The OPTEX BXS-CAP(BL) is a black replacement cap designed for the BX Series photobeam detector line. It serves as a protective and finishing cover component, maintaining the housing integrity of the detector unit. This cap is a direct accessory replacement for field use when the original cap is damaged, lost, or requires a color-matched swap. Installation is handled by security system technicians or low-voltage alarm installers working with OPTEX photobeam equipment in commercial or residential perimeter security applications.
The BXS-CAP(BL) is intended for use with the BX Series photobeam detectors in outdoor or indoor perimeter protection setups. It is sold individually and is suited for service calls where a cap replacement is needed to restore the detector housing to a complete, weather-appropriate condition. The black finish provides a low-visibility profile in installations where aesthetics or concealment are a priority.
Designed as a direct replacement cap for OPTEX BX Series photobeam detectors.
Installation of this cap should be performed by a qualified low-voltage security technician. Power down or disarm the detector circuit before servicing the housing to avoid false triggers or alarm faults. No special tools are typically required for cap replacement. Follow the detector manufacturer documentation and any applicable local low-voltage wiring codes during service.
