For which type of fire alarm system do firefighters have to search the entire building to locate the activated initiation device?

• A. Noncoded
• B. Coded
• C. Addressable
• D. Monitored

Answer: (A)

Noncoded systems don’t display where the initiating device is located on the fire alarm panel. When an initiation device is activated, there’s no code, zone, or address shown to point responders to the exact device. That means firefighters must search the entire building to find the initiating device, confirm the source of the alarm, and assess the situation. In contrast, coded systems reveal a zone or area where the activation occurred, and addressable systems show the precise device on the panel, allowing responders to go directly to it. This distinction is why the noncoded type is the one that requires a full building search.
