The Notifier CHS‑6 chassis is a rugged, purpose‑built mounting framework that accommodates up to six addressable interface or relay modules in a single enclosure row, offering efficient organisation for fire‑alarm system installations. Designed to fit within Notifier BB‑25 cabinets or the CAB‑3 and CAB‑4 series backboxes, the chassis comes shipped with self‑threading screws for secure fastening to the back wall of the selected cabinet. The CHS‑6 supports the installation of multiple intelligent modules (such as XP6‑C or XP6‑MA) in one compact row, enabling system integrators to consolidate wiring, monitoring, and module mounting in a neat and structured fashion. The metallic chassis frame ensures steady alignment of modules, supports ease of servicing and module replacement, and maintains adherence to fire‐safety enclosure standards. Whether used in new builds or retrofit upgrades, the CHS‑6 helps optimise cabinet space, simplify wiring layout, and deliver durable support for multi‑module fire system components, making it a professional choice for commercial fire‑alarm control installations.
