What Smoke and Gas Detectors Are in Stock at SUMRING’s Shenzhen Factory?

Smoke and gas detectors in stock are finished units listed in a manufacturer’s available inventory at a specific time, rather than products shown only in a catalog. For overseas distributors and project buyers, an inventory snapshot is a useful starting point for checking model availability, electrical configurations, and the next purchasing step.

SUMRING’s November 2026 Shenzhen factory inventory lists 2,368 units across 10 configurations and seven model numbers. The stock covers standalone smoke detectors, four-wire smoke detectors, combination CO and gas alarms, and combustible gas detectors. This is a dated factory inventory record, not a promise of immediate dispatch or availability in an overseas warehouse.

What Is Available in the November Factory Inventory?

The following smoke and gas detectors in stock were listed in SUMRING’s November 2026 factory report.

Stock Notice: SR-802-4 is a phase-out model. Its remaining inventory is available subject to confirmation, but production will not resume after stock depletion. All quantities reflect the November 2026 inventory snapshot.

These smoke and gas detectors in stock are grouped by model and configuration, not by carton size. Quantities reflect the November report. Every order requires a refreshed stock check, including quantities already allocated to other buyers.

Which Smoke Detector Models May Fit Your Procurement Plan?

Among the smoke and gas detectors in stock, SUMRING’s November 2026 inventory includes 1,173 smoke detection units across three models.

For current procurement inquiries, buyers can focus on the SR-803-5 standalone smoke detector (789 units) and SR-805-4 four-wire smoke detector (225 units). These two models account for 1,014 units in the inventory snapshot.

Important Product Availability Notice: The SR-802-4 four-wire smoke detector has 159 units remaining in the November inventory report. This model is being phased out and will not be manufactured or replenished once the remaining stock is sold. It is therefore not recommended for new projects requiring long-term repeat orders.

When evaluating smoke and gas detectors in stock, distributors and project contractors should confirm system compatibility, wiring requirements, power specifications, and applicable certifications. For projects previously using SR-802-4, contact SUMRING to discuss suitable alternatives based on technical requirements.

Which SR-918 Gas Detector Configurations Are Listed?

The remaining 1,195 units comprise 372 SR-918DSY combination gas detectors and 823 combustible gas detectors across the SR-918NC, SR-918NS, and SR-918NV variants.

A buyer searching for smoke and gas detectors in stock may need more than a model number. The inventory distinguishes EU and US plug versions for several SR-918 models, while SR-918NC is listed as a DC model without a display.

For combustible gas detector wholesale inquiries, confirm the target gas, power input, required outputs, plug format, labeling, and destination-market rules. SR-918 features can differ by variant; do not assume that one version’s display, CO sensing, or valve connectivity applies to every unit. See the SR-918 CO and Combustible Gas Detector technical overview for related specifications, then verify the exact stocked version.

How Should Overseas Buyers Check Ready Stock?

When assessing smoke and gas detectors in stock, a useful inquiry includes the required model, quantity, destination country, electrical standard, application, and shipping destination. Send any documentation or conformity requirements before requesting a final quotation.

The phrase smoke and gas detectors in stock describes a factory snapshot; it does not establish certification, local regulatory acceptance, reserved inventory, shipping terms, or a fixed lead time. OEM/ODM branding, packaging, or design changes may also require a separate production schedule rather than shipment from existing stock.

Distributors considering four-wire smoke detector bulk orders should first confirm system compatibility. For general residential smoke alarm selection and maintenance information, consult the U.S. Fire Administration’s smoke alarm guidance.
