An initiating device covers how many feet per floor or how many devices?

The correct answer regarding the coverage of an initiating device is based on established guidelines which specify that an initiating device should effectively cover a specific area and be limited to a certain number of devices per floor to ensure optimal functionality and response to fire incidents. In this case, the standard is to cover 20,000 square feet per floor and permit a maximum of 25 initiating devices. This ensures that any initiating device is positioned effectively to detect conditions that could lead to a fire while adhering to safety protocols.

This standard is important because it balances the need for adequate coverage in larger spaces while preventing overcrowding of initiating devices, which can lead to confusion or delayed response times in an emergency situation. Proper spacing and quantity of initiating devices are key to ensuring reliable performance in fire prevention systems.
