4.4.2-1 Testing Capabilities

Test controls should be available to initiate operability tests for all essential aspects of the alarm system (including processing logic, audible alarms, and visual alarm indications).

Additional Information:
For those portions of the alarm system (such as audible alarms and visual indications), the test capability should be simple and available to the operators. The more complex portions (such as sensor inputs and logic processing) should also be testable, but by I&C technicians and engineers. Advanced alarm systems, having capability for continuous, on-line, self-testing may satisfy some of these recommendations.
