DG-1 ME is a microprocessor-based detector of natural gas
(methane). It is recommended that you install it in areas where leakage of
methane is likely to occur, i.e. at heating equipment, cookers or ovens
supplied with this gas (in boiler rooms, kitchens, bathrooms, etc.), as well as
at gas connections and gas meters. Due to the nature of methane, which is
lighter than air, the detector should be mounted high, just under the ceiling
of the supervised room. The digital algorithm of gas detection and the function
of temperature compensation ensure correct operation over a wide range of
ambient temperatures as well as immunity to false alarms. The device detects
dangerous methane concentrations in the room, i.e. above the 20% threshold
level of the so-called lower explosive limit (10% for pre-alarm), and triggers
alarm. With the built-in buzzer and yellow LED, the DG-1 ME detector can
operate as a standalone detection/alarm device, but it is also suitable
for work as part of the alarm system. The self-diagnostic function is
constantly monitoring the gas sensor for supply voltage status as well as
correct performance, which ensures reliable operation of the detector.
