The intelligent video mixer(s) shall be Alpha Communications® / S.T.R.™ QwikBUS™ model MXV333, or approved equal. The MXV333 shall be built into a rugged high impact ABS plastic case, and shall be used with the associated SP333 intelligent controller (and associated SNT333 power supply) for up to 40 QwikBUS™ video stations (8-10 per line maximum). Contractor shall furnish the proper number of SP333 and SNT333 units (and related components), depending upon system capacity.
Low voltage wiring shall be used and positive screw terminals shall be provided for installation wiring. The MXV333 shall be mountable right to the surface of the wall or in a customer-supplied junction box cabinet.
Contractor shall observe all local and national electrical and building codes.
The Alpha Communications® / S.T.R.™ MXV333 intelligent mixer is used only with the QwikBUS™ series video-intercom systems for systems with more than 32 addressable QwikBUS™ video stations. The MXV333 provides the intelligent circuitry needed to install multiples of up to 40 QwikBUS™ video stations, allowing systems with very large system capacities.
Each MXV333 gets its power from its associated SP333 intelligent controller and corresponding SNT333 power supply. All MXV333 field connections are positive screw terminal type. Each MXV333 requires the SP333 and SNT333, and C333-2 connecting cable assembly.
