Periodic System Verification
The following system verifications should be performed at least annually:
Verify wiring, terminal connections and stability of mounting for all integral safety equipment
including, but not limited to:
• Power supplies
• Control modules
• Field detection devices
• Signaling / output devices
• Accessories connected to field and signaling devices.
Proper system operation should be verified by performing a full, functional test of all
component devices of the safety system, ensuring that the proper levels of alarming occur.
Fault/Malfunction circuit operation should be verified.
Calibration intervals should be independently established through a documented procedure,
including a calibration log maintained by plant personnel, or third party testing services.
