七氟丙烷设有气体灭火系统的保护区须配备火灾自动报警系统，其设计为现行标准设计规范，须符合探测器。下面
川消小编为您讲解一个问题--七氟丙烷气体灭火系统的报警系统设计要求。
The protection area with heptafluoropropane gas fire extinguishing system must be equipped with automatic fire alarm system, which is designed according to the current national standard design specification and must comply with the detector. Next, the editor of Sichuan Fire Fighting Company will explain a problem -- the design requirements for the alarm system of the heptafluoropropane gas fire extinguishing system.
系统控制和操作须满足特定要求，以便在发生火灾时能够及时可靠地启动系统。灭火系统须具备自动控制、手动控制和机械应急操作三种启动方式。预制灭火系统须配备自动和手动控制。手动操作装置应位于易于操作的保护区外，所有系统启动操作应能在一处完成。就地灭火系统的手动操作装置应位于保护目标附近。
The system control and operation must meet specific requirements, so that the system can be started timely and reliably in case of fire. The fire extinguishing system must have three starting modes: automatic control, manual control and mechanical emergency operation. The prefabricated fire extinguishing system shall be equipped with automatic and manual control. The manual operation device shall be located outside the protection area that is easy to operate, and all system startup operations shall be completed in one place. The manual operation device of the local fire extinguishing system shall be located near the protection target.
七氟丙烷气体灭火系统的保护区或保护区通常是防火的重要部分或可能是空的区域。即使人多的情况下，要在狭小的空间深处找到一把火，也并非易事。因此，一般需要自动控制，以便在发生火灾时能够迅速扑灭火灾。但是，系统还须同时具有手动控制，因为自动控制可能会失败。手动控制应该对火不敏感，并且通常在保护区外或远离保护区进行。
The protected area or protected area of heptafluoropropane gas fire extinguishing system is usually an important part of fire prevention or may be empty area. Even if there are many people, it is not easy to find a fire in a narrow space. Therefore, automatic control is generally required to quickly extinguish the fire in case of fire. However, the system must also have manual control, because automatic control may fail. Manual control should be insensitive to fire, and is usually carried out outside or away from the protected area.
为了使灭火系统快速启动，整个系统须通过单一控制进行操作。考虑到自动和手动控制同时失效（包括停电），系统须具有紧急手动启动模式。紧急控制通常是机械的。储存容器中瓶头阀的按钮和操作杆，应急操作可以是直接手动操作，也可以使用系统压力或钢索装置进行操作。
In order to make the fire extinguishing system start quickly, the whole system must be operated through a single control. Considering the simultaneous failure of automatic and manual control (including power failure), the system must have emergency manual start mode. Emergency control is usually mechanical. The emergency operation of the button and operating lever of the bottle head valve in the storage container can be direct manual operation, or it can be operated by using the system pressure or wire rope device.
二氧化碳灭火系统机械应急操作的手动操作推拉力不应超过178N。机械应急操作装置应置于储瓶或保护区疏散出口门外便于操作的位置。
The manual operation push and pull force of mechanical emergency operation of carbon dioxide fire extinguishing system shall not exceed 178N. The mechanical emergency operation device shall be placed outside the evacuation exit of the bottle storage or protection area for easy operation.
七氟丙烷气体采用自动控制启动方式时，需要30秒内可控延时注入，视人员撤离保护区的需要而定。对于平时无人作业的保护区，设置为非延时。
When heptafluoropropane gas is automatically controlled and started, it needs to be injected with a controlled delay of 30 seconds, depending on the need for personnel to safely evacuate from the protection area. For the protection area where no one works at ordinary times, it is set as non-delay.
When personnel enter the protection area, the fire extinguishing system can be switched to manual control mode, and when personnel leave, the automatic control mode can be restored. Manual and automatic control status display devices must be installed inside and outside the protection zone.
