The SYSTEM SENSOR SMB500-WH is a white backbox designed to provide a clean, finished mounting surface for compatible detection devices. Backboxes of this type serve as the structural housing base that mounts to a wall or ceiling surface, allowing the detector head or alarm device to attach securely and present a professional appearance. This accessory is installed by licensed electricians or fire alarm technicians during new construction or retrofit projects where a flush or surface-mount housing is required for code-compliant detector installation.
The SMB500-WH is suited for commercial and residential fire detection system installations where a white-finish backbox is specified. It is used in scenarios where the detection device requires a dedicated mounting base separate from the detector unit itself, common in life safety and building automation environments. Installers working on multi-unit residential buildings, office spaces, and light commercial projects will find this backbox appropriate for clean, professional finishes.
Designed as an OEM-style mounting backbox for use with compatible SYSTEM SENSOR detection devices in fire alarm and life safety system installations.
Installation should be performed by a licensed electrician or certified fire alarm technician in accordance with NFPA 72 and all applicable local codes. Disconnect power to the fire alarm control panel and the affected circuit before beginning installation. Secure the backbox to the mounting surface before attaching the detector head, following the detector manufacturer's instructions. Do not apply power to the system until all wiring connections and device mounting are complete and verified.
