WARNING
!
Installing or servicing fire protection products such as sprinklers, valves, piping etc. can expose you
to chemicals including lead, which is known to the state of California to cause cancer and birth
defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov.

5. INSPECTIONS, TESTS, AND MAINTENANCE
WARNING
!
Any system maintenance that involves placing a control valve or detection system out of service will
impair the fire protection capabilities of that system. Prior to proceeding, appropriate impairment
procedures per NFPA 25 shall be followed with the notification of all Authorities Having Jurisdiction.
Consideration should be given to employment of a fire patrol in the affected areas.
Failure to follow these instructions could cause improper system operation, resulting in serious
personal injury and/or property damage.
NOTICE
The building owner is responsible for maintaining the fire protection system and devices in proper
operating condition. The Viking VFR-500 Release Control Panel must be kept free of foreign matter
and environmental conditions that could impair its operation. Refer to VFR-500 Installation and
Operation Manual for appropriate testing procedures. For minimum maintenance and inspection
requirements, refer to NFPA 72 and NFPA 25. In addition, the Authority Having Jurisdiction may have
additional maintenance, testing, and inspection requirements that must be followed.
