Standards and Legislation

 

Univox® PLS-900 Up to 700m2 area coverage

The PLS-900 is designed to work in conditions with severe metallic influences too harsh for the PLS-700. It delivers an impressive 25Amps(78App) at 47Vpp, driven by a 500VA toroid transformer to provide standard compliant area coverage up to 1800m2 with the enviable, but essential clarity of sound for intelligibility that you expect from our products. Housed in a rugged, convection cooled housing, the robust short circuit proof electronics provide quiet, reliable operation backed by our 5 year warranty. As all PLS’s, the PLS-900 is designed for long lasting performance and simple installation.

Engineering Simplicity

 

Engineering Simplicity is a Univox tradition; the PLS range is no exception and has been designed to simplify the amplifier selection, loop design and installation processes. All amplifiers in the range are specified to operate with single and 2 turn loops using 2.5mm2 cable. By installing a twin core multi- strand cable, the installer does not need to calculate cable impedance and he always has the flexibility to modify the performance of the system by: Amplifier selection (defines the basic power available to the system) Connecting only one core - (standard connection method) Connecting 2 cores in parallel (is equivalent to using a 5mm2 cable halving the impedance) Connecting 2 cores in series (forms a 2 turn loop approximately doubling the impedance ) Connecting 2 amplifiers (doubles the power of the system) With this flexibility built in and assuming no fundamental laws of physics have been broken, the installer can be confident that the perimeter loop installation will perform to standard without spending hours on measurements and calculations. Other cable types can be used, consult our loop design guide for information.
