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 that the runner is in distress, as loud as an ambulance siren and audible from over 600ft. This tiny alarm system is a deterrent and can alert others in case of an incident. Beyond that, we are offering core products (waist packs, armbands, phone carriers) with designated storage for the SaferRun Ripcord Siren.
