They play an important role in enhancing people's fire awareness and improving the success rate of escape.
[0003] Because smoke usually floats upward, smoke fire alarm devices are usually installed on the ceiling of the building. This makes it difficult for personnel to operate and maintain them in the later stage. Most people of high height can only make simple touches with their fingers, even if they operate by raising themselves up with a stool. They are unable to perform more complicated operations such as disassembly or assembly or cancel false alarms, causing inconvenience in long-term use and maintenance.
[0004] The existing smoke fire alarm mechanism is assembled at a high position, which makes it difficult for personnel to operate when the alarm is accidentally triggered or maintained, resulting in the inconvenience of using the fire alarm mechanism. Therefore, a telescopic fire alarm device is proposed to provide a telescopic fire alarm mechanism for the interior of the building, which increases the convenience of use for personnel and reduces the difficulty of later operation and maintenance of the fire alarm mechanism.
