The transmitter is factory pre-set to a single (customer specified) channel. See frequency range below. Channel: Factory Pre-Set Single Channel Sensor Connecto r Battery Cap Antenna ID Codes: 00-63 (Even numbers only for normal use, all numbers for special applications.) Antenna: Wire Whip, ¼ Wave Frequency Range: 138-174 MHz Power Supply: 1-2 each 9 V DC Batteries (MN1604) Battery Life: 4-6 months in temperate climate Sensor: Any Qual-Tron sensor Pin Connections: A: Ground B: +9 VDC C: Tx Trigger D: ID Code Control (do not use) Design Features • ID code selection (Switches inside battery compartment) • Internal power ON – Normal operation – Antenna up • Internal power OFF – Non operating – Battery cap down • Internal power ON – Sensor alignment – Battery cap up • Transmit ID code alarms • Sensor Fault alarms • Sealed battery compartment • Four pin Mil-Type (sensor) connector • Potted and sealed electronic components • Injection molded lexan plastic housing • Metal battery cap clamps with heat welded screw inserts • Frequency matched antenna QTI Page 3 Revision: C Form #: 30Z0147 Effective Date: 24 August 2006 Operation ID Code Set-Up – The ID is the number transmitted when the attached sensor is activated. The ID number transmitted is the sum of the switches, 8A + B. These switches should be set with the screwdriver provided to prevent damage to the plastic slots. Use only even number ID codes between 00-62. Example: ID Code 30 (A) x8 position = 3; (B) x1 position = 6; = (8 x 3) + (1 x 6) = 24 + 6 = 30 (ID number 30 will be transmitted) ID Switch Setting Chart ID X8 x1 ID x8 x1 ID x8 x1 ID x8 x1 00 0 0 16 2 0 32 4 0 48 6 0 02 0 2 18 2 2 34 4 2 50 6 2 04 0 4 20 2 4 36 4 4 52 6 4 06 0 6 22 2 6 38 4 6 54 6 6 08 1 0 24 3 0 40 5 0 56 7 0 10 1 2 26 3 2 42 5 2 58 7 2 12 1 4 28 3 4 44 5 4 60 7 4 14 1 6 30 3 6 46 5 6 62 7 6 Note: For all applications use even ID codes only. When a sensor fault occurs (if the connection between the transmitter and sensor is broken for any reason), the transmitter will activate and transmit the next higher odd ID number. Example: If the normal ID code is 20, then 21 would be transmitted when a sensor fault occurs. This would advise the user of …

TITLE: MXMT OPERATIONAL/ TECHNICAL DESCRIPTION INTRODUCTION Qual-Tron, Inc. of Tulsa Oklahoma manufactures a full range of unattended ground sensors and monitoring systems used to detect intrusion activity. The mechanical and electrical sensors include Breakwire, Magnetic, Seismic, IR Break Beam, Passive IR Sensors and Hydrophones. These sensors are used in combination with the MIDS single channel system, MIDS-II (modified) single channel system and EMIDS Multi-channel system. These systems utilize transmitters, relays and receivers to provide digitally encoded messages of alarm activity. Qual-Tron also manufactures base station equipment, power supplies and auxiliary equipment to provide a complete functional system. PURPOSE The purpose of this document is to provide a brief description of the circuit functions of the MXMT MIDS Single Channel Transmitter along with a statement describing how the MXMT operates. A description of the ground system and antenna is also discussed. MXMT OPERATIONS The MXMT is a MIDS single channel, fixed frequency transmitter. It is capable of transmitting 32 separate ID codes. During normal operation, the transmitter is triggered by an external sensor. The transmitter has built-in features to allow alignment of the PIR – Passive Infrared Sensor and MBBD – IR Break Beam Sensor. Once batteries are installed, built-in switches determine alignment and operational mode. When triggered by a sensor, the MXMT transmits a 20-bit digitally encoded packet. The packet includes a two digit ID code, along with a 4-bit message type. A fault message is automatically transmitted for any sensor disconnect. The MXMT is compatible with all Qual-Tron sensors. CIRCUIT FUNCTIONS BLOCK 1: The transmitter is triggered by a momentary positive pulse, typically 5 Volts from a sensor. This trigger sets a monostable counter which enables the transmitter and the encoder circuitry for approximately 50 milliseconds (19 Hz). The encoder uses a 19.2 KHz oscillator to DRN DATE SIZE A CODE IDENT 2N899 DOCUMENT NAME MXMT FCC Operational T echnical.doc REV A CKD DATE The information contained in this document is considered proprietary and is the sole and exclusive property of Qual-Tron, Inc.

TITLE: MXMT – OPERATIONAL TECHNICAL DOCUMENTATION APP DATE SCALE N/A WEIGHT N/A PAGE 2 OF 2 generate a 1200 baud Manchester code that includes 8 bits of preamble, a start bit, a message type, a selectable ID code and an odd parity bit. This encoded message is used to modulate an FSK transmitter. BLOCK 2: The modulation input into the FSK modulator is used for deviation of the crystal Y1 +/- 333 Hz. The crystal range of Y1 for the low band is set per customer order in the range 15.333 MHz to 17.00 MHz. This modulated signal is then multiplied using two tripler circuits. This dual tripling multiplies the frequency by 9 to provide a 138 MHz – 154 MHz output with a deviation of +/- 3 KHz. The signal is then fed into the Power Amp, which is set for 1 watt output. The antenna is a simple wire whip stub antenna screwed into the enclosure. MODULATION SYSTEM DESCRIPTION The modulation of this system employs Frequency Shift Keying at 1200 Baud. The transmission of data is typically event driven in short-bursts of 25 ms or less. The modulation uses a 20-bit Manchester code that includes 8-bits of preamble, a start bit, 4-bit message type, 6-bits of ID and a parity bit.

It is capable of transmitting 32 separate ID codes. During normal operation, the transmitter is triggered by an external sensor. The transmitter has built in features to allow alignment of the PIR and MBBD sensors. Once batteries are installed, built-in mercury switches determine alignment, operation, and can also turn off the transmitter. A fault message is automatically transmitted for any sensor malfunctions. The MXMT is compatible with any Qual-Tron sensor. (NOTE: Specify operating frequency when ordering.)
