Each OP is equipped with an integrated infrared eye on the bottom of the OP enclosure
allowing remote usage and connectivity. Using the Spectra i.Net hand-held remote control, point
the remote to the bottom of the OP enclosure for IR line of sight control. Adjustments to the OP may
be made from the remote control for masking volume and masking contour or paging volume or
music volume by either single audio channel or entire OP.
Each OP is also equipped with an IR port on the side of the OP enclosure. This port allows an IR
keypad to be installed via plenum rated CAT 5e wire and an RJ45 connector from the OP located in
the ceiling plenum to the space below the plenum, in a location along a wall, similar to that of a
normal wall switch. This setup allows for IR keypad use without having to remove a ceiling tile.
The IR Hub is an additional component that allows for more than one keypad to be installed in an OP
IR port giving a single OP audio channel specific control to a respective keypad. Up to four keypads
may be installed in each hub allowing four keypads to be installed per each OP.
