Aico 3000 Carbon Monoxide Alarm has a high performance, proven electrochemical sensor (10-year life) to sense CO presence. The sensor is individually calibrated and tested in CO gas to ensure accuracy. In alarm, the flash rate of the red LED indicates the level of CO detected. CO Alarm contains AudioLINK technology, which allows you to extract real time data from the alarm using its sounder directly to a smartphone or tablet via an App. A simple to read report is generated displaying details such as activation dates, sensor status and alarm life, that can be emailed to help form part of property records. CO Alarm is SmartLINK compatible, simply plug in an Ei3000MRF module for wireless interconnection, data extraction and real-time notifications of alarm activations and events via the SmartLINK Gateway and Portal. CO Alarm is fully compatible with all other Aico alarms and accessories whether a system needs upgrading or an existing system needs expanding; and works with either hard-wired, RadioLINK or hybrid interconnecting systems.
