Type of System


Sprinkler System Definitions

The flanged supply that terminates the underground supply pipe inside the building.
Generally a vertical supply pipe that initially supplies the entire sprinkler piping network. The sprinkler riser is generally the location where a transition from underground piping to interior piping occur.
First main supplied from the sprinkler riser. The cross main will generally be installed parallel to the buildings roof structure.
A transfer main that is supplied by the riser or cross main to supply a separate or area not supplied from the cross main
A vertical pipe that supplies sprinkler lines from the cross main.
Generally horizontal piping supplied by the riser nipple From the cross main. Sprinkler heads may be installed directly on the Branch line or sprinkler heads will be supplied from the branch line.
A sprinkler head that is installed on the top of the sprinkler piping. An upright sprinkler is installed close to the ceiling so the operating element of the sprinkler will operate quickly in a fire.
A vertical drop from branch line piping to supply a sprinkler. Drop nipples supply sprinklers located finished ceilings.
A sprinkler installed to discharge down towards the floor. A pendent sprinkler can be installed directly on the sprinkler branch line or from a drop nipple.
An alarm that activates when there is water flow into the system. The water flow alarm device is generally located on the sprinkler riser at the initial supply of the system. All sprinkler systems must have water flow alarms.
A valve on the sprinkler system that is opened Periodically to simulate a water flow through the riser. The valve is Opened to make the water flow alarm to operate.
A discharge pipe and orifice from the Inspectors test valve. The orifice that must be placed in the connection Is the same as the smallest orifice sprinkler on the system. This creates The most demanding water flow for the water flow alarm device.

System Inspection


The National Fire Protection Association Journal of Standards places the responsibility of sprinkler system inspection and maintenance on a building’s owner. Bay Line Fire Protection is widely considered an industry leader with over 47 years of experience in fabricating, installing, maintaining, and certifying fire protection systems. We perform quarterly, semi-annual, and annual inspections to help building owners comply with the regulatory requirement.


Inspection Format

Inspect sprinklers visible from floor level (not required of sprinklers in concealed spaces) for corrosion, paint, damage, and proper installation. Check for obstructions to sprinklers. Note any problems on report. Test sprinklers on old systems with standard sprinklers after 50 years. Test systems with quick response sprinklers after 20 years.
Inspect pipe and fittings from floor level – to be in good condition, not subject to external loads, and not exposed to freezing conditions
Hangers inspected from floor level – to ensure they are not damaged or loose.
Pressure Gages – Inspect monthly (owner) and annually – our inspection for damage. Gauges must be replaced or tested every 5 years.
Water Flow Alarm Devices – Must be free of damage and debris. Test alarms to be sure they operate – wet system via inspector’s test; dry system – see dry system detailed inspection routine.
Check all system control valves for normal position, damage, or leakage. Note if valves are sealed, locked, provided with tamper switch. Sign in place.
Check Fire Department connection – free of damage, debris – easy access for Fire Department couplings, caps are in place and in good condition. Clapper operates correctly. Check valve does not leak. Ball drip in place and operates correctly. Sign in place.
Main drain test performed – compare results to previous tests to determine if there has been any change in water supply.

-Hydraulic placard
-Appropriate signs
-Correct number of spare sprinklers -and wrenches
-Added / removed ceilings, walls, mezzanines-change in occupancy
-Test freezing point annually
Same as wet system for inspection of sprinklers, piping, fittings, hangers, control valves, Fire Department connections, signs, placards, etc. – Building changes
Partial trip test of dry pipe valve required annually – means testing of valves operation without completely filling system with water.
-Must also trip-test quick opening device separately from dry pipe valve
— Test water flow alarm via by-pass line
— Test low-air alarms, if provided
— Reset quick opening device and dry pipe valve after test per manufacturer instructions
— Full-flow trip test of dry pipe valve required every three years

In addition to visual inspection of piping, hangers, etc., dry systems require every five years visual inspection of interior of piping to check for corrosion. If corrosion in severe, recommend flushing of entire system to owner.
