS 1 Directional + 1 Seismic + 1 Pair N.O. Contacts LCT-DD 2 Directional LCT-SS 2 Seismic + 1 Pair N.O. Contacts LCT-CC 3 Pairs N.O. Contacts + 3 Pairs N.C. Contacts The LCT-XX was optimized to operate on two 6 VDC lantern batteries and can transmit over 90,000 alarms before battery replacement is required. Other power supply options are available and include rechargeable batteries as well as an external power input for sources such as an external battery, solar-panel, or other 12 VDC supply. Proper selection of these options depends on environmental conditions and the length of time the unit is to be deployed. For further information, contact Monitron, Inc. Alarm Format When an intrusion is detected and classified, an alarm is encoded using the following format: XXXX-P, where: XXXX = unit’s address, P = alarm Port number generated by the processor. When the LCT-XX generates a self test alarm, or a test alarm is manually sent, P is the unit’s programmed port number. The letter “B” is added to the end of the alarm message when the batteries need to be replaced. NOTE: Although Monitron equipment is 100% backwards compatible with earlier Sparton sensor products still in use, Sparton repeaters and monitors are limited to addresses in the range of 0000 through 1999.

III. Connections & Controls Input connectors and the standard BNC jack for the antenna are located on the lid of the LCT-XX. Note that input J1 is closer to the handle and J2 is closer to the hinge. Control functions for channel select, alarm repeat, self-test time, and address are set using decimal format rotary switches, which are clearly labeled and easily read. Each sensor input has user selectable individual sensitivity gain setting and alarm number (Port). A slide switch controls operation in either classify or detect mode.

IV. Antenna Preparation Using the Allen wrench included with the antenna, loosen the set screw in the side of the BNC connector and remove the whip. Refer to the Rod Cutting Chart included with the antenna and cut the whip to the length appropriate for the frequency the LCT-XX will be transmitting on. Insert the whip into the connector and tighten the set screw. V. Battery Installation The LCT-XX has been impedance matched for use with two Duracell ProCell 6 volt lantern batteries (PC915). The use of inferior batteries may significantly shorten operational time. Connect the red wire of the battery wire harness to the positive terminal of the first battery (Figure 1) and the black wire to the negative terminal of the second battery. Connect the black jumper wire to the remaining two terminals. Tape the batteries together (Figure 2) to prevent unnecessary movement. Figure 1 Figure 2 Insert the batteries on their side into the cutout section of foam in the bottom of the LCT-XX case. Orient the batteries so that the screw terminals are in the center of the case. Install the antenna BEFORE plugging the battery into the into ET board socket, as shown in Figure 3. NOTE: It is normal for the LCT-XX to transmit one to three “false” alarms right after the batteries are connected. It also transmits the first self-test within one minute of powering up. Figure 3 LCT-XX L5 USER’S MANUAL Page 6 of 19
VI. Encoder/Transmitter Settings All Encoder/Transmitter functions are set via the decimal-format rotary switches. To avoid damage to the switch, adjustments should ONLY be made with a standard, flat-blade 2.5 mm screwdriver. The triangle points to the current switch position. There are also detents at each position providing a tactile indication that the switch is properly set. Failure to have the switch settled in the detent will lead to erratic behavior. Switch functions are as follows: Channel: Valid settings are 1-8. Channel settings implement the channel frequencies that have been pre-programmed into the transmitter. Setting Channel select to 0 or 9 does not cause a malfunction; 9 is equivalent to channel 1, and 0 is equivalent to channel 8. Repeat: Valid settings are 0 through 3. 0 – No repeat. One message sent for every alarm or self test. 1 – 1 repeat. 2 messages total per alarm. 2 – 2 repeats. 3 messages total per alarm. 3 – 3 repeats. 4 messages total per alarm. Settings 4-9 are reserved. Setting Repeat to these positions will not cause the unit to malfunction, but should be avoided as they may be used to implement future diagnostic modes. Self-Test: Settings are 0 through 9. 0 – No self-test is sent. 1 – Self-test sent once per minute. 2 – Self-test sent once every five minutes. 3 – Self-test sent once every 65 minutes. 4 – Self-test sent once every 360 minutes (6 hours). 