Product Overview

Fire doors play a vital role in passive fire protection by compartmentalising fires and delaying the spread of smoke and flames throughout a building. In many cases—particularly in plant rooms, storage areas, and restricted-access zones—fire doors must be kept locked at all times to maintain their effectiveness and prevent unauthorised access.

The Smiths Architectural Fire Door Keep Locked Sign communicates this critical instruction clearly and effectively, helping building owners and facilities managers ensure that fire safety procedures are followed consistently.

Its self-adhesive vinyl construction enables fast and clean installation with no need for mechanical fixings such as screws, nails, or drills. This makes it ideal for modern interiors, listed buildings, or locations where preserving the integrity of the door surface is important.

Key Features and Benefits

Full Compliance with UK and European Regulations
This sign is manufactured in accordance with all current UK and European fire safety signage regulations, including:

• BS 5499: Part 1 & 5, which outlines best practices for fire safety sign design and placement.

• Health and Safety (Safety Signs and Signals) Regulations 1996, which govern the mandatory use of safety signs in workplaces and public buildings.

Compliance with these standards ensures the sign provides legally required warnings and instructions, helping businesses avoid potential fines and maintain a safe environment for building occupants.

Self-Adhesive Vinyl for Fast Installation
The sign is made from durable, self-adhesive vinyl, allowing for instant application. It requires no drilling, no screws, and no additional hardware. This adhesive backing adheres easily to clean, dry, smooth surfaces such as wood, metal, painted walls, glass, and most door materials.

This feature dramatically reduces installation time and is ideal for buildings that require rapid fire safety upgrades or where traditional fixing methods are impractical.

Compact 100mm x 100mm Format
The sign measures 100mm by 100mm, making it compact yet highly visible. This size is optimal for placement on fire doors where space may be limited or where multiple signs are in use. Despite its small footprint, the design ensures the instruction remains legible and prominent.

High Visibility Design
The sign features bold, easy-to-read text and is printed using high-contrast colours consistent with fire safety signage conventions. This ensures it stands out even in dimly lit environments, and its layout follows established graphical standards to maximise recognition and understanding in emergency situations.

No Tools or Surface Damage
Thanks to its peel-and-stick design, this sign can be installed without damaging door surfaces. It is particularly useful in settings where aesthetics or structural integrity must be preserved, such as office interiors, heritage buildings, or medical facilities.

Durable and Lightweight Construction
Despite its professional quality, the sign is extremely lightweight at just 100 grams, making it easy to handle and position. The boxed product dimensions are 10.0cm (width) x 10.0cm (height) x 0.0cm (depth), which ensures compact, efficient storage and transportation for facility management teams or contractors.

Common Use Cases

This fire safety sign is suitable for use in locations where fire doors must remain locked to prevent unauthorised entry or to enhance the fire containment capabilities of the building. Common application areas include:

• Electrical and plant rooms

• Storage areas for hazardous or flammable materials

• Staff-only or secure access areas

• Maintenance corridors and utility shafts

• Restricted areas in hospitals, laboratories, or data centers

• Commercial buildings with high-value inventory or equipment

In each of these settings, clear and visible safety signage is critical to enforcing compliance and supporting emergency response strategies.

Installation Instructions

1. Ensure the surface is clean, dry, and free from dust or grease.

2. Carefully peel the backing paper away from the vinyl sign.

3. Align the sign to the desired position on the door or wall surface.

4. Press firmly from the center outward to ensure good adhesion and eliminate air bubbles.

Once installed, the sign will remain securely in place under normal indoor conditions. For long-term performance, avoid applying to textured or damp surfaces.
