The COOPER-WHEELOCK-TB-593 telbell is designed to provide a loud attention getting bell sound for use in noisy locations or for wide area coverage. It includes an externally adjustable, tamper resistant volume control.

The TB-593 utilizes the motor driven mechanism concept that incorporates a high torque permanent magnet motor and a 6″ aluminum shell to produce higher sound output and lower resonant frequency than conventional mechanical bells.

The TB-593 is FCC registered for use with the public telephone network, PBX and key systems that use interrupted ring voltages from 55-130VAC, 20-30Hz. The unit is packaged for convenient indoor or outdoor surface mounting.
