Description
Optical smoke detector, intrinsically safe version for connection to ATEX control unit | EVC-PY-IS ATEX
Description EVC-PY-IS ATEX
The EVC-PY-IS ATEX detector is used in areas that require Ex-protected or intrinsically safe smoke detectors.
The smoke detector provides a fast and reliable warning. The detection chamber contains a light source and photodiode. The light beam normally does not hit the photodiode, but as soon as smoke enters the chamber labyrinth, the light-emitting diode is reflected by the smoke, thus striking the photodiode. The current through the photodiode changes and triggers an alarm.
The alarm status is visually indicated by a red light indicator on the detector, and it remains in the alarm State until manually reset in the distribution box or control unit.
The design of the detector makes it almost completely insensitive to high air velocities, contamination, and radio frequency interference.
The detector is equipped with a bayonet mount, making it easy to install and remove.
Contamination of the smoke detector increases its sensitivity and will cause it to slowly enter alarm mode. To prevent unnecessary alarms, the detector must be cleaned at least once a year. Please consult our user and maintenance instructions.
