STI-1250NR Weather Stopper Ii Flush Mount Pull Station Cover

Product Description

The SAFETY TECHNOLOGY INTL INC STI-1250NR is a flush mount protective cover designed for fire alarm pull stations. Known as the Weather Stopper II, this cover shields pull station devices from moisture, dust, and environmental exposure that can cause false alarms or component damage. It mounts flush against the wall surface for a clean, low-profile installation. Licensed fire alarm technicians and electrical contractors install this cover as part of routine pull station maintenance or new system installations where environmental protection is required.

The STI-1250NR is suited for applications where pull stations are exposed to humidity, wash-down areas, or outdoor-adjacent environments in both residential and commercial fire alarm systems. Typical install scenarios include building entryways, covered outdoor walkways, warehouses, and any area where airborne moisture or contaminants could compromise the pull station beneath.

Confirm the cover does not obstruct the pull station actuator or tamper with the activation mechanism before returning the system to service.
