Main Controlled Equipment: TYFON®, Morse Light, Bell, Gong and emergency signalling equipment
The TLG2000 is not simply a ship horn push button.
It is a configurable marine sound and light signal controller capable of automatically generating internationally recognized navigation signals and controlling associated sound/light equipment.
The official instruction manual describes TLG2000 as a multipurpose sound and MORSE LIGHT signal controller that can be configured according to individual vessel needs.
Depending on the vessel installation, it can work with:
One or Two TYFON Whistles
Morse Signal Light
Electronic Bell
Gong
General Emergency Alarm
Abandon Ship Alarm
External Horn / Whistle Pushbuttons
This makes the controller an important component of a vessel's bridge navigation signalling system.
One of the most important functions of the TLG2000 is its ability to automatically generate sound-signal patterns associated with the International Regulations for Preventing Collisions at Sea (COLREGs).
Kockum documentation states that the controller provides eight different signal characters with selectable/variable intervals, and signals can be emitted as sound only or as combined sound and Morse-light signals.
This is particularly useful during:
Restricted Visibility
Fog
Heavy Rain
Poor Visibility
Special Navigation Conditions
The controller therefore may also be searched by marine engineers and buyers as:
Automatic Fog Signal Controller
COLREG Sound Signal Controller
Ship Whistle Timer
Navigation Horn Controller
Restricted Visibility Signal Controller
Kockum Sonics is widely associated with its TYFON® and SUPERTYFON® marine whistles, and TLG2000 provides the control interface for compatible whistle installations.
The official manual supports configurations involving:
Fore TYFON
Aft TYFON
Fore & Aft TYFON together
It also provides manual activation and automatic TYFON signal generation.
The front panel includes whistle-selection indications showing which whistle arrangement is active.
A dedicated horn-symbol button allows the operator to activate the selected TYFON manually.
This is required when the bridge team needs an immediate whistle signal rather than an automatically timed COLREG sequence.
The controller also supports automatic signal generation.
The official TLG2000 documentation explains that predefined sound characters can be emitted automatically at specified intervals.
This greatly reduces the need for repeated manual horn operation during prolonged restricted-visibility conditions.
The actual SM MARINE SERVICE™ panel visibly shows selectable timing indicators:
40 sec
60 sec
90 sec
120 sec
These timing selections relate to automatic sound-signal operation according to the configured function.
For sourcing this exact controller, visit www.smmarineservice.com and search for Kockum Sonics TLG2000 or contact SM MARINE SERVICE™ with a photograph of the existing unit.
TLG2000 also provides MORSE LIGHT signalling.
The system can generate navigation signals using:
Sound only
or:
Combined Sound + Morse Light
depending on the selected configuration.
The controller includes a dedicated Morse-light section as well as external switching capability.
This is particularly valuable where visual signalling is required together with audible signalling.
The TLG2000 can also operate Bell and Gong equipment.
Kockum documentation specifically includes automatic Bell & Gong signalling for:
Anchor
and:
Aground
conditions.
This is especially relevant to vessel sound-signal requirements where Bell/Gong signalling forms part of the prescribed navigation signal arrangement.
TLG2000 can automatically control the connected Bell/Gong system for anchor signalling where configured.
This eliminates the need for continuously repeated manual operation during appropriate conditions.
An additional automatic sound-character sequence can be used for a vessel aground when connected to the appropriate Bell/Gong equipment.
The exact sound equipment and configuration depend on the vessel installation.
TLG2000 can also interface with the ship's General Emergency Alarm (GEA).
The instruction manual explicitly documents General Emergency Alarm signalling as a combined sound and Morse-light function, and the controller provides a dedicated GEA relay output.
An external General Emergency Alarm start button can be wired to the control unit.
This provides integration between bridge signalling equipment and the wider emergency-alerting arrangement.
The TLG2000 manual also includes a dedicated Abandon Ship activation input.
In appropriate configurations, an Abandon Ship signal can be generated as a combined sound and Morse-light signal.
Because this is an emergency safety function, any replacement controller should be correctly wired and tested according to the vessel's approved arrangement.
TLG2000 can control multiple whistle arrangements.
