The SEMS PDA distress alarm warns the user when the air supply cylinder has reached 50% of its full capacity and also functions as an electronic end of service time indicator for the respirator by sounding an alarm when the air supply cylinder has been depleted to 25% of its full capacity. The Control Console digital display shows the approxi- mate cylinder pressure. Details of the end of service time indicator WARNING operation are also discussed in the Operation and Maintenance in- NO PERSONAL

BASIC FUNCTIONS OF THE SEMS EQUIPMENT The SEMS equipment has two primary functions: · Personal Alert Safety System (PASS) Distress Alarm · Evacuation Signal 1. The PASS Distress Alarm is joined to the SEMS PDA distress alarm operation. The Portable Unit will send a signal to the Base Station when the SEMS PDA distress alarm goes into full alarm. Activation of the full alarm can be either by manual activation of the user or by automatic activation from lack of user movement for the time period se

MANUAL OPERATION OF THE SEMS PDA DISTRESS ALARM With proper batteries installed and a charged air cylinder, the SEMS PDA distress alarm (PASS) is automatically activated when the respi- rator is pressurized by opening the cylinder valve of the respirator. If batteries are completely discharged or have not been installed, there will be no light or sound indicating that the unit will not work at all. Activation is indicated by 3 quick audible chirps from the Sensor Mod- ule. On activation, a gree

Once activated, the SCOTT SEMS PDA distress alarm will remain activated until: 1. The respirator air cylinder is turned off with the residual air pres- sure purged from the regulator AND 2. The reset button on the control module has been pressed twice. In the automatic mode the SCOTT SEMS PDA distress alarm con- stantly monitors motion of the respirator backframe. The motion sen- sor is located in the Sensor Module along with the audible alarm. If the Sensor Module does not sense motion of th

MANUAL ALARM: If the respirator user is in a situation where immediate assistance is required, the SEMS PDA distress alarm provides a manual alarm but- ton, located on the front of the Control Console on the user’s right shoulder, shown in FIGURE 2. The manual alarm causes the Full Alarm signal to be given. The manual alarm may be activated at any time by pressing the manual alarm button and holding at least two seconds, even when the respira- tor is not pressurized, provided a good battery is

USE OF THE SEMS PDA PORTABLE UNIT Users of SCOTT respirators equipped with the SEMS PDA Portable Unit must be fully trained in the operation of the equipment as part of a complete respiratory protection program before entering a hazard- ous environment. 1. Start-up a) Use of the SEMS PDA Portable Unit begins when the user opens the cylinder valve on the respirator to start respirator usage. The unit will sound three chirps to indicate activation. b) After a brief start-up sequence of less than
