Digital Zone Manager (PZA)
GLOBALCOM ® EN54-16 Digital Zone Manager (4 Zones)
The 5404DZM Digital Zone Manager provides processing and management of four (4) paging zones assigned from an IED 5400 Announcement Control System. It also provides line-level audio outputs to a paired four-channel amplifier unit. Digital signal processing (DSP) is provided on each of the four (4) output channels. This includes: input level controls, paging routing, automatic background music ducking, equalization (high-pass filters, low-pass filters, up to 40 milliseconds of delay, plus up to 7 parametric bands per amp channel). The IED's patented environmental analysis and control provides automatic level adjustment with two (2) sensor input channels per amperage channel.
The 5404DZM provides backup amplifier switching by switching up to four (4) speaker loads from a primary power amplifier to a backup when a fault is detected. It also contains built-in supervision that monitors each signal path and reports any faults to the 5400ACS.
The main unit requires one (1) rack unit (1.75") of vertical space in a 19" equipment rack/cabinet. All cooling is from front to back.
