The Need for a Petrol Vapour Alarm
Petrol or gasoline is often used to fuel outboard motors. When the tanks are sited on board the risks from any leaking fuel can be great. A naked flame or a spark from an engine or switch is all that is required to ignite the vapour and cause an explosion.
The Usual Problem - Water Damaged Sensors
The problem is where to site the sensor. A sensor mounted anywhere in the bilge is prone to water damage. This is especially the case when mounted low in the bilge, ie where it needs to be fitted. Once wet, traditional sensors are permanently damaged and can give a continuous false alarm. This leaves the crew unsure how to act not knowing whether the alarm is due to a fuel leak or damaged sensor. Apart from the inconvenience, this results in an expensive repair and a period without protection.
The Solution - Unique Waterproof Sensor
To overcome this problem, Nereus Alarms has developed a unique waterproof sensor which is used in their PV range of vapour alarms. These remarkable sensors will survive both splashing water and total immersion and are the only ones of their type on the market.
Whether you use your boat for business or pleasure, you will benefit from reliable protection without the hassle or dangers of water damaged sensors.
Other Features
The alarms are small, neat and stylish. They are easy to install, simple to use, are supplied with full instructions and require no maintenance. Lights on the control unit indicate power, fault and alarm conditions. All models have an internal alarm buzzer and an output to drive additional remote sirens. A separate relay output is also provided which can be used to connect to a control system.
Fast Response & Low Power
The latest technology sensors combine fast response and high performance with very low power consumption.
