Audio Sound
Card
The Audio Sound Card provides speaker capability to Information Centers and Clients
processing units. It is a qualified, standard component and is pre-installed.
Warning All cards must be in the slots shown for proper Information Center operation.
Make certain that the speaker cable
cannot accidentally be pulled out because it
annunciates alarms. Use the Strain Relief Mechanism provided and, also, secure the cable
to another secured cable using strain relief loops and cinch cable ties. Reference Strain
Relief Kit # M3150-60019. See illustration below.
