Fire Sprinkler Systems – Your Last Line of Defense

An automatic fire sprinkler system is the only guaranteed way to provide total fire protection in your facility. The fire sprinkler is the last line of defense in preventing fires from spreading, and hopefully stopping them entirely. When choosing your fire protection system, it is important to choose the right fire sprinkler system, that addresses the needs of your specific facility. Below are the 6 most common types of sprinklers on the market:

wet pipe sprinkler system1. Wet Pipe Sprinklers – The most common type of fire sprinkler system. A wet pipe system is easy to maintain and install. Wet pipe systems are filled with water with specific sprinkler head spacing. Each sprinkler head acts as its own heat detector. During a fire, the heat causes the core of the sprinkler head to burst discharging water. Not all the sprinkler heads are activated at once since each head is its own detector. The head will only burst when exposed to heat or broken off by physical contact. The advantage of this independence is that it can help to significantly reduce damage in the event of a false alarm since water will only be released from one head. It is not a surprise this type of system is still the most common application in the industry to this day.

dry pipe sprinkler system2. Dry Pipe Systems – A dry pipe sprinkler system is much like a wet pipe system except that the water is not contained within the pipes. Instead of water, the pipes in a dry system are pressurized by air or nitrogen. Water is still used to suppress a fire in these systems but is held back by a valve until the system is activated. A dry pipe system is a perfect application in environments that experience extreme cold where a wet pipe system would be subject to pipe freezing and impairments to the fire protection.

 

pre-action sprinkler system3. Pre-action Sprinkler Systems – A pre-action system is a dry pipe system where the water is held back by an electronically controlled valve that is connected to a fire detection system. Only after the fire detection system is activated will water enter the systems pipes and each sprinkler head is activated individually. A pre-action system is great for applications where accidental discharge of sprinklers would cause extensive damage like data centers and libraries.

deluge 4. Deluge Systems – A deluge sprinkler system is specifically designed for high-hazard areas in a building. In this system design, the pipes are dry and unpressurized, sprinkler heads are open, connection to a water source directly, and water is held back by a valve. When the system detects a fire, water is pumped through the systems pipes and is discharged through all the open heads flooding the affected area.

 

in-rack5. In-Rack Sprinklers – In-rack fire sprinklers are used in warehouse racking systems to contain fires to small areas and prevent the entire racking area from being ruined by a fire. These sprinklers are designed and located in close proximity to racking areas often installed in the middle of each aisle with heads on every level of the rack.

 

esfr sprinkler system6. ESFR – Early Suppression Fast Response systems are another fantastic application for warehouses. An ESFR systems heads are designed to emit a higher concentration of larger droplets of water. ESFR systems are high volume, high velocity systems and can be located in the ceiling to protect storage areas in place of in-rack sprinklers.

Fire Alarm Signals – What Are They?

How many times has your Fire panel annoyed you with a beeping “alarm” going off? Many people don’t realize that panel “alarms” are not actually alarms at all, they are often supervisory and trouble signals – how can you tell the difference?

The Difference Between Alarm, Supervisory, and Trouble Signals

Alarms are simple – they are saying “Hey! There is an actual fire event happening in your facility! GET OUT!” These signals can be created by a smoke detector, manual pull station, or a sprinkler system being activated. Regardless of what caused the alarm, this is what will set off the notification devices that get people to evacuate the building and prompts the system to call for emergency fire response.

Supervisory signals indicate that investigation into your fire systems is needed immediately – don’t worry, the threat is not serious enough to cause an alarm yet. These signals can come from a duct detector that activates, fire alarmor a fire sprinkler device has been tampered. Address the issue before it causes potential damage.

Trouble signals on the fire panel show that there is something wrong with the fire system, but not quite an emergency situation. It could be a problem with the wiring, a broken device, or something wrong with the fire panel itself. Trouble signals are many times minor issues that do not rise to the level of needing immediate emergency repairs.

How Do I Know Which One Has Been Set Off?

An “Alarm” signal will have a red light or LED lit on the fire panel and there will be a steady tone sounding fromFire safety the panel. Also, any notification devices (horns, bells, strobes, speakers) will be activated. In every case when the system is monitored, the fire department will be dispatched.

A “Supervisory” signal will have a yellow light or LED lit on the fire panel and there will be a fast beeping tone sounding from the panel. There should not be any notification devices going off.

A “Trouble” signal will also have a yellow light or LED lit on the fire panel and there will be a slower beeping tone sounding from the panel.

With any of these signals, most fire panels will also have a digital display that will tell you what type of signal is active. With analog (programmable) systems, the display may also show you the exact location of the issue.

How to Respond to Each Signal

If there is an Alarm on your fire panel, you should always make sure that all personnel is evacuated from the building and is safe and accounted for. Following that, immediately contact your fire service provider to dispatch a service technician.

For a Supervisory signal, you should call your fire system service provider immediately. Depending on what the specific issue is being displayed, your provider should be able to determine whether it requires immediate service or not.fire inspection

With Trouble signals, you will want to call your service provider, but it can wait until normal business hours. There is no need to spend extra money for an emergency after hours service call.

Knowing what signal your fire panel is displaying and how to respond is very important. It will help you to understand what steps to take and can potentially save your company time and money.
