600-GD Gas Detector

BEPMARINE gas detectors are processor-controlled and provide reliable sensor sensitivity for both LPG, CNG and gasoline vapors. Standard delivery includes a gas sensor with a 5 m connection cable.
BEPMARINE gas detectors should always be connected to the operating voltage, and therefore they have no on/off switch. This ensures maximum safety while you are on your boat or in your vehicle.
Explosive gas mixtures have a different density. Some are heavier than air and accumulate on the ground, others are lighter and rise, thus collect below the vehicle's roof.
You should always keep this in mind, when installing gas sensors!
By using the GD types with a second gas sensor, all potential hazards are taken into account and maximum safety is achieved.
For LPG and gasoline vapors that are heavier than air, mount the sensor near the ground, where the vapors are likely to accumulate.
For CNG vapors that are lighter than air, mount the sensor in the area of the ceiling, but not above cooking or heating equipment!

BEPMARINE 600-GD
A second gas sensor can be connected to the 600-GD. This way you can monitor the gas box, bottle stowage and the bilge or the area below the cooker/stove.
Each monitoring circuit is equipped with a separate 3-color control LED which indicates the respective system status: during normal function: green, in the case of system errors: yellow and in the event of an alarm: red.
An internal, acoustic alarm (piezo buzzer) as well as additional connections for further external alarm transmitters (e.g. item 23403) or a fan complete the device's safety features.
The system may be tested by means of the "TEST" button.
Dimensions (WxHxD): 88 x 67 x 17 mm / 2.4" x 3.5" x 0.7". Operating voltage: 10-32 volts.

Optical (LED) and acoustic (piezo) signals for sensor 1 and 2*
LED GREEN - no explosive gas mixture, no signal tone
LED YELLOW - sensor error detected, slow beep
LED RED - alarm, gas present, quick alarm sound

Signal tone medium/slow - warm-up phase - all LEDs flash yellow
Signal tone quick - ALARM - LED lights up red
Signal tonre slow - sensor error - LED lights up yellow

BEPMARINE gas sensor BL-SL-L

• Housing dimensions Ø x H: 42 x 21 mm
• Connection cable Ø x L: 3.5 mm x 5 m, wire colors red / green / black
• Distance between mounting screws: 37 mm
• 2 Phillips self-tapping screws 1.9 x 13 mm included

The sensor must be mounted in an area that is protected against (bilge or splash) water.
If the gas sensor gets wet, it is no longer safe/ready for operation and must be replaced!

The original gas sensor as a second sensor or spare can be ordered here.
