Fire Alarm Price, 4 Wires Smoke Detector
The SR-812PC-4 is a four‑wire smoke detector designed for ceiling mounting in fire alarm networks. It operates from a DC supply of 9 V to 35 V, matching the voltage range of most commercial panels. The unit draws a static current of 13 mA in the normally‑closed (NC) state and 4 mA in the normally‑open (NO) state. When an alarm condition occurs it supplies 9 mA (NC) or 19 mA (NO) to the relay output. Sensitivity is rated at 2.06 % ft ± 1.3 % ft, which aligns with typical indoor smoke detection requirements. Physical dimensions are listed as 100 mm length, a compact size for ceiling mounting.
The device uses a photoelectric sensing chamber, a common technology that offers reliable detection of smoldering fires while reducing false alarms from steam. Its relay output provides a straightforward dry‑contact interface that can be wired into existing fire panels without additional signal conditioning. Typical industry practice pairs such detectors with a 10‑year battery backup, although this unit’s specifications do not detail a built‑in power source.
The detector is appropriate for hotels, office blocks and residential complexes where ceiling‑mounted smoke monitoring is required. Importers should confirm minimum order quantities and any required CE or local certifications with Shenzhen Sumring Technology Co., Limited before finalising the purchase.

Sourcing Fire Alarm Price, 4 Wires Smoke Detector from Shenzhen Sumring Technology Co., Limited - China Import Guide
Before placing an order, importers should verify that the detector complies with any local fire‑safety regulations and confirm the presence of CE or other required certifications. Request a product data sheet that includes the exact dimensions, weight and packaging details to avoid surprises during shipping.
Logistics for this product are typically arranged on FOB or CIF terms; however, the supplier has not published lead‑time or payment‑term information, so buyers must ask for estimated production lead‑time and acceptable payment methods such as T/T or LC. Confirm the port of loading in Shenzhen and whether the supplier can consolidate shipments to reduce freight costs.
Because the supplier’s response rate is currently zero, arrange a pre‑shipment inspection with a third‑party agency to check the detector’s electrical performance, sensitivity and relay operation. Ensure the inspection report includes verification of the stated voltage range and current specifications, as well as a check for any visible defects before the goods are released.
