Mircom's ingenious design of KV-Series lobby panels are inspired by the continuous demands of architects, engineers, contractors and building owners. Made from rugged aluminium alloy the KVSeries is built to withstand years of use and abuse. Vandal-resistant features include metal call buttons, a poke resistant speaker grill and unique locking mechanism. The metal buttons prevent vandals from melting them with cigarettes or lighters. A variety of panels for speaker or handset intercom systems makes it easy to assembly a lobby panel to fit in virtually all applications. Each panel has a varying number of call buttons and directory spaces to accommodate system sizes from two to fifty apartments. The modular construction of the K-Series panels makes it easy for distributors to stock and provide immediate delivery for their customers. For vandalism protection a 16 AWG sheet of metal covers each speaker. A staggered arrangement of the speaker grill provides puncture protection without muffling the sound transmission of the speaker.
