Input module introduction:

Features. When the monitored device operates, it receives and feeds back the action signal to the fire alarm controller, and can access the normally open or normally closed signal of the monitored device.

Principle. The action signal of the monitored device is loaded into the address code and transmitted back to the fire alarm controller (coupling type) through the signal bus to send an alarm signal, and can also be used as a linkage trigger signal.
