Abstract

The invention discloses a fire-fighting alarm device for rail transit. The device comprises a fire-fighting system, a sensing system and an emergency system; the fire-fighting system comprises a base,an alarm fixed at one side of the base, a box body fixed on the base, a fire-fighting door and a guardrail which are arranged at one side of the box body; the sensing system comprises a photosensitive device, a smoke sensor, a temperature sensor and a wireless signal transmitter which are all fixed at the upper end of the box body; and the emergency system comprises a group of storage batteries and emergency switch panels which are fixed at the other side of the box body. According to the fire-fighting alarm device for rail transit, the photosensitive device, the smoke sensor and the temperature sensor are combined for operation, so that the accuracy of the fire-fighting alarm device is improved to the maximum extent; and the storage batteries are adopted for emergency use, so that the reliability of the device is improved.

Description

technical field [0001] The invention relates to an alarm device, in particular to a fire alarm device for rail transit. Background technique [0002] Fire alarm device, also known as fire automatic alarm device, is composed of trigger device, fire alarm device, linkage output device and other auxiliary function devices. The physical quantity is converted into an electrical signal through the fire detector, transmitted to the fire alarm controller, and at the same time displays the location and time of the fire, so that people can detect the fire in time, and take effective measures in time to extinguish the initial fire and maximize the fire. Reducing the loss of life and property caused by fire is a powerful tool for people to fight against fire. But at present, the sensor of the fire alarm device for rail transit is single, which leads to low sensitivity and easily delays the fire. Contents of the invention [0003] Purpose of the invention: To provide a fire alarm dev...
