When used in conjunction with the AU-360 and AU-380 Series amplifier modules, the AU-386 Series speaker loop zone splitter provides an excellent way of designing Voice Evacuation and Paging systems of any size and level of complexity. Operation
The AU-386 Series speaker loop zone splitter provides the capability of splitting the audio output power from a single amplifier into four (4) speaker loop outputs. If additional speaker loops are required, AU-386 modules can be wired in series to expand the total number of speaker loops in multiples of four.
Control of zone selection is possible via manual control and/or by inputs from the Fire Alarm Control Panel (FACP). Automatic control allows for tones and/or messages to be broadcast to selected areas of a building, such as “Floor-above / Floor-below” in a high rise occupancy. There are two input options available. Please see Operation for details.
Audio will be broadcast into a selected zone only when that zone has been enabled. The red “Active” LED for any zone(s) enabled will be on. The yellow “Fault” LED for a zone indicates either an open circuit or a short circuit is present on the speaker loop. The “Common Fault” LED will activate when a fault condition is detected on any speaker loop or an internal fault occurs within the AU-386. If a speaker loop is shorted, the auto-reset fuse will open and isolate that zone for the duration of the short circuit. Features
Speaker loop outputs can be selected by utilizing one of two options. Providing a +24 VDC input to a zone select terminal on the AU-386 module will activate that zone. The selection of speaker loops on the AU-386-2 modules is accomplished by the closure of an external normally open (N.O.) dry contact or an open collector “pull down” circuit.
