Red call points align with other fire safety equipment and signage, making them easily identifiable in the event of a fire emergency, allowing for swift action.
Green Call Points (Door Release)
Green manual call points serve a different purpose, primarily for door release mechanisms. Typically located near exits, these call points allow individuals to manually release a door during an evacuation. This is particularly useful in situations where electronic access control systems might fail or hinder egress. Activating a green call point overrides the locking mechanism, enabling a safe and swift exit from the building. Their function is crucial for ensuring unobstructed escape routes during emergencies, complementing the fire alarm system by facilitating efficient evacuation procedures.
Other Colors and Functions
While red and green are the most common colors for manual call points, other colors exist to signify different functions within a building’s safety systems. White call points, for example, can be used for emergency warning systems or access control, each color indicates the specific function of the device; The use of varying colors allows for clear differentiation and prevents confusion during an emergency. These specialized call points are designed to initiate specific actions or alerts, contributing to a comprehensive and well-coordinated safety protocol within the facility.
Placement and Location
Manual call points are strategically placed throughout buildings to ensure quick access during emergencies. They are often located along exit routes and in areas with high pedestrian traffic, maximizing their usability.
Strategic Placement in Buildings
Strategic placement of manual call points is crucial for effective fire safety. These devices are intentionally located in areas where they can be easily accessed and utilized during an emergency. Common locations include exit routes, hallways, stairwells, and near doorways. The goal is to ensure that anyone who discovers a fire can quickly activate the alarm, regardless of their location within the building. Proper placement considers factors like visibility, accessibility for individuals with disabilities, and proximity to potential fire hazards. The control panel can also be configured to activate devices depending on the location.
Accessibility and Height
Accessibility is a key consideration when installing manual call points. Regulations often dictate specific height requirements to ensure usability for everyone, including wheelchair users. A common mounting height is around 1.4 meters, making the device easily reachable. Clear signage should also be present to indicate the location of the call point.
