Operations Manual
7. Visual and Audible Alarms
There are three types of alarm indicators: two visual (Hazard Status Bar and
Traffic Lights) and one audible (100dB alarm).
7.1
HAZARD STATUS BAR
In normal operation, with no hazard detected, a display similar to the one below
(see Fig. 7.1) is shown:

The FishSAFE unit constantly monitors the “Keyhole” and as soon as one or more
hazards is detected inside the “Keyhole” a coloured Hazard Status Bar is displayed
along the top of the screen as shown below (see Fig. 7.1a):

Whenever the Hazard Status Bar is displayed, there will always be one or more Traffic
Lights also displayed. The exact operation of these “Traffic Lights” is detailed in Par. 7.3.
7.2
HAZARD STATUS BAR CYCLING
The Hazard Status Bar can only show one hazard at a time and if more than one
hazard is detected, then it cycles around each hazard in turn displaying the
information on the hazard for 3 seconds before cycling to the next.
As well as the Hazard Status Bar changing, a special “square target” cursor
highlights the hazard on the screen.
