What must all fire/supervisory signals sound like?

1. Similar to alarm signals

2. Distinctive from other signals

3. Quiet and soft

4. Regular and monotonous

The correct answer is: Distinctive from other signals

All fire and supervisory signals must be distinctive from other signals to ensure immediate recognition and appropriate response. This differentiation is crucial in emergency situations where clarity and urgency are paramount. A signal that is easily identifiable reduces confusion, allowing occupants and first responders to react swiftly and appropriately. For example, if fire alarm signals sounded similar to everyday sounds or other signals, there could be a delay or failure in recognizing a fire emergency, which could lead to dangerous situations. The specific tones, patterns, and volumes established are designed to be heard distinctly above normal background noise and ensure that they are recognized as a fire or supervisory alert instantly. This characteristic is fundamental for the safety of occupants in any building or facility, ensuring that they can evacuate or take appropriate actions without hesitation.
