An optical smoke detector or photo-electric alarm works on the light scattering principle. The sensor chamber checks for smoke particles after every 10 seconds with the help of a pulsed infrared LED beam. These smoke detectors indicate a fire in non-smoking zones. They are used widely by commercial and industrial buildings as a safety measure. A commercial smoke detector sends a signal to the fire control panel while household fire alarms give audible or visual alarm from the detector. Smoke detectors are disc-shaped set up in plastic enclosures. The process of smoke detection takes place either through ionization or the photoelectric process. The detectors can use either of the two sensing methods. Domestic smoke detectors are interlinked and if one of them detects smoke, all the alarms trigger altogether even if the household power has gone out. Smoke detectors are used mostly in hospitals, gyms, office buildings, industries, malls and commercial buildings. How do Optical Smoke Detectors work? Smoke detectors work by detecting smoke in the first few seconds of the incident and send the signal to the fire control alarm panel. The types of detectors vary depending on the indicated fire that they detect. It also depends on the detection principle. Smoke, heat and flame are three main indicators of fire. The process used for detecting smoke is based on the light- scattering principle. When there is fire, smoke particles enter the optical chamber of smoke detectors. The LED light refracts and scatters on a photodiode. Then, the optical smoke detector sends the fire alarm signal to the control panel.

A 22.5 kg CO2 fire extinguisher is typically used for fighting electrical fires or fires involving flammable liquids and gases. These extinguishers use carbon dioxide (CO2) as the fire suppression agent. Here are some key details about such extinguishers: Weight and Capacity: 22.5 kg refers to the weight of the CO2 gas stored in the fire extinguisher. This is a relatively large-sized extinguisher, often used in industrial settings or places with higher fire risks. Fire Class: CO2 extinguishers are effective for Class B (flammable liquids) and Class C (electrical fires). CO2 is non-conductive and doesn't leave residue, which makes it ideal for electrical and sensitive equipment. Discharge Time: A CO2 extinguisher with a 22.5 kg charge typically has a discharge time of around 45-60 seconds, depending on the pressure and nozzle design. Range: The typical range of a CO2 extinguisher is around 3-8 meters, depending on the specific model. Usage: CO2 extinguishers work by displacing oxygen around the fire, which suffocates the flames. The gas is also very cold when discharged, helping to cool the fire. Safety: While effective, CO2 extinguishers should be used in well-ventilated areas because CO2 can be hazardous in high concentrations. It's also important to avoid breathing in the gas directly, as it can lead to suffocation. If you are looking for a Lifeguard-branded 22.5 kg CO2 fire extinguisher, you might be referring to a specific brand or model. The name 'Lifeguard' may refer to a brand used in some industries or regions, typically known for safety equipment, but more specific details would be needed to identify the exact product.
