The Connect2Go UNO security panel is a powerful TCP-IP-based security system, with the expandability to handle any sized system, all controlled from an intuitive, user-friendly App. Because the UNO is an Internet-based security system, you no longer need a phone line for your security system to send alarms to the central station or alerts to you or your contact's smartphone. PowerSeries high-quality, slim-profile keypads achieve a clean, unobtrusive look that homeowners and installers will appreciate for their easy programming and installation. The keypads feature an input / output terminal that can be programmed to operate as a zone input, programmable output or as a low-temperature sensor. The keypads also include adjustable backlit keys that address low-light situations and five programmable keys for simple one-button activation of system functions.
