Fire Alarm Device

Ion heat alarm:

This type of fire alarm detector releases ions from within the sensor, intercepting smoke from fires and sending a signal to the control panel to trigger a fire alarm. It is highly responsive to carbon smoke and does not respond to chemical smoke.

Optical fire alarm detector:

Optical fire alarm detectors are designed to detect slow-burning fires. The smoke that reaches the optical cell inside the sensor scatters the light, enabling it to send signals that help issue a fire warning. It is cost-effective but not sensitive to all types of smoke. It is commonly used in places with oil and grease.

Linear alarm detector:

This type of fire alarm device is used in high-traffic areas, such as malls. The smoke from the fire prevents contact between the transmitting and receiving devices in the sensor, facilitating fire detection.

Smoke heat detector:

One of the most common smoke detector types, it works similarly to the linear alarm detector. When a fire occurs, the smoke rises and interrupts the linear beam inside the sensor, triggering a fire alarm. It is used in places where smoke is not normally present.

Heat detector alarm:

This type of fire alarm device relies on infrared radiation and operates based on the temperature increase caused by a fire. It is used and installed in public places and comes in two types: high-temperature and fixed-temperature detectors.

Smoke and heat alarms

This type of fire alarm sensor is characterized by its expensive price and high efficiency in detecting fires, whether by detecting smoke or high temperatures, and is used in places with heavy smoke or steam.

Gas Detector:

This type of fire alarm sensor senses the presence of gas leakage in the air. It detects a decrease in oxygen levels in the area where a gas leak may occur, whether the gas is toxic or flammable. It is commonly used in fuel stations and gas pipeline warehouses.

Air Detector:

The best smart smoke detectors are used in air duct systems to detect fires within the air duct systems, such as in air conditioning systems. It is also used in radiation therapy rooms in hospitals, as regular detectors can be affected when directly exposed to radiation.

Specifications of smoke and heat alarms:

1. They can be powered by two wires with a DC voltage of 8-26 volts.
2. They operate efficiently at temperatures up to 80 metres.
3. They operate efficiently in humid conditions, up to 95%.
4. They can sense invisible gases.
5. The alarm detector should be moisture, dust, and damage resistant.
6. It should be replaceable with a sensitive heat detector alarm.
7. The radiation source power should not exceed 10 microns.

Fire alarm detector components:

1. Fire alarm sensor: This is the sensitive part that detects heat, smoke, or optical radiation. It is installed in a location where it monitors the occurrence of fire.
2. Control Circuit: It is an electronic ring fire alarm that receives signals from the sensor, analyzes them, and issues an alarm in case of fire detection.
3. Fire alarm device: It is a device that emits a loud sound or light to alert the user of a fire occurrence.
4. Power Source: This is a part that supplies the fire alarm detectors with the necessary power to operate, either through a battery or an electrical cable.
5. Sensor Enclosure: It is a cover that protects the sensor from damage or external factors that may affect it.

Smoke detector installation steps:

1. Identify suitable locations to install fire alarm devices, where fires can easily ignite.
2. Install mounting bases on ceilings or walls using screws and drills.
3. Connect the wires of the fire detectors to the central fire alarm devices.
4. Install appropriate fire alarm detectors on the mounting bases using special clips.
5. Test the fire alarm detector regularly to ensure proper functioning.

Coverage area of fire alarm detectors:

The coverage area of fire alarm detectors varies depending on the type of sensor, its design, and the size of the area in which it is installed. Most fire detectors cover a distance ranging from 6 to 12 meters in all directions. It is important to install fire detectors correctly according to the manufacturer’s specifications to ensure full coverage of the targeted area and prompt detection of any signs of fire.

Difference between heat detector alarms and smoke heat detectors:

• Heat detector alarms:

They operate when the temperature exceeds a certain level and are used to detect fires or temperature increases in buildings, factories, and other places. If the temperature rises, it immediately triggers an alarm signal.

• Smoke heat detectors:

They operate when there is smoke in the area and are used to detect fires in buildings and public places such as airports, hotels, and hospitals. They rely on detecting smoke particles in the air, and if there is dense smoke, they emit an alarm signal indicating the presence of danger.
