The Sumring Company offers the SR-812DC-2 fire alarm, a 2‑wire network photoelectric smoke and heat detector. It features a non‑polar power input, infrared photoelectric sensor, MCU‑based signal processing, network status LED, SMT construction, dust‑proof and moth‑proof housing, stainless‑steel shield, and anti‑RFI protection rated at 20 V/m‑1 GHz. The device complies with GB4715, EN54‑7 and UL539 standards.
The stainless‑steel chamber provides resistance to corrosion and electromagnetic interference, while the infrared sensor delivers reliable detection of both smoke particles and rapid temperature rise. In the fire‑alarm market, similar networked detectors typically operate on 12‑24 V DC, have a sensitivity of around 0.1 % / m³, and meet a response time of less than 30 seconds. The SR‑812DC‑2’s SMT manufacturing contributes to consistent performance across large installations.
The unit is suited for commercial buildings, industrial plants and high‑rise residential blocks where centralized monitoring is required. Buyers such as facility managers, construction contractors and safety integrators often request bulk packaging in anti‑static trays and specify Incoterms FOB Shenzhen. The Sumring Company can arrange sample dispatch and discusses payment after order confirmation.
