How to choose smoke and gas detectors

Smoke and gas sensors are very useful to prevent problems in the home. They warn any leaks that may occur, or detect smoke warning of a possible fire. Gas detectors, can identify various types (butane, methane or natural) as well as emissions reaching dangerous levels, so if you’re thinking about installing one, will be a very useful tool for your peace of mind.

Optical smoke detectors

It is a safety equipment that emits a signal when it detects an abnormal level of smoke in the air. Optical are called because they incorporate a lens that detects visible smoke, either by the darkening of the air or by its dispersion. In this way, you can find two types:

infrared Ray are composed of a transmitter device and another receiver. When the space between them because of the smoke darkens, the receiver receives a very small fraction of the transmitter light, causing the alarm.

point type, that transmitter and receiver are accommodated in the same camera but separated by a screen. This means that when smoke enters the Chamber, it refracts a beam of light to the receiver and the alarm is activated.

Features

These devices have a fixed installation on the ceiling, place in which its performance is more efficient since the smoke always tends to rise.

The alarm that emits this type of detectors is acoustic. When they confirm the presence of smoke in a space they emit a sound signal which quickly warns of a possible danger.
Domestic detectors often work with alkaline batteries, although they can also be connected to the electrical system. Even in the so-called smart homes, connects to the central system of home automation.

Ones that work with batteries have the added danger of stop working when they are exhausted, tend to emit a signal which warns that the battery power is low.

They usually incorporate a light bulb that indicates its operation while it stays on. The latest models include bulb type LED, more efficient and much higher than the normal duration.
If you want to get maximum efficiency it is recommended to install one in each room of the House, or in those where you want a greater vigilance, or caution.

Sizes vary depending on the model and you have many classes which they pass unnoticed in the places that you decide to install them.

Recommendations to keep your smoke detector

The maintenance of this equipment is simple. You will only have to follow the recommendations to work always on the verge.

First, check the batteries in your smoke detector every 6 months. Although the appliance warns with a sign that the battery is exhausted you battery, is more to monitor from time to time that it is loaded.

Detectors should be cleaned on a regular basis, since they can collect dust, waste and even hair on your camera. Do not remove this dirt, may cause it to jump the acoustic signal for no reason.

It is important to have in mind the directive for this type of products. Make sure that you have the certificate in 54 of detection and fire alarm systems. It is required to meet this standard for fire detectors and the certificate must be renewed annually.

Where to place your smoke detector?

If your home has more than one plant, it is recommended to install a detector on each floor. It is recommended to place it in the living room or dining room, close to the kitchen and in hallways and landings. This way you can make sure that the acoustic signal is audible from every room of your home. However, also installed smoke detectors on the way out of the House is very useful in case of fire, because you can orientate yourself on the clear path to exit.

To avoid the alarm goes off for no reason, it seeks to prevent the installation of these devices in areas which generates steam, such as the bathroom or kitchen. Put it too close to radiators, heating or ventilation openings subtracted you the detector efficiency because they can dispel the first signs of smoke generated. Try also, place it at least to 30 centimeters of lamps, since the heat generated will favour the appearance of particles that get dirty the detector.

Gas detectors

It is a device that detects the presence of gas in the atmosphere and, when detected a high concentration in the air, active between a visual or audible alarm. Some allow even the connection to the gas system to turn off automatically when the levels are higher than normal. They are a very useful safety equipment to keep quiet before escaping.

Features

They are devices that work connected to the electrical grid and its installation is fixed. Placed in the ceiling, like smoke detectors, because it is the most effective place for to work to the best performance.

They can detect various types of gases, such as methane, propane and butane. If the gas concentration in the atmosphere is between 3% and 20%, the alarm will trigger. When the gas concentration reaches the level of risk the active device an alarm and an LED that will alert you of the danger.

Some models also detected the abnormal presence of carbon monoxide in the air, which you would be very useful to detect bad burning if you have stoves wood burning, gas, fireplaces etc.

Depending on the model, they vary the dimensions and layout. They are fairly discrete devices, so you can do that they may pass unnoticed in your home.

What to do when you jump the smoke detector alarm.

If you skip the smoke detector alarm, the first thing you should do is call the fire department or to the emergency room.

Provided that you do not put your safety at risk, it tries to close the door of the room in which a fire.

Do not ever open a door closed in which notes heat, there could be fire in the room and opened the door, run the risk of burns.

Soak a cloth or towel with water and cover the mouth and nose to avoid inhaling smoke.

The wisest is Crouching on the ground, because the temperature is lower, and toxic gases and smoke always tend to rise.
