Description

From the listing uploaded by “appupdater”.

AudioLINK data download technology from Aico/Ei Electronics has been improved; AudioLINK+ is now faster, quieter, and more reliable. This second iteration of the award-winning technology makes it easy to get real-time data from alarms using sound pulses generated by the alarm, received and decoded by the microphone and AudioLINK+ App on your smartphone – saving time, money and lives. All you need is an AudioLINK or AudioLINK+ enabled alarm, a smartphone and the AudioLINK+ App. The AudioLINK+ App is fully compatible with the previous version of AudioLINK. AudioLINK data extraction technology is built into our existing Ei3000 Series, Ei650i, and Ei208 Fire and Carbon Monoxide alarms, in addition to our discontinued Ei2110e and Ei261 alarms. Data extraction can be carried out on-site without having to remove the alarm ensuring continued detection. • A simple to read Alarm Status Report is generated straight away – giving details of any incidents immediately. • Data may be extracted for AudioLINK alarms again and again. • Information is stored for the life of the alarm enabling historic information to be retained. • The Alarm Status Report provides the evidence required for maintenance records. • The Report may be emailed to form part of a property’s record. Alarm Status Report The App generates a simple to read colour coded report giving information on a range of alarm data: • Alarm activations. • Sensor status. • Record of testing. • Battery status. • Carbon Monoxide (CO) levels recorded (CO alarms only). • Background levels of CO (CO alarms only). • Dust contamination levels 3000 and 650i Series only).
