Part I – SB3-1/SB3-2 and
SB2800 Series Enclosures

PREFACE: There are two parts to this manual.

Part I covers the SB3-1, SB3-2, and SB2800 Se­ries Dome Enclosures. Part II covers the
PT2801000 Series pan/tilt assemblies which are
used in the SB2800 Series Dome Enclosures.
Please refer to the applicable sections of this
manual when installing your system.

1–2.0 SCOPE

The information contained within this manual covers
the installation and operation of the SB3-1/SB3-2 and
SB2800 Series Discreet Surveillance Enclosures.

1–3.0 DESCRIPTION

1–4.0 INSTALLATION

1–4.1 UNPACKING INSTRUCTIONS

Save the shipping carton and plastic packing, in case
the unit has to be returned for credit or repair.

1–4.2 WIRING INSTRUCTIONS

SB2800 Series system packages include pan/tilt assem­blies which are pre-wired for all control functions –
pan/tilt, motorized zoom lens, camera power (24VAC)
and video. All connections are made at the input con­nector, eliminating the need for wiring harnesses made
in the field. Wire the control cable per Section 2-2.0,
Part 2 and the referenced diagrams, or use factory as­sembled pretested cables C1906, C1906/PP, C1925, or
C9125/PP.

The SB3-1/SB3-2 and SB2800 series are low profile
discreet enclosures designed for ease of installation, re­location and service in standard 2' x 2' or 2' x 4' false
ceiling grids. Available with a black opaque or mirrored
lower dome, these domes combine concealed 355° sur­veillance (360° on SL models) with distortion-free view­ing. The lower dome effectively conceals the camera
while providing an inconspicuous viewing window with
a light attenuation factor of one (1) f-stop for the black
opaque dome and 2 f-stop light loss for the mirrored
dome. There is, of course, no light attenuation factor
for the SB2801 clear dome.

The dome and camera assembly rotate at a speed of 10
degrees/second on a balanced roller system for com­plete 355°/360° surveillance coverage. The back box is
constructed of aluminum to meet fire code requirements
for installation in open plenum ceilings. The SB3-1/
SB3-2 and SB2800 will accept Pelco lenses up to 110
mm, increasing the flexibility of the system design and
application.

To simplify installation even further, Pelco offers sys­tem packages with factory installed standard compo­nents from its regular product line. This dramatically
reduces installation time and cost and assures the con­tinued availability of replacement parts.

1–4.3 INSTALLATION INSTRUCTIONS

Your dome is supplied in two ways; as a passive dome
(SB3-1/SB3-2) for use as a dummy dome or with a fixed
camera (utilizing the CM3000 mount), or with a fac­tory installed pan/tilt assembly (SB2800 series mod­els). To install the dome or dome system, perform the
following steps (see Figure 1-2):

1. Handle the lower dome with care so as not to
scratch or get fingerprints on the viewing window.

2. Mount the back box directly into a 2' x 2' false
ceiling grid and make certain that the assembly sits
flat on the grid.

NOTE: When installing the enclosure in a 2' x 4'
ceiling, cut the ceiling tile in half and install an
additional “T” rail for support. If further support is
required, install an eyebolt in the plywood base of
the back box and run a guy wire to secure the sur­face.

3. Mount the camera/lens onto the optional fixed
mount (CM3000) or pan/tilt assembly with the
camera/lens centered on the tilt table. Hook up cam­era power, video and lens. Extend the lens to the
maximum focal length and operate the pan/tilt to
verify that there are no obstructions within the back
box.

PELCO Manual C426M-F (2/98)2

4. Attach the safety chain to the lower dome and make
certain that the chain does not interfere with proper
seating of the drive tab. (See Figure 1-1.)

CAUTION: Dome will shatter if dropped. Al­ways operate with safety chain attached Do not
rotate pan/tilt by hand. Rotate by controller only.

5. Install the lower dome with viewing slot to the right
of the camera/lens with the lens pointed towards
you. Insert the rim of the dome into two of the roll­ers. Align the drive tab with the slot in the drive
arm bracket. Press the dome against the rollers and
gently deflect the dome until you are able to insert
the rim into the final rollers. (See Figure 1-1.)

6. Operate pan/tilt to verify that there are no obstruc­tions within the back box or dome.

1–4.4 LIMIT/STOP ADJUSTMENTS

Refer to Section 2-2.3, Part 2 of this manual for limit
adjustments.

1–5.0 CARE AND MAINTENANCE

isopropyl alcohol diluted with water. Hold the dome
with its opening facing downward and wipe the
interior of the dome with the wet end of the wick.
Use a circular motion, starting from the outside
and spiraling into the center. Use a new wick for
each two passes over the dome.

