Chapter II Installation
This installation should be made by a qualified service person and
should conform to all local codes.
Note:
Take V1691 as an example to show unit installation in this
chapter. Unless specially noted, the descriptions illustrated for
V1691 apply to all V1691 series receiver/drivers.
2.1 Mounting
V1691 receiver/driver is used both indoor and outdoor, and it may
be surface mounted in any orientation. To minimize voltage drop in
the wiring, mount the receiver/driver near the cameras to be
controlled.
The dimensions of the receiver/driver are:
W305mm
×
H83mm
×
D202mm (outdoor) or W290mm
×
H95mm
×
D185mm (indoor),
without the mounting ears.
z
Select the suitable nuts when making surface mount.
z
For wood studs mount, use lag bolts (with a drilled pilot hole) or
wood screws, which penetrate the wood for at least one inch.
z
For concrete surface mount, use lead or plastic anchor expansion
bolts with a minimum pull-out rating of 10 pounds.
z
For steel surface mount, drill four bolt clearance holes and use
bolts with lockwashers and nuts.
z
For drywall (gypsum) wallboard mount, use toggle bolts. Drywall
thickness must be at least 0.38-inch.

Chapter III System Connections and Setup
3.1 System Connections
Note:
Take V1691 as an example to show system connections and
setup in this chapter. Unless specially noted, the descriptions
illustrated for V1691 apply to all V1691 series receiver/drivers.
3.1.1 Code Source to V1691 Series receiver/drivers
V1691 control line connector (J202) is a 3-position terminal, labeled
“B R+”, “W R-”, and “S G” on the side panel of the unit, and a
mating 3-position screw-terminal plug is supplied.
Note:
The code source could be INFINOVA series matrix
switching system, V2116 system keyboard or V2411 code
distributor.
Wiring:
Use 18 AWG, shielded, 2-wire cable, Belden 8760 or
equivalent (for plenum, Belden 88760). The maximum connection
distance is 5000 ft. Insert the appropriate signal wires into the slots
of the mating connector and tighten the hold down screws. When
all wires have been connected, insert the mating connector into the
code connectors on V1691.
1.
Check the power supply cable to make sure power is off;
2.
Insert and screw down the Black Code wire into the screw
terminal marked B R+;
3.
Insert and screw down the White Code wire into the screw
terminal marked W R-;
4.
Insert and screw down the Shield wire into the screw terminal
marked S G.
V1691 receiver/driver is designed for a “Star” connection to a code
distribution unit. A 120-ohm terminating resistor is installed on the
Receiver code input line (See figure 3-1, 3-2).
