The Peerless CMJ500R1 is an adjustable suspended ceiling channel kit designed for mounting equipment, typically projectors, in environments with suspended ceiling systems. This product is UL Listed, indicating it meets specific safety and performance standards, and must be installed by a qualified professional to ensure proper and safe operation. The kit is engineered to provide a secure and adjustable mounting solution, allowing for precise positioning of the equipment beneath a suspended ceiling.
Function Description
The primary function of the CMJ500R1 kit is to provide a stable and secure platform for mounting various types of equipment, most commonly projectors, within a suspended ceiling grid. It is designed to integrate seamlessly with standard 24" x 24" or 24" x 48" false ceiling tiles and T-cross section ceiling runners. The kit includes a ceiling plate, which is the main structural component that rests on the ceiling runners, and various hardware for securing the plate and attaching the equipment.
The system allows for two main types of mounting applications: flush mounting and extension column mounting. For flush mounting, a flush mount tube is threaded through the retaining collar in the adjustable collar mount plate, allowing the equipment to be mounted close to the ceiling. For applications requiring more distance from the ceiling, an extension column (sold separately) can be threaded through the retaining collar, providing flexibility in equipment positioning. An escutcheon plate is included to provide a clean, finished look around the mount tube or extension column at the ceiling tile.
A critical aspect of the CMJ500R1's function is its robust support system. The ceiling tray is anchored to the building's structural elements (wood joists, solid concrete, or truss ceilings) using steel cables. These cables are routed through the ceiling tray and secured with cable locks, ensuring that the weight of the equipment is safely distributed and supported independently of the suspended ceiling grid itself. This design is crucial for preventing damage to the ceiling grid and ensuring the safety of the mounted equipment. The kit is designed to support a maximum UL load capacity of 60 lb (27.2 kg).
Usage Features
The CMJ500R1 offers several features that enhance its usability and adaptability in various installation scenarios:
- Adjustable Positioning: The collar mount plate within the ceiling tray can be slid to a desired position, allowing for precise placement of the equipment relative to the ceiling tile opening. This adjustability is key for aligning projectors with screens or optimizing viewing angles.
- Versatile Ceiling Compatibility: The kit is compatible with common suspended ceiling systems, specifically those with 24" x 24" or 24" x 48" false ceiling tiles and T-cross section runners with a minimum height of 1.5" (38 mm). This broad compatibility makes it suitable for a wide range of commercial and institutional environments.
- Multiple Anchoring Options: The kit provides hardware and instructions for anchoring to different types of structural ceilings:
- Wood Joists or Beams: Utilizes wood screws to secure steel cables.
- Solid Concrete: Requires drilling and the use of concrete anchors and wood screws.
- Truss Ceiling: Allows the steel cables to be looped directly around the ceiling truss, eliminating the need for additional anchors.
This versatility ensures that the kit can be securely installed in almost any building structure.
- Cable Management: The design incorporates cable locks that allow for easy adjustment and tightening of the steel support cables. The cables are routed through specific holes in the ceiling tray, ensuring a taut and secure connection that distributes the load effectively.
- Aesthetic Finish: The escutcheon plate provides a clean and professional appearance at the ceiling level, concealing the mounting hardware and the opening in the ceiling tile.
- Security Features: The use of penta pin screws for certain connections, along with a penta pin driver, adds a layer of security, making it more difficult for unauthorized individuals to tamper with the installation.
- Indoor Use Only: The product is specifically designed for indoor applications. Using it outdoors could lead to product failure and potential personal injury, highlighting the importance of adhering to specified usage conditions.
Maintenance Features
While the CMJ500R1 itself is a relatively low-maintenance component, its design incorporates considerations that facilitate long-term stability and potential adjustments:
- Durable Construction: Made from robust materials, the ceiling plate and associated hardware are designed for long-term durability, minimizing the need for frequent replacement or repair under normal operating conditions.
- Secure Fasteners: The use of self-tapping screws, carriage bolts, and wing nuts ensures that components are held firmly in place. The instructions emphasize tightening screws firmly but without overtightening to prevent damage, which contributes to the longevity of the installation.
- Accessibility for Adjustment: The design allows for the collar mount plate to be slid to adjust the position of the mounted equipment. While this is typically done during initial installation, it suggests that minor repositioning could be possible if needed, provided the ceiling tile opening allows.
- Warning Against Adhesives/Lubricants: The manual explicitly warns against using adhesives, lubricants, or oils to prevent screws from loosening. This is a critical maintenance instruction, as such substances can degrade the casing material, potentially leading to catastrophic failure and serious injury. This guidance ensures the integrity of the mounting system over time.
- Professional Installation Requirement: The mandate for installation by a qualified professional ensures that the initial setup is correct and adheres to safety standards, which is the most significant factor in minimizing future maintenance needs and ensuring long-term reliability. A properly installed system is less likely to require corrective maintenance.
- Load Capacity Adherence: Strict adherence to the maximum UL load capacity of 60 lb (27.2 kg) is crucial for preventing stress on the components and ensuring the long-term stability of the mount. Overloading would compromise the structural integrity and necessitate immediate inspection and potential repair or replacement.
- Regular Inspection (Recommended): Although not explicitly detailed as a maintenance feature, the nature of suspended ceiling mounts suggests that periodic visual inspections of the cables, anchors, and connections would be prudent to ensure continued tautness and security, especially in environments subject to vibrations or other stresses. Any signs of loosening or wear would indicate a need for professional re-evaluation.
