Smoke alarm for ship, alarm system and alarm methods thereof

Abstract

The invention discloses a smoke alarm for a ship. The smoke alarm comprises a remote second fire alarm controller which is used for controlling a cargo hold, wherein the remote second fire alarm controller is arranged in a CO2 chamber. The invention further discloses an alarm system of the smoke alarm for the ship. The alarm system further comprises a third fire alarm controller used for controlling a cabin and a first fire alarm controller used for controlling a living area, wherein the third fire alarm controller and the second fire alarm controller are connected with the first fire alarm controller. The invention further discloses an alarm method of the smoke alarm for the ship and an alarm method of the alarm system of the smoke alarm for the ship. According to the smoke alarm for theship, the alarm system and the alarm methods thereof, a first smoke detection box is placed in the safe cargo hold, so that the installation of a first sampling pipeline is not limited by space, the first smoke detection box can be connected to the first sampling pipeline with the pipe diameter of DN20-150, the first sampling pipeline is not prone to block, the air sucking amount is large, the airsuction is rapid, and the fire alarm response time is short.

Description

technical field [0001] The invention relates to a smoke alarm for ships, an alarm system and an alarm method thereof, belonging to the technical field of ship security. Background technique [0002] The Chinese patent with the application number 201410171698.3 and the authorized announcement number CN 104122369B discloses a smoke detection unit, a smoke detection system and a smoke detection device. The body corresponds exactly to the suction hose 3, the three-way valve and the fire hose 14, and thus to the cargo compartments 12, 13, 17, 18. In each individual housing there is a smoke detector". Due to the space limitation of the housing 4, there is a smaller housing in the housing 4 with a smaller size, and the smoke detector set in the smaller housing does not allow a large amount of air to pass through, so its suction hose 3 The diameter of the suction hose is generally within DN25, and the thinner suction hose 3 is prone to blockage and longer pumping time, and the prob...
