Panel-Mount Miniature Buzzers
Styles A and C are also known as piezo buzzers.
For Styles B and C, the volume increases as voltage increases.
Buzzers with a pulse tone alternate on/off to draw greater attention than buzzers with a continuous tone.
Buzzers with both a continuous and pulse tone can be wired to trigger two alerts, each corresponding to a different warning. If the continuous and pulse tone are both triggered at the same time, only the continuous tone will sound.

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.
