1 Configuration Description

1.1 System Introduction

System Composition

The container data center fire extinguishing system consists of the automatic fire alarm system, gas extinguishing equipment, and the control system.

The automatic fire alarm system consists of components including the heat detector, smoke detector, audible and visual alarm, alarm bell, gas release indicator, and the very early smoke detection apparatus (VESDA for short, able to detect and report fire alarms at an early stage).

The gas extinguishing equipment uses heptafluropropane as the extinguishing agent. It consists of components such as the extinguishing agent vessel, gas supply pipe, pressure annunciator, and solenoid valve driver.

The control system consists of the gas extinguishing controller and emergency start/abort switch.

Working Principles

When a fire occurs and generates smoke and heat, the smoke detector and the heat detector will be triggered and send fire alarm signals to the fire controller. Then the controller will generate a startup current to start the solenoid valve to open the storage valve, which will release the extinguishing agent to the protected zone. The automatic alarm system will send alarm signals at the same time.

Figure 1-1 shows the network diagram of the container data center fire extinguishing system. Table 1-1 lists the functions of the components in the fire extinguishing system.

Displays "DON'T ENTER WHILE RELEASING GAS" to warn onsite personnel in case of a fire and the fire extinguishing equipment releases the extinguishing agent into the protected zone.

Audible and visual alarm

Generates dazzling flash signals and shrill audible signals in case of a fire, reminding onsite personnel to evacuate from the site immediately, thereby avoiding major accident.

Emergency start/abort switch

Starts or stops the gas extinguishing equipment in case of a fire. The device is installed outside the door of the protected zone. If you press the glass plate to start extinguishing in emergency, the red indicator lights up.

Heat detector

Evenly deployed in the aisles inside containers to detect the temperature inside the containers in real time. When it works in monitoring mode, the red indicator blinks. When the ambient temperature exceeds the alarm threshold, it enters alarm mode and the red indicator is steady on.

Smoke detector

Evenly deployed in the aisles inside containers to detect the smoke density inside the containers in real time. When it works in monitoring mode, the red indicator blinks. When the onsite smoke density exceeds the alarm threshold, it enters alarm mode and the red indicator is steady on.

Alarm bell

Produces clear and consistent sounds in case of a fire, reminding onsite personnel to evacuate from the site immediately, thereby avoiding major accident.

System Features



All surface-mounted fire control cables are routed through metal hoses. The hose ends are protected with grommets to prevent damage in case of a fire. Fire control cables are routed and used separately which ensures secure and reliable power supplies to the fire extinguishing system.

VESDA

A VESDA consists of the host, power box, and sampling pipe. The VESDA host includes two types: VLS and VLP. The VLS is a four-pipe scanning detector that can monitor each pipe and generate alarms. The VLP is a standard detector that can only conduct general monitoring but not for each pipe. The host should be configured based on practical requirements.

The detector host consists of a suction pump, filter, high-sensitivity smoke detector, and precision electrical analyzer. The fan sucks air samples from the monitored environment through the air sampling pipe to the smoke detector, which will analyze and process the samples and calculate the amount of smoke in the air. If the smoke density exceeds the preset alarm threshold, the system blinks and sends alarm signals to the ECC.

A dedicated PPS-004 power box should be configured for the VESDA. The PPS-004 power box should be supplied by a 220 V AC main input and supplies 24 V DC power to the VESDA host. Backup batteries should be deployed for the PPS-004 power box.

The features of the VESDA are as follows:



High sensitivity and wide sensitivity adjustment range (0.005–20% obs/m), able to detect regular fires at an early stage as well as the particles generated by the softened insulation layer of an overloaded power cable

Active air sampling which uses the high-efficient air suction pump to continuously suck the air samples from the protected zone to the detection cell; detecting results less influenced by air flow compared with the traditional fire detection method



Small-sized and easy for installation; able to be deployed based on onsite requirements, adopting polyvinyl chloride (PVC) pipes that enable flexible installation such as on the ceiling, under the floor, at the air conditioner air return vents, and in the positions that require special protection, for example, inside the equipment cabinet through the capillary air sampling pipes to monitor the equipment in the cabinet.



Using a dedicated filter to process the air that will be used to clean the laser measuring cell, which prolongs the life span of the detector. The filter can be easily maintained and replaced, and cleaned by blowing the air sampling pipe. Therefore, you do not have to replace other components.



Improved self-diagnostic system that enables the monitoring of the VESDA system, network, and sampling pipe status in real-time; generating alarm signals and able to locate the faulty areas if a fault occurs

2 Operation Description

Issue 01 (2014-3-15)

Huawei Proprietary and Confidential

2.1 Precautions



Before commissioning the fire extinguishing system, ensure that all control cables to fire cylinder solenoid valves have been disconnected. This prevents the fire extinguishing equipment from malfunctioning due to improper manual operations or incorrect cable connections, and further prevents accidental damage. After the commissioning is complete, reconnect the solenoid valves.



To ensure the normal operation of the fire extinguishing system, the dowel tightening the solenoid valve and the container valve must be removed. To prevent the fire extinguishing system from spraying falsely when installing the IT equipment and commissioning the system, remove the dowel tightening the solenoid valve and the container valve on the fire cylinder only after you have commissioned the IT equipment and fire extinguishing system.



Before commissioning the system, perform the jumper operation for the passive output. Otherwise, the 6 A fuse (5D) on the main board will be damaged.



The main task involves commissioning of fire extinguishing association, which can be operated only by professionals in this field.



Only qualified personnel are allowed to perform the operation and maintenance (O&M) on the fire extinguishing system of the container data center.



Before performing routine maintenance of the fire extinguishing system, inform the related departments of the temporary downtime due to maintenance. In addition, disable the logical control function of the area or system to prevent false alarms. Inform the related departments of the system recovery after the maintenance is complete.



Take ESD measures before removing the front panel from the VESDA.



The following contents in this document describe the operation of a single-zone fire extinguishing system. If the container data center is configured with multiple single-zone fire extinguishing systems, perform the operation based on corresponding introductions in this document.
