LPG Gas Detector with Exterior Sensor & Solenoid Valve Control. BEP 600-GDL.

LPG detector features:

Visual and audible alarms.
A test mode checks operation of sensors with indicators for fault detection.
Self testing capability
Microprocessor control
Provision for external alarm
Provision for bilge blower
Dual sensor capability
One sensor supplied - with a 5m cable
Automatic shut-off solenoid control with pulse and hold circuit for low power draw

Technical specs:

Power supply: 12V nominal
Alarm sensitivity: 20% LEL (lower explosive limit)
Current draw with 2 sensors: 350mA (max)

Additional items available for gas detector:

* Gas Solenoid Valve
Nominal solenoid voltage: 12V
Gas outlet: 3/8" BSP
Gas inlet: POL Thread
Current draw: pulse 700mA, hold at 250mA
Regulator flow Rate: 3kPA

Notes:
The 600-GDL is designed for 12V DC systems only. For 24V installations, a voltage reducer must be used. If you are using a different solenoid valve, the current draw must be checked to make sure it is 800mA or less at 12.5 volts.
For LPG and Petrol fumes which are heavier than air, mount the sensor in a low dry position where the gas is likely to sit. Sensor must be mounted clear of bilge water.
For CNG gas, which is lighter than air, mount the sensor just below ceiling height but not above cooking or heating areas.
