How The Fire Detector Works

The fire detector is the most effective way to detect a fire in its early phase. Its ability to detect the fire in its initial phase allows it to take measures to control the fire, facilitate evacuation, and act on the extinguishing system. A fire detector is the fastest way to clear and evacuate the fire area.

 

Detection At Work

 

A simple spark on a computer can start a fire with disastrous consequences. A fire detector will warn of the incident in its initial phase, and everything will be in an unpleasant anecdote.

In the home

Although the use of fire detectors in homes is not compulsory, many countries consider family safety to be paramount, and they do require it, being able to opt for several systems, including the simplest, an autonomous detector that works with batteries.

The automatic fire detector

It is in charge of detecting the fire and activating the measures for its control. Automatically the detector, without the need for human intervention, carries out its surveillance function of the area it protects.

Detecting fire in an early stage is the key to minimizing its consequences. Statistics tell us that 3,000 people die each year, mainly because of the smoke produced during the fire.

Automatic detectors provide great security. They are the earliest fire detection equipment and will warn you through systems and associated visual indicators of the possible fire to proceed with the evacuation of the premises and activate the extinguishing equipment.

Operating sequence

 

  • It is activated in the presence of smoke, flame, or temperature increase depending on the installed sensor.
  • Sends a signal to the fire panel as soon as it is activated.
  • If the fire spreads, the detectors in the fire’s advance line are activated.
  • The fire station acts as a link with the evacuation, extinguishing system, fire brigade team, and others.
  • The fire panel can also be activated manually using buttons located on the premises in accordance with current regulations.

Maintenance

Like any other electronic equipment, detectors must undergo periodic maintenance and checking operations in accordance with current regulations. Given its detection mechanism, it is necessary to clean its internal chambers by specialized and certified personnel to guarantee correct detection.

Fire detectors are high-quality equipment, backed by quality standards.

Fire Detection System

Basics Of A Fire Protection System

Fire detection systems are very effective means of protecting people, facilities, equipment, property, and materials from the dangers of fire if they are installed, maintained, and used properly. The most well known of fire alarm protection companies use these very same systems. The technology related to these systems has evolved throughout its existence, and today, thanks to the advancement of technologies and the experience in their use, they have become an indispensable component when detecting a fire, especially in its phase. Initial, which is the most critical moment, where the fire can be more easily put down; On the other hand, late detection of the same that would delay the planned emergency actions, can cause large losses and exponentially increase the difficulty of extinguishing it.

The main function of a fire detection system is precisely to detect a fire as early as possible and generate the corresponding alarm signals in order to be able to take the appropriate extinguishing and evacuation measures. For this, the system must emit acoustic and / or visual signals both to the occupants of the building and to whoever is monitoring (on-site guardian, remote monitoring, etc.). Detection can be carried out automatically through the use of automatic detection equipment as well as by people using manual actuators, and in general, the systems have both warning modes. It is also important that the system can function satisfactorily, limiting the occurrence of false alarms.

Types of Fire Detection systems

We highlight the two main types of detection systems:

Conventional Systems: they work in a similar way to an intrusion system, with physical zones on the panel that allow the connection of multiple detectors (Maximum 25 per zone according to local regulations), reporting events for each zone of the panel.

Intelligent Systems: with more modern technology adapted to current needs and regulations, they work with communication loops (SLC) that, according to the central, can have a capacity for 50, 99, 127 or 159 devices, for example, and each one has a unique programmable address that allows Identification of each device separately in a shooting situation and the complete ones offer the possibility of receiving and adjusting specific parameters on each device remotely. Other notable functions are drift compensation (Auto-adjustment of smoke sensors) and automatic diagnostics of the state of the installation. Within this category, there are only Addressable and Analog Addressable systems that are the most complex.

Fire detection systems are critical when protecting a building, and its operation must be guaranteed at all times since not only the heritage but the human lives present in the establishment are being protected, an early warning can save lives and prevent tragedies as we have already seen happen in our country. The training of the integrator is essential so that they can provide good advice to the Client when designing a security solution; therefore, we invite you to join our online and face-to-face training for integrators in order to gain insight into these and other security solutions for the Security One hand.…

General Guidelines

Fire Detection: General Guidelines For Determining The Location And Spacing Of Detectors

In fire detection, the number and arrangement of detectors is a function of the type of detector, the geometry of the place to be protected, and the environment that prevails in the supervised room.

The choice of detector is made based on two basic premises:

Some fire protection regulations specify a separation distance between detector centers under ideal installation conditions of 9 m, considering smooth and unobstructed ceilings between the protected area and the detectors. Taking into account that most of the rooms are rectangular or square, placing a detector in the center of a room, it would be ideal for covering a diameter of 13m.

Since problems such as multi-level ceilings, exposed ceiling joists, storage spaces, and partitions that obstruct the passage of smoke to the detectors, air stratification, or sloping ceilings must be addressed in practice, the separation between detectors varies from according to each case.

It must also be considered that for the detector to be 100% effective, the maximum ceiling height must be 3 meters. At a higher height, such as 6 m, the effectiveness is reduced to 64%, so the distance between detectors must be shorter.

In sloped or gabled ceilings, the separation of detectors in the horizontal plane, taking as a reference the vertical plumb line of the top of the roof, must be 1 m from the said vertical line. These must not be less than 0.5 m. Furthermore, the horizontal and vertical distance between the detectors and the stored merchandise must not be less than 0.5 m.

Duct detectors and air conditioning systems are specially designed for this use, differ from those exposed so far, and must meet the standards to work with a certain airspeed within the space for which they are intended.

The manual fire alarms shall be grouped in such a way that the place of origin of the warning can be quickly and unequivocally determined. They will be mounted in a conspicuous manner along escape routes such as exits, corridors, stairs, and sectors especially exposed to dangers. They must keep a distance of not more than 40 m from each other.

The different aspects that must be taken into account for the correct implementation of a fire detection system have been briefly analyzed. But it is considered that the definitive project must take into account all the particularities of the place to be protected and of having been studied in all its details.
