Fire Sprinkler FAQ

Here at Frontline Fire Protection Inc, we hear a lot of questions about fire protection, and we’re more than happy to answer. If you don’t find what you are looking for here, feel free to contact us. We’re happy to help.

Q.1 What is an automatic fire sprinkler system?
The automatic fire sprinkler system is the most widely used fire protection system today. The whole philosophy of sprinklers is based upon the premise of applying the right amount of water (as little as possible) in the right place (the seat of the fire) at the right time (as quickly as possible).Unlike in the movies, only sprinklers closest to the fire actually activate.  Most fire sprinkler systems are fed directly from city water mains but water tanks and fire pumps supply high hazard systems to guarantee adequate water flow and pressure.
Q.2 What is a WET fire sprinkler system?
A "wet" fire sprinkler system is constantly charged with water under pressure with the sprinkler seat closed.  When a fire sprinkler head is activated by heat water instantly flows on to the fire.

 A wet fire sprinkler system is the most common system and is installed in areas where the ambient temperature is above 32 degrees F
Q.3 What is a DRY fire sprinkler system?

A “dry” fire sprinkler system is used where a freeze risk may arise.  The dry system is constantly charged with compressed air, which holds the dry-pipe valve in the closed position. When a fire sprinkler head is activated, the air pressure is lost, the valve opens and water flows into the system and on to the fire.

A dry fire sprinkler system is commonly installed in areas where the system piping is exposed to temperatures at or below 40 degrees F.

Q.4 What is a PRE-ACTION fire sprinkler system?
A Pre-Action system is essentially a dry fire sprinkler system, charged with compressed air, in combination with a secondary electrical detection system (heat or smoke detectors).  Sprinkler pipes are only filled with water upon electrical detection and sprinkler activation to avoid accidental water damage.

A Pre-Action fire sprinkler system is commonly installed in high-risk areas such as data processing facilities or cold storage warehouses.


Q.5 Aren't smoke detectors enough? Why do we need sprinklers?

Your home needs working smoke detectors to warn you and your family of an impending fire. But a fire safety system can actually stop a beginning fire in its tracks — often before the smoke detector alarm sounds.
Q.6 How can I maintain my sprinkler system?
Most importantly, have your system periodically inspected by a professional. This will catch any problems before they become major. In addition, maintenance will usually lower insurance premiums.


1.Test the system monthly by opening the test valve and listening for an alarm bell.
2.Know the location of the system shutoff valve.
3. Make sure the system control valve is always open.
4.Have your system reevaluated for needed upgrades when:

- Water supply changes-addition or change of backflow preventer or water meter, or reduction of public water supply.
- Building occupancy or use changes.
- Building changes (walls, partitions, additions).

5. Leave the building and contact the fire department when any activation of the system occurs, even if the fire has apparently been extinguished.


1.Paint the sprinklers.
2.Damage sprinklers (report any damage immediately).
3.Hang objects from any part of the system.
4. Obstruct of cover the sprinklers.