5 - Self-test sent once every 1500 minutes (25 hours). DEFAULT 6 – Self-test sent once every 25 hours w/transmit inhibit 5 seconds 7 – Self-test sent once every 25 hours w/transmit inhibit 10 seconds 8 – Self-test sent once every 25 hours w/transmit inhibit 15 seconds 9 - Self-test sent once every 25 hours w/transmit inhibit 25 seconds o The processor reads the self-test switch once a minute to check for a change in setting. When a change is detected the LCT-XX transmits a Port 4 alarm and the new self test interval begins. o Self-test transmissions begin within 60 seconds after the operator changes the Self-Test switch. o After an alarm is sent, the Transmit Inhibit, selectable by positions 6-9, prevents the LCT-XX from sending any alarms for the specified time. Address: Set the desired four-digit unit address, reading from top to bottom. The address can be any number between 0000 and 9999. LCT-XX L5 USER’S MANUAL Page 7 of 19
VII. Setting Gain Level Gain Switch Locations Gain switches adjust the sensitivity of the sensor. One (1) is the lowest gain level and eight (8) is the highest level. To select a gain, press the switch in towards the board. It is important to use ONLY the minimum gain needed for the area under surveillance to reduce the possibility of false alarms. For directional inputs, set both gain switches for a particular input to the same value. The picture above is for an LCT-DS. For LCT-DD transmitters, the Seismic Gain switches on the right are replaced by two sets of Directional Gain switches like those on the left. For LCT-SS transmitters, the two sets of Directional Gain switches on the left are replaced by a single bank of Seismic Gain switches. GAIN WARNINGS: • For Directional Gains, both the Right and Left channels must be set. • Gain for an unused input must be set to one for the LCT-XX to function properly. • There is no “zero” gain. If a gain is not selected, background noise is amplified by a factor of 700,000 rendering the LCT-XX inoperative until the gain is correctly set. LCT-XX L5 USER’S MANUAL Page 8 of 19
It is possible to select gain settings that are between the standard eight single-switch levels. Refer to table below for switch combinations and relative gain levels. Switch(es) Seismic Gain Level Directional Gain Level 1+2 0.28 3.38 1 0.37 5.1 2+3 0.81 6.67 2 1.1 10 3+4 2.2 12 3 3.1 20 4+5 4.8 17.7 4 7.5 30 5+6 9.9 27.3 5 13.5 43 6+7 27.3 42.9 6 37.5 75 7+8 60 60 7 100 100 8 150 150 Note: Contact Closure boards do not have gain settings. LCT-XX L5 USER’S MANUAL Page 9 of 19
VIII. Selecting Classify or Detect Mode In Classify Mode, the LCT-XX generates alarm codes based on the TYPE of signal the probe sees, regardless of the input source. Although there are special situations where two probes provide the most effective intrusion detection, Classify Mode is utilized primarily with a single probe to: • Discriminate between pedestrian and vehicular seismic signals • Determine direction of travel in front of infrared and magnetic probes In Detect Mode, the LCT-XX generates alarm codes based on which input SOURCE (J1 or J2) is stimulated, but does not distinguish the type (vehicle/pedestrian or direction of travel) of the signal. Detect mode can be used with either one or two probe inputs. NOTE: Contact Closure (CC) sensor boards do not have Classify/Detect modes. IX. Selecting Output Ports A sensor board’s output ports are the three lines of communication from it to the Encoder/Transmitter board. Alarm pulses generated by the sensor board are (or are not) sent to the Encoder/Transmitter board depending on which PORT SELECT switches are turned on. To turn a switch on, press it down towards the circuit board. Only select one Port for each function. Do not select duplicate Ports for different functions as this prevents the alarm from being sent. To prevent a particular function from being sent, do not select a Port for it. The Contact Closure (CC) switches are only used when a normally open contact closure probe is connected to J1 on LCT-DS and LCT-SS models. The pictures on the next page show the PORT SELECT switch assignments for all models except the LCT-CC which do not have selectable ports. LCT-XX L5 USER’S MANUAL Page 10 of 19

X. LCT-CC Contact Closure Transmitters The LCT-CC provides three sets of inputs for external devices that signal detected activity by means of opening or closing a switch. Unlike other LCT-XX models, there are no sensor board switches to set with these transmitters. Instead, alarm pulses are automatically assigned to the Ports associated with the inputs. For each of the three Ports, there is a normally closed pair of contacts in J1 and a normally open pair of contacts in J2. XI.

