Magnetic-Contact Door Chimes
No electricity or batteries are needed—as your door opens, the magnet and contact disc are separated, sounding a mechanical chime. The chime can be deactivated.

Motion-Sensing Door Chimes
A chime announces when someone passes through the infrared light beam and a counter keeps track of each entrance and exit. Mount the transmitter and beam reflector between 2 and 20 feet apart. The chime's volume is adjustable up to 85 dB. It cannot be sold to California due to local energy efficiency regulations.
Additional chimes (sold separately) can be added to the transmitter.
