Bridge Navigational Watch Alarm Systems Spare Parts Suppliers
A Bridge Navigational Watch Alarm System (BNWAS) keeps the bridge alarm chain working when the officer of the watch stops responding.
Like all electronics at sea, the unit eventually needs replacement parts. Reset buttons wear out from constant pressing. Motion sensors collect dust and lose sensitivity. Controllers fail under voltage spikes. Sounders age and crack. Each of these stops the system from passing its annual class survey.
BNWAS spare parts suppliers keep the right components in stock and matched to the right brand. RecordsMarine's directory groups vetted vendors by region, so a chief officer can find replacement stock before the next survey window.
Common BNWAS Spare Parts
The parts ordered most often:
- Reset buttons for bridge consoles
- Motion sensors (PIR and microwave types)
- Main controller units and timer boards
- Power supply modules and backup batteries
- Cabin and crew alarm sounders
- Visual flashing beacons and indicator lamps
- Wiring harnesses and connector blocks
- Front panel keypads and displays
- Software memory cards and firmware modules.
Reset buttons and motion sensors are the highest-turnover items. Suppliers of BNWAS spare parts typically stock these in depth across the major brands. Controllers and timer boards have lower demand but longer lead times when ordered.
Brand-Specific Stock Matters
The BNWAS market splits across Daniamant, Furuno, JRC, Tokyo Keiki, McMurdo, and Marine Technologies.
Parts cannot be swapped between brands. A Daniamant motion sensor will not fit a Furuno controller. Software keys, connector pinouts, and reset codes all differ.
BNWAS spare parts distributors with strong inventory carry stock across at least three brands. Single-brand specialists go deeper on one platform but force the buyer to manage multiple supplier relationships across a mixed fleet.
OEM and Aftermarket Stock
Most ships use both channels. OEM parts come directly from the system maker and carry full type approval. Aftermarket parts are sourced through authorised resellers and often ship faster. Both work for non-critical items like wiring harnesses and indicator lamps. Safety-critical items, such as controllers, motion sensors, and reset buttons, should always carry valid type approval paperwork.
What to Check Before Ordering
A counterfeit controller can pass bench testing and fail two months into service. Class surveyors check part documentation during the annual safety survey, and a missing certificate can hold the ship in port. Before approving any new BNWAS spare parts suppliers, confirm:
- Direct OEM sourcing or documented aftermarket chain
- IMO MSC.128(75) type approval certificates with each part
- Stock lists matching the brands fitted to your fleet
- Delivery to your main trading ports
- 12-month warranty minimum on electronic boards
- Returns policy on incorrect or sealed items.
Stock Onboard
Most ships keep a small reserve in the bridge spares locker. One spare reset button per console, one motion sensor, and a set of fuses cover most common failures. Larger items like controllers are usually ordered when needed rather than held in stock.
Frequently Asked Questions
Can a BNWAS run with a failed motion sensor?
Yes, in manual mode. The system reverts to button-only reset until the sensor is replaced. Class surveyors accept this as a temporary condition but expect repair within a defined window.
How long do BNWAS reset buttons typically last?
Most last five to eight years under normal bridge use. Heavy-traffic ships replace them sooner. Premature failure usually means a wiring fault or a faulty batch.
Are software memory cards swappable between identical units?
Sometimes. Some models tie firmware to the controller serial number and require an OEM-issued unlock. Confirm with the supplier before ordering a card-only replacement.
