Z-LA-141 Expansion Radiators

The Z-LA-141 infrared expansion radiator is part of the most advanced low cost infrared solution.

The Z-LA-141 infrared expansion radiator is part of the most advanced low cost infrared solution.

The Z-LA-141 can be combined with the Z-LT-84 Transmitter/Radiator Combo for additional coverage of up to 30,000 ft² (2787 m²) with Z-LR-4200-IR/Z-LR-5200-IR receivers or 7,500 ft² (697 m²) with Z-LR-42/Z-LR-44 receivers in single channel mode, when mounted within 100 ft. (30.48 m) of cable length from the Z-LT-84. Up to four (4) Expansion Radiators (Z-LA-141) can be daisy chained to an Z-LT-84 system.

A single CAT-5e cable carries both power and signal to the Expansion Radiators (Z-LA-141) making it a true one-cable connection. Placing additional Expansion Radiators (Z-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 Z-LA-141 to be easily mounted to the wall, ceiling or table.
