The Stopper II® STI-1100 is a protective cover made of UV-stabilized polycarbonate that helps prevent unwanted and false fire alarms. This version features the text IN CASE OF FIRE – LIFT COVER / ACTIVATE FIRE ALARM and has a powerful warning tone of 95 or 105 dB as soon as the cover is opened.
This version is suitable for flush mount installation and is UL/cUL certified. The product comes with a three-year warranty (one year on the electronics). Thanks to its sturdy construction, the Stopper II® is ideal for places where fire alarm buttons need extra protection against vandalism or accidental activation.
Note: due to the curved shape of this model, the stated depth may vary slightly. Vertical installation is recommended for optimal operation.
The dimensions of the STI-1100 are 137 mm high, 127 mm wide, and 81 mm deep.
VERIFIED VIA TRUSTPILOT
The thermostat cover looks nice in the hallway. Children can no longer reach it and the material feels sturdy. The assembly video was helpful.
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.
