AOV Control Box - Safety Signs by Caledonia Signs

An AOV Control Box fire safety sign is used to identify the location of the control box that operates an Automatic Opening Vent (AOV) system. AOV systems are critical in managing smoke and heat during a fire, improving visibility, reducing inhalation risks, and maintaining safer evacuation routes. The control box allows authorised personnel or emergency responders to activate, monitor, or override the vent system when needed, ensuring the building’s smoke ventilation functions effectively.

The sign is essential because delays in locating or accessing the control box during an emergency can compromise smoke control, endanger occupants, and increase property damage. Clearly marking the control box ensures trained staff can quickly respond, maintaining proper operation of the AOV system and supporting overall fire safety management. This helps prevent confusion and reduces the risks associated with smoke accumulation in emergency situations.

AOV Control Box signs are typically installed near the control box in plant rooms, corridors, or secured compartments within commercial buildings, warehouses, schools, hospitals, shopping centres, and multi-storey buildings. The sign should be visible and unobstructed to allow rapid identification while remaining secure from tampering. Strategic placement ensures that authorised personnel can act without delay during a fire.

Using an AOV Control Box sign reinforces fire safety awareness and compliance with building regulations. It reminds staff and responders that the control box is a critical operational point in the smoke ventilation system. By guiding personnel to the control box efficiently, the sign supports timely smoke management, safer evacuations, and overall emergency preparedness, helping protect lives and property.

Materials Explained

Below is a more detailed description of the materials this particular safety sign is available in. Helping you decide which sign option is most suitable for your application.

Rigid Plastic: This lightweight, gloss white PVC is resistant to weather, moisture, chemicals, and general wear and tear, making it suitable for harsh environments. Its smooth, solid surface allows for crisp printing of text and graphics, enhancing readability and visual impact. Businesses who choose Rigid Plastic signs benefit from fewer replacements and minimal maintenance, making it a practical investment for reliable and effective safety signs.

Self-Adhesive Vinyl: Self-adhesive vinyl is easy to apply and it is budget-friendly. Its adhesive backing allows for easy application to a variety of surfaces such as glass, metal, plastic, and painted walls, which simplifies installation and reduces setup time. Self-adhesive vinyl provides a clean, professional finish that suits many indoor environments including offices, retail, industrial sites, and vehicles. It is more affordable than many other material types and allows for custom shapes, colours, and graphics.

To achieve high performance in low light conditions and conform to ISO 16069 we recommend using Ultra Bright.

Ultra Bright Photoluminescent Rigid Plastic: Ultra Bright rigid plastic has a photoluminescent (glow in the dark) pigmentation which offers a highly effective, reliable, and energy-free visibility in low-light or blackout conditions, making them ideal for emergency exit applications. The afterglow properties exceed PSPA Class C grade, as measured to DIN 6751, provides razor sharp definition in blackout conditions.

Ultra Bright Photoluminescent Self Adhesive: Ultra Bright self adhesive vinyl is a flexible PVC with photoluminescent (glow in the dark) pigmentation. The self-adhesive backing enables quick, tool-free application on smooth, clean surfaces like walls and doors. The afterglow properties exceed PSPA Class C grade, as measured to DIN 6751, provides razor sharp definition in blackout conditions, making them ideal for emergency escape applications.
