GENERAL INFORMATION:
The 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. Telbell 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.
Telbell is attractively packaged for convenient indoor or outdoor surface mounting. Wiring is easy because a modular telephone jack
is provided. Additionally it provides screw terminals for hard wiring, and a knockout for 1/2" conduit.
