Fire Sprinkler System Installation, Maintenance, Repair, and Inspection

Learn how fire alarm and sprinkler systems are inter-connected.  Learn what parts and controls are involved, how sprinkler protection systems are designed, fitted, installed, repaired, replaced and the many types of sprinkler systems.

Fire sprinklers are an integral part of a complete fire prevention and protection system.  Since the early 1970’s, they have been mandated for all newly constructed public buildings in British Columbia. Their province-wide implementation has been directly responsible for saving countless lives, preventing wide-scale property damage and stopping the rapid spread of fire.

At Active Fire and Safety Services we provide fire sprinkler installation, maintenance, repair, inspection and testing services in Vancouver and throughout the Lower Mainland and Fraser Valley.

We service the commercial, industrial, institutional and multi-family residential building sectors with all types of fire sprinklers, including common wet and dry systems, as well as highly-specialized and intricate deluge and pre-action installations.

Sprinkler System Design – Types of Sprinkler Systems

There are four basic types of fire sprinkler systems.  At Active Fire, we install and maintain all four.  They are:

  • Wet systems
  • Dry systems
  • Deluge systems
  • Pre-Action systems

The right system depends on many factors.  These include but are not limited to: the type of building, the default temperature of the building, the nature or operational use of the building and BC Fire Code and NFPA regulations.

A sprinkler system is a significant cost for any developer or property manager.  At Active Fire we’ll ensure you choose the right system for your building or operation.

Water and Wet Based Sprinkler Systems for Fire Protection

How wet sprinkler systems work

Wet fire sprinkler systems are the most common and are the easiest and least expensive to maintain and install.

These systems are essentially very simple.  A piping system of black steel, galvanized steel, copper or PVC is installed in a grid pattern in the ceiling.  The pipes are filled with pressurized water supplied via the public water main.  When the ambient temperature near an individual sprinkler head reaches a predetermined point (usually between 57-77°C), the sprinkler head opens, discharging the pressurized water.  Note that sprinkler heads are activated individually – not system-wide.

Wet systems are most commonly used in buildings that maintain consistent temperatures above 4°C and do not house especially flammable operations or unique contents.  For unheated buildings such as freezers, parkades or outdoor patios, dry sprinkler systems are often the best choice.

Dry Fire Sprinkler Systems – Prevent Water Damage

How dry sprinkler systems work

In a dry fire sprinkler system, the sprinkler pipes are filled with pressurized air instead of water.  This pressurized air prevents the clapper valve that connects the sprinkler system to the water main from opening.  As with a wet system, when an individual sprinkler head is activated via an increase in temperature, the sprinkler head opens. However, instead of releasing water, the system initially releases the pressurized air.  Once the air has been released, the pressure against the valve falls allowing  water from the main to flow into the sprinkler pipes and then out the sprinkler heads.  The delay between sprinkler head activation and water release should be no more than 60 seconds.

Dry systems are the second most common type of fire sprinkler installation.  They are most frequently used in unheated warehouses and parkades.

In dry systems, like wet systems, sprinkler heads are triggered on an individual basis and fire containment is confined to affected areas only. For highly flammable operations that would require building-wide sprinkler activation, a deluge system may be necessary.

Deluge Fire Sprinkler System

How deluge fire sprinklers work

Deluge systems are used in commercial or industrial spaces that house highly flammable contents that could cause fire to spread rapidly and catastrophically.

In deluge systems, the sprinkler heads are always open.  Consequently, the system is activated by a secondary source either heat or smoke detectors, or manually.  This secondary activation sends a signal to the alarm panel, which activates the deluge valve that connects the pipes to the water main.  Water then floods the pipes and is dispelled system-wide through all the open sprinkler heads.

Deluge systems often contain a parallel pilot line.  These pilot lines are either wet or dry, ie filled with water or air.  Sprinkler heads which are connected to them are then thermo-activated as in a wet or dry sprinkler system.  This triggers the deluge valve, which then floods the pipes system-wide.

Chemical operations, warehouses, airport hangars, electricity generating stations and other industrial applications are where deluge systems are most commonly used.

Pre-Action Sprinkler Systems – Wet, Dry and Deluge Combo

Pre-Action sprinkler systems are complex and combine elements of wet, dry and deluge systems.

Like a dry system, the pipes are filled with air.  As in a deluge system, the system is activated by a secondary device  (a heat or smoke detector) which sends a signal to the central alarm panel.  This signal causes the valve between the water main and the piping system to open, flooding the pipes with water.  However, it takes another trigger like the automatic sprinkler heads activating to actually release water through the sprinkler heads.

Pre-action systems are used when water damage due to accidental system activation could cause excessive damage to a building’s contents.  They are more complex and costly than other systems, and are used in places that house priceless artifacts, such as museums and libraries, or in computer hubs or other electronic installations.

ESFR – Early Suppression Fast Response (Edward Sam Frank Richard)

Early fire detection and fast response sprinkler system

Early Suppression Fast Response is a system used in more remote locations where the Fire Department is non-existent or would arrive too late to be effective.  Like deluge systems, they are also installed in places with highly flammable contents.  The objective of ESFR is complete fire extinguishment, as opposed to fire containment.

