Heat & Photoelectric Smoke Detector
The device is a dual‑sensor heat and photoelectric smoke detector produced by Shenzhen Sumring Technology Co., Limited. It incorporates an instant test button for on‑site verification. The unit operates on a 9 V battery and triggers a fixed temperature alarm at 57 °C. When activated, a red LED flashes and an audible alarm sounds at approximately 85 dB. The smoke sensing element responds when the smoke concentration reaches 2.06 % per foot, covering a detection area of about 20 m². Both sound and visual signals are provided simultaneously for heightened alertness.
Photoelectric sensors are standard for detecting smoldering fires, typically offering a response time of 10 - 30 seconds under EN54‑7 criteria. Heat sensors complement this by reacting to rapid temperature rises, a common safety layer in mixed‑use environments. Industry practice recommends a battery life of at least three years, and devices are often supplied with a low‑battery warning indicator, as listed. The detector generally conforms to UL 217 and EN54‑7 standards, though certification should be confirmed with the supplier. Installation height normally ranges from 2.1 to 2.7 m above the floor to optimise detection coverage.
The detector is suitable for residential apartments, hotels, offices and small industrial premises. It is packed in bulk cartons, with the possibility of custom printing on the packaging upon request. The supplier does not disclose a minimum order quantity, so buyers should verify the required volume directly. Shipping terms, lead time and payment conditions are not specified in the listing and must be agreed with the supplier before contract. Potential importers should request test reports and compliance certificates to ensure the product meets local fire safety regulations.

Sourcing Heat & Photoelectric Smoke Detector from Shenzhen Sumring Technology Co., Limited - China Import Guide
Prior to ordering, ask the supplier for a recent type‑test report that confirms sensitivity, alarm sound level and battery performance. Verify that the detector meets the fire safety standards required in your target market and request any additional certification copies that may be needed for import clearance.
Clarify the incoterm, typical lead time and payment schedule with the supplier, as these details are not listed. Buyers often arrange FOB Shanghai or Shenzhen, with a common practice of 30 % T/T in advance and the balance against shipping documents. Confirm whether the units will be shipped on pallets and if any special handling is required for the electronic components.
Arrange a pre‑shipment inspection to check that the devices function correctly, the battery is installed, and the alarm indicators operate as described. Request the full packing list, CE or other conformity certificates, and a declaration of compliance with local electromagnetic compatibility (EMC) regulations. These documents will smooth customs clearance and ensure the product’s suitability for end‑users.
