Combined Signal Automaton 10+SGA
for the release of the sound and light signals
of whistle, signal lamp, bell and gong
1/5
The Signal Automaton 10+SGA allows the automatic release of ten different signals according
to Rule 34 (a, b, d) and Rule 35 (a, b, c, e, g) of the Colreg 1972 and for general emergency
alarm through an external key.
At the same time the signal automaton serves as automatic control for the:
1.
white maneuver signal lamp (visibility range at least 5 nautical miles)
2.
automatic bell
3. automatic gong, for vessel of 100 m or more in length
The following signals can be released:
Maneuvring signals:
Rule 34 (a) and (b)
1. …one short blast
- course alteration to starboard
2. …two short blasts
- course alteration to port
3. …three short blasts
- operating astern propulsion
Each of the above mentioned signals will at the same time once be released acoustically and
optically. After at least 10 seconds the same signal will be repeated only as a light signal.
When the maneuver is finished, the off key "O" must be hit for switching off.
4. Rule 34 (d)
When vessels in sight of one another are approaching each other and from any cause either
vessel fails to understand the intentions or actions of the other, or is in doubt whether
sufficient action is being taken by the other to avoid collision, the vessel in doubt shall
immediately indicate such doubt by giving at least five short and rapid blasts on the whistle.
Such signal may be supplemented by a light signal of at least five short and rapid flashes.
Sound signals in restricted visibility:
5. Rule 35 (a)
...one prolonged blast at intervals of not more than 2 minutes:
- a power-driven vessel making way through water
6. Rule 35 (b)
...two prolonged blasts in succession with an interval of about 2 seconds between them:
- a power-driven vessel underway but stopped and making no way through water
7. Rule 35 (c)
...three blasts in succession, namely one prolonged followed by two short blasts:
- a vessel not under command, a vessel restricted in her ability to maneuver, a vessel
constrained by her draught, a sailing vessel, a vessel engaged in towing or pushing
another vessel
(Can optionally be replaced by Morse letter “U” for offshore structures acc. to IALA.)
