TBB-1B
Talk Battery
Booster
January 3, 2017
The TBB-1B will boost talk battery
voltage up to 48VDC, and current up
to 26mA on single analog line
extensions behind PABX’s and
electronic key systems. This is
helpful for powering line powered
devices such as touch tone dialers
and emergency phones on low
voltage and/or low loop current
extensions.
When the TBB-1B is being used,
the power LED lights extra bright to
show activity. The TBB-1B is not
compatible with Pulse/Rotary dialing.
Power: 120VAC/12V DC 500mA, UL listed
adapter provided
Dimensions: 3.0” x 4.4” x 1.4” (76mm x 112mm
x 36mm)
Shipping Weight: 1.5 lbs (0.68 kg)
Environmental: 32° F to 90° F (0° C to 32° C)
with 5% to 95% non-condensing humidity
Loop Current to Device: 26mA (nominal)
Talk Battery Output: 48V DC (nominal)
Connections: (4) screw terminals

Installation
IMPORTANT: Electronic devices are susceptible to lightning and power station electrical surges from both
the AC outlet and the telephone line. It is recommended that a surge protector be installed to protect against
such surges.

Step 1. Open the plastic cover.
Step 2. Connect the analog extension to the LINE IN screw terminals.
Step 3. Connect the line powered device to the PHONE screw terminals.
Step 4. Connect the provided 12VDC adapter to the power jack.
Step 5. Snap the cover back into place.
The TBB-1B is designed to boost talk battery voltage and loop current of a single analog line. The
TBB-1B achieves this by creating its own 48VDC talk battery supply that is set up as a 26mA current
source. An analog phone line can be in three different states: the idle state, the ringing state, and the
in-use state. The TBB-1B operated these three states like this:
Starting with the idle state; no matter what the incoming talk battery voltage is, the TBB-1B will supply
48VDC talk battery out to the on-hook phone. This is helpful for devices such as alarm panels that want
to see high talk battery voltage as an indication the analog phone line is in good working condition.
In the ringing state, the TBB-1B provides a “copper-thru” path from input to output. This allows both
the ringing signal and caller ID signals to simply pass through the unit.
In the in-use state, the TBB-1B seizes the incoming analog line with a “gyrator” circuit, which provides
a DC off hook state to the incoming analog line. At the same time, allowing the AC audio signal to freely
pass through to the TBB-1B’s 26mA current source which is feeding the off hook phone device. So, no
matter what the incoming loop current is, the TBB-1B will output 26mA of loop current to the off hook
phone.
In the idle and ringing state, the TBB-1B power LED lights blue. When in the in-use state, the power
LED lights extra bright.

A. Low Loop Current
B. Low Idle Voltage
Alarm Panel Applications
Low loop current from a VoIP ATA, cable company, or telco provided phone lines can cause some
alarm panels to go into an alarm state due to very low levels at the phone when in-use. Solve this
problem by wiring a TBB-1B as shown below. The TBB-1B increases the in-use voltage.
Low idle voltage from a VoIP ATA, cable company or telco provided phone lines can cause some
alarm panels to go into an alarm state. Solve this problem by wiring a TBB-1B as shown below. A
TBB-1B increases the idle voltage, converting 24 volt lines to 48 volt lines.
