Switch Signals

Switchingsignal also could be called digital signal. As we know, the direction and thequantity of the analog signal would be changing continuously by time going,while the changing of switching signal is not continuous, but abrupt change, so it’s also called pulse signal.Comparing with the analog signal, it has the characteristics of stronger anti-interferenceability, and is widely used in modern electronic technology signal processing.

Theswitching signals are with two initial states, normally open and normallyclosed, they are represented by "NO" and "NC"."NO" is short for normally open, it means that the circuit would stayon, unless the detection detected. While "NC" is short for normallyclose, it means that the circuit would be closed, unless the detectiondetected.

ATL-DG311 couldoutput switching signals, so when it’s connected with other fire securityequipment, it would output the signal to the fire equipment to out the fire. It’svery suitable for monitoring the fire hazards in factories, warehouses,communications rooms and relevant other places.
