General Purpose Inputs/Outputs - Bose ControlSpace AMS8 Safety Instructions & Installation Manual

3.9 General Purpose Inputs/Outputs (GPIO)
ControlSpace AMS-8 includes one GPIO/RS232 card (see also chapter 3.2).
™
Up to 40 GPIO contacts (8 per rack, max 5 rack frames in total) can be used to trigger up to 40 messages,
up to 40 room combine presets or the Room Standby function ('mute') on different or all outputs.
The contacts are triggered by applying 24VDC between the specific contact and the common ground pin.
NOTE: A 'Pulse' contact will play a message once. A 'Hold' contact will play and repeat a message until
the contact is released. Use a hold contact to activate room combining or standby mode (release this
contact to de-activate these two functions)
Characteristics
• 8 isolated inputs
• 1 isolated output
• Inputs can be used for message routing, room combining or to put an output or group of outputs in
standby mode (outputs will return to default value when contact is released again)
• Open collector output is activated when one of the eight inputs is activated
