Alarm Monitoring System
A reliable proven indigenous solution
ALMOS 4
♦ 50+ installations on various types of vessels like
tankers, container, bulk, passenger, OSV, AHTS and tugs
♦ Supports distributed and centralised architecture
♦ Uses robust and powerful marine approved
WAGO IO system and controllers from Germany
♦ In-house design and development centre.
Software is developed on the Codesys
platform in compliance with international
industrial standard IEC 61131-3
♦ Supports various network topologies and most
industrial communication protocols - Modbus
TCP, Modbus RTU, CANOpen, Profibus, Profinet, Asi etc.
♦ 25+ years of dedicated services in marine and
control automation




It is an in-house developed product of ACSPL. It is built on
powerful marine approved hardware from WAGO Germany
using the IEC 61131-3 complaint e!Cockpit platform and
designed to meet each customer’s requirements. It can be
expanded to feature repeaters in other control stations such in cargo control room and wheelhouse, extended alarm system for accommodation rooms to meet UMS class specifications with deadman monitoring.

Dynamic mimic diagrams assists the engineers and operators to easily understand the process status and critical parameters. Readings and indications on the mimic are colour coded depending on if they are normal, alarm condition, blocked or inhibited. These diagrams can be designed to illustrate Main engines, Auxiliary engines, Power networks, Shaft and propellors, Boiler and any other process network as per customer requirement.
ALMOS 4 Alarm monitoring system works with centralised or distributed signal acquisition units and remote terminal units to acquire, filter, analyse, store and monitor alarms and events. It is standalone, secure an independent from machineries and other engine room equipments.




Bar Graphs provided for exhaust gas temperature and mean deviations show the combustion
performance of each cylinder making any
abnormality very observable in a glance.
​
Trends for various engine temperature and
pressure parameters can be monitored
historically to view process system stability.
All alarm channels are classified into various machinery wise groups. This list provides full detailed status of all monitoring parameters. It shows the channel number, name, type of channel, current reading, alarm set points, blocking/inhibit status, event acknowledge and reset status. With support for auto-alarm blocking, when any engine, generator or other machinery is shutdown, it will automatically block alarms and events occurring from the respective alarm channels. This will reduce the number of unnecessary notifications to the operators. The entire alarm monitoring is secure with multi-level password based security system to ensure that no unauthorised changes can be made to the system.
ALMOS 4 integrates engineer duty watch system. The duty engineer, operating mode of the vessel is selected in the engine control room after acknowledgment from bridge. If an alarm is failed to be acknowledged in control room, the alarm is forwarded to the duty engineer’s cabin and then to all repeaters.
​
ALMOS 4 is designed to have internal self diagnostics monitoring which can check for any power supply failure, card failure, communication status, memory card status,
UPS status, sensor signal failures, reset button short circuit fault, control panel temperature and other parameters to ensure smooth and reliable operation of the alarm
monitoring system.
