Boat Fire Detection System Installation
A fire aboard is most dangerous when nobody knows about it, so a boat fire detection system gives warning early, whether you are asleep below or at the helm with the engine room out of sight. We look after the electrical side: positioning and wiring detectors and alarms, and giving them a reliable supply.
Electrical faults are a common cause of fires on boats, which is why good detection goes hand in hand with sound wiring, correct fusing and well-made connections.
We are based at Shoreham Airport and work aboard at the berth from Brighton to Southampton.
What a detection system can include
Smoke alarms in the cabin and sleeping areas warn of a fire in the accommodation. The engine room is better served by heat detection, because exhaust and fumes can trigger false alarms from smoke detectors there. Detectors can be wired to an alarm panel or sounder at the helm so the warning is heard where you are. Carbon monoxide alarms suit boats with heaters, generators or engines that could leak fumes into the cabin.

Power and wiring
A wired detection system needs a supply that stays on when the rest of the boat is switched off, fused properly and protected from the battery isolator being turned off by mistake. Cable is routed away from heat and chafe and secured so it survives vibration. Battery-powered alarms are a good simple option for many smaller boats, and we can advise on positions.

Extinguishing systems
Some boats have an automatic engine room extinguisher. Its electrical link to engine shutdown and helm indication is something we can wire. The extinguisher itself, its sizing and servicing should come from its supplier or a specialist.
Reducing the risk in the first place
Detection tells you there is a problem; good wiring helps stop one starting. Overheating connections, undersized cable, missing fuses at the battery and poorly installed lithium banks are all things an electrical inspection can pick up. New detection can be paired with a survey of the existing electrics.

Before work starts
Tell us the boat, its layout and whether it has heating, a generator or lithium batteries. We look at detector positions and power, then give you a written quote.
Lithium batteries and detection
A properly installed LiFePO4 bank with its battery management system and correct fusing is a safe installation, but owners fitting lithium often want detection near the battery compartment too. A heat detector there, linked to the helm alarm, gives early warning of an overheating connection or charger fault. We fit lithium banks with the fusing and protection they need, and can add detection at the same visit.
Testing alarms regularly is part of owning them, and we show you how to do that at handover.
Frequently asked questions
What fire detection does a boat need?
Smoke alarms in the accommodation and heat detection in the engine room are a sensible starting point, with carbon monoxide alarms where there are heaters or engines nearby.
Why use heat detectors in the engine room?
Fumes and exhaust can set off smoke detectors falsely there. Heat detectors respond to a real temperature rise.
Will the alarm work if I switch the batteries off?
A wired system should have a supply that stays on when the main isolator is off. We plan that as part of the installation.
How much does fire detection wiring cost?
It depends on the number of detectors and cable runs. We assess the boat and quote in writing.
