The all new, state-of-the-art DB 200 doorbell/telephone and intercom signalers requires no wires and can be installed in seconds. The DB 200 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 phone cord simply plugs into any telephone jack. The DB 200 has a built-in outlet to flash an attached lamp and each sends a signal to all Sonic Alert remote receivers.
Add more lamps to flash in other rooms by plugging in the wireless SA201 Deluxe Remote Receiver....or add flashing bright Strobe Lights by plugging in the wireless BL300 Sonic Blink Remote Strobe Receiver.
Add extra loud adjustable audio in other rooms by plugging in the wireless RH-100 Sonic Siren Loud Audio Receiver.
