4.0 EMERGENCY OVERRIDES & PRIORITIES
4.1 PRIORITIES
There are 5 levels of priority in the A 4480.
Level 1
The
emergency microphone
is a hard wired microphone which connects to the 3 pin XLR connection as shown
in the full connection diagram. This has top priority and will override all other inputs. The gain of this microphone
is set by the screwdriver adjust controls on the front of the A 4480. A signal presence LED indicates signal being
received from the microphone.
Level 2
The
A 4481 paging console
(optional) has an emergency paging function which will override all other inputs
except the emergency microphone. See section 5.1 for details. The gain of this microphone is set by the screw
driver adjust controls on the front of the A 4480. A signal presence LED indicates signal being received from the
microphone.
The
priority input
operates on the same priority level as the A 4481 paging consoles. (See section 5.2 for details)
The priority input and the paging consoles work on a First In Best Dressed basis.
Level 3
The
alert/evacuation tones
provide the next level of priority and will override all inputs except the emergency
paging microphone, the paging consoles (if fitted) when used in emergency paging mode and the priority input.
Level 4
The A 4481 paging console when operating in standard paging mode has the next level or priority and will over
ride all local zone inputs and line inputs.
Level 5
The A 4478 local input wallplate (optional) will override audio routed to the same zone the A 4478 is connected
to.
Input audio sources 1-8 have the lowest priority and will not override anything.
4.2 PRIORITY INPUT
The priority input can be triggered via a closing contact or a vox operated audio input. This makes it useful for applications
such as telephone paging or the playing of the ODE in RSL clubs when used in conjunction with a timer.
