Watch alarm system (bridge navigational watch alarm system)

The bridge navigational watch alarm system monitors bridge activity and detects operator disability that could lead to marine accidents. The system monitors the awareness of the officer of the watch (OOW) and automatically alerts the master or another qualified person if for any reason the OOW becomes incapable of performing their duties.

Telegraph logger (command printer)

The sm electrics telegraph logger (command printer) has been designed to replace an outdated bell logger (telegraph printer). The command list of the telegraph logger is able to represent up to 60,000 commands before the list gets refreshed.

The telegraph logger will periodically execute an internal backup of the command list, which will be exported to an excel sheet. All files are named with the specific timestamp and kept in an internal system folder.

NAS 24 nautical alarm system

The NAS 24 nautical alarm system has been designed to indicate binary alarms on a common screen especially for marine applications.

All alarm channels are permanently indicated even though they are not active to give a full overview of the monitored states. Compact i/o module to be mounted on terminal rail TS35 and type approved by all major classes.

Bridge Alert Management (BAM) with integrated BNWAS

The Bridge Alert Management System (BAMS) has been designed to give sustained support to the Officer of the Watch, especially in multiple alarm situations by merging all possible alerts into a harmonised presentation on a central screen. This centralised alarm management tool is guiding the OOW by indicating all connected nautical systems in graduated categories.

The bridge alert management system BAM le guardian 3000 controls all audible alarms on the bridge by a bi-directional alarm, acknowledge and sound off interface. The system provides alarm specific instruction assisting the OOW to react appropriately. A continuous event log ensures data is permanently available for systematic analysis of critical incidents or other exceptionals.

An integrated type-approved (wheel marked) bridge navigational watch alarm system (BNWAS) transfers unattended alarms automatically to selected backup officer areas. A connecting module is monitoring all BNWAS alarm devices and reset facilities. Intelligent features, such as a self-test routine, are included as standard, evidence of the company’s long-standing experience.

Engine order telegraph (EOT)

sm electrics’ Engine Order Telegraph (EOT) and Em’cy Engine Order Telegraph Systems (EEOT) formerly designed and distributed by Interschalt respectively Stein Sohn represent the embodiment of safe and sustained µP controlled human-machine interface embedded as a basic part into the connected propulsion remote control system.

Type approved by major classification societies the equipment is available for various control applications. The highly integrated system is administrating a single interface to the potential propulsion system by a high-precision shock-resistant potentiometer, contact-free optical current transmitter or other defined physical interface unit. The well-established µP controlled ‘Electrical Shaft’ allows a secure Bridge FWD EOT’s remote control by corresponding lever controller located typically on the Bridge Wings and/or Bridge AFT.

A simplified µP controlled Emergency Engine Order Telegraph (EEOT) system operates as the final back-up system in a case the general propulsion remote control system and its back-up mechanism fail.
