STI KIT-GLR-BB-0 Red GLR Backbox Kit with ½" NPT Plug
Overview
The STI KIT-GLR-BB-0 is a red, tough polycarbonate backbox kit designed to protect manual call points and similar fire alarm devices from accidental activation, vandalism, and environmental damage. It includes a frame, a backbox, and a ½" NPT plug, providing a robust physical barrier that still allows legitimate operation. This kit is specifically engineered for applications where false alarms are a concern, such as industrial facilities, public buildings, and high-traffic areas. The integral sounder (if applicable to the protected device) draws immediate attention to any unauthorized attempt to access the protected unit.
Compatibility
This backbox kit is designed to fit over manual call points and other similar-sized fire alarm devices. While the evidence does not specify exact model numbers, it is intended for devices that fit within the dimensions of the Stopper II frame. The ½" NPT plug is suitable for sealing unused conduit entries or openings on compatible enclosures.
Installation Notes
Installation involves positioning the frame over the device, marking and drilling four fixing holes (using a 7mm masonry drill bit), and securing the frame with the provided screws and wall fixings. A weather gasket is used to seal the unit against the wall. For surface installations, inserts are provided to blank off unused cable entry holes. The ½" NPT plug is designed for standard threaded conduit entries.
