Import Gsm Alarm System — Buy in Bulk from Supplier in China

The GSM alarm system offered by Shenzhen Secrui Co., Ltd. is a wireless security solution designed for residential and commercial premises. It operates on DC 9‑12 V and draws a standby current of 25 mA, rising to 450 mA during an alarm condition. The unit supports four wired zones and six wireless zones, each capable of connecting multiple sensors. Communication uses GSM900, GSM1800 and GSM1900 MHz bands and selectable RF frequencies of 315 MHz, 433 MHz, 868 MHz or 915 MHz.

The system incorporates an EEPROM module that preserves configuration data even after power loss, a feature commonly required for continuous security monitoring. A built‑in rechargeable backup battery switches on automatically when mains power fails, ensuring alarm functionality during outages. Voice reminders and password protection are provided to reduce false alarms, matching standard practices for electronic alarm controllers. The hardware is housed in a neutral‑coloured gift‑box, suitable for wholesale distribution.

Typical deployment locations include shops, offices, villas, residential estates, garages and warehouses, where remote SMS and voice alerts enhance response speed. The standard package contains one host unit, one magnetic door contact, one PIR sensor, two remote controllers, one siren, a power source, an antenna and a user manual, packed in a neutral box. Because the listing does not disclose minimum order quantity, payment terms or lead time, interested buyers should request these details directly from the supplier.
