A hanging fire suppression system, also known as a suspended fire suppression system, is a fire protection system designed to detect and suppress fires in specific areas or rooms. It is typically installed in commercial and industrial settings where fire hazards are present, such as data centers, server rooms, electrical control rooms, or storage facilities. The system comprises the following key components:

1. Fire Detection System: Smoke detectors, heat detectors, and flame detectors are strategically positioned across the protected area to monitor for signs of fire.
2. Control Panel: The control panel serves as the primary command point. It gathers signals from the detectors and analyzes the data to determine whether a fire is present. When a fire is detected, the suppression procedure is initiated.
3. Suppression Agent: The suppression agent may vary based on the specific requirements and characteristics of the protected area. Common agents include water, foam, inert gases (such as nitrogen or argon), and clean agents (such as FM200 or Novec 1230). The type of fire, presence of sensitive equipment, and environmental factors are all taken into account when selecting a suppression agent.
4. Sprinkler System: A hanging fire suppression system may also incorporate a sprinkler system. Sprinkler heads positioned across the protected area are activated when a fire is detected, releasing water or other fire-suppression chemicals to control or extinguish the fire.
5. Pipe Network: A network of pipes is built throughout the protected area to distribute the suppression agent evenly, maximizing its efficiency.
6. Discharge Nozzles: Discharge nozzles are carefully positioned and attached to the piping network to provide optimal coverage, distributing the suppression agent in a predetermined pattern.
7. Control and Activation: The suppression system is activated when the control panel determines that a fire is present. This typically involves sounding an alarm to notify occupants and initiating the release of the suppression agent through the piping system and discharge nozzles. The control panel may also interface with other building systems, such as HVAC or access control, to assist fire response and evacuation operations.
8. Safety Features: To prevent unintentional discharge or system failure, hanging fire suppression systems are equipped with safety features such as pressure sensors, manual activation stations, and alarms to signal system status or errors.
9. Maintenance and Inspections: Regular maintenance and inspections are essential to ensure proper functioning. This includes checking the pressure and integrity of the piping network, testing the detection devices, and verifying the functionality of the control panel.

The design and installation of a hanging fire suppression system may vary depending on specific building requirements and local fire safety regulations. Consulting with a fire protection professional is recommended to ensure compliance and the most effective system for a particular application.

This system is suitable for protecting electronic computer rooms, data processing centers, telecommunications facilities, process control rooms, expensive medical equipment, industrial equipment, libraries, museums and art galleries, clean rooms, anechoic chambers, emergency power facilities, and flammable liquid storage areas.

It is also ideal for locations where fires are more likely to occur, such as ship engine rooms, cargo holds, rolling mills, printing presses, oil switches, oil-immersed transformers, melt impregnating tanks, and equipment used to dry large generators and pulverized coal into cement.

• Small but effective design
• Extremely simple installation
• Minimal space required for placement
• Hangs on the ceiling or wall
• Low cost for small protective zones

There are two different types of hanging FM200 fire suppression systems: the electromagnetic hanging type and the temperature-based hanging type. Their compositions differ slightly.

Composed of an FM200 cylinder, FM200 fire agent, pressure switch, solenoid actuator, container valve, and nozzle.

Composed of a temperature sensor, FM200 cylinder, FM200 fire agent, and nozzle.

A fire occurs → the smoke/heat detector detects the change and sends a signal to the control panel → the control panel receives the signal and activates the alarm bell to alert occupants to evacuate quickly → after receiving signals from both the smoke and heat detectors and a few seconds of delay, the control panel activates the fire extinguishing system.

A fire occurs → the internal temperature rises high enough to break the temperature sensor → the fire agent is released and sprays from the nozzle.
