STI-13210NG Pull Station Cover Green Universal Stopper

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-13210NG is a green universal stopper cover designed to protect manual pull stations in fire alarm systems. Sold without a horn and without a label, this unit provides a clean, unobtrusive fit over existing pull station devices. It functions as a deterrent against accidental or unauthorized activation, physically blocking access to the pull station while still allowing intentional emergency use. Licensed fire alarm technicians and security system installers typically specify this cover for applications where an audible local alarm or printed label is not required or is handled separately.

This cover is suited for both commercial and institutional settings where pull station protection is needed without the added horn alert. Typical installations include schools, hospitals, office buildings, and multi-family residential properties where accidental pulls are a concern. The green color provides a visible but non-alarming indicator, distinguishing this unit from red-alert-style covers. It is sold individually as a single unit per package.

• Green housing for visible identification without a red alarm appearance

Compatibility

Installation Notes

Installation should be performed by a licensed fire alarm technician in accordance with local fire codes and NFPA 72 requirements. Disconnect or isolate the fire alarm circuit before working on or around the pull station assembly to prevent accidental system activation. Confirm the stopper cover seats securely over the pull station device before restoring power to the circuit. Do not use this cover as a permanent means of decommissioning an active pull station without proper authority having jurisdiction approval.
