Sonic Alert WIRELESS Doorbell Transmitter w/Button DB-100 $99.95
The all new, state-of-the-art, DB 100 doorbell and intercom signalers require no wires and can be installed in seconds. The DB 100 is not triggered by sound, so annoying false alarms are a thing of the past. Other advanced 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 (can be turned off). The DB 100 has a built-in outlet to flash an attached lamp and each sends a signal to all Sonic Alert remote receivers.
