LINEAR LLC FCC ID:EF4LRP FUNCTIONAL DESCRIPTION 1.0 DESCRIPTION The DXS-LRP is a one channel, fixed or semi portable emergency signaling transmitter operating as a low power communication device. The center frequency is crystal stabilized at 315.00 MHz. The data output is Linear DX Code formatted. The DXS-LRP and the DX Code format are designed for use with Linear DX format 315 MHz receivers and consoles. Typical receivers that could be used with this transmitter are the DXR-701, DXS-702, DXSR-1504/8, DVS-1200/2400, Dual 824 and PERS-3600. Each DXS-LRP is programmed with a DX format factory ID code. The DX format code gives over 1 million possible transmitter IDs. One lithium coin cell batteries, type 2032 is included. The battery should last about 4 years under normal use. If the transmit push button is pressed four times during a time of 4 seconds, the DXS- LRP will go into a supervisory mode. It will thereafter send status transmissions every 2.0 hours. This supervisory signal will continue until the transmitter’s battery is exhausted. 2.0 FUNCTION When the push button is depressed, U1-4 becomes low and activates U1's program. The program provides a latch signal to keep the microprocessor alive until a minimum of 8 words (800 milli second duration) are transmitted. After the 8 words are transmitted and if the switch is now open, the processor turns off. If the button is held down for more than 30 seconds, the transmitter's output is disabled. When U1 wakes up, it outputs signals to turn on the oscillator IC U3 and to provide DX coded data. The frequency of oscillator U3 is stabilized at 315 MHz by a divide by 32 crystal time base, Y1. Data output at U1-6 modulates U3 which transmits the pulse- modulated carrier via the antenna. The battery voltage is supervised by voltage detector U2. If the nominal 3.0 Volt battery Voltage drops below 2.7 Volts the transmissions will include a low battery signal. 3.0 SPECIFICATIONS Product Identification: DXS-LRP transmitter (SST00122). Encoding Format: Linear DX Code. Encoding Technique: Transmitters are factory coded with a sequential transmitter ID number. LINEAR LLC FCC ID:EF4LRP Number of Channels: One Timing: Transmission stops after 30 seconds when button is held on. When momentarily activated the transmitter sends a minimum of 8 data words (800 milli seconds transmission). RF Carrier Frequency: 315.00 MHz  20 KHz. Power Requirements: One 2032 3 volt battery. Visual Indicator: Dual color display, green / red LEDs Green Steady – Battery OK Red Steady – Low Battery Green or red blinking (at end of a transmission – Tx is in supervisory mode . Operating Temperature: 0 C to +70 C. Tested –30 C to 70 C. Size: 1.2" x 2.0" x 0.3” Current Consumption: 10 mA (average) transmitting. <5 uA Standby. All specifications are nominal unless otherwise noted.

A test site submittal is on file with Industry Canada. The Industry Canada file number is 1078A-1. The file is dated August 4, 2010.

Date Regulatory Compliance Engineer DURATION OF RF TRANSMISSIONS LRP REMOTE CONTROL TRANSMITTER This transmitter is manually activated. Typically, it is used for remote control of a security system. As such, it may be operated continuously by the user (FCC Rules 15.231(a)(4)). However, due to battery constraints and an accidental continuous activation causing interference to the system, the maximum manually activated transmission for a single press of a pushbutton is 30 seconds. When a push button is quickly pressed but then released, the transmitter will cease transmitting only after a minimum of 8 data words (8 words X 100 milli-second/word = 800 milli-seconds minimum transmission) have been sent. FCC Rules 15.231 (a)(1) allows no longer than 5 seconds upon the release of a manually activated transmitter. Signed: John W. Kuivinen, P.E.

MEASUREMENT OF RADIO FREQUENCY EMISSION OF CONTROL AND SECURITY ALARM DEVICES FCC RULES PART 15, C63.4-2003 TEST PROCEDURE I. INTRODUCTION As part of a continuing series of quality control tests to ensure compliance with all applicable Rules and Regulations, this enclosure details the test procedures for certain radio control devices. Testing was performed at a test site located on the property of Linear LLC, 1950 Camino Vida Roble, Suite 150, Carlsbad, California 92008-6517. II. MEASUREMENT FACILITY DESCRIPTION The test facility is a specially prepared area adequately combining the desirability of an interference free location with the convenience of nearby 120 volt power outlets, thus completely eliminating the incidence of inverter hash, so often a problem with field measurements. III. DESCRIPTION OF SUPPORTING STRUCTURES For Measuring Equipment - The antenna is supported on a trolley that can be raised and lowered on a mast by means of remote control to any level between 1 meter and 4 meters above the ground. For measurements at 3 meters, an antenna height (center of dipole) of about 1 meter generally yields the greatest field strength. For measurements at 1 meter, an antenna height equal to the device under test generally yields the greatest field strength. Usually, horizontal polarization yields the greatest field strength for both 1 and 3 meter measurements. For Equipment Under Test (EUT) : The equipment to be tested is supported by a wooden turntable at a height of eighty centimeters. A two axis swivel at the top of the turntable permits the unit under test to be manually oriented in the position of maximum received signal strength. The turntable can be rotated by remote control. Test Configuration - All transmitters were located eighty centimeters above ground, at a distance of three meters from the antenna. They were each oriented for maximum radiation by rotating the turntable. The antenna was then moved vertically along the mast for optimum reception in both horizontal and vertical planes. Where no emissions were found, the antenna was also moved to one meter distance to improve system sensitivity. All receivers were located eighty centimeters above ground, at a distance of three meters from the antenna. They were each oriented for maximum radiation by rotating the turntable. The ante…
