What to do if Alarm Relay is on 0–20mA at 20mA in Spectrex SharpEye 40/40?
If your Spectrex Security Sensor's alarm relay is on at 0–20mA at 20mA, it indicates an alarm condition. First, check the cause of the alarm. If there is no actual alarm, try re-powering the detector. If the problem persists, send the detector back for repairs.
Why is the red LED constantly on in my Spectrex SharpEye 40/40?
If the red LED on your Spectrex Security Sensor is constantly on, and there is no fire, it means the detector alarm is latched. Perform a reset to clear the latched alarm.
What to do if Yellow/amber LED flashes at 4Hz Fault Relay at N.O. 0–20mA at 2mA on Spectrex Security Sensors?
If the yellow/amber LED flashes at 4Hz and the fault relay is at N.O. 0–20mA at 2mA on your Spectrex Security Sensor, it indicates a BIT fault or a faulty detector. Try cleaning the detector window, then re-power the detector. If the issue continues, consider replacing the detector.
