Condition Description
Failure to communicate This condition occurs if your security system cannot communicate to
the central monitoring station. Your system will try to report to the
central monitoring station eight times before it tells you there is a fail-
to-communicate problem. Trouble beeps will start and the Status
button will light. Press the Status button and the display will show
“Comm Test Fail or Comm Failure”. You may need to call your security
system dealer if the problem continues.
Sensor open This condition occurs if a door or window is open or a system sensor
has been disturbed and not reset properly. For example, a
door/window sensor magnet may have been removed from the
sensor. Your system will indicate this condition to you by causing the
Status button to light. When you press the Status button, the display
shows, for example, “SN 1 Front Door Open”. Correct the problem by
resetting the sensor. If this condition continues, call your security
system dealer.
Sensor tampered This condition occurs when a sensor is physically tampered with, for
example, that the cover is taken off one of the sensors. If the system
is armed, an alarm will occur. Your system will indicate this condition
to you by causing the Status button to light. Trouble beeps will start.
Press the Status button and the display shows “SN# Name
Tampered”. Correct the problem by resetting the sensor. If this
condition continues, call your security system dealer.
RF jam detected The panel receiver may be experiencing some interference. The
system will call to notify the central monitoring station about this
problem.
Clearing status Some types of status conditions, such as alarm history, must be
cleared manually. To clear system status, press Status, read and/or
listen to the status messages, and then press Disarm. If the trouble
condition was a low system battery, perform a sensor test. The Status
light should turn off if all trouble conditions have been corrected.
