Product Description
Commtel Optimus E3K - 3 Button 4G GSM Audio Intercom With Keypad
The Optimus E3K is a high-performance, wireless GSM intercom designed to provide secure, flexible access control for multi-unit properties, shared driveways, or small commercial offices. By utilizing mobile network technology, the E3K eliminates the need for expensive, complex internal wiring, allowing you to manage your gates or doors from anywhere in the world.
Whether you are at home, at work, or on vacation, the Optimus E3K ensures you never miss a visitor.
Traditional wired intercoms require expensive groundworks and cabling that can fail over time. The Optimus E3K bypasses these hurdles entirely. It is the ideal "fit-and-forget" solution for installers and a seamless, high-tech experience for residents.
Please note this device requires a Nano SIM card (not included) to connect to the 4G network.
Product Features
- 3-Button Configuration: Perfectly suited for duplexes, shared gates, or small business blocks. Each button can be programmed to call up to three different phone numbers (Primary, Divert 1, and Divert 2).
- True Wireless Freedom: No range limits. Because it uses a SIM card, the intercom calls your mobile or landline directly. If the first number doesn't answer, it automatically rolls over to the next.
- Remote Access Control: Grant entry to visitors simply by pressing a key on your phone's keypad during a call.
- Authorized Dial-to-Open: Store up to 100 known phone numbers that can trigger the gate or door for free simply by calling the SIM card—no call charges incurred.
- Vandal-Resistant Design: Built to last with a robust, brushed stainless steel faceplate and back-lit buttons for easy nighttime operation.
- SMS Programming: Effortlessly update phone numbers and settings via simple SMS commands or a dedicated smartphone app.
Technical Specifications
- Power Supply: 12V 1A DC PSU fitted with a 3A fuse (supplied with the intercom).
