Page 10 of 28P/N 595277-01 Rev E 10/17PRE-ALARMIf the respirator remains motionless for more than twenty (20) seconds, the PAK-ALERT distress alarm will automatically sound a pre-alarm When the pre-alarm occurs, the green ashing light on the control console is replaced by a bright red light which ashes in cadence with pre-alarm tone and is accompanied by an ascending/descending audible tone which increases in volume during the pre-alarm cycle. In addition, the lights in the Heads-Up Display will ash alternately from one side to the other.If the respirator user is not incapacitated or not in need of assistance, move the respirator to reset the pre-alarm. When reset, the ashing red light will be replaced by the ashing green, the ascending/descending tone will stop, and the Heads-up Display will return to showing the current cylinder pressure.Remember that the motion sensor is in the Sensor Module on the respirator backframe beneath the air cylinder. Actual movement of the respirator back-frame is required to reset the pre-alarm. Shaking the control console will not reset the PAK-ALERT distress alarm .To manually reset the pre-alarm, press and hold the reset button on the side of the control console until three (3) quick audible chirps are heard and the red ashing light on the control console is replaced by the green ashing light. FULL ALARMIf the respirator remains motionless through the twelve (12) second pre-alarm cycle, the PAK-ALERT distress alarm will go into full alarm. This may indicate that the user is incapacitated or in need of assistance and can not move.Full alarm is indicated by a loud, almost continuous 3 tone chirp from the Sensor Module accompanied by the ashing red signal light on the control console. Ten (10) seconds after the full alarm condition starts, the Locator Transmitter will begin to transmit the unique ID number for the unit. After an additional (10) second delay, the Pak-Tracker Locator transmitter in the unit will begin transmitting the unique ID number that can be received by the Pak-Tracker Hand Held Unit. To reset the full alarm condition, press the reset button twice. See FIGURE 4.After the full alarm has been silenced by pressing the reset button twice, the PAK-ALERT distress alarm will remain activated in the automatic mode with the green light ashing once per second. As long as the respirator is pres-surized, there must be movement of the respirator at least every twenty (20) seconds or the distress alarm will again go into pre-alarm followed by full alarm as described above.MANUAL ALARMIf the respirator user requires immediate assistance, pressing the manual alarm button located on the front of the control console will immediately sound the full alarm. See FIGURE 4. The manual alarm may be activated at any time, even when the respirator is not pressurized. If the manual alarm is activated when the respirator is not pressurized, press the reset button twice to silence the alarm. The PAK-ALERT distress alarm will remain on in automatic mode. To turn the unit off, press the reset twice again while the unit is not in alarm mode. In manual alarm mode, the Pak-Tracker Locator transmitter in the unit will begin transmitting the unique ID number that can be received by the Pak-Tracker Hand Held Unit with NO delay.Remember, the loud audible alarm and ashing red light can be turned on at any time by pressing the manual alarm button on the control console.WARNINGUSERS OF RESPIRATORS EQUIPPED WITH THE PAK-ALERT DISTRESS ALARM MUST BE AWARE OF THE PROPER OPERATION OF THE DISTRESS ALARM.

In low battery condition, the PAK-ALERT distress alarm will not emit the 3 beeps when cylinder valve is activated.While in low battery condition, the PAK-ALERT distress alarm will continue to operate for a period of time greater then the longest duration cylinder available for the respirator. However, the batteries must be replaced before the respirator is used again. See THE BATTERY REPLACEMENT section of these instructions.If batteries are completely discharged or have not been installed, there will be no light or sound and the unit will not operate.BATTERY TESTTo test the batteries, verify that the PAK-ALERT distress alarm is in the off condition (cylinder valve closed with no ashing green LED on the control console). Press and hold the reset button on the console.A green light on the console will illuminate to indicate sufcient battery power remaining. If a red light appears, the batteries must be replaced before the respirator is used again.TO TURN OFF THE PAK-ALERT DISTRESS ALARMWhen use of the respirator with the PAK-ALERT distress alarm is no longer required, close the cylinder valve on the respirator and vent the residual air from the respirator system by opening the regulator purge valve. After all the air ow stops, close the regulator purge valve and press the reset button twice to turn off the PAK-ALERT distress alarm. If there is air pressure left in the system, the green ashing light will continue to ash while a fteen second beep sequence is heard from the Sensor Module as the residual air bleeds from the system. As soon as the air has completely bled from system, the unit will sound a quick two tone chirp and the PASS DEVICE distress alarm will be inactive. If there is no pressure in the system when the RESET button is pressed twice, there will be no fteen second beep sequence. When the unit sounds a quick two tone chirp, the PAK-ALERT distress alarm is inactive. If there is any air pressure left in the system, the PASS DEVICE distress alarm will return to the active mode.If the respirator cylinder valve is open and/or pressure remains in the respira-tor, the PAK-ALERT distress alarm can not be turned off. Pressing the reset button when the respirator is pressurized will only reset an alarm condition and return the PAK-ALERT distress alarm to automatic mode.If the respirator cylinder is turned off and depressurized without pressing the reset button twice, the PAK-ALERT distress alarm will continue to monitor motion in automatic mode. This means that the PAK-ALERT distress alarm may be used to monitor motion after the respirator is turned off and depres-surized. Resetting the full alarm after the respirator has been depressurized will not turn off the PAK-ALERT distress alarm. Press the reset switch twice with no alarm condition to turn off the PAK-ALERT distress alarm (there will be no fteen (15) second beep sequence and two tone chirp will be heard).DRAFT NOT FOR DISTRIBUTION

