The SaferRun Ripcord Siren Personal Alarm is a thumb-sized device that blasts sound in case of emergency. A simple pull of a tab will sound a 120dB alarm, as loud as an ambulance siren and audible from over 600 ft. away. This tiny alarm system is a deterrent and can alert others in case a runner or walker is in distress. Compatible with core Nathan products (waist packs, armbands, phone carriers) with designated storage for the SaferRun Ripcord Siren.
