Jockey Pump Controller

By Darma Sentosa (22/09/2011)

Jockey Pump Controller is used as a tool for controlling the working of the pump to regulate water pressure in the hydrant. Jockey pump controller as a controller used to regulate pressure in the pipe so that when the pressure is reduced, the controller will generate a signal to fire pump works. Application of jockey pump is part of the fire pump control system, where its presence is required by NFPA 20 in clause A-2-19 that the pressure maintenance (jockey or make-up) pump to be used to maintain a relatively uniform high pressure on fire protection systems. The size of the jockey pump should load with the allowable leakage rate is within 10 minutes or 1 gpm (3.8 L / min), whichever is greater. The size of the jockey pump should be small than the fire pump. Schematic diagram of the jockey pump controller as follows:

Hydrant System

By Darma Sentosa (19/6/2011) 

Hydrant is the equipment needed by the firefighters, especially in residential facilities or buildings other than mild extinguishers, hoses and fire-resistant clothing. House or buildings that have a fire extinguisher system installation get a rebate of insurance premiums due to the installation of fire can reduce the damage to property or goods insured.

At first, the fire extinguishing system is done by calling the firefighters and then the officer will explore and drill for water. Water from the drilling pipe will meet the well-made temporary, then the distribution of water using a bucket or using a hand pump manually. When the fire can be extinguished, then the well will be closed / capped with a stopper, generally by using a block of wood / redwood later called fireplug. Locations where fireplug will be marked for use at another time when there is a fire around the fireplug. This is why until today sometimes still called fireplug hydrant. Today, the fastest growing hydrant installations where the installation of hydrant used are standardized throughout the world complete with supporting equipment and accessories.

 How it works is a hose connected to the hydrant and valve is opened, it will issue a torrential flow of water with a relatively high pressure. The resulting water pressure at the end of the hose is 350 kPa (this also depends on the size of the hose and water source). This hose can also be connected with a fire engine and then can be connected to a pump with greater power to produce greater water pressure so that it can be divided into several channels. Hoses can also be connected using a connection that has a screw / drat. One important thing to note is the opening of the hydrant line. Where the right method of opening and closing the hydrant is done slowly. This is to avoid the phenomenon of water hammer which can damage the piping system and accessories installation of fire extinguishing systems.

Home Security Guide

By Darma Sentosa (17/6/2011)

Some guidance in conducting security and safety in the home through a home security is as follows:

1. Make sure your house is locked securely when you leave the house, besides that make sure the gas is also closed securely.
2. Install a fire suppression system at home so that in case of fire when leaving the house so the fire can be extinguished automatically.
3. Prevent the location of security system carried out in areas easily identified. The increased popularity of home security systems among people have seen a simultaneous improvement in techniques used by burglars to break into people’s homes.
4. Create a layered security system not only built up through the cable but can be through radio waves. Burglars of today have understood the working of the security systems, all they have do is snip the cable from the alarm system. 
5. Create an integrated security system so that wherever we are able to provide a report on the state of our house in real time.

It’s easy to discourage break-ins by just installing a home security system in your house. Though we can’t say a house that’s protected by a security system is exactly impenetrable, the chances of such a house being targeted by burglars are very less. Which can only be done is to take reasonable precautions as early as possible so we can have peace of mind for security of our homes.

Home Security Overview

Home security is about your safety and security system in your house. To protect from accesing your house and property from attacker. To give safety and security protection from thieves and intruder. Whenever you’re away or in particular when you is at residence, it provides you peace of mind when you know that your home is defended and sheltered against thieves and home breakers. We worth numerous things in our household which are worth protecting, principally your life and your family's. However crime occurs in all types of neighborhoods, it led homeowners to think more about how to secure their possessions and protect their families. Some have taken extreme measures. Others have implemented small changes to increase security. Therefore, we use a Home Security System.

Home security system is a collection of various tools used in detecting the threats that come to disturb security and safety at home so we can feel comfort in the home or leaving home. The equipment used can be either electronic or mechanical system that essentially can detect, report and deter exist threats. Examples of some home security system that can be used is:  

Alarm systems. This is what most homeowners consider when looking for an additional security measure. An alarm can protect a home while the residents are away or asleep. When an intruder enters, the alarm sounds. The homeowner is called as well as the police. Alarms are also available to warn residents about fire or the presence of carbon monoxide. But for an alarm to work the owners have to remember to set it. Many homeowners don’t set their alarms when they are home, making them vulnerable to home invasions. An interesting tidbit: Many homeowners don’t purchase an alarm system but place a sign in their yard indicating that the home is protected by a security system.

Lighting system. Thieves like to hide. If they strike at night they will likely run if a light comes on as they try to break into a home. Using good lighting throughout the room can provide a broad overview on the surrounding environment.

Motion detectors, which only come on when a person nears the home, are popular because they save electricity and will surprise a thief who thinks the home is an easy mark in the dark.

CCTV (Closed Circuit TV), can provide visualization through the integrated monitors in the house. This tool can be connected to motion detectors, lighting systems and alarms so that safeguards can be run in an integrated and automated.

Landscaping. High shrubs give thieves a place to hide while they try to crawl into your windows. Removing a favorite bush or replacing it with a smaller one to protect their home is a sacrifice many homeowners are willing to make.

Whether or not you will have a household security system or devices, it can be very best that we take precautions. Keep in mind, an ounce of prevention is better than a pound of cure. We need to watch out for our well-known mistakes due to the fact they can make your home an quick mark for thieves. Foremost, we neglect to fix broken locks correct away, putting the job off for tomorrow or whenever they feel like it. It's significant; however, to make sure all of your doors and windows have powerful modern locks that are in superior status Also, be sure that that all of the doors are properly shut just before leaving the home or going to sleep. Another frequent error will be the notion that hiding a key in locations like beneath a rock, beneath a doormat, in a potted plant, or above the door is safe for reasons that they're afraid they will lose their keys and lock themselves out. On the other hand, burglars completely know about all these commonly put to use hiding locations. Under no circumstances ought to you leave the key to your home. For those who often lose your keys or lock yourself out of the house, consider receiving a fingerprint or keypad door lock for your front door.
 

Home security is just a matter of popular sense as well as a sense of responsibility. If we are responsible for our actions, then we could conveniently keep away from any untoward incidents. Forethought and preventative measures is better.
