1. Introduction
1.1 Description
SMART3-R gas detectors allow monitoring flammable, toxic and refrigerant gasses in ma-
chinery rooms, laboratories and non-classified areas.
The gas detector is compliant to the following standards:
EN 50676, EN 378-3, EN 14624, IEC 60335-2-40 Annex LL, ISO 5149-3.
The gas detector has an analogue 4-20 mA output, a serial RS485 output and 3 relays. It has
a 12-24 Vdc power supply as standard, but as optional there’s a 230 Vac version. SMART3-R
gas detector can be equipped directly with a sensing element or with a remote head, thanks
to a 6-conductors cable.
The plastic enclosure has two M20 cable glands and on the sides there are pre-formed gui-
des that can be drilled to add up to six M16 cable glands. The circular plastic contour offers a
visual indication of the detector’ status while an internal buzzer activates to warn of any fault
or alarm condition. The gas detector has a continuous self-diagnosis. With the calibration
keypad STS/CKD+ it’s possible to calibrate and adjust the gas detector.
