STI-13400NB Universal Pull Station Stopper Cover Enclosed Back

Product Description

The SAFETY TECHNOLOGY INTL INC STI-13400NB is a universal stopper cover designed to protect manual fire pull stations from accidental or unauthorized activation. The enclosed back design provides full surround protection for the pull station housing, preventing nuisance alarms caused by incidental contact, horseplay, or tampering. This cover ships without a label, giving facility managers and installers the flexibility to apply custom signage or leave the unit unmarked as required by the application. It is a single unit sold individually and is installed by fire protection technicians, building maintenance staff, or licensed electricians responsible for fire alarm system upkeep.

The STI-13400NB is suited for use in environments where pull station protection is needed but pre-printed labels are not appropriate or where custom labeling is required. Typical installation locations include schools, hospitals, warehouses, commercial offices, and industrial facilities where false alarm prevention is a priority. The no-label version allows compliance with site-specific signage requirements without the need to modify or cover a factory-printed label.

Installation Notes

Installation is typically performed by fire protection technicians or licensed electricians servicing fire alarm systems. Before installing or removing the cover, confirm the fire alarm panel is in a supervised state and notify the monitoring station to avoid unintended alarm dispatch. The cover should be mounted securely to prevent displacement during normal building activity. All work should conform to applicable local fire codes and NFPA 72 requirements.
