Product Overview
The Listen Technologies LA-141 ListenIR Expansion Radiator is part of the most advanced, lowest cost IR solution available. The LA-141 can be added to the LT-84 ListenIR Transmitter/Radiator Combo for additional coverage of up to 30,000 sq ft (2787 sq m) with LR-4200-IR/LR-5200-IR receivers or 7,500 sq ft (697 sq m) with LR-42/LR-44 receivers in single channel mode, when mounted within 100 ft. (30.48 m) of cable length from the LT-84. Up to four (4) Expansion Radiators (LA-141) can be daisy chained to an LT-84 system.
A single CAT-5e cable carries both power and signal to the Expansion Radiators (LA-141) making it a true one-cable connection. Placing additional Expansion Radiators (LA-141) in the same room increases the overall coverage area and enhances the freedom of movement within the room. The included mounting hardware allows the LA-141 to be easily mounted to the wall, ceiling or table.