The manual's I/O documentation contains outputs for:
Fore TYFON
Aft TYFON
and makes a distinction between certain fore-whistle installation distances.
This allows the TLG2000 to support different ship sizes and whistle arrangements.
According to the official instruction documentation, important connection groups include:
Ship Ground
24 VDC supply to TLG2000
TYFON outputs
Bell output
Gong output
Morse Light output
General Emergency Alarm input/output
Abandon Ship input
External TYFON controls
PA Interrupt input
The controller's main electronics are powered by 24 VDC.
Depending on the external sound/light devices, associated equipment can use 24 VDC or 115–230 VAC, as documented in example wiring configurations.
One of the most important procurement references for the unit is:
Kockum technical documentation identifies this as the TLG2000 Signal Controller reference number.
A buyer may therefore send an enquiry using any of the following:
Kockum Sonics TLG2000
TLG 2000
245.80.309
24580309
BSH 6291/003/02
These identifiers should all be captured in SEO and purchasing databases.
The front panel shown by SM MARINE SERVICE™ is marked:
Independent marine supplier documentation also associates this BSH conformity number with TLG2000.
This marking is useful when identifying older shipboard installations where the purchaser may have only the BSH reference rather than the full Kockum part number.
Kockum's current DNV certificate documentation lists Signal Controller TLG 2000, Ref. No. 245.80.309 among the applicable approved product documentation.
This reinforces that the TLG2000 was designed as dedicated marine signalling equipment rather than a generic industrial controller.
Kockum documentation references several external switch types for use with TLG2000, including:
TL-70
TL-80
TL-85
and specialized emergency-alarm variants.
These are important related search keywords when customers are looking for a complete whistle-control arrangement rather than only the central controller.
The TLG2000 also provides a TYFON-active relay output that can be used with an external sound-signal surveillance arrangement such as the documented S90 Sound Signal Surveillance System.
This type of monitoring helps verify that signalling equipment is being commanded/activated as expected.
The unit includes DIMMER + and DIMMER – controls.
These adjust front-panel indication brightness for bridge operation, particularly useful during nighttime navigation.
The official documentation lists dimmer control as one of the TLG2000's standard features.
The Kockum Sonics TLG2000 can be found in bridge/navigation signalling installations on many vessel categories, including:
Cargo Ships
Container Ships
Bulk Carriers
Oil Tankers
Chemical Tankers
LNG / LPG Carriers
Passenger Ships
Ro-Ro Vessels
Offshore Vessels
The controller should always be matched to the actual vessel's signalling-system configuration.
Many vessels continue operating with proven Kockum Sonics whistle and signalling systems.
Even when newer equipment exists, replacement of only a failed control unit may be preferable to modification of the entire vessel signalling architecture, provided the replacement meets the vessel's technical and class requirements.
This creates continued demand for:
TLG2000 replacement units
Kockum TYFON spare parts
Bridge whistle controllers
Morse Light controls
Bell & Gong equipment
Legacy marine navigation signalling spare parts
SM MARINE SERVICE™ supports sourcing of these legacy and current marine signalling components through www.smmarineservice.com for worldwide vessel operators and marine service companies.

Because GEA is safety-critical, troubleshooting should follow the vessel's approved procedures.
Verify the dimmer setting and controller supply before assuming LED failure.
Inspect terminal blocks, shield grounding, power supply stability and control wiring.
Kockum's instruction manual specifically requires proper shielding and ship grounding to meet EMC requirements.
The TLG2000 is designed for panel mounting in a console, with optional provisions for wall mounting using the appropriate rear enclosure.
The installation manual also stresses that:
The enclosure must be electrically connected to ship ground, and specified terminal grounding must be provided.
Cable shielding and correct EMC installation are important for reliable operation.
An important statement in the TLG2000 instruction documentation is that the documented later version is mechanically and functionally compatible with older versions of TLG2000, while AC-powered older arrangements may require an AC/DC converter for the 24 VDC controller electronics.
Even so, replacement should still be verified against:
Reference Number
Software Version
Power Supply
Whistle Arrangement
Bell/Gong Configuration
Morse Light Configuration
GEA / Abandon Ship Functions
Wiring Diagram
before installation.
