Pre-Installation

1. Carefully unpack screen and remove outer wrapping from case.
2. Make sure to recheck measurements of screen location before installation.

Installation

NOTE: Unit is not to be installed in air handling spaces.

1. The case brackets provide multiple attachment points for bolts, cables, or threaded rod. The following page shows two locations for typical threaded rod installations with the external case mounting brackets (Figure 1a) and without them (Figure 1b). The internal case brackets can be accessed through the hand holes (Figure 1c).

Figure 1b - Threaded Rod with Internal and External Bracket

Figure 1c - Internal Bracket

1. The case has a self-trimming flange around the bottom. Ceiling tiles or drywall may be placed on top of this flange to provide a finished appearance.
2. After securing the case in the ceiling, check that the case is level and plumb.
3. Use supplied 1/8" nex key and a 1/4" wrench to remove silver shipping brackets attached to slat and screen case.
4. Install electrical connections that apply to your unit. Refer to the electrical diagram'. The electrical connections are accessible by removing the two screws on the primary junction box cover and the two screws on the secondary low voltage cover (Figure 2). You can remove the access door if needed to allow for greater access to the electrical wiring. To remove the access door; remove the screw from each end of the door while holding the door and slide the door off the flanges (Figure 3).

NOTE: Must be installed in accordance with the requirements of the Local Building Codes, the Canadian Electrical Code (CEC), CAN/CSA C22.1 and the National Electric Code (NEC), NFPA 70.

1. Remove shipping brackets by removing the hex head screws from aluminum slat and case. Slat should move freely (Figure 2). (Only if the roller assembly is pre installed.)
2. Test installation by operating the screen several times. Be prepared to stop the screen. Standard Duty Cycle: 1MIN. ON/3 MIN. OFF. The fabric door (rear door) will not close until the wall switch is placed in the up position and when the screen motor stops at its limit switch in the up direction.

⚠AUTION: Excessive continuous operation may cause the motor to overheat. If this happens the motor will shut off until it cools to a normal operating temperature.

1. Run the screen down enough to open the fabric door. Insert the access door on the flanges and reinstall the screws to secure the door.

NOTE: Unit is to be used with a camera weighing no more than 8 pounds. Camera and camera cables NOT included.

1. Run the camera arm down and then disconnect the power to the unit.
2. Install the camera cables through the cable loops. See Figure 4. Start from the camera shelf and then up the arms through the camera cable exit in the end of the case.

NOTE: The camera cables must not interfere with the arm or door mechanisms. Leave enough cable to allow for a natural bend at the pivot points (Figure 4). Use cable ties if needed to secure the camera cables through the loops. Do NOT go around the camera arm tubes with wire ties.

1. Connect camera to the cable(s) and secure the camera to the camera shelf. The camera shelf is perforated for easy camera attachment (Figure 4).
2. Check the camera cable path and ensure there will not be interference with the arm or door mechanism operation.
3. Reconnect power to the unit and test operation.
