2Pelco Manual C467M-D (5/95)
2.0 SCOPE
The information contained within this manual covers
the SB19/SB1900 Series of Discreet Surveillance En-
closures.
3.0 DESCRIPTION
The SB19 is a low profile, hemisphere, discreet sur-
veillance dome for CCD type cameras designed for ease
of installation, relocation, and servicing in hard ceiling
applications or in a standard 2' x 2' or 2' x 4' suspended
ceiling grid.
The black opaque lower dome effectively conceals the
camera while providing an inconspicuous viewing win-
dow. The dome mounts directly to the pan/tilt (or fixed
camera mount), thus keeping the viewing window and
camera aligned.
To simplify installation even further, Pelco offers
system packages with factory installed standard com-
ponents from its regular product line. Options include
a 24 VAC pan/tilt with factory pre-wired feed-through
for all control functions (i.e., pan/tilt, motorized zoom
lens, camera power (24 VAC) and video), continuous
360° pan rotation, and a position feedback package for
presets.
The dome and camera assembly rotate at a speed of 24
degrees/second for complete 360 degree surveillance
coverage.
The back box is constructed of aluminum to meet most
fire code requirements for installation in open plenum
ceilings.
4.0 INSTALLATION
Save the shipping carton and plastic packaging in case
the unit must be returned for credit or repair.

4.2 WIRING INSTRUCTIONS
The SB1900 and SB1900-SL include a pan/tilt which
is pre-wired for all control functions (pan/tilt, motor-
ized zoom lens, camera power (24 VAC), and video).
All connections are made to the input terminal block in
the J-box on top of the back box, eliminating the need
for wiring harnesses made in the field. Wire the control
cable according to the wiring diagram in Figure 1.
