Controller and privacy sign layout

Options on how to control the system
It is important to understand how the system will be used and controlled to decide the location of the
controller and privacy signs.
The controller unit is self-contained and can be operated by the end-user directly from the front panel.
The set-up features are hidden from the end user to prevent accidental changes.
The signs indicate that the system is fully on only when lit steadily. They blink during ramping on and off
(the gentle increase or decrease of sound level).
Optionally the system can also be controlled via contact closure (such as by an automation control
system). In this case the controller should be placed out of the way, such as in a closet or IT closet, to
reduce any confusion about the active control point. The system also features a nominal 5V trigger out
for status confirmation to a control system.
An external contact closure can also be used to allow control from a remote switch such as a light switch
or single-pole, single-throw (SPST) low voltage switch.
In an operating scenario in which contact closure is used, emergency cutoff can only be achieved if the
low level is MUTE and CC ramp down time is 0.
Optionally the system may be installed similar to standard sound masking (which is normally on 24/7),
with the controller visible or hidden.
Placing the controller:
In a place easy to reach for occupants of the room, such as near light switches near the room
▪
entrance, or at a convenient place accessible during presentations.
Can be visible or hidden, but remember people may not know how or where to operate it if its
▪
completely out of sight.
Placing the privacy signs:
Two privacy signs are provided, one for the room occupants and the other for people outside the
▪
room. Typically one sign is mounted inside the conference room to alert the occupants to status
and the other is mounted outside conference room, adjacent to the main door.
Use of both signs is not required or both may be installed inside or outside the room. Coordinate
▪
with Owner.
