announces important system information through the Console’s  
speaker. The volume control adjusts the voice level.

The VB-4 features 2-way audio (manual and full duplex) and audio  
listen-only capabilities for Central Station monitoring. The small  
microphone supplied fits into the Console’s case. The module’s  
high-gain amplifier 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.

Linear radio controls provide a reliable communications link and fill  
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 modifications to the device may void FCC  
compliance.  
Infrequently usedradio linksshould betestedregularlytoprotect  
against undetected interference or fault.  
A general knowledge of radio and its vagaries should be gained  
prior to acting as a wholesale distributor or dealer, and these  
facts should be communicated to the ultimate users.
