Door 1 Dry-Contact Latching Trigger Output:
One two-posi-
tion plug-in terminal connects to a remote door lock that requires
a latching dry-contact closure to activate. (This type of door lock
system would provide its own power to activate when the circuit is
closed; therefore, 0 voltage, or a “dry closure,” is used.)
Door 1 12V/24V DC Selector:
One two-position switch sets
the output voltage for the
Door 1 12V/24V DC Latching Trigger
Output
. Set to 12V for door locks requiring up to 12 volts; set
to 24V for door locks requiring between 12 and 24 volts.
Door 2 12V/24V DC Latching Trigger Output:
One two-posi-
tion plug-in terminal connects to a voltage-activated door lock.
Selectable 12V or 24V DC output allows remote control of voltage-
activated door locks.
Door 2 Dry-Contact Latching Trigger Output:
One two-posi-
tion plug-in terminal connects to a remote door lock that requires
a latching dry-contact closure to activate. (This type of door lock
system would provide its own power to activate when the circuit is
closed; therefore, 0 voltage, or a “dry closure,” is used.)
Door 2 12V/24V DC Selector:
One two-position switch sets
the output voltage for the
Door 2 12V/24V DC Latching Trigger
Output
. Set to 12V for door locks requiring up to 12 volts; set
to 24V for door locks requiring between 12 and 24 volts.
Uplink Terminal: One RJ45 jack connects to the Multiroom
Link
on the AVR21EN rear panel. This link allows two-way com-
munication of zone/system control from connected KP21 keypads.
Digital audio data for common-source audio distribution is also
provided via this connection. The Uplink terminal connects to the
Expansion/AUX KP Terminal on the previous sequential
AVH21 to loop control and digital audio data when using multiple
AVH21s in expanded systems (i.e.,
AVH21 Hub 1 Expansion/AUX KP
Terminal
connects to the AVH21 Hub 2 Uplink Terminal ).
Source Video Bypass Outputs: Six female F-type terminals
output the composite video signals connected to the
AVH21
Source Video Inputs
for distribution of the six common-
source components connected to the AVR21EN to additional
AVH21 hubs, for additional zones in expanded systems.
Keypad/Zone Video Outputs: Six female F-type terminals
output common-source composite video to the video displays in
the individual zones as selected by the zone keypads or remotes.
Camera Video Bypass Outputs: Seven female F-type
terminals output composite video from security or zone monitor
cameras connected to the
AVH21 Camera Video Inputs for
distribution to additional AVH21 hubs, for additional zones in
expanded systems.
AVH21 Mounting Flange: Chassis metal extensions on either
side of the AVH21 used for vertical installation to structured wiring
panel or wall surfaces using mounting holes.
KP21 Keypad Terminals: Seven RJ45 jacks connect to the
individual KP21 keypads in each zone. These terminals provide
two-way communication between the keypads and AVH21 hubs;
and AVR21EN multiroom system controller for source/zone/system
control. They also output digital audio data to the keypad amplifiers
for audio from common-source components as selected by the
zone keypads or remotes.
Expansion/Auxiliary Keypad Terminal: One RJ45 jack
connects to the
Uplink Terminal on the next sequential
AVH21 hub to loop data for zone/system control and digital audio
distribution when using multiple AVH21s for additional zones in
expanded systems.
Camera Video Inputs: Seven female F-type terminals
connect to the composite video outputs on security or zone moni-
tor cameras. The primary AVH21 connects directly to the camera
outputs while the secondary hubs connect to the
Camera Video
Bypass Outputs
on the previous hub in the distribution chain
(i.e.,
AVH21 Hub 1 Camera Video Bypass Outputs connect
to
AVH21 Hub 2 Camera Video Inputs ).
Source Video Inputs: Six female F-type terminals connect to
the
Video Source Out Terminals on the AVR21EN rear panel
for input of common-source composite video feeds. The primary
AVH21 connects directly to the AVR21EN outputs while the secondary
hubs connect to the
Source Video Bypass Outputs on the
previous hub in the distribution chain (i.e.,
AVH21 Hub 1 Source
Video Bypass Outputs
connect to AVH21 Hub 2 Source
Video Inputs
). These inputs allow selection of any available
common-source video signal to be selected by a zone keypad or
remote.
Power In: One four position plug-in terminal for connection to
WPS21 power supply hub
AVH21 A/V Hub Power Terminal
.
Door 1 12V/24V DC Latching Trigger Output:
One two-posi-
tion plug-in terminal connects to a voltage-activated door lock.
Selectable 12V or 24V DC output allows remote control of voltage-
activated door locks.
