AD1273 DESCRIPTION AAAAAAAAAAAAAA Figure 1 - AD1273 CobraDome Indoor Surveillance Unit in Drop Ceiling DESCRIPTION ROUTINE MAINTENANCE The AD1273 CobraDome Indoor Surveillance unit is designed for applications requiring a precision, high-speed pan/tilt mechanism with a variety of options. The standard AD1273 CobraDome is shipped ready for either drop-ceiling or hard mounting. Optional kits are available for a) converting to a pendant mount, and for b) replacing the original ceiling tile with a 2 ft.
COMPONENT IDENTIFICATION AD1273 COMPONENT IDENTIFICATION CHASSIS HOUSING CHASSIS ASSEMBLY The CHASSIS HOUSING contains the major components of the AD1273 CobraDome. Also, all mounting hardware is attached to the CHASSIS HOUSING. The CHASSIS ASSEMBLY contains all the camera/lens hardware, the pan/tilt motors and gears, the on-board electronics, and the power supply. Aluminum Tile The Aluminum Tile is used in drop ceiling installations. In a 2’ x 2’ grid, it replaces the ceiling tile entirely.

SETUP AD1273 SETUP 8-Position DIP Switch This section describes the required settings for proper operation of the AD1273. Before installing the AD1273, determine the intended operating requirements and set the related switches accordingly. An 8-position DIP switch labeled S1 configures each dome to the particular type of hardware. The DIP switch is configured at the factory, and only needs to be verified prior to installation.

SETUP AD1273 Camera Number Assignment Setting Camera Number Thumbwheel Switches For individual control of camera pan/tilt functions by a matrix switching system, an individual camera number must be assigned to each AD1273 unit. Two thumbwheel switches, located on the printed circuit board, identify the camera number for each AD1273 (see Figure 4).

SETUP AD1273 Dome Configurations Daisy Chain Configuration When using the AD1273 with other domes in a security system, determine the type of configuration that best suits the particular application. A daisy chain configuration triples the number of AD1273 units wired to each outlet port of a data distribution unit (see Figure 6). A maximum of three AD1273 domes may be daisy chained on a single data line.
AD1273 SETUP Jumper Removal 1) Disconnect all data, video, and power connections from the dome. To remove the J2 jumper from the AD1273 printed circuit board: 2) Remove the chassis from the chassis housing. 3) Remove the four PCB cover retaining screws. 4) The jumper (labeled J2) is located to the left of pin number one on the 7-Pin connector attached to the PCB (see Figure 7). 5) Gently remove the jumper and store in a safe location. 6) Reassemble the dome in the reverse order of the disassembly.
CONNECTIONS AD1273 CONNECTIONS Data Line Connections Data line connections to the AD1273 are made with usersupplied, 2-wire twisted pair, shielded, Belden 8760 or equivalent (Plenum 88760). The maximum data line length is 5000 feet (1524m). Data lines enter the AD1273 through a 7-pin Plug and Ramp connector unit (see Figure 8). The 7-pin Ramp connector is attached to the AD1273 printed circuit board. The 7-pin Plug mating connector is shipped with the AD1273 unit.
AD1273 CONNECTIONS Power Connections Wire Selection The 24VAC power lines enter the AD1273 through a 7-pin Plug and Ramp connector (see Figure 9). The 7-pin Ramp connector is mounted to the printed circuit board. The 7-pin Plug mating connector is shipped with the AD1273 unit. Table 6 lists the wire gauge versus maximum distance allowed between the AD1273 pan/tilt and the voltage source. Shielded cable is recommended for most applications.
INSTALLATION AD1273 INSTALLATION 1) Determine the ceiling tile for the AD1273 installation. Obtain adequate working space by removing that tile and two or three tiles immediately surrounding it. 2) Determine a location in the building frame centered above the intended installation site for securing a safety chain to the AD1273 chassis housing (see Figure 11).

