    Gas Detection Control Panel

     

    The Gas Detection control panel manages up to 20 conventional detector lines (zones) for SL-020 models or up to 36 lines for SL-036 model. 

    Each line (zone) accepts up to 30 devices and is  provided with an additional I/O line that can be  configured as an open-collector output (the  activation principles can be defined during the  configuration phase) or as an independent input  line (separate from the zone) for fire detection,  gas detection line, etc. 

     The available control panel models are:

    • SL020-2 - with 2 zones non expandable

    • SL020-4 - with 4 zones expandable to 20

    • SL036-4 - with 4 zones expandable to 36

    METHANE DETECTOR

    The 295 series is a three-wire 4÷20mA transmitter able to detect combustible gases by employing a catalytic sensor calibrated up to 20% LEL to different gases and find their best application in centralized alarm systems.

    The instruments is flameproof certified and comprise of an enclosure in which the electronic circuit and the terminals are mounted and a downward facing cylindrical sensor housing with inside a replaceable “Cartridge Sensor”.

    The instrument has a 4χ20mA linear output (S) with 20%LIE (Lower Explosive Limit) F.S. of detected gas. 

    The Printed Circuit Board, F1 and F2 key using for Test and Calibration routine, protected by a code, and 3 LED shows the working conditions:

     

    Red LED "ALARM": 20% LEL alarm indication.

    Green LED "ON": normal working condition.

    Yellow LED "FAULT": the sensor should be faulty, disconnected, out of scale or expired.

     

    293 Methane CH4 is calibrated to detect  Methane, a gas lighter than air.  Its density as to air is 0.55 andits LEL (Lower Explosive Limit) is 4.4%volume.

     

    INSTALLATION

    it should be fixed at 20-30 cm from the ceiling  (the Methane gas is lighter than air).

     

    Average life: The sensitive element used in this detector has an excellent stability in time.  In fresh air and in normal working condition the sensor's life is about 5 years from the date of installation.  After this period the yellow LED “FAULT” flashes every 4 seconds, is necessary replacing the “Cartridge Sensor”.

     

    Note: the detector is not able to detect gas leaks  occurring outside the room where it is installed, neither inside walls or under the floor.
