With multiple functionalities built into one device, DS-R3 is in a class of its own. Designed for emergency evacuations, it can also act as location beacon as well as a high capacity (low latency) BLE Mesh node. It is completely wireless and can sound an alarm via its very loud 110 decibel siren and flashing strobe lights, bringing attention to the workforce in a noisy environment. It can be connected to an AC outlet (110-220V) and/or use its internal rechargeable battery (9,600 mAh). It can be affixed to locations via screws, magnet, cable tie or double-sided adhesive tape.
