GSM Quad Band Wireless Door Phone Access Control System
The problem with most intercom relay systems is that they often require a professional hardwired installation and only work with a single landline based home telephone. This door phone access control system uses GSM Quad Band technology for communication, allowing wireless communication not just to a landline based home telephone but to any landline based phone or cellular phone as well. Additionally, this device is flexible enough to work for home or commercial applications as up to 263 subscribers can be registered with the system. Each subscriber is given a unique subscriber number (from one to six digits) with two different phone numbers to answer a visitor’s call. This plug-in device can be wall-mounted or flush-mounted, as it is built of a rugged, weather-resistant aluminum alloy exterior casing, ideal for outdoor installations.
This access control system can be connected to a electronic door strike/lock as well as a single or double automatic gate opener, each sold separately. When a visitor arrives at your property, they simply dial the subscriber they are trying to reach, and whether or not that subscriber is on site, at the office, or on vacation halfway around the world, they will be able to grant access and unlock the door or open the gate at the press of a button. The unit features a full size keypad and a large LCD display for easy programming by the system manager and easy operation by visitors. The system manager can set three emergency phone numbers and enable or disable subscriber functions.
