CDW-1T1B Smoke Sensor Probe
CDW-1T1B Smoke sensor is a vital safety device that plays a crucial role in protecting lives and property from the devastating effects of fires. It is designed to detect the presence of smoke, which is often the first sign of an impending fire. Utilizing either ionization or optical technology, or a combination of both, the sensor works by detecting changes in the environment caused by smoke particles. Ionization – based sensors use a radioactive source to ionize the air, and when smoke disrupts the ion flow, an alarm is triggered. Optical sensors, on the other hand, rely on light scattering. When smoke enters the sensor, it scatters light, which is then detected, prompting the alarm.

Application
◉Early Fire Detection for Occupant Safety
Fire can severely damage or destroy a house that contains family heirlooms, electronics, and furniture. Smoke sensors, when they detect smoke, can immediately alert homeowners, enabling the homeowners to call the fire department promptly. For example, in a two – story family house, a smoke sensor placed on each floor’s ceiling can quickly detect smoke from an incipient fire. If a fire starts in the basement due to an electrical short circuit, the smoke sensor on the first floor can detect the rising smoke. This early detection gives family members sufficient time to wake up (if the fire occurs at night), gather important items, and evacuate the building safely.
◉Protecting Valuables and the Structure
They also protect the building’s structure and valuable possessions. Fire can severely damage or destroy a house that contains family heirlooms, electronics, and furniture. Smoke sensors, when they detect smoke, can immediately alert homeowners, enabling the homeowners to call the fire department promptly. Firefighters can then arrive earlier to extinguish the fire, reducing the extent of damage to the property.
◉Office Spaces
In large office complexes, smoke sensors are installed throughout the building, including in individual offices, corridors, and break rooms. For instance, in a multi – tenant office building, if a fire starts in a small storage area due to a malfunctioning electrical appliance, the nearby smoke sensors will detect the smoke. The building’s fire alarm system, triggered by the sensors, will then alert all occupants. This enables employees to evacuate in an orderly manner, minimizing the risk of injury and loss of life. Additionally, early fire detection can prevent significant disruption to business operations because firefighters can contain the fire before it causes extensive damage to office equipment, important documents, and infrastructure.
◉Retail Stores
Retailers rely on smoke sensors to protect their inventory and customers. In a large department store, with rows of clothing racks, electronics displays, and crowded aisles, a fire can spread rapidly. Smoke sensors installed on the ceiling can detect smoke from a small fire, perhaps started by a discarded cigarette in a fitting room. The immediate alarm can prompt store staff to initiate an evacuation, protecting both shoppers and the store’s valuable merchandise.
◉Protecting Workers and Equipment
Industrial plants often deal with flammable materials and high – voltage equipment, making them more prone to fires. Smoke sensors are installed in areas where combustible substances are stored, such as in chemical storage tanks or warehouses storing flammable liquids. In a manufacturing plant that produces automotive parts using flammable solvents, if a leak occurs and a fire starts, the smoke sensors in the vicinity will detect it. This early warning not only gives workers time to evacuate but also allows the plant’s emergency response team to quickly deploy fire – fighting equipment, protecting expensive machinery and preventing a major industrial accident.
