The exchangeable sensor
The exchangeable sensor X-Change PolyGard2 and PolyXeta2 (Ex-proof)
Exchangeable sensors type a x-change PolyGard2 and PolyXeta (Ex-proof) are the product of the new generation of sensors and the control panel detectors are connected via RS 485. The advantage of this type of sensor is that when replacing the sensor can be calibrated independently the motherboard sensors so that existing sensor replace the other, new or calibrated without you change the whole detector.
