How often should the system be checked?

System checkups should be made twice every month for appearance and pressure, and twice every year for a general checkup including device fastening and nozzle clearance.

AI-Powered supplier vetting

SummaryWofu Fire & Security Equipment Co., Ltd. is a China-based limited trading company established in 2013, offering fire-fighting, alarm, hardware, rescue, and road-safety products. The supplier reports flexible customization and participation in the Canton Fair, but no ODM service, no OEM service for popular brands, no new products in the past year, and no SDK. Service-management controls are weakly documented: no written procedures or records were reported for supplier assessment, corrective actions, or complaint handling. It has no overseas showroom, agents, or branches. Production-related information is inconsistent: one slice reports more than 10 production lines and 11–20 quality staff, while another identifies the company as a trading company with 3 employees and another reports 9 employees. No management-system certifications are listed. Financial evidence is incomplete and is excluded from this assessment in accordance with the privacy requirement.

Supplier typeThe supplier is identified consistently as a Trading Company and Limited Company, headquartered in Hunan, China. Its stated business covers wholesale and retail of fire-fighting equipment, electronic and hardware products, and rescue supplies, indicating a trading-oriented operating model rather than a clearly documented manufacturer profile.

CertificationsThe supplier management-system certification field is explicitly recorded as NIL. This is a stated absence of certification evidence, rather than merely incomplete documentation.

After-Sales capabilityThe business scope includes installation and after-sales service for security alarm systems, and the supplier reports one-month average lead times in both peak and off-season with several quotation and payment options. However, it reports no written procedures or records for service-capability assessment, corrective and preventive actions, or complaint handling, and has no overseas agents, branches, or showroom.

R&D capabilityThe supplier reports no new products during the past year, no ODM service, and no available SDK. These explicit limitations indicate weak documented innovation and development capability.

Customization capabilityThe supplier explicitly lists customization from samples, customization from designs, full customization, minor customization, and flexible customization. This provides direct evidence of broad stated customization coverage, although no supporting project examples or performance records are supplied.

Product Q&A

Q:What happens if there is no pressure display on the pressure switch?

First, check if the pressure switch is turned on. If it is on but shows no pressure, the switch may be malfunctioning and needs replacement. If a new switch still shows no pressure, there may be air leakage, requiring immediate refilling.

Q:Do I need to pull out the security pin before operating the system?

Yes, the security pin on the container valve must be pulled out before the cam handle can be pressed down for manual startup. Locking the cam handle does not affect nitrogen startup.

Q:Should the safety shield of the electromagnetic driving device be removed before operation?

Yes, before the system operates, the safety shield must be pulled out and the bolts on the electromagnet loosened and then fastened again. Otherwise, the electromagnetic valve cannot be opened.

Q:Are the leads of the electromagnetic valve and pressure switch polarized?

No, the two leads of the electromagnetic valve and the pressure switch are non-electropolar.

Q:How does the automatic startup mode work?

When smoke or temperature rises, detectors send a signal to the controller. After confirming the fire, the system waits 30 seconds, then activates the extinguisher and linkage signals like shutting down ventilation.
