Detection devices that are bulb-type automatic sprinklers and fusible links other than metal alloy type shall be examined and cleaned or replaced ______.

Detection devices that are bulb-type automatic sprinklers and fusible links other than metal alloy type shall be examined and cleaned or replaced ______.

• A. Daily
• B. Weekly
• C. Monthly
• D. Annually

Answer: (D)

Maintenance for heat-responsive actuation devices in sprinkler systems is handled on a yearly cycle. Glass bulb sprinklers and non-metallic fusible links must be examined and cleaned or replaced at least once a year to ensure they will release water when exposed to heat. These components are sensitive to dust, corrosion, and contamination, which can impair heat transfer or prevent the device from activating properly. By checking them annually, you catch buildup or damage that could impede operation, while avoiding unnecessary frequent handling of parts that have long service lives under normal conditions. If a bulb or fusible link shows damage or contamination, clean or replace it promptly, but the baseline requirement is annual inspection and maintenance.
