Automatic Fire Sprinkler System

A fire sprinkler system is a protective measure against fire that contains water supply and the required pressure and a distribution system. They are mostly used in commercial buildings and factories although nowadays even residential buildings use automatic fire sprinkler systems. Fire sprinkler systems contain Isolating valves used to stop water supply. It has a distinct red color and is usually locked to allow free water flow. The valve monitor is used to monitor the state of the isolating valve. The alarm valve used to control flow of water in the fire sprinkler system. The automatic fire sprinkler system also contains the sprinkler head, alarm tests and a bell (Corinne, 2009).
Inspection, testing and maintenance of fire sprinkler systems are critical exercises that should always be done on regular basis to ensure that in case of a fire emergency the sprinkler actually works
Inspection Form
Automatic Fire Sprinkler Systems

Gauges - Dry, Pre-Action & Deluge

They should be inspected once every week to make sure that the correct levels of air and pressure is maintained always
Gauges - Wet Pipe Systems

Inspection should be done monthly to ensure correct water supply pressure just incase there is a fire emergency
Alarm Devices

Verification should be done quartely to ensure there is no damage to the devices.
Hydraulic Nameplate

This need to be inspected quartely

Inspection should be done annually especially prior to winter to ensure that all openings are working correctly

Sprinkler pipe hangers and seismic braces shall be inspected annually.
Pipe & Fittings

Pipes and fittings should be inspected annually.
Sprinkler Heads

Spare Sprinkler Heads

Alarm Devices

Waterflow alarm devices including, but not limited to, mechanical water motor gongs, vane-type water flow devices, and pressure switches that provide audible or visual signals shall be tested quarterly.
Antifreeze Solution

The freezing point of solutions in antifreeze shall be tested annually by measuring the specific gravity with a hydrometer or refractometer and adjusting the solutions if necessary.

Gauges shall be replaced every 5 years or tested every 5 years by comparison with a calibrated gauge. Gauges not accurate to within 3 percent of the full scale shall be recalibrated or replaced.
Sprinkler Heads

Sprinklers that have been in service for a long time mostly more than fifty years should be replaced. Samples should also be taken to testing laboratories to ensure that the sprinkler heads are of desired quality.
Sprinkler Heads - Extra High Temp

Temperature is a key parameter that should always be kept constant. The rigt temperature should therefore be continuously tested.
Sprinkler Heads - Fast Response

They should be tested at ten year intervals to ensure they are working properly.


Valves (All Types)

(See "Valves" below)
Obstruction Investigation

Systems shall be examined internally for obstructions where conditions exist that could cause obstructed piping. If the condition has not been corrected or the condition is one that could result in obstruction of piping despite any previous flushing procedures.
Control Valves

Inspection of valves should be done on a weekly basis.
Alarm Valves

Inspection for alarms should be on a monthly basis.
Check Valves

Inspection is usually after every five years to ensure proper operation free movement and to ensure that the valves are in good condition.
Preaction/Deluge Valves

Inspection of pre-action valves is done annually
Dry Pipe Valves/Quick Opening Devices

Inspection of dry valves should be done annually to ensure proper functioning.
Backflow Prevention Assemblies

Backflow preventers should be inspected annually

It is very critical to have properties to have an efficient sprinkler system. Developers and property owners currently adopt the sprinklers systems because of the following reasons. Building regulations in many local authorities recommend installation of sprinkler system as a precautionary measure in cases of fire emergencies. Insurers also recommend installation of sprinkler systems (Firewize, 2013). They go extra measures by refusing to insure properties that lack sprinkler systems therefore property owners are forced to install these systems as property protection measures. In cases of business continuity in cases of fire emergencies, it is critical to install sprinkler systems.

Automatic Nervous System

...An elderly patient in a nursing home has recurrent episodes of fainting when he stands. An alert nurse notices that the fainting occurs only whenhis room is fairly warm; however, on cold mornings, he has no difficulty. What is the cause of the fainting and how does it relate to the autonomic nervous system and room temperature? Age- related changes and environmental temperature play a significant role in the sympathetic vasoconstriction effect of the autonomic nervous system. Actually, the episodes of fainting when he stands is normally seen in the elderly upon suddenly arising from a reclining or sitting position as long as the average decrease in the blood pressure is just around 20 mmHg of the...

Carbon Dioxide Fire Suppression System

...Hazards of Carbon Dioxide Fire Suppression System Carbon dioxide suppresses fire hazards through a thermophysical mechanism wherein reacting gases that contribute to the fire are prevented from achieving high temperatures. Senecal (1999) has shown that the gas works by diluting the concentration of fire-reactive gases therefore slowing the rate of flame chemistry. Benefits in using this gas includes not needing superpressurization, none reactivity with most materials and not needing a clean-up agent because it leaves no residue. The risk associated in installing and using Carbon Dioxide as a fire suppressant in an occupied area lies in...

Automatic identification systems (AIS)

...Automatic Identification System (AIS) Introduction On land, a four way intersection is considered a possible threat to collision for crossing vehicles. Traffic lights and stop signs are used to guide and control motion of vehicles to avoid accidents. At the sea, there are no roads or stop lights or traffic lights. Buoys are used to partially highlight passageways for ships especially in front of harbors and heavy traffic areas. Rules of the road were stated for ships to follow to clearly decide on the right of passage and avoid confusion to ships as to avoid collision at sea. In open water, ships sail under different courses and speeds, each following its schedule to arrive to its destination. A ship detected by visual lookouts... is on a...

Automatic and effortful processing

...AUTOMATIC AND AFFORTFUL PROCESSING Encoding processes exist on a continuum of attention requirements, with those requiring little or not attention on one end and those require a lot of attention and effort on the other. The former is referred as automatic processing and the latter as effortful processing. Experimental evidence supports the theoretical distinction between automatic and effortful processing cognitive processes. Compared to effortful processes, automatic processes require minimal amounts of attention capacity, and are relatively resistant to the influences of effort and concurrent tasks. In the last twenty years several researchers have proposed a...

Automatic Stabilizer

...AUTOMATIC STABILIZERS To maintain a nation's economic balance, aside from fiscal policy, automatic stabilizers are employed. Without any direct intervention from the government, it functions as a means of adjusting its expenses when there is a threat to bring the national economy off balance. Having been built into the government structure, ratification of any new laws or approving of bills through a governing body becomes unnecessary. This avoids long process of acquiring financial authorization, ensuring that vital adjustments can be applied with no delay. Automatic stabilizers primarily deal with minor shifts that could harmfully affect one or more sections of economic classes. They...