INSTALLATION AD1273 Direct and Remote Hard Mount Direct hard mounting refers to bolting the AD1273 housing directly to a ceiling. Remote hard mounting involves locating the housing from a raised ceiling or a building frame through the use of pipes and flanges (not provided). 2.0" 50.8 mm 2.0" 50.8 mm 7.125" 181 mm 2.0" 50.8 mm 3.5" 90 mm Ceiling Preparation Two circular bolt patterns are located in the roof of the AD1273 chassis housing (see Figure 12).

INSTALLATION AD1273 1*) Slide the pendant shroud over the user supplied 1 1/4inch mounting pipe (see Figure 15). Pendant Mount Mounting the AD1273 in a pendant configuration requires using a pipe flange bolted to the chassis housing, a length of pipe determined by the installer, and a second pipe flange bolted to the ceiling, the building frame, or the foundation. 2*) Slide a hose clamp (not supplied) onto the mounting pipe to hold the pendant shroud out of the way during installation.

INSTALLATION AD1273 Chassis Installation 1) One end of the 18-inch safety cable (provided) is connected to the top of the AD1273 chassis at the factory. Attach the free end of the safety cable to the clip attached to the inside center of the chassis housing (see Figure 16). Prior to installing the chassis in the chassis housing, set the 8position DIP switch and the camera number thumbwheel switches. Both switches are mounted on the printed circuit board located on top of the chassis.

INSTALLATION AD1273 Lower Dome Installation Lower Dome Ball Stud Positive Engagement Align the viewing port (clear area) of the lower dome with the camera lens. The lower dome attaches to the chassis frame via four ball studs connecting to four clips on the AD1273 chassis. The bubble is correctly installed when the shoulders of the ball studs are in complete contact with the shoulders of the chassis clips.
AD1273 INSTALLATION Fascia Plate Installation Trim Ring Installation 1) Push the plastic safety lanyard attached to the fascia plate into the lanyard tab slot on the chassis frame. The tab must be all the way through the tab slot to prevent accidental dropping of the fascia plate (see Figure 18). An optional trim ring (part number AD1273/TR) is available to improve the final appearance of installations that require cutting the existing ceiling or drop ceiling tile.
INSTALLATION AD1273 Pendant Shroud Installation This procedure applies only to pendant installations using the pendant shroud. These instructions complete the pendant mount installation procedure (refer to page 16, Pendant Mount). NOTE: Verify that the chassis, the lower dome, and the fascia cover installation procedures are complete before proceeding with the pendant shroud installation.

OPERATION AD1273 OPERATION Stopping Autopan The AD1273 Series dome uses AD Manchester Control Code for pan/tilt positioning, camera zoom, camera focus, and lens iris functions. A single Manchester Control Code (data) line provides uni-directional support for a group of 64 camera & pan/tilt units (see page 6, Camera Number Assignment). Larger systems use one additional Manchester Control Code line for each additional 64 cameras (see page 6 - Camera Number Sequencing).

OPERATION AD1273 Special Commands The following is a list of special AD Manchester Control Code commands available to the AD1273. RESET DOME - (65 CALL then 65 SET) This command sequence resets the dome and enables Auto Iris mode (color cameras only). The Iris defaults to the factory setting. AUTO IRIS - (70 CALL) This command enables the auto iris with the current set point. Iris control commands move the set point. This is the default state of the dome.

ADJUSTMENTS AD1273 ADJUSTMENTS Backlash Adjustment 6) Repeat the measurement process four times, using a different location (typically between the gear spokes) on the pan axis drive gear. Proper backlash adjustment eliminates any apparent video image hesitation during a slow pan rotation through 360 degrees. Also, when the pan action stops, the video image should not bounce back and forth. NOTE: During the cooling process, gears tend to warp slightly and develop a “high” point.

ADJUSTMENTS AD1273 Lens Tracking Adjustment When connected to a monitor, the image generated by the CobraDome camera must stay in focus during transitions from telephoto mode to wide angle mode. 11) Manually zoom in on the object (i.e., increasing the magnification) using the zoom ring ⑧. 12) Rotate the tracking adjustment wheel ➉ until the object appears in focus. If an image losses focus during the transition from tele to wide angle, the lens tracking needs adjustment.
