1.7 Inspections and tests
NOTICE
: The owner is responsible for maintaining the fire
protection system and devices in proper operating
condition.
It is imperative that the system be inspected and tested on
a regular basis in accordance with NFPA-25. Refer to
Inspections and Tests recommended in Viking technical
data describing individual components of the deluge
system used.
The frequency of the inspections may vary due to
contaminated or corrosive water supply or corrosive
atmospheres. For minimum maintenance and inspection
requirements, refer to NFPA-25. In addition, the
AUTHORITY HAVING JURISDICTION
may have additional
maintenance, testing, and inspection requirements that
must be followed.
WARNING !
Any system maintenance that involves placing
a control valve or detection system out of service may
eliminate the fire protection capabilities of that system.
Prior to proceeding any testing, notify all local
AUTHORITIES
HAVING JURISDICTION
. Consideration should be given to
employment of a fire patrol in the affected areas.
