Product Details

Cabinet type heptafluoropropane gas fire extinguishing device

1. Working principle

When the fire detector detects a fire, the fire signal is fed back to the alarm control device. The alarm control device controls the sound and light alarm, sends an evacuation alarm signal, and controls the linkage equipment. After a 30 second delay, the alarm control device outputs a starting electrical signal (DC24V, 1.5A) to the electromagnetic drive device of the cabinet type heptafluoropropane gas fire extinguishing device. The electromagnetic drive device acts, opens the fire extinguishing agent bottle group, and releases the heptafluoropropane fire extinguishing agent, The extinguishing agent is sprayed into the protected area through a nozzle to achieve the purpose of extinguishing the fire. When the high-pressure fire extinguishing agent flows through the pipeline, the microswitch in the signal feedback device closes, and the signal feedback device acts. The feedback electrical signal is sent to the alarm control device, indicating that the heptafluoropropane fire extinguishing agent has been sprayed.

2. Product characteristics and scope of application

The cabinet type heptafluoropropane gas fire extinguishing device does not need to be equipped with a dedicated bottle group room. The entire cabinet is set up in a protective area, suitable for small space protective areas such as computer rooms, archives, valuable items warehouses, communication rooms, etc. The combination of multiple cabinet type devices can also protect larger protective areas.

3.  Cabinet type device composition

The cabinet type device mainly consists of a cabinet body, a fire extinguishing agent bottle group, an electromagnetic drive device, a signal feedback device connecting pipe, and a nozzle, and is divided into two forms: single cabinet body and double cabinet body.
