Further, the offered Programmable Logic Alarm Unit indicates when find some abnormal situation.
An input signal origination from a potential free contact, normally open (NO) or normally closed (NC), will cause the appropriate alarm LEDs to flash and simultaneously the related output will activate. Te internal siren relay will be activated on the detection of every new alarm. The visual warning consist of a flashing two red LED for each channel and a relay that activates the horn.
