Totem BNWAS was developed by Totem Plus with simplicity in mind. The system can be installed and commissioned by the crew in a few hours, using the serial communication bus between all alarm units (one cable fits all). Setup of timers and backup officer selection is easily done directly from the LCD of the main unit display. Two officers can be designated as backup officers at any time. It helps to keep the captain always informed re the situation on the bridge or train junior officers on their duty. Alarms can be selected from several different audio signals to distinguish it from other alarms on the bridge and in cabins.

The system reset can be done in three different ways: by pressing reset buttons on the bridge, by reset orders from other navigation systems capable of that function (example: ECDIS systems that can reset the BNWAS on any user command, such as the Totem ECDIS), or by movement detection by motion sensors. Movement detection in Totem Bnwas is using the latest dual technology to avoid false resets: Microwave and Infrared. Such external resets (including motion detections resets) increase crew welfare in the sense that normal operation on the bridge will not demand tedious manual resets by the OOW, and will not add extra pressure on a possibly overloaded navigator. An added value, unique for Totem BNWAS: the BNWAS can be turned into a burglar alarm in port, and will alarm on any un-authorized motion on the bridge such as thieves and burglars.
