Associate Safety Professional Practice Exam

Which of the following is NOT one of the six types of fire protective signaling systems?

1. Local

2. Central station

3. Proprietary

4. Airborne

The correct answer is: Airborne

The correct answer is "D," as airborne is not one of the recognized types of fire protective signaling systems. Fire protective signaling systems are established to detect fires, notify occupants, and alert emergency services. The primary types include local systems, which alert only those within the immediate area; central station systems, which monitor signals and notifications from multiple locations, relaying information to a central facility; and proprietary systems, which are designed for use within a specific facility and are monitored by the owner or designated personnel. Since "airborne" does not fit within these classifications, it's essential to recognize that the recognized types focus on terrestrial detection and communication methods, making airborne an irrelevant term in this context. Understanding these categories helps clarify how fire protection measures are organized to enhance safety in various environments.
