II. Working principle 

Fire signals are detected by the fire alarm control panel or the gas‑extinguishing control system. Upon detection of a fire, an activation signal is sent to the suspended aerosol fire‑extinguishing device. Upon receiving this signal, the device’s internal extinguishing agent is activated, rapidly generating a nano‑scale aerosol extinguishing agent that is discharged to achieve rapid fire suppression.

Square Thermal Aerosol Fire Extinguishing Device | Frequently Asked Questions

Q1: What types of premises are suitable for suspended-type heptafluoropropane fire suppression systems?

A1: Suitable for enclosed spaces such as computer rooms, distribution rooms, energy storage cabinets, archives, and small high- and low-voltage switchgear; effective for extinguishing electrical fires. Not suitable for areas with sustained open flames, highly corrosive environments, or flammable and explosive dust.

Q2: Does a suspended-type heptafluoropropane system require a separate cylinder room?

A2: No, it is not required. The unit is directly suspended beneath the ceiling of the protected area, with no separate cylinder room, and occupies minimal installation space, making it ideal for rooms with limited space.

Q3: How long is the shelf life of heptafluoropropane extinguishing agent? How often must the cylinders be inspected?

A3: The agent itself is not easily decomposed and can be used for 5 years under normal operating conditions; cylinders are subjected to hydrostatic testing every 3 years in accordance with regulations, and may continue to be used if they pass the inspection upon expiration.

Q4: When a fire suppression discharge occurs, can personnel remain inside the protected area?

A4: No. Upon receiving a fire alarm signal, the system initiates a delayed discharge (typically 0–30 seconds), during which personnel must evacuate. After the extinguishing agent is discharged, the oxygen level inside the compartment drops; no personnel are permitted to remain.

Q5: How many activation methods are available for suspended-type heptafluoropropane systems?

A5: Typically, it is equipped with three types of start-up mechanisms: electromagnetic automatic start-up, manual on-site start-up, and mechanical emergency manual start-up, all of which comply with fire safety regulations.

Q6: Will openings in the protected area (such as gaps around doors and windows) affect the fire suppression effectiveness?

A6: Yes. During fire suppression, the doors and windows of the protected area, as well as ventilation ducts, must close automatically; if openings are too large, the extinguishing agent can easily escape, making it impossible to maintain the design extinguishing concentration and increasing the risk of fire‑suppression failure.

Q7: Will the equipment be damaged after a heptafluoropropane discharge?

A7: Heptafluoropropane is a clean agent with no residue; after discharge, it does not corrode electrical equipment, and the equipment can be put back into service once ventilation has been completed following fire suppression.

Q8: Are there any load-bearing requirements for equipment lifting?

A8: Yes. The floor slab at the lifting location and the load-bearing capacity of the lifting points must exceed the total weight of the equipment; structural load-bearing capacity must be verified prior to installation, and installation must be carried out by qualified personnel.

Q9: Can the heptafluoropropane agent be disassembled, reassembled, and refilled independently?

A9: No, it is not permitted. Refilling, maintenance, and dismantling must be performed by an organization holding the requisite fire‑safety qualifications. Unauthorized disassembly or reassembly will render the system inoperable and constitute a violation of fire‑safety regulations.

Q10: What routine inspections are required for a suspended-type heptafluoropropane fire suppression system?

A10: Routinely check that the pressure gauge is within the green normal range, inspect the cylinder for rust and the piping for deformation, and verify the status of the alarm control panel; arrange for a qualified maintenance provider to perform annual inspections.