ESFR is usually a wet based system.  However, the water pressure is as much as 3-4 times stronger than in a conventional wet system.  As with the deluge fire sprinkler system, activation is system-wide and not contained to only directly affected sprinkler heads.

Choosing the appropriate fire sprinkler system for your operation requires a number of considerations.  We will ensure you choose a reliable system that will meet your needs.

Fire Sprinkler Suppression System

Fire Suppression systems are fire containment systems that use either chemicals or inert gases to control and extinguish fires in operations where water is not the appropriate extinguishing agent.

Suppression systems are not replacements for sprinkler systems as they are confined to limited areas within a building.  For example: a paint booth or the cooking areas of a commercial kitchen.

These systems are either local, where extinguishers are sprayed directly at the fire source, or total flood. Total flood systems are similar to conventional fire sprinkler systems in that the extinguishing agent is released via an overhead piping system.

View more information about fire suppression systems.

Active Fire installs all types of sprinkler containment and suppression systems.  A professional installation will ensure lives and property are protected.  However, all systems must be inspected and maintained regularly to ensure they function as intended when needed.

Annual Sprinkler System Winterizing Service – Purging to Prevent Pipe Freezing

How dry and wet sprinkler systems are winterized and why this service is important

Winterization is a specialized maintenance service that prevents fire sprinkler pipes in a dry system from freezing or bursting when temperatures hover near the freezing point.

In dry sprinkler systems, water vapor naturally collects on the pipes and then pools at low altitude points in the pipe grid.  If the water remains in the pipe when temperatures drop, the pipes may freeze or burst, compromising the system and damaging property.

A yearly winterization of dry sprinkler systems by purging the system of residual water and then refilling it with compressed air will ensure the pipes remain problem-free throughout the winter.

For wet sprinkler systems in areas where a consistent temperature above 5°C is not always maintainable, antifreeze is used to ensure that the water remains liquid and does not freeze up.

Antifreeze and Glycol for Wet Sprinkler Systems

A solution of antifreeze is necessary for wet sprinkler systems when the ambient temperature could fall to suboptimal levels, or in wet systems that have one or more areas, such as attics, patios or basements, which may experience near-freezing temperatures.

The most common antifreeze agents are glycol and glycerin.  Glycerin is primarily used in PVC piping while propylene glycol is used in non-PVC systems.  It’s imperative that a professional check the level of antifreeze as too little still make the pipes susceptible to freezing and too much may either corrode the pipes or, worse, may make a fire more combustible.

Active Fire routinely checks antifreeze levels during maintenance checks and annual testing.

Sprinkler System Testing and Troubleshooting Checklist

Sprinkler Head Inspection as per BC Fire Code Regulation 2006 Section 2.5

The BC Fire Code mandates that most sprinkler systems be tested on an annual basis.  More complex systems, or operations or buildings with a higher fire risk profile, may require more frequent or in-depth testing and monitoring.  As per NFPA regulations, a typical fire sprinkler inspection will:

  1. Check water pressure
  2. Measure valves are in working order
  3. Ensure that sprinkler heads are activating
  4. Ensure that air pressure in dry systems is sufficient
  5. Check that all pipes are in good condition and devoid of an cracks
  6. Check that signals between the alarm panel and the sprinkler system are working
  7. Check that peripheral devices that activate the system are working

During annual maintenance tests, sprinkler heads are inspected from the floor level.  With older or more complex systems, dedicated sprinkler head testing is also necessary.

Annual Floor Level Loop Sprinkler Testing

Monthly, Bi Monthly, Annual and Semi Annual Maintenance and Replacement

Any sprinkler system that has been in service for 50 or more years will need to have their sprinkler heads tested by an authorized testing agency. All sprinkler heads that have been in service prior to 1920 must be replaced.

Sprinkler heads are inspected to ensure that they are free of corrosion, foreign materials, paint or physical damage.  If any sprinkler head is suboptimal in any of these areas, it must be replaced.

Sprinkler Parts – Sprinkler Head Replacement and NFPA 25 Requirements

There are two basic types of closed sprinkler heads:  metal link or glass bulb.  Glass bulb sprinklers are thermo-activated when a small glass bulb in the sprinkler head breaks due to heat.

Metal link sprinkler heads are activated when an alloy between two metal components within the head melts due to high temperatures. In both instances, the activation causes the head to open up, discharging water.

Sprinkler Head Shapes – Pendent, Upright and Sidewall

Sprinkler heads come in three basic shapes:  pendant, upright, and sidewall.  Most sprinkler heads are pendant, hanging below the sprinkler piping.  In mechanical rooms or hard to reach enclosures, uprights which point up from the piping, may be preferred.  Sidewall heads are installed in walls in places that do not have ceiling piping.

Window Curtain Sprinkler Heads

Window curtain sprinkler heads are placed over windows and form a 180° water arc ensuring that the window stays cool so it can be used as an exit point if necessary.

Sprinkler System (Replacement) – NFPA Building Requirements

System requirements, building limitations and operational uses all determine which sprinkler head fittings are best.

When replacing a sprinkler head the following characteristics of the sprinkler head must be taken into consideration as required by NFPA:

  • Style & type
  • Design density
  • Temperature rating;
  • Special coating on the head
  • Deflector type (e.g., upright, pendent, sidewall);K factor and size
