Pressurized
Spectra® IV Series

Pendant Back Box
with Fiber Optic Option

C3422M-B (3/08)

Preinstallation
NOTE: This manual is designed to be a reference tool for the installation of your system. For best results and ease of
installation, the dome system should be assembled, pressurized, and tested before installation. A Pressurized Spectra® IV
cable harness (supplied with the back box) is required to test and monitor the pressurized dome.
1. Install the fiber optic module: Open the hinged door to the back box by pushing the tab lock towards the wall of the
unit and lifting the door open. Remove the plug from the 16-pin connector. Install the module in the 16-pin connector.
Secure the module to the circuit board standoff using the screw and lock washer provided.

Figure 1. IInstalling the Fiber Optic Module
2. Connect the back box fiber optic connector to the mating connector on the module. Be sure to route the fiber optic
cables between the plastic housing and the outer wall of the back box before attaching the two connectors. Follow
all applicable instructions provided by the manufacturer of the fiber optic module.
NOTE: All bends in the fiber optic cable must be 1-inch diameter or greater.

Figure 2. Connecting the Back Box Fiber Optic Connector

C3422M-B (3/08)

3. Loosen the V-band attached to the back box and let it hang to the side.

Figure 3. Loosening the V-band
4. Prepare the lower dome for installation:
a.

Remove the O-ring from the lower dome.

Lightly apply O-ring lubricant (supplied) to the O-ring.

Reinstall the O-ring in the groove on the trim ring.

NOTES:
•

Repeated assembly of the unit, without exercising extreme caution to protect the integrity of the O-ring and sealing
surfaces, will result in increased refilling cycles. Plan carefully to minimize service accesses.

•

Use the supplied O-ring lubricant to ensure an airtight seal when installing the lower dome.

Figure 4. Applying O-Ring Lubricant
5. Attach the back box leash to the lower dome, and let the lower dome hang to the other side of the back box.

C3422M-B (3/08)

Figure 5. Attaching the Back Box Leash
6. Install the dome drive. Refer to Table A for a list of compatible dome drives and back boxes.
a.

Set the DIP switches located on the base of the dome drive. Refer to the labels located on the base of the dome
drive or to Switch Settings on page 12.

Line up the blue and red tabs with the blue and red arrows on the hinged door inside the backbox.

Push in the tabs. Insert one side and then the other side. Continue pushing until both sides of the dome drive
click into place.

7. Install the lower dome:
a.

Position the lower dome so that the blower duct inside the back box is between the studs attached to the inside
of the lower dome.

Install the V-band around the lower dome and then tighten the fastener of the V-band.

Test the operation of the unit before pressurizing the dome.

Figure 7. Installing the Lower Dome
8. Pressurize the inside of the dome with nitrogen:
a.

Remove the cap from the Schrader valve of the dome. Place the air chuck from the charging kit over the
Schrader valve.

NOTE: You may use your own charging equipment or Pelco’s EH8000RKIT recharge kit. If you are using your own
equipment, adjust the regulator for an output pressure of 12 psi (83 kPa).

C3422M-B (3/08)

Open the tank valve of the charging kit. Fill the dome with nitrogen for a minimum of five minutes to replace the
oxygen inside the dome with nitrogen.

Remove the air chuck and then replace the Schrader valve cap.

Refer to the Operation/Programming manual (C3412M) for instructions on how to view the current readings for
temperature and pressure. Record the initial temperature and pressure readings of the dome in the space
provided below:
Initial Temperature _______________
Initial Pressure _________________

NOTES:
•

Record the initial temperature and pressure readings for future reference. It is normal for changes in temperature to
cause dome pressure to rise and fall.

•

You must perform an annual refill to be consistent with the intent of the application.

Site Installation
1. Feed a fiber optic cable (not supplied) and the supplied wiring harness into the front of the mount and out the back of
the mount. Connect the wires as required. Refer to Table B, Table C, and Table D on page 10, and Table E on page 11
for cable and wiring information. Fasten the mount to the mounting surface (refer to the instructions supplied with
the mount).

Figure 9. Wiring the Mount
2. Remove the back box mounting plate: Loosen the nuts on top of the back box until they reach the locking material at
the end of the studs, and then turn the mounting plate clockwise and lift.

C3422M-B (3/08)

Figure 10. Removing the Back Box Mounting Plate
3. Thread the wiring from the mount through the mounting plate, and then attach the mounting plate to the mount.
If outdoors, apply thread compound (supplied) to the threads on the mounting plate.

Figure 11. Attaching the Mounting Plate
4. Attach the wire harness connector to the mating connector located on the top of the back box. Connect the fiber optic
cable. Insert the studs and nuts on top of the back box into the mounting plate, turn the back box counterclockwise,
and then tighten the three nuts.
