Import Gsm & Pstn Burglar Alarm System — Buy in Bulk from Supplier in China

The GSM & PSTN burglar alarm system combines telephone network (PSTN) and cellular (GSM) communication to deliver alarm notifications to designated phones or monitoring centres. Fujian Quanzhou Dong Ang Electronics Co., Ltd., based in the Economic & Technology Development Zone of Quanzhou, Fujian, China, supplies a wall‑mounted or embedded unit that weighs approximately 3 kg without battery and up to 6 kg with battery. The system incorporates a micro‑computer controller, LCD display and supports eight wireless zones plus eight hard‑wired zones, each with a reaction time of 50 ms to 750 ms.

Power is supplied from AC 220 V, with a maintenance‑free lead‑acid backup battery rated at DC 12 V 7 Ah. The GSM module operates on 900 MHz and 1800 MHz bands, while wireless sensors use a 315 MHz frequency. Voice recording capacity is 20 seconds (24‑segment), and the unit can store up to five alarm phone numbers and eight user codes. Typical industry practice for similar alarm panels includes IP65 enclosure rating and operating temperature between - 20 °C and +50 °C, which aligns with the system’s intended deployment in residential and commercial settings.

Buyers such as security installers, property managers and system integrators should confirm the exact zone layout, battery replacement interval and any required certifications before ordering. The listing notes neutral packaging and offers no fixed MOQ or lead‑time, so importers must request those details directly. Clarify preferred Incoterms, whether FOB or CIF, and verify payment conditions to ensure smooth transaction handling.
