Sleek cover, neatly finished
The thermostat cover looks nice in the hallway. Children can no longer reach it and the material feels sturdy. The assembly video was helpful.
The STI 13120EG-NLD is the successor to the renowned STI 6535/D. This robust protective cover made of UV-stabilized, hardened polycarbonate is designed to prevent false alarms in fire alarm control panels. The cover is suitable for outdoor applications and is easily placed over a surface-mounted manual (fire) detector. The integrated 96 dB deterrent alarm (siren) sounds as soon as the cover is opened, strongly discouraging misuse while keeping the detector immediately accessible in emergencies.
This product has been successfully used worldwide for years in schools, universities, hospitals, hotels, care institutions, and public buildings. Wherever false alarms cause nuisance, costs, and unnecessary evacuations, this protective cover offers a reliable solution without hindering operation in emergencies.
The cover is made of UV-stabilized polycarbonate and remains reliable between -40 °C and +49 °C. Thanks to the IP54 sealing, the model is suitable for both indoor and outdoor use. It is a surface-mounted model with an open back; vertical mounting is recommended. Due to the curved shape, the specified depth may vary slightly.
The version is supplied with a clear red label with Dutch text:
IN CASE OF FIRE – LIFT COVER / ACTIVATE FIRE ALARM
The cover is made of impact-resistant polycarbonate, suitable for surface-mounted manual call points and easy to place over an existing detector. Besides this version, variants are available in other colors, label texts, and mounting options.
Height 138 mm, width 116 mm, depth 101 mm.
The packaging contains the protective cover, a gasket set, mounting materials, and an installation manual.
The STI 13120FR-NLD complies with IP54 and is UL/cUL Listed. The product comes standard with a three-year warranty against breakage under normal use; the polycarbonate has a lifetime warranty under normal use.

We have installed 12 of them in the sports hall. No more damage from playing football and it still works perfectly with the test alarm.
Net model, hardly visible on the door. Installation was simple, although no drilling template was included. Closes smoothly.
User-friendly solution. Visitors can no longer adjust the temperature, but it remains easy to read. We will order more.
Our outside door always slammed shut. With this door closer, it closes smoothly, even in the wind. Adjusting the speed was child's play.
Sturdy metal cage. Protects against balls in the gym without blocking the alarm signal. Would have liked to see extra screws included in the box.
Exactly what we needed at the office. Colleagues can no longer fiddle with the buttons, yet there is still good airflow all around. Installation with 4 wall anchors, done.
Installed on the warehouse door within 20 minutes. The closure is gentle and makes hardly any noise. Mounting plate fit perfectly, clear instructions.
