STI STI-15020ML Euro Stopper Flush Mount Multi Kit with Integral Sounder
Overview
The STI-15020ML is a protective cover retrofit assembly for break glass fire alarm call points designed to prevent accidental or malicious false alarms without blocking legitimate emergency access. The unit pairs a clear polycarbonate housing with an integral 96 dB sounder powered by 24VDC, delivering an audible confirmation when the cover is lifted. Retrofit installation over existing call points requires four simple fixings and accommodates both flush and surface mount orientations — no modification to the underlying device needed. Glows in the dark for nighttime visibility. Rated for continuous operation across -40°F to 120°F, making it suitable for indoor institutional deployments (schools, hospitals, nursing homes, hotels, public buildings).
Compatibility
The STI-15020ML retrofit cover is designed to mount over standard break glass fire alarm call points in North American and international installations. Compatibility depends on call point form factor and mounting footprint — verify that the target call point accepts a 4-point retrofit bracket. The unit is supplied with one breakseal; additional breakseals are available separately for multi-unit deployments. The 24VDC sounder powered option requires integration into the facility's fire alarm circuit or auxiliary power loop.
Installation Notes
Four-point fixing installation retrofit — no permanent modification of the underlying device. Polycarbonate housing is tested to -40°C to +49°C, suitable for climate-controlled indoor spaces only; not rated for outdoor exposure. The integral 96 dB sounder draws 24VDC; verify available sounder circuit capacity before provisioning. Left or right hinge installation option accommodates different mounting orientations. Break seal replacement required after each activation.
