A Complete Range of Alarms
Nereus Alarms offer a complete range of gas alarm systems for detecting LPG butanepropane. Designed specifically for use on boats, these systems use modern electronics and design techniques to provide unrivalled protection.
The Need for a Gas Alarm
A leak of LPG LP Gas can result from any number of situations such as split or perished flexible hoses, chaffing pipes, leaking joints, poorly installed appliances, cracked cylinder lockers, loose cylinder regulators or unlit burners. Being heavier than air, LPG will sink and collect in the bilge or any available compartment. A naked flame, electrical spark or hot exhaust is all that is required to cause an explosion.
The Usual Problem - Water Damaged Sensors
Traditional LPG sensors mounted in any wet area eg bilge, cylinder locker, galley are prone to water damage. Once wet, these sensors are permanently damaged and often give a continuous false alarm. Not knowing whether the alarm is due to a gas leak or damaged sensor, the crew are left unsure how to act. 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 WG range of alarm systems. 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 trouble or dangers of water damaged sensors.
The alarm systems are small, neat and stylish. They are easy to install either flush or surface mounted, simple to use and require no maintenance. Lights on the control panel indicate power, fault eg damaged wire to sensor and alarm conditions. All models have an internal alarm buzzer, an output to drive additional remote sirens and a separate alarm relay output.
