General Information
According to the International Regulations for Preventing
Collisions at Sea 1972, Rule 33, vessels of 12m in length or
more shall be equipped with a bell, and vessels of 100m or
more shall, in addition, be provided with a gong with the tone
and sound which cannot be confused with that of the bell.
The device shall produce a sound pressure level of not less
than 110 dB at 1 metre. The electronic Bell & Gong system
is especially developed to meet these regulations.
The Bell and Gong sound emitters are identical and electro-
dynamic. They are, also, small and compact compared with
many other loudspeaker designs. The design is advantageous
from different aspects — not only the aesthetic.
By means of modern electronics, a power amplifier BG
300 supplies the sound emitters with the signal characters
stipulated by regulation for "ship aground" and "ship at
anchor". To emit the prescribed signal characters, the
Bell and Gong units are activated by buttons on the Signal
Activator TI65-M.
Operating
The Signal Activator TI65-M has 2 manual push buttons, each
for bell and gong, and one 3 way switch knob for automatic
activation of the repeating character shown to the right.
The switch knob has also an off function in the middle position.
Just turn the knob to desired character and the Electronic
Bell & Gong will start automatically.
By using the manual push buttons each Bell or Gong can
be operated.