Refer to the PAK-TRACKER Locator System User Instructions provided with your PAK-TRACKER equipment for complete details on the use of the PAK-TRACKER Locator System. Use of this equipment must be part of a complete personnel accountability system that includes procedures for monitoring the deployment and condition of all users. Do not rely on the PAK-TRACKER Locator System as the only tech-nique for locating missing personnel. A Rapid Intervention or Rescue team using the Hand Held Receiver must have a minimum of two (2) people. For their own safety, the team members must pay attention to their surroundings at all times while using the PAK-TRACKER Locator System.The accountability system must include procedures for alerting the incident commander and rescue teams when actuated transmitters or the missing personnel have been found or when they have moved from their previous location. It is the responsibility of the personnel accountability system to allow for such contingencies without exposing individuals and teams to unneces-sary dangers.WARNINGCONTINUED TRAINING AND PRACTICE IN A VARIETY OF SITUATIONS IS ESSENTIAL TO DEVELOPING THE SKILLS TO PROPERLY INTERPRET THE INFORMATION PROVIDED BY THE PAK-TRACKER LOCATOR SYSTEM. USE OF THIS EQUIPMENT WITHOUT TRAINING AND PRACTICE MAY JEOPARDIZE ALL PERSONNEL INVOLVED WHICH COULD LEAD TO SERIOUS INJURY OR DEATH.PRINCIPLES OF OPERATION OF THE PAK-TRACKER LOCATOR SYSTEMThe SCOTT PAK-TRACKER locator system is a two part electronic system consisting of a Hand Held Receiver and a Transmitter. When a Transmitter is activated, it sends out a radio signal in all directions that is received by the Hand Held Receiver. Understanding how the radio signal from a Transmitter behaves and how the Hand Held Receiver receives and displays the strength of that signal are critical to understanding the operation of the SCOTT PAK-TRACKER locator system. Successful operation of the PAK-TRACKER Locator system depends heavily on the interpretation of the relative signal strength information displayed on the Hand Held Receiver along with all other available information about the possible location of the activated transmit-ter. The Hand Held Receiver is very sensitive in responding to small differences in signal strength. The relative strength of the Transmitter signal detected by the Hand Held Receiver will vary depending on:1. The distance from the Transmitter to the Hand Held Receiver, 2. The path the Transmitter signal has taken to get to the Hand Held Re-ceiver,3. The materials between the Transmitter and the Hand Held Receiver which may have affected the signal from the Transmitter. The user of the Hand Held Receiver must interpret the readings on the Hand Held Receiver display along with other information, such as:– training and knowledge in systematic search and rescue techniques,– their sense of sight (watch where you are going),– their sense of sound (listen for an activated PASS device), – the deployment of the missing personnel, – knowledge of the building layout and building materials, Do not rely solely on the readings from the Hand Held Receiver to locate the activated Transmitter. Refer to the PAK-TRACKER Locator System User Instructions provided with your PAK-TRACKER equipment for complete details on the use of the PAK-TRACKER Locator System.USE OF THE OPTIONAL SCOTT PAK-TRACKER LO-CATOR SYSTEM WARNINGREAD AND UNDERSTAND THIS ENTIRE MANUAL AND THE PAK-TRACKER LOCATOR SYSTEM MANUAL.

DETECTING AND AVOIDING RADIO FREQUENCY INTERFERENCEWhen any electronic device is adversely affected by radio waves, Radio Frequency Interference (RFI) is said to have occurred. All electronic devices like the PAK-ALERT distress alarm may be subject to the effects of RFI. Ra-dio transmissions from the antennas of radios including those used by re ghters, police and other public safety related personnel may produce RFI in the PAK-ALERT distress alarm. RFI may occur while the radio is transmit-ting if the respirator equipped with the PAK-ALERT distress alarm is in close proximity to a base station or high-powered vehicle mounted radio, or if the antenna of a personal portable hand held radio is touching or within six (6) inches of the Control Console or Sensor Module of the PAK-ALERT distress alarm. See FIGURE 5. Be aware of the symptoms of RFI. A PAK-ALERT distress alarm affected by RFI may temporarily give false indications such as the sudden sounding of the loud continuous three-tone chirp of the full alarm. In some instances the lights on the control console may ash without sounding the alarm. In rare circumstances, an alarm which was sounding may stop.If the PAK-ALERT exhibits any of the symptoms of RFI, identify the source of the RFI and do the following:– If the symptoms of RFI occur when standing near a base station trans-mitting antenna or a truck mounted radio antenna, move away from the antenna until the symptoms stop. – If the symptoms of RFI occur while transmitting on a hand-held radio, move the radio away from the PAK-ALERT . CHECK THE CONTROL CONSOLE AND BE CERTAIN THE GREEN LIGHT IS FLASHING NORMALLY WHEN THE INTERFERENCE STOPS, REGARD-LESS OF THE SOURCE.In normal usage with the air cylinder open, the PAK-ALERT distress alarm DRAFT NOT FOR DISTRIBUTION
