2.0 DESCRIPTION
Spectra® (Version 3.0) domes are capable of the following:
• 360° pan rotation • preset positioning
• +2 to -92° tilt • variable speed
The in-ceiling models can be installed in hard ceilings or standard 2' x 2' (61 cm x
61 cm) suspended ceilings. These models are for indoor installation only .
The pendant models can be installed indoors or outdoors. The outdoor models
include a sun shield and heater. The heater allows operation in temperatures down
to -60°F (-51°C).
All models include a high-resolution color or monochrome (black and white) camera with a 12X optical, 8X electronic zoom lens for a total zoom ratio of 96X.
An integral receiver has a switch to select the type of control. The receiver supports
Coaxitron
The dome drive quickly disconnects from the back box for easy servicing or moving.
The Spectra

3.0 INSTALLATION FOR IN-CEILING MODELS
To install the dome proceed through the steps in this section, beginning with Section 3.1, “Ceiling and Back Box Preparation.”
3.1 CEILING AND BACK BOX PREPARATION
3.1.1 Hard Ceiling
NOTE:
Use the SCA1 (structural
ceiling adapter) if additional support
is required.
CAUTION:
Be careful
not to cut outside of the
line. If you do, you may not
be able to install the back
box. Also, the trim ring
may not cover the hole.
1. Locate the center point where you want to drill a hole in the ceiling.
2. Drill a hole in the ceiling using a 3/32-inch drill bit.
3. Remove the compass tool from the parts bag that came with the back box
(refer to Figure 4). Press the stud of the compass tool into the hole in the
ceiling. Insert a pencil in the hole in the other end of the compass and mark a
circle on the ceiling.
4. Carefully cut the circle out of the ceiling.
5. Remove the conduit fitting, lock nut, and safety chain bracket from the parts
bag and attach them to the back box as shown in Figure 5.
Proceed to Section 3.2, WIRING.
ATTACH SAFETY CHAIN HERE
Figure 4. Compass Tool Figure 5. Conduit Fitting Installation
14 Pelco Manual C1456M-D (10/98)
3.1.2 Suspended Ceiling
CAUTION:
The ceiling
tile must be capable of
supporting 16 pounds
(7.3 kg) of weight. If the
ceiling tile will not support
this weight, order the
SD5-P metal panel.
CAUTION:
Be careful
not to cut outside of the
line. If you do, you may not
be able to install the back
box. Also, the trim ring
may not cover the hole.
1. Remove the ceiling tile from the ceiling.
2. Locate the center point to drill a hole in the tile.
3. Drill a hole in the ceiling tile using a 3/32-inch drill bit.
4. Remove the compass tool from the parts bag that came with the back box
(refer to Figure 4). Press the stud of the compass tool into the hole in the
ceiling. Insert a pencil in the hole in the other end of the compass and mark a
circle on the ceiling.
5. Carefully cut the circle out of the ceiling tile.
6. Remove the conduit fitting, lock nut, and safety chain bracket from the parts
bag and attach them to the back box as shown in Figure 5.
7. Refer to Figure 6. Compress the spring clips on the back box with your hands
and push the back box through the hole in the ceiling tile. The spring clips will
spring out when they clear the ceiling tile.
8. Refer to Figure 7. Tighten the screws until the spring clips hold the back box
firmly to the ceiling tile. Y ou will hear a clicking noise when the screws are tight.
Do not install the ceiling tile in the ceiling yet.
Proceed to Section 3.2, WIRING.

3.2 WIRING
Bring wiring to the back box opening in the ceiling. Do not attach the wiring to the
back box. Y ou will do that later .
Refer to Figure 8 for the wiring diagram.
Wiring is required for power, earth ground, and video.
Refer to Table A for the type of video coaxial cable to use.
Input power for the dome is 24 VAC only. Power consumption is 25 vA per dome for
indoor models and 90 vA for outdoor models. Refer to Table B to determine the size
of wire to use.
Use a 24 VAC transformer with the following minimum vA:
NOTE:
The dome will stop operating if the voltage at the dome
drops below 18 VAC. It will turn
back on when the voltage exceeds
18 VAC.
30 vA per dome For indoor models (without heater)
100 vA per dome For outdoor models (with heater)
Refer to Figure 10 for wiring multiple domes from the same transformer.
If you are using a Coaxitron
®
controller, the control signals to operate the dome
drive will be transmitted over the video coax. The RS-422 control lines are not used.
If you are not using a Coaxitron® controller, use the RS-422 control lines. Use 22-
gauge wire. The distance will be the same as the video coax.
Optional wiring may be provided for alarm inputs (maximum of seven), relay output,
and auxiliary output.
Proceed to Section 3.3, BACK BOX INSTALLATION.

3.3 BACK BOX INSTALLATION
OPTIONAL PROCEDURE:
If
you prefer, you may make the wiring connections inside the back box
before installing the back box in the
ceiling.
To do this, loosen the thumbscrew
inside the back box and open the
hinged door (refer to Figure 9).
Bring the wiring into the back box
through the conduit fitting. Follow
the steps in Section 3.4, “Back Box
Connections,” and then return to
this section.
CAUTION:
The ceiling
must be capable of supporting 16 pounds (7.3 kg)
of weight. If the ceiling will
not support this weight,
provide additional reinforcement. Also, a suitable safety chain must be
attached to the back box
to support up to 16
pounds (7.3 kg) in the
event of a ceiling failure.
1. Suspended Ceiling Only (for hard ceiling, go to step 2) – Install the ceiling
tile with the back box. Attach a T-rail clip on each side of the ceiling tile as
shown in Figure 7.
The clips for the ceiling tile are supplied with the back box. Attach the clip to
the T -rail. Fasten the L-bracket to the clip with the supplied screw, lock washer
and nut.
2. Install a safety chain or cable (not supplied) that will support up to 16 pounds
(7.3 kg). Fasten one end to a support structure in the ceiling. Fasten the other
end to the safety chain bracket (refer to Figure 5) to prevent the back box from
falling.
3. Refer to Figure 9. Loosen the thumbscrew inside the back box and open the
hinged door.
4. Bring the wiring into the back box through the conduit fitting. If the wiring is
inside flexible conduit, connect the conduit to the fitting on the back box.
5. Hard Ceiling Only - Refer to Figure 6. Compress the spring clips on the back
box with your hands and push the back box through the hole in the ceiling. The
spring clips will spring out when they clear the ceiling. Refer to Figure 7. Tighten
the screws until the spring clips hold the back box firmly to the ceiling. Y ou will
hear a clicking noise when the screws are tight.
Proceed to Section 3.4, BACK BOX CONNECTIONS.
