ABSTRACT:
An electronic audible warning device (10), which includes a power source (18), a motion detector (401), a pleasant tone generator (100, Q1, Q3), a loud piercing tone generator (100, Q1, Q2) and a remote push button activation switch (19) is disclosed. Signaling device (10) provides two distinct features, each responsive to remote activation switch (19). A single depression on push button switch (19) will sound an unobtrusive, pleasant sounding two second pulsating warning tone. Two consecutive pushes on push button (19) will sound an attention-getting pulsating signal, similar to the backup beeper on commercial trucks, which will continue to sound until button (19) is pressed again. An additional feature is provided which is responsive to a motion detector (401). Here, a loud, piercing tone is sounded whenever a bicycle (1) or similarly attached article is moved. The alarm is activated and deactivated via an electrical key switch (402) which is installed directly in main housing (11).
