The control panel is an optional element of any Cygnus system, used to capture data from up to 480 devices situated around a site. This data includes active alarms and faults and all events are recorded into a file which can be viewed or downloaded. The control panel is mains powered but has its own internal rechargeable battery power source, which fully charged, will last 4 weeks. The panel has other features including an evacuate site function which can be used in case of emergency and is also used to switch intruder sensors on or off.