XIII. Deployment Tips A. LCT-XX • When changing batteries or settings, it is important to make sure that the case O-ring and mating surface are clean. Debris between the O-ring and mating surface creates a leak path which allows water to enter the unit. • The LCT-XX should only be buried deeply enough to cover the input connectors. If it is buried too deeply, the antenna’s signal is significantly attenuated. • Maximum transmit range is achieved when the LCT-XX has an unobstructed line of sight to the receiver’s or repeater’s antenna. When circumstances permit, use coax to remote-mount the antenna in an elevated location to improve performance in difficult terrain. B. Seismic Probes (SPS-21) • Although the probe’s cable is shielded, strong sources of electromagnetic energy can be conducted to the LCT-XX’s seismic amplifiers. Excess coiled cable should be placed under the unit to avoid picking up alarm transmissions. The unit should also be deployed away from other strong EM sources such as high-power transmission lines, power transformers, and radio towers. • To reduce the possibility of non-target alarms, deploy probes well away from sources of ground noise such as: heavy traffic; windblown trees, signs, etc.; pumps, compressors, and other machinery; livestock and animal trails. • Vibrations travel farther and retain more energy in hard or rocky ground. If the probe seems too sensitive with the LCT-XX on the lowest gain setting (switches 1 and 2 down), one or more of the following techniques should be used: o Use a shorter spike on the probe or eliminate it altogether. o Dig an oversized hole for the probe an fill it with a softer material like potting soil. o Connect an attenuator cable between the probe cable and transmitter to cut the signal in half. o Connect additional probes end to end to form a line string. Line strings may be composed of up to six probes. • Vibrations dampen out quickly soft or wet soil. To increase the probe’s sensitivity, replace the probe’s spike with a longer one or with a length of 3/8”-16 all-thread. LCT-XX L5 USER’S MANUAL Page 16 of 19
C. Dual-Axis Magnetometer Probes (MS-10) • Magnetic probes generate an alternating magnetic field and react to ferrous metals and other magnetic fields moving within that field. If the magnetometer is deployed above ground, it must be rigidly secured to prevent movement. Whether above or below ground, the MS-10 must not be deployed near sources of interference such as: windblown fencing, guy wires, signs, etc.; power lines and transformers; and electric motors. • Under certain circumstances, the temperature of the MS-10’s may be elevated above its operational limit of 60°C (140F°). This typically occurs during very hot weather and when the MS-10 is in direct sunlight or is shallowly buried in an unshaded area. If the probe gets too hot, false alarms may be generated. To eliminate false alarms, bury the probe a few inches deeper or deploy it in a shaded location. D. Passive Infrared Probes (PIR) • Passive infrared probes react to changes in temperature in the direction they are pointed. False alarms may be generated if the probe is pointed where there is background or animal movement, heat waves, or excessive incident light. • It is important that the probe be rigidly mounted so that its own movement does not cause false alarms. • NOTE: under no circumstances should an infrared probe be pointed where it will see direct or strongly reflected sunlight.
