The DB100 and DB200 made by Sonic Alert, are unlike competing models, they are not triggered by sound, so false alarms will not happen. Other updated features include: Selectable number of flashes (5 or 10), Different flash code for front door, rear door, or intercom (requires additional sensor, sold separately), and a built-in chime for hearing members of the family that can be turned off.
