Installation
Description, Specifications, and Installation Manual
You can use several methods to activate the UVRI-B. Use the manual activation buttons
and a hand-held microphone to activate the UVRI-B locally. Use landline control through
normally open contact switches. Make connections directly to the controller terminal
block. Activate the UVRI-B remotely through the optional radio receiver or an external
600 ohm audio source. Plan how the UVRI-B will be connected to the antenna system
wired or wireless communications network. If you are using radio control, consider RF
coverage and antenna placement when selecting a suitable location.
