STI-13200NC Universal Stopper Dome Cover Pull Station

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-13200NC is a universal stopper dome cover designed to protect fire alarm pull stations from accidental or unauthorized activation. The dome-style enclosure mounts directly over an existing pull station, creating a physical barrier that discourages tampering and false alarms. When the cover is lifted or disturbed, it typically triggers a local alert, signaling that the protected device has been accessed. Licensed fire alarm technicians and life safety contractors install this type of cover as part of a complete pull station protection strategy in commercial, institutional, and industrial facilities.

This cover is suited for installations where pull station false alarms are a recurring problem, such as schools, hotels, warehouses, and healthcare facilities. The universal fit design is intended to accommodate a wide range of standard pull station profiles, making it a practical choice when retrofitting existing fire alarm systems without replacing the pull station itself. Installation does not require special tools and integrates with standard surface-mounted pull station hardware.

Installation Notes

Installation should be performed by a licensed fire alarm technician or qualified life safety contractor in accordance with applicable NFPA codes and local authority having jurisdiction requirements. Before installing or servicing the cover, notify the monitoring station and follow facility procedures to place the fire alarm system in test mode. Ensure the existing pull station is securely mounted and fully functional before fitting the dome cover. Do not obstruct the pull station handle in a way that would prevent legitimate emergency activation.
