Audioaccess W.H.E.N. AVR21EN - WPS21 Features

Mounting Screw Holes: Eight slots, four on each mounting
flange, used for attaching the WPS21 to a structured wiring panel
or wall surface. These holes are punched to fit the hole patterns on
Channel Vision C-0128E and Leviton 47605-28W structured wiring
panels. (These specific models will each accept three hubs.)
WPS Status Panel: One adhesive lexan label fits into the
recess on a WPS21 top panel to indicate power, hub connection
and keypad connections. Three different labels provide proper
identification of keypad/zone configuration by hub (i.e., Hub 1,
keypads/Zones 1–7; Hub 2, keypads/Zones 8–14; Hub 3, keypads/
Zones 15–20) for confirmation of connections and activity during
installation and troubleshooting.
Power Indicator: One red LED lights to indicate that the
WPS21 has AC power.
Keypad Power Status Indicators: Seven green LEDs light
to indicate active
KP21 Power Terminals . The LED will turn
off if the KP terminal fuse has blown.
A/V Hub Power Status Indicators: One green LED lights to
indicate an active AVH21
A/V Hub Power Terminal . The LED
will turn off if the KP terminal fuse has blown.
KP21 Keypad Power Fuses: Seven four-amp fuses, one for
each keypad, protect the keypad power line from spikes and the
WPS21 from overloading.
AVH21 A/V Hub Fuse: One four-amp fuse, protects the
AHV21 power line from spikes and the WPS21 from overloading.
WPS21 Mounting Flange: Chassis metal extensions on either
side of the WPS21 used for vertical installation to structured wiring
panels or wall surfaces using mounting holes.
KP21 Power Terminals: Seven four-position plug-in terminals
connect to
Power +/– Terminals on individual KP21 keypads
to provide DC voltage to the keypads.
AVH21 A/V Hub Power Terminal: One four-position plug-in
terminal connects to
Power In on an AVH21 A/V Hub to
provide DC voltage to the A/V hub and connected KP21 keypads.
AC Power Cord Jack: Connect the AC power cord to this jack
when the installation is complete. To ensure safe operation, use
only the power cord supplied with the unit. If a replacement is
required, it must be of the same type and capacity.
