Bridge Navigational Watch Alarm System


Bridge Navigational Watch Alarm System

The purpose of a Bridge Navigational Watch Alarm System (BNWAS) is to monitor bridge activity and to detect operator disability which could lead to marine accidents.

BNWAS - P7007
Bridge Navigational Watch Alarm System

The awareness of the Officer of the Watch (OOW) is monitored through an alarm reset or motion detector and the BNWAS automatically alerts the Master or other qualified OOW if the original OOW becomes incapacitated and is unable to perform their duties.

John Lilley and Gillie’s Walker P7007 Bridge Navigational Watch Alarm System (BNWAS) combines the very latest in BNWAS technology with ease and functionality of the new integrated touch-sensitive display unit.

The full system can be supplemented with the Walker P7008 Remote Rest repeater unit. This compact and attractive remote reset unit accompanies the main BNWAS P7007 unit to allow greater versatility and additional safeguards for the whole system.

The P7008 unit copies the main reset function of the main BNWAS unit and incorporates touch-sensitive buttons, a compact digital display and individual dimmer buttons on each individual unit.

A further standard feature is the built-in motion sensor giving the flexibility of acting as a remote sensor unit as well as a reset.

This compact, easy to use unit complies with the IMO’s Maritime Safety Committee regulations which are mandatory on all marine vessels over 150 gross tonnages. It also comes with the assurance of exceptional design, build quality and reliability from a company that has over 200 years of experience in marine equipment engineering.
