BNWAS 150 System Overview

The BNWAS 150 system is designed for use on a vessel’s navigation bridge. The remote alarm sounders cover key locations such as the officer cabins, mess area and ship’s office. Reset devices can be used on the bridge wings.
The display control and monitoring equipment is to be installed in protected areas inside the bridge.

Dormant Time

This function is adjustable between 3-12 minutes in 1 minute increments only whilst in SETUP mode.

Remote Resets

BNWAS 150 has a reset mechanism which can be activated by a combination of reset pushbuttons and PIR motion detection sensors.

Fail Alerts

BNWAS 150 has alert messages for Tamper, Power and Battery. Tamper alert is also audible by means of an on-board buzzer within the display control unit.

Emergency Call and Cabin Call

BNWAS 150 has an Officer call configurable in up to 5 officer cabins within the menu.

Power supply

BNWAS 150 is powered by two separate 24 Volt supplies (main and backup) which will automatically switch to the backup supply in the event of a main supply failure. This will raise an alarm.

Inputs from Valid Reset Devices & System Alarms

BNWAS 150 provides additional Digital Inputs to accept signals from other devices and transfer alarms. An external equipment in alarm will send a digital input to the BNWAS and the source will be shown on LCD display. These might include RADAR or ECDIS.

External valid reset inputs must be approved by the appropriate approval body before being used. AMI Marine (UK) Ltd will assist with recommendations wherever possible from previous experience but will not accept responsibility if not accepted.
