MODEL NO: TB-591, TB-592

GENERAL:

The TB series Telbells are 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 series are designed for use with telephone communications systems whose
ringing voltages are from 18-30VAC/DC, or 38-60VDC.

Telbells are attractively packaged for convenient indoor or outdoor surface mounting. Wiring is easy because a modular telephone
jack is provided. Additionally, they provide screw terminals for hard wiring, and a knockout for 1/2" conduit.

READ THESE INSTRUCTIONS CAREFULLY BEFORE USING THIS PRODUCT.

then plug the bushing into the backbox per Figure 2.

e. Test by having someone ring your telephone to make sure the signal functions properly.

NOTE: The factory volume control setting is at maximum. Readjust volume as required. For tamper resistant volume setting,

remove volume control shaft by pulling straight out.

2. Hard Wire Connection - Figures 3 & 4:
a. Unscrew the center bolt to remove the bell shell.
b. Remove the bell housing by unscrewing all four screws. Disconnect the red and black wires by unplugging from the PC

Board.
c. Mount the backbox to the desired location, using mounting hardware suitable for the mounting surface material.
d. No conduit:

Route the 24VDC or 48VDC wires through the bushing (provided) and connect wires to terminal TB1 marked T and R

respectively. Then plug the bushing into the phone jack opening of the backbox, See Figure 4.

With conduit:

Open the knock-out in the top of backbox. Be careful not to damage PC Board components. The knock-out opening is

sized for 1/2" conduit and matching connector. Be sure that proper water tight conduit fitting is used to connect to the bell

backbox for outdoor application. Connect 24VDC or 48VDC wires to terminal TB1 marked T and R respectively.

i. Test by having someone ring your telephone to make sure the signal functions properly.

NOTE: -The factory volume control setting is at maximum. Adjust volume as required. For tamper resistant volume setting,

remove volume control shaft by pulling straight out.

- At low input voltages, and low volume settings, the volume control may have to be adjusted to obtain the desired sound
