Hi all, I'm new here and need some help. I've taken "IQ school" but a long time ago, and this is my first real-world application of the IQ product. I've got a 6 floor office building, with an existing (1975ish vintage) Bogen 70V paging system. There are multiple inputs routed to a TOA mixer, with a global "all call" page or music output to all zones/floors. It's primarily a background music & emergency page system, zone paging is not possible nor needed. All of the existing gear is to be scrapped, save the TOA mixer, and possibly the zone monitor panel/speaker (rack mounted). They are to be replaced with (as recommended by our rep.): 3) CTS-600 amplifiers (each channel handling a floor of the building) 1) CTS-600 amp (a totally redundant backup amplifier - customer required) 4) PipLite modules What the customer would like is: Indicator panel (LED or similar) of amplifier status. Automatic switching/routing of output (s ((maximum of 2)) to the redundant amplifier in the event of primary amplifier failure. Audible alert (buzzer with silence button) of amp/channel failure. All of these features are currently in place, even with the system's advanced age, using electro-mechanical switching via relays and lamps. Can I do it with the PipLite's and the CTS-600's?? Or, do we need to delve further?
