Description

Vigilant's Loudest Personal Alarm with Night Vision Red LED and Rip Cord Activation

The PPS-13BL is one of the loudest alarms ever manufactured by Vigilant at 135dB peak volume with a breakthrough high resonant circular design. It uses Vigilant's Help Cord activation, including a rip cord with grenade style pin for easy and decisive activation in any emergency. This Night Vision Personal Alarm includes a red LED light for immediate vicinity illumination. The palm-sized PPS-13BL includes a wrist / tether strap with an included bag clip. Batteries are also included, pre-loaded, and user replaceable.

Circular Resonant Design

 

Vigilant's engineers have created a better, higher performance acoustic design.  Sound waves travel outward from a speaker.  The PPS-13BL is circular (like a speaker) so that the sound can build volume and crescendo from the speaker on the front of the device. Similar to an ambulance siren that projects the sound forcefully, the new design saturates the area in front of the PPS-13BL circular speaker with piercing resonating sound.  

In physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies. Frequencies at which the response amplitude is a relative maximum are known as the system's resonant frequencies or resonance frequencies.  The PPS-13BL is built to extract the maximum resonance of the alarm at a frequency perfectly tuned to create what your ear will hear as the loudest alarm noise possible from it's palm sized case.  The design of the PPS-13BL produces more resonance (prolongation of sound) than a typical alarm.  The result is exactly what you want it to be - a cringe-worthy, painfully loud emergency alarm.
