2 Marine Watch LT Series
2.1 Introduction
The Marine Watch LT Series is a compact yet powerful alarm system. The front panel is a
touch screen, and the main page typically displays a grid of maximum 20 rectangles. Each
rectangle represents the status of an alarm (or warning) channel.
In the event of a warning or an alarm, the corresponding rectangle indicates clearly with a
flashing behaviour, and the buzzer sounds. The event is also indicated in the standard Alarm
List, where it can be acknowledged.
The panel can be configured to display up to 9 pages. Each page layout is based on a
template, and each page can display any of the available templates.
All base I/O interfaces are built into the panel. See the datasheet for a complete overview.
The panel can also read data from a J1939 CAN bus.
Optional I/O expansion for hardwired signals can be added, typically in the form of
Auto-Maskin RIO units.
Multiple LT-ACE Annunciator Panels can be added in a standard Ethernet network.
2.2 Typical Installation
The typical Marine Watch LT installation consists of one LT-ONE Alarm Panel, and one or
several LT ACE Annunciator Panels. Signals are connected to the Alarm Panel either
hardwired, on the J1939 CAN bus or from one of the many supported RIO expansion I/O
units.
Additional LT-ACE Annunciator Panels can easily be added in a standard Ethernet network
at any time. Once connected, these Annunciator Panels configure themselves from the
LT-ONE Alarm Panel.
2.2.1 LT-ONE Alarm Panel
The Marine Watch LT-ONE Alarm Panel is
connected to all I/O.
2.2.2 LT-ACE Annunciator Panel
Any number of Marine Watch LT-ACE
Annunciator Panels can be connected in a
network.
The Annunciator Panels require no
manual configuration and are always in
sync with the configuration of the LT-ONE
Alarm Panel.

5 LT-ONE Alarm Panel Configuration
The configuration is solely required for the Marine Watch LT-ONE Alarm Panel.
Configuration changes are automatically applied to all networked LT-ACE Annunciator
Panels.
5.1 Introduction
This section covers the basic configuration of the binary/switch and analogue I/O-channels
of the Marine Watch LT-ONE Alarm Panel.
Note! The panel has sophisticated configuration options that far exceeds the use of the
panel as a basic alarm panel. This extended configuration is not typically used nor
necessary, and consequently is not covered in this manual.
For a complete configuration overview, see the 200E Series Configuration Manual on the
Auto-Maskin website.
5.2 Load and Save Configuration
The Marine Watch LT-ONE Alarm Panel can hold up to 50 configuration files.
The current configuration can be exported to either a USB memory stick or exported using
the web interface.
Likewise, any configuration can be uploaded to the Marine Watch LT-ONE Alarm Panel
using USB memory stick or the web interface.
Note! In order to apply a new configuration, the configuration need to be explicitly loaded.
5.3 Configuration Steps
There are two main steps in the configuration.
■ Channel configuration
■ Assigning the configured channel to a slot in a template
5.3.1 Channel Configuration
All channels – switches or analogue – shall be given a text description, a time delay, etc.
The Marine Watch LT supports flexible I/O, all I/O must be configured to the correct use; the
default use case is as Switch Input for all flexible I/O.
5.3.2 Assigning the Channel in a Template
The configured channel shall be assigned to a slot (a “location”) in a given template. See the
Template selection chapter.
Page 15 (24)

5.4 Login to the Panel
Before any configuration can be done one must log in to the webserver of the panel.
5.4.1 Connection and Login
Connect an Ethernet cable between a PC and the panel. In the URL-field of a web browser,
type the IP-address of the panel. The default IP address is 192.168.0.151.
Type the username and password as follows
■ Username: lt
