The BB133 Battery Back-up Kit is
designed for use with our Addressable Amplified
Speakers.
The Kit allows the
2.8 Ah battery (included) to be installed inside the
speaker housing. It will provide nearly 3 hours of
full power output from the speaker if input power is
lost. It is also ideal for short term battery only
operation for temporary usage.
