Facility Terminals
dc Output
The two top terminals of the four terminals labelled FACILITY (see Rear Panel No.15 on
Page 8 and diagram below) provide a 24V current protected output, which can be used to
supply external devices (such as relays or line pre-amplifiers) to a maximum of 250mA.
Restoration
The two bottom terminals of the four terminals labelled FACILITY provide volume
restoration. When a closure of any of the priority terminals is detected, the terminal
marked ‘Restoration’ will conduct to ground (open collector). This can be used to drive
volume restoration relays in volume controls or to drive ‘busy’ lamps in multiple
microphone systems.
