PRODUCT DESCRIPTION
The VB-4B Audio Module is designed as an add-on accessory for the
PERS-2400B Personal Emergency Reporting System Consoles. The
module plugs directly into the Console’s circuit board connectors.
A digitally synthesized human voice produced by the VB-4B module
announces important system information through the Console’s speaker.
The volume control adjusts the voice level.
The VB-4B features 2-way audio (manual and full duplex) and audio listenonly capabilities for Central Station monitoring. The small microphone
supplied fi ts into the Console’s case. The module’s high-gain amplifi er
allows the Central Station to monitor the sounds in the installation after
an alarm. In 2-way full duplex mode, the Central Station operator can talk
back to the subscriber through the Console’s speaker. In 2-way manual
mode the Central Station operator can control the direction of the 2-way
communications using a pushbutton telephone.
The Model RSM-1 Remote Speaker/Microphone can also be used with
the VB-4B to increase its audio coverage area.

IMPORTANT!!!
Linear radio controls provide a reliable communications link and fi ll an important
need in portable wireless signalling. However, there are some limitations which
must be observed.
• For U.S. installations only: The radios are required to comply with FCC Rules
and Regulations as Part 15 devices. As such, they have limited transmitter
power and therefore limited range.
• A receiver cannot respond to more than one transmitted signal at a time
and may be blocked by radio signals that occur on or near their operating
frequencies, regardless of code settings.
• Changes or modifi cations to the device may void FCC compliance.
• Infrequently used radio links should be tested regularly to protect against
undetected interference or fault.
• A general knowledge of radio and its vagar ies should be gained prior
to acting as a wholesale distributor or dealer, and these facts should be
communicated to the ultimate users.
