Condition Symptom(s) Probable Causes Recommended Action
Fail Condition • Controller indicates a
fail condition.
• The detector wiring is
disconnected or
misconnected.
• The plug-in sensor is
not properly plugged
into the three-socket
pattern in the detector
housing body.
• The detector zero
signal is low enough to

• The detector is
malfunctioning.
1. Verify that the detector wiring is
correct and secure.
2. Confirm that the plug-in sensor is
installed properly.
3. Calibrate the detector.
4. If the fail condition continues, replace
the detector.
5. If the fail condition continues, contact
