l 100% Free Call Activation
Authorized users dial the SIM card number; the device rejects the call on the first ring and triggers the relay. No call charges, no monthly fees, no distance limits.
l 200 Authorized Users Management
Store up to 200 phone numbers. Add, check, or delete users via simple SMS commands. Ideal for communities, offices, farms, and multi‑user facilities.
l Secure Caller ID Verification
Only pre-approved numbers can activate the device. Unknown callers are ignored, preventing unauthorized access and signal cloning.
l Dual Control: Remote + Local
Control via free call, SMS commands, or a wired push button (local manual backup). Perfect for power outages or weak signal areas.
l Programmable Relay Timer
Set relay ON time from 0–999 seconds (default 1s) via SMS. Adjust for gates, doors, pumps, or machinery.
l Wide Voltage & Low Power
Operates on AC DC7-36V (12V/24V compatible), max 50mA, average 25mA. Low energy use, stable performance.
l Compact & Durable Design
Mini size (96.5×50×31.5mm), lightweight (88g), easy wall‑mount. Works reliably from ‑10°C to +60°C, 10–90% humidity. CE/RoHS/FCC certified.
How It Works
1.Insert a 3V Nano‑SIM (voice plan only, no data needed).

3.Add authorized numbers via SMS: 1234#TEL00XXXXX#001#.
4.Dial the SIM number from an authorized phone → free activation.
5.Use SMS for remote ON/OFF, status check, or user management.
