These Doors Are Alarmed - Safety Signs by Caledonia Signs

Serves as a clear warning that opening the doors will activate an alarm system. This helps prevent unauthorised, accidental, or unnecessary use of the doors, especially in high-security or safety-critical environments. By notifying people in advance, the sign acts as both a deterrent and an informational tool, reducing false alarms and helping maintain building security and emergency protocols.

This type of sign is particularly effective in areas with multiple alarmed exits, such as emergency stairwells, fire exits, or doors leading to restricted or sensitive zones. In busy public spaces, someone might unknowingly use an alarmed exit unless properly warned. The sign communicates that these doors are for emergency use only (or authorised personnel), helping maintain controlled access and proper evacuation procedures.

“These Doors Are Alarmed” signs should be placed directly on or near alarmed exit doors in places such as shopping malls, airports, hospitals, schools, office buildings, and industrial facilities. They are especially important where emergency exits are required by law but need to remain secure under normal conditions. The sign should be clearly visible and placed at eye level to ensure that anyone approaching the door understands the consequences of using it.

In summary, a “These Doors Are Alarmed” sign plays a vital role in security, safety, and compliance. It helps reduce misuse of emergency exits, supports orderly evacuations, and reinforces the proper use of access-controlled areas. Clear and well-placed signage is essential to ensure awareness and reduce disruptions caused by false alarms or unauthorised entry.
