Recreational Vehicle (RV) Technician Practice Test

How is a CO alarm tested?

1. By using a digital multimeter

2. According to the manufacturers' instructions

3. In the presence of carbon monoxide

4. By visual inspection

The correct answer is: According to the manufacturers' instructions

A carbon monoxide (CO) alarm should be tested according to the manufacturer’s instructions because these guidelines are specifically designed to ensure the alarm operates correctly and reliably. Each CO alarm can have different testing procedures based on its design and technology. Following the manufacturer’s instructions helps ensure that tests are done safely and effectively, confirming that the device is functioning as intended. The testing process outlined by manufacturers might involve pressing a test button to verify that the alarm sounds, checking battery levels, or ensuring the alarm has not reached the end of its life cycle. It may also include timelines for regular maintenance checks. Adhering to these directions not only complies with safety standards but also ensures the longevity and performance of the CO alarm. Using a digital multimeter, conducting tests in the presence of carbon monoxide, or performing visual inspections have their place in maintenance and troubleshooting but are not comprehensive or safe methods for testing the operation of a CO alarm as per safety standards.
