Look! on average, almost seven out of ten deaths are caused by smoke inhalation, and at night, you don’t even notice it. And one of the things that these devices do well in the event of a fire in the home is to detect smoke or heat in its initial phase.

Within emergency systems, there are two methods to detect a fire (initial phase of the presence of smoke or heat – flame): an automatic fire system and a second one, which is a manual activation:

The question is… What are the most common thermal detectors? Although manufacturers are always coming up with new technologies, we generally find the following types of fire alarm in stores:

Beware! We are not talking about gas detectors for when there are anomalies in; methane, propane, butane or those that detect the abnormal presence of carbon monoxide (CO) in the air they are different devices! Although we have manufacturers that offer us in the same element, a CO Detector + Smoke Detector.

What is a fire alarm

Gas detectors can be connected to the mains. Some models also incorporate a battery-operated battery so that they do not stop working in the event of a power failure. They are also available wireless. In addition, you should know that carbon monoxide detectors have a chemical that helps the detection process so you should check it as well as the batteries.

In this article we focus on the location of the detectors for maximum efficiency. Detectors should preferably be installed on the ceiling, in a fixed position, in a place where their performance is efficient, taking into account that smoke always tends to rise. A separation distance of 9 meters (in an unobstructed space between the area to be protected and the detector) can be established between one detector and another.

The detectors should be placed in the center of the ceiling of the room, as this is where smoke and heat are concentrated. Respect a minimum distance of 50 cm between the location of the smoke detector on the ceiling and the wall.

Fire alarms can prevent a fire before it can spread. There are different types of alarms with corresponding smoke, gas or temperature rise detectors. We tell you everything you need to know about fire alarms.

You can hire a fire alarm as part of a security pack from an alarm company or as an independent element. This distinction will mark to a great extent the security and effectiveness of the device.

This activation causes an action in the alarm device that can be from the emission of sound to alert the people in the building or the neighbors of the danger, to a call to an emergency service.

Domestic and work fires can originate at any time and, although there are certain mandatory safety measures in case of fire, such as the installation of fire extinguishers or emergency exits, being able to prevent them is essential.

The best system for fire prevention is a security alarm. Throughout this article we will explain the different alarms that exist to detect a fire and which one is the most advisable for each type of property.

Smoke detector features

The location of the detectors (on the ceiling or directly on the lintel) depends, among other things, on the distance between the upper edge of the door and the ceiling, as well as the type of fire protection closure.

If, for example, the opening width is more than 4 m but less than 8 m, twice as many lintel and ceiling detectors must be installed. The distance between the individual detectors should not exceed 4 m (13 ft).

Heat detectors should be used only in case smoke or dust is produced during the normal working or manufacturing operation process, so that there is a risk of smoke detectors triggering false alarms.