Clean the acrylic lower dome as necessary to maintain
a clear picture. Be careful not to scratch the surfaces of
the dome.

Exterior Surface - Clean the dome's exterior surface
with a nonabrasive cleaning cloth and cleaning agent
that is safe for acrylic plastic. Either liquid or spray
cleaner/wax suitable for fine furniture is acceptable.

Interior Surface (Except Chrome) - Clean the same
as the exterior surface.

Interior Surface (Chrome) - The inside surface of a
chrome dome is easily scratched. Use the following pre­cautions to maintain the dome's surface.

a. Always handle the dome from the outside of its

circular flange.

b. Never touch the coated inside surface. The acid in

your fingerprints will eventually etch the coating
if the fingerprints are not carefully removed ac­cording to the recommended cleaning procedure
in item “e.”

c. If dust or other contaminants accumulate on the

dome's interior, remove the debris with compressed
air. Compressed air cans are available from photo­graphic equipment or electronic supply dealers.

d. If heavy residue accumulates and cannot be re-

moved with air pressure, rinse with water and im­mediately dry with air pressure so that water spots
will not remain. Avoid wiping the coated surface
with direct hand pressure - it will easily abrade un­less extreme care is taken. Once scratched, the
dome cannot be recoated.

e. If internal wiping is necessary, avoid hand rubbing.

Instead, make a wick as follows:

Pan/Tilt Assemblies

2–1.0 DESCRIPTION

Lens Functions:

22 Awg 600 ft (182.88 m)
20 Awg 1,000 ft (304.80 m)
18 Awg 1,500 ft (457.20 m)

The pan/tilt assembly is a “mini” light duty pan/tilt for
loads up to 15 lbs and is factory pre-wired for all con­trol functions (pan and tilt, motorized zoom lens, cam­era power (24 VAC), and video). All connections are
made at the input connector, eliminating the need for
wiring harnesses. This greatly reduces installation time,
while increasing reliability and serviceability.

2–2.0 INSTALLATION

In order to insure proper wiring and system operation
of all components, it is highly recommended that the
pan/tilt and the associated control equipment be tested
in your facility before field installation is attempted.
Wire the control cable in accordance with Figures 2-1
through 2-3.

2-2.1 CONDUCTOR AND CABLE

REQUIREMENTS

Conductors

The following are the conductor requirements:

SB2800/SB2801/
SB2800-SL Pan/Tilt (5 plus ground),

Lens (4), Camera AC (2)

SB2800/PP Pan/Tilt (9 plus ground),

Lens (8), Camera AC (2)

SB2800-SL/PP Pan/Tilt (10 plus ground,

Lens (8), Camera AC (2)

Cable Distances – Hard Wire Controls

The following cables distances are for hard wire con­trols:

Pan/Tilt Functions:

5 Conductors 6 Conductors*

Camera Power

2 Conductors (24 VAC)

Consult the camera manufacturer or factory for trans­former power distances.

Cable Distances – Coaxitron

The following cable distances are for Coaxitron con­trols:
Up to a maximum of 750 feet on a single coax (RG59/
U) from the receiver to the transmitter.

NOTE: To extend the distance to 3,000 feet on
RG59/U coax, use the Pelco EA2000 Half Duplex
Equalizing Amplifier.

2–2.2 WIRING

Cable distances should not exceed the distances speci­fied in Section 2-2.1, Conductor and Cable Require­ments. The following are some recommended common
installation practices.

1. Always use jacketed stranded multi-conductor in­terconnecting cable between the control and the
pan/tilt unit, with additional conductors than
needed for future servicing and or additions.

2. Always use color-coded conductors for ease of
wiring and to identify functions at a later date.

3. Keep a wiring diagram with the system for later
use and reference.

When the pan/tilt assembly is mounted in the inverted
position, the LEFT/RIGHT and UP/DOWN functions
are reversed during operation. To correct this problem,
reverse the LEFT/RIGHT functions in the control cable
(pins 3 and 7) at the pan/tilt or control and the UP/
DOWN functions (pins 5 and 6) at the pan/tilt or con­trol.

20 Awg 110 ft (33.53 m) 210 ft (64.01 m)
18 Awg 180 ft (54.86 m) 330 ft (100.58 m)
16 Awg 290 ft (88.39 m) 530 ft (161.54 m)

PELCO Manual C426M-F (2/98)

NOTE: If you have purchased the C1906, C1906/
PP, C1925 or C1925/PP factory pre-wired cables,
correction for reversal of these functions has al­ready been made in the cable. You do not need to
reverse the pins for inverted mounting if you use
the above mentioned cables with your pan/tilt.

