Ping An Finance Center Landmark Building Fire Protection Solution

System Requirements Analysis
According to the trial version 4.2.2, clause 4, and 4.2.3, clause 9 of the "Building Fire Protection Facilities Installation Quality Inspection and Evaluation Regulations" (DB37/242-2008), the water level of the fire water pool and fire water tank should be displayed in the fire control room. Based on fire regulations, ensuring the full water level of the fire water pool and high-level fire water tank and remote monitoring in the fire control room is crucial. If the fire control room does not have a level indicator for the fire water pool and high-level fire water tank, there is a high risk of failing the building fire protection facilities installation quality inspection and acceptance according to the fire regulations. Therefore, it is necessary to monitor the real-time water level of the fire water pool and tank in the fire control room, which requires the use of the WH311 fire water tank level indicator.

System Overview
The WH311 level sensor probe is directly placed at the bottom of the user's fire water pool or tank. The WH6 fire-dedicated level indicator is installed in the fire control room. They are connected by a 2*1.5 square shielded cable to display the real-time water level. It also has a high and low level alarm system to ensure that the fire water level is always high.

Application Challenges:
1. Electromagnetic interference exists in the monitoring scene;
2. Requires stable and accurate product operation.

Solution Advantages:
  1. Provides a variety of product solutions to meet different operating conditions;
  2. Customizable products to meet complex operating conditions;
  3. Excellent product quality, high precision, high stability, and high protection level.

Project Description

Project Description
Ping An Finance Centre, a core landmark building in Shenzhen, covers a total area of 459,187 square meters and has 123 floors (118 above ground, 5 underground).

Customer Needs

The fire water pool and tank are far from the fire control room, and they all need to be centrally monitored in the fire control center with high and low level alarm functions. Unified display is required in the fire center, and high and low level alarm signals need to be directly connected to the fire host.

Solution

The fire contractor of Ping An Finance Centre chose to cooperate with Dongfang Wanhe Company. By using products such as the WH311 level sensor and the WH6 fire water pool dedicated level indicator, good results were achieved, overcoming project difficulties and realizing technological innovation in the real-time monitoring system for the water levels of three fire water pools. The high and low level alarm directly connects to the fire host alarm system, achieving linkage with the fire host and facilitating smooth passage of the fire acceptance! The fire water pool level display project needs to provide technical evaluation and confirmation for all kinds of component professionals involved in the project to ensure the feasibility of the design and technical solutions.

Needs Analysis:

According to the "Building Fire Protection Facilities Installation Quality Inspection and Evaluation Regulations", 4.2.2 clause 4, the fire water pool water level should be displayed in the fire control room, and 4.2.3 clause 9, the fire water tank water level should be displayed in the fire control room. Therefore, a WH311 dedicated fire level indicator needs to be installed in the fire control room.
