Texas Fire Alarm License Practice Test

How many fire alarm boxes are required in systems with automatic fire or water flow detectors?

1. At least two, spaced evenly throughout the space

2. At least one, as required by the authority having jurisdiction

3. At least three for redundancy

4. No requirement exists

The correct answer is: At least one, as required by the authority having jurisdiction

In systems that include automatic fire or water flow detectors, the requirement for fire alarm boxes is determined by the authority having jurisdiction (AHJ). This means that local regulations and codes can vary based on the area or specific context of the installation, which makes it crucial for installers and contractors to consult the AHJ for the exact requirements. The decision to mandate at least one fire alarm box ensures that there is a method for manual activation of the fire alarm system, providing an additional layer of safety. This is particularly important in case the automatic systems fail or if immediate human intervention is necessary before the automatic detectors respond. While other choices may suggest specific numbers of fire alarm boxes for redundancy or spacing, the AHJ's determination often reflects the local fire protection needs and standards, so their requirements take precedence over arbitrary numbers. Hence, acknowledging the requirements set by the authority having jurisdiction aligns with best practices for fire alarm systems.
