Night Vision Personal AlarmTM Flashlight: Red LED lights are good for night illumination without altering your eye's natural dark vision adaption. Use the red LED press-and-hold button for immediate vicinity illumination. When you turn off the red illumination your eyes don't have to adjust back to the darkness.
135dB Alarm : 135dB Peak volume at source (<1 inch), 130dB RMS volume at distance of 3m. This is one of the loudest personal alarms manufactured by Vigilant for sale in the United States.
Rip Cord Activation : This alarm uses the Vigilant Help CordTM grenade pin style activator. Simply pull the rip cord to activate the alarm. The only way to silence it is by replacing the grenade-style pin.
Batteries : Pre-loaded and user replaceable LR44 alkaline (button type) batteries are included.
About the 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. 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.
