Description

BS-380, BS-381, BS-382, BS-383. Gas detectors which are suitable for laboratories, industries, car parking stations
e.t.c. They have a 4-20mΑ analog output and are suitable for panels and peripherals (pg. 55). These gas detectors are
mounted in a vertical position with the detection nozzle pointing downwards. If the detected gas is considered
“light” (its molecular weight is smaller that 29) then the detectors are place above the probable leakage points. If the
detected gas is considered “heavy” (its molecular weight is above 29) then the detectors are placed below the
probable leakage points.

> BS-390, BS-391, BS-393. The anti-explosive type gas detectors are detectors that are suitable for hazardous
environments. They are certified for environments: II 2G Eex d IIC T6. They have a 4-20mΑ analog output and are
suitable for panels and peripherals.

> These gas detectors are mounted in a vertical position with the detection nozzle pointing downwards. If the
detected gas is considered “light” (its molecular weight is smaller that 29) then the detectors are placed above the
probable leakage points. If the detected gas is considered “heavy” (its molecular weight is above 29) then the
detectors are placed below the probable leakage points The connection with the panel is done using 3 cables. A
shielded cable with a rating of 3 x 1.5mm2 is required for a distance up-to 300 meters and 3 x 2.5mm2 for
distances up-to 300 – 600 meters.

> BS-316. Expandable gas detection panel with a microprocessor, 16 inputs for connection with gas detectors 4-20
mA, programmable outputs (opened relay contacts). Cooperates with detectors 4-20 mA that are connected with 2
or 3 cables to the panel.
