The Poole based Nereus Alarms Systems combine over 10 years' gas detection experience with modern digital electronics to provide advanced and reliable protection. Their comprehensive range of gas alarms are available which feature cabin-mounted LPG and carbon monoxide sensors as well as the recently developed waterproof Bilge Sensor for LPG. Unlike most sensors on the market which are destroyed by water, the bilge sensor from Nereus Alarms will survive total immersion.

The Nereus WG1000 can be supplied with relay outputs to drive ancillary equipment or connect to security systems. It is also available with remotely controlled gas valves which will automatically shut-off the gas in the event of an alarm.

Each Nereus WG1000 alarm system is made up of a separate electronic control unit, display panel and sensor(s). This gives a very flexible and easy to install system. The control unit can be sited anywhere convenient and can be mounted in a position where cable runs are simple. The separate display panel is small, slim and styled to fit neatly in the cabin or instrument area. Sensors are supplied as either flush-fitting cabin sensors or waterproof bilge sensors.

Lamps and an audible buzzer clearly indicate all warning and alarm states. Separate alarm signals are given for LPG alarms, low voltage warning and fault warning. A single button is used to test the unit and to hush the buzzer when in alarm. All systems are factory calibrated and require no maintenance or adjustment.

The latest technology sensors combine high performance with very low power consumption. Every second the electronic control unit automatically checks for broken or damaged sensor connections and system faults. A separate fault lamp indicates any problems to the user. All electronics are encapsulated in solid epoxy to provide mechanically robust systems that are not affected by vibration or moisture.

“They say looks can be deceptive, the Nereus WG1000 alarm is not the best looking, however, just the fact that the sensors are water proof makes this a good alarm, but its performance, sounding at 12% LEL coupled with its power consumption make this in my opinion the best alarm we sell. A twin sensor alarm unit is also available.”
