How often should alarm notification appliances be tested?

Alarm notification appliances should be tested every 12 months to ensure they are functioning correctly and can provide the necessary alerts during an emergency. This annual testing is critical for maintaining the reliability of the fire alarm system and is often mandated by safety regulations and standards, such as the National Fire Protection Association (NFPA) guidelines.

Regular testing helps to identify any issues with the appliances, such as malfunctioning speakers or notification devices, allowing for timely repairs or replacements. Continuous operational effectiveness is crucial as these devices play a significant role in alerting occupants to evacuate and potentially saving lives in a fire emergency. Adhering to this 12-month testing schedule helps ensure compliance and increases the safety of building occupants.
