The PASS device sounds a loud (95 <a href="/wiki/Decibel" title="Decibel">decibel</a>)<sup id="cite_ref-NFPA1982_1-0" class="reference"><a href="#cite_note-NFPA1982-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> audible alert to notify others in the area that the firefighter is in distress. On a fireground, the sound of an activated PASS device indicates a true <a href="/wiki/Emergency" title="Emergency">emergency</a> and results in an immediate response to <a href="/wiki/Rescue" title="Rescue">rescue</a> the firefighters in distress. In the United States, the <a href="/wiki/National_Fire_Protection_Association" title="National Fire Protection Association">National Fire Protection Association</a> sets standards for PASS devices in NFPA 1982.<sup id="cite_ref-NFPA1982_1-1" class="reference"><a href="#cite_note-NFPA1982-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>The PASS device is normally used in conjunction with breathing apparatus; it is a small, battery-powered device attached to the <a href="/wiki/Self-contained_breathing_apparatus" title="Self-contained breathing apparatus">self-contained breathing apparatus</a> (SCBA) harness which enables the firefighter to summon help by activating a loud, piercing electronic bleeper. </p><p>Early models were only able to be activated manually, such as when a firefighter is lost or trapped. More recent PASS devices can also automatically activate if the device does not detect motion for 30 seconds,<sup id="cite_ref-NFPA1982_1-2" class="reference"><a href="#cite_note-NFPA1982-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> so that the alert will sound if the firefighter is seriously injured or otherwise incapacitated. Some devices use a ball bearing on a track to sense firefighter movement and others use an <a href="/wiki/Infrared" title="Infrared">infrared</a> beam against a mirror mounted on a spring. When activating for a lack of motion, the PASS device will typically emit a few seconds of a muted warning that activation is about to occur,<sup id="cite_ref-NFPA1982_1-3" class="reference"><a href="#cite_note-NFPA1982-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> so that a firefighter who has simply been motionless for a time but is otherwise safe will be able to move slightly and thus reset the activation timer before a false activation occurs. </p><p>Older models of PASS devices required manual arming by firefighters prior to entering a dangerous environment. The unit was equipped with a key which, when removed, armed the unit. This key was left outside the hazard area with an entry control officer. When the unit activated, it could only be switched off by inserting this key. Current applications integrate the PASS device into the SCBA worn by firefighters so that it automatically arms when the SCBA air supply is engaged or when the SCBA is removed from its mounting bracket. This style devices are powered by <a href="/wiki/Battery_(electricity)" class="mw-redirect" title="Battery (electricity)">battery</a>, are easily activated while wearing gloves, and are <a href="/wiki/Intrinsically_safe" class="mw-redirect" title="Intrinsically safe">intrinsically safe</a> to operate in flammable or explosive atmospheres. </p><p>It was reported that shortly after the events of <a href="/wiki/September_11_attacks" title="September 11 attacks">September 11, 2001</a>, the sound of many activated PASS devices could be heard beneath the rubble of the collapsed <a
