Make Sure Your Smoke Detector is Mounted In The Right Place Of Your Home


Glad that you make a decision to use smoke detector or smoke alarm to protect you and your family. Smoke detectors are quite effective in warning unexpected fire if used correctly and properly. Do you familiar with the common sense and mount tricks, if not, and then this article is for you.

Mounting a smoke detector can be tricky. It is not just a matter of location, but also involves the type of detector, the surrounding home decors and electronics.

Some common senses. First of all, mount them at high places. Remember that smoke rises, it they don't reach the alarm, you can never heard the warning. Smoke alarms are simply screwed into the ceilings and should be fitted as close to the center of the room as possible, but at least 30 centimeters (12 inches) away from any wall or light fitting. Second of all, avoid mounting smoke detectors near windows or doors, where smoke can escape before reaching the detector. You should always make sure that your alarm is fitted in a place where it can be heard throughout your home - particularly when you are asleep.

How many room your house have? For maximum protection an alarm should be fitted in every room (except kitchen, bathroom) you should choose the type most suited to the risk in each room. For minimum protection the number to be fitted will depend on the type of home you live in. If your home is on one floor, you should fit the alarm in the hallway between the living and sleeping areas. If your home has more than one floor, at least one alarm should be fitted on each level. In this case a combination of optical and ionization alarms, preferably interconnected, will give the best protection.

What type of the smoke detector you get? Both ionization and photoelectric detectors are effective smoke sensors. Both types of smoke detectors must pass the same test to be certified as UL smoke detectors. Ionization detectors respond more quickly to flaming fires with smaller combustion particles; photoelectric detectors respond more quickly to smoldering fires. In either type of detector, steam or high humidity can lead to condensation on the circuit board and sensor, causing the alarm to sound. Ionization detectors are less expensive than photoelectric detectors, but some users purposely disable them because they are more likely to sound an alarm from normal cooking due to their sensitivity to minute smoke particles. However, ionization detectors have a degree of built-in security not inherent to photoelectric detectors.

What are the other appliances in your room? If you have a TV or other large electrical appliance in your bedroom, you should fit a smoke alarm there.




Some tips about mounting smoke detector or smoke alarm Include referring to your technician's advice and help, following the instruction, and getting reliable source for the product. Sourcingmap provides qualified products and services all the time.

How to Choose the Best Natural Gas Detector For Your Home


Do you use natural gas in your home for your appliances or for heating your water? Then you probably already know that you need a natural gas detector. While natural gas is a safe and eco-friendly fuel, leaks can and do happen...and that can lead to explosions, illness, and in extreme cases even death. Here are some factors you should consider before you choose a natural gas detector.

Natural gas is most often composed mainly of methane gas. Methane is highly flammable. If you're like most people, you associate methane with that distinctive rotten egg smell. But did you know that smell is actually added in? Methane has no odor at all, so the smell is put in as a way to signal you of a leak. Of course, if you have a cold or are asleep, that nasty smell may not be enough to alert you to a problem.

A natural gas detector is the best way to make sure that you are protected from leaks, but it's important to choose the right one. Find out how sensitive the detector is to other chemicals, or if it can be triggered by humidity. If so, you will need to take that into account when you install it.

Next, you want to know what the Lower Explosive Limit, or LEL, of the detector is. This refers to the concentration of natural gas required to trigger the alarm. If 100% means an explosion, an LEL of 20% means that the gas only has to accumulate to 20% of its LEL in order to set the alarm off. This gives you plenty of time to take action before things get dangerous.

You want to be certain that you can hear the alarm from anywhere in your house. Many natural gas detectors use a loud noise, so if you have a hearing impairment you may want to choose one that incorporates flashing lights as well. If you have multiple sources of natural gas that are not close together, you may want to get a natural gas detector that comes with more than one sensor. You can place the sensors close to the gas source, and mount the alarm in a central location.

You will need to perform some basic maintenance on your gas detector. If it has batteries, or relies on a battery back-up in case of power outages, find out how often you should test them, and whether there is a test button on the detector to do so. Also ask if the detector has an alert system to let you know if the batteries need replacing.

Also find out how long the sensors are expected to last, and if there is any warning in place that will let you know they are wearing out. If you can, find a unit with replaceable sensors, or else you will have to purchase a new detector when the old sensors no longer work properly. If the detector needs to be calibrated, ask where and how regularly this needs doing, and how much it will cost.




There is a lot to look out for when trying to make your home secure and safe. There are many hidden dangers to be aware of.

There is one thing for certain, the more information you have, the more informed your decision will be when buying a natural gas detector.
