In a 180-foot long corridor that is 10 feet wide, how many heat detectors are required if they have a listed 30-foot spacing?

To determine the number of heat detectors required in a corridor, it's important to consider the spacing guidelines set by the detector’s listing. In this scenario, the heat detectors have a maximum spacing of 30 feet apart.

Given a corridor that is 180 feet long, the total length can be divided by the spacing requirement of 30 feet. Dividing 180 feet by 30 feet results in 6. This indicates that 6 detectors can be placed along the corridor maintaining the maximum spacing stipulated.

However, it is essential to remember that at least one heat detector is required at each end of the corridor to ensure coverage. Since the layout allows for 6 detectors to fit within the 30-foot spacing rule, there is an opportunity to maximize detector placement. The correct approach would typically involve placing a detector at each end of the corridor and filling in the necessary spacing along the length.

By considering the endpoints and the spacing, the configuration will indeed confirm that 6 detectors can be effectively utilized along this corridor, ensuring the entire length is adequately protected. Thus, the determination of 6 heat detectors as necessary aligns with both the spacing requirements and the need for coverage, making the conclusion of the answer appropriate.

In this context, the answer indicating
