Which additional tool is sometimes used to aid aiming a flame detector besides an angle finder?

• A. Laser pointer
• B. Screwdriver
• C. Tape measure
• D. Caliper

Answer: (A)

When aligning a flame detector, you want a clear visual cue of the detector’s aiming path in addition to any measured angle. A laser pointer provides a visible beam that marks the exact line of sight along which the detector will sense flames. This makes it easy to align the detector precisely to the intended target area, especially when mounting is elevated or in low-light conditions. The other tools are primarily for construction or measurement: a screwdriver for hardware adjustments, a tape measure for distances, and a caliper for precision sizing. None of these offer a direct visual cue of where the detector is aiming, so they’re not as effective for guiding alignment as a laser pointer.