2-2.3 LIMIT/STOP ADJUSTMENTS

WARNING: Do not operate pan/tilt without limit

stops. Do not remove or reposition fixed limit stop
on the PT 2801000ASSY or PT2801002ASSY.

DAMAGE WILL OCCUR.

NOTE: The PT2801001ASSY and PT2801003ASSY
are not equipped with pan limit stops. (Disregard
steps 1-5 below).

6. Remove the cover plate from the left side of the
tilt table. Loosen the limit stop screws and tilt the
table, using the joystick, to the desired "up” posi­tion.

7. Move the “up” limit stop until it touches the tilt
limit switch actuator and “clicks”. Lock the stop
in place.

8. Tilt the table to the desired “down” position and
set the stop in the same manner.

To set limit stops, perform the following steps
(refer to Figure 2-4).

1. Loosen the pan limit stops.

2. Turn the control unit on. Pan the unit to the right
until the desired right pan limit is reached.

3. Move the right pan limit stop until it touches the
pan limit switch actuator. Move the stop a slight
distance further against the actuator until it “clicks”,
indicating opening of the limit switch. Lock the
stop in place.

4. Pan the unit to the desired “left” position. Adjust
the left pan limit stop as described in Step 3.

5. Pan left and right to both limit stops and check for
exact positioning. Tighten both stops securely.

9. Tilt the table up and down and check for exact po­sitioning. Tighten both stops securely. Replace the
cover plate.

After the unit has been tested and stops aligned, turn
off the control and disconnect the AC cord from the
outlet. Remove the multiconductor cable from both the
pan/tilt and control unit. This cable can then be used
for installation by cutting the test cable and splicing
the ends onto the installation cable at the job site. Splice
the ends, color-to-color, onto the cable in the field, us­ing the terminal blocks at each end.

NOTE: When wiring a system it is recommended
that the multiconductor cable have extra conduc­tors for future use.

2–3.0 OPERATIONAL TEST

2–3.1 CONTROL

Connect the cable assembly between the pan/tilt and
the control unit. Plug the control unit into a 120 VAC
outlet and switch the unit on.

Figure 2-4 Limit Stops

PELCO Manual C426M-F (2/98)

Move the joystick to the UP position. Observing the
“Front” label on the pan/tilt, the front of the tilt table
should move up. Move the joystick to the DOWN posi­tion, and the front of the tilt table should move down.
Releasing the joystick should allow it to return to cen­ter and the tilt table should immediately stop moving.

Move the joystick to the LEFT position and the com­plete top assembly should rotate counterclockwise.
With the joystick moved to the RIGHT position, the
unit will rotate clockwise.

Both the pan and tilt motors are protected from me­chanical over-travel by electrical limits which stop the
motors.

2–3.2 AUTO/RANDOM SCAN OPERATION

2–4.2 SERVICE TIPS

The PT2801000 will function in the Auto/Random
mode with the addition of the appropriate Pelco con­trol system. The PT2801000 has no additional limit
switches or relays for auto scan operation and is, there­fore, only compatible with current sensing auto/random
type circuits employed in our control systems.

2–4.0 MAINTENANCE

2–4.1 RECOMMENDED EQUIPMENT

AND TOOLS

1. Voltmeter or Ohmmeter

2. Allen Wrench Set

3. Wrench Set

4. Screw Driver, Flat Blade, Phillips Head

5. Pliers, Long Nose

Some common problems encountered with pan/tilt sys­tems include mis-wiring, overloading, and not using
the units for the correct application. Should a failure
occur, it is recommended that the following procedures
be used.

1. If the pan/tilt ceases to operate, turn the control
unit off and remove the AC cord from the outlet.

2. Check the fuse in the control unit using either a
voltmeter or ohmmeter. If open (blown), replace
with the proper recommended fuse.

3. Replace the AC cord in the outlet and turn the con­trol on. If the fuse continues to open (blow), turn
the unit off.

4. Check the control cable between the control unit
and pan/tilt for shorts, high resistance, or opens.

5. If the control cable is found to be good, replace the
connector to the control unit, leave the connector
off the pan/tilt, and replace the fuse.

6. Operate the control unit when it is disconnected
from the pan/tilt. If the fuse continues to “blow”
the fault is in the control. Refer to the appropriate
service manual for the control being used.

7. Check the wiring harness in the pan/tilt for shorts.

8. If the wiring harness is found to be good, then the
problem is internal to the unit; consult factory.
