Smoke detector

KRM-X-2

KRM-X-2 duct smoke detector is designed for smoke detection in ventilation ducts.

The detector is a combination of a smoke detector and an adapter system.
The adapter system has been specially designed for optimal air flow through the smoke detector.
The air duct sensor measuring tube transports the air through the sensing chamber and back into the air duct.
Measuring tube is designed to detect smoke at very low flow rates.

APPLICATION

KRM-X-2 sensor smoke detection is based on light scattering.
The device housing includes a RM3.3-X / ALN-E type smoke alarm as well as flow monitoring, electronics, terminals and user interface.
KRM-X-2 reacts immediately to smoke and triggers an alarm. Over time, the sensor becomes contaminated.
Because of alarm threshold tracking, the sensitivity up to total pollution remains the same. The contamination level is indicated in a two-digit LED display.
KRM-X-2-MOD and KRM-X-2-BAC models are equipped with bus interface RS-485.

INSTALLATION

KRM-X-2 can be mounted directly to a rectangular and uninsulated ventilation duct.
To mount the detector to round or insulated duct, a special fitting plate is needed.
The product is equipped with 160 mm measuring tube which is normally enough for most applications. Longer tubes are also available.
