Import Gsm Alarm & Fwt System S3524a — Buy in Bulk from Supplier in China

The GSM alarm & FWT system S3524A is a combined security alarm and fixed‑wireless‑terminal solution designed for residential and small‑office environments. It operates on the GSM tri‑band frequencies 900 MHz, 1800 MHz and 1900 MHz, with an optional quad‑band module that adds 850 MHz. The unit includes a 7.5 VDC/1.5 A power supply, a 2500 mAh lithium‑ion battery that provides roughly 12 hours of standby, and an LCD menu that displays all settings. Sensors communicate on 433 MHz and up to sixteen wireless sensors can be linked to the mainframe.

The system supports both wired and wireless sirens, a built‑in microphone for wiretap alerts, and a SOS button on the remote control for emergency calls. Typical alarm panels in this segment offer similar tri‑band GSM connectivity and battery capacities between 2000 mAh and 3000 mAh, which matches the S3524A’s specifications. The device can be powered from an external AC/DC adaptor or from its internal battery, and it operates from - 10 °C to +60 °C with relative humidity of 10‑90 % non‑condensing. Standard industry practice recommends installing the unit in a dry indoor location to protect the LCD and antenna.

End users such as homeowners, small business owners and property managers can program up to three SMS alarm numbers and five dial‑out numbers, and they may customise pre‑set messages via the keyboard. To activate the system a SIM card that supports Call‑ID is required, and the supplier does not publish minimum order quantities, so buyers should confirm MOQ directly. Shipping is typically arranged from Shenzhen, China, and the supplier’s response rate is currently 0 %, so importers should verify communication channels before placing an order. Payment terms and incoterms are not listed; interested parties should request a quotation and confirm lead times with the supplier.
