1.4 System Integrity Verification
Commissioning Safety Systems
Before power up, 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 or output devices
Accessories connected to field and signaling devices
After the initial application of power and any factory specified warm-up period to the
safety system, verify that all signal outputs to and from devices and modules, are
within the manufacturers’ specifications. Initial alignment, alignment checking, and
testing should be performed according to the manufacturers’ recommendations and
instructions.
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 detection should be verified.
Periodic Testing of Field Devices
Periodic testing or alignment should be performed per the manufacturers’
recommendations and instructions. Testing and alignment procedures should
include, but not be limited to:
Verify zero reading
Verify gas reading by applying a Test Gas Film
Verify integrity of all optical surfaces and devices
When testing produces results outside of the manufacturers’ specifications, repair,
or replacement of the suspect device(s) should be performed as necessary. Test
intervals should be independently established through a documented procedure,
including a verification log maintained by plant personnel or third party testing
services.
Periodic System Verification
The following system verifications should be performed at least annually:
Wiring, terminal connections and stability of mounting
Proper system operation verified by performing a full, functional test
of all component devices of the safety system, ensuring that the
proper levels of alarming occur
Fault circuit operation
