Error Codes

Troubleshooting

 

Display Meaning
FAULT FAULT displayed with ZONE NUMBER(S) (ie: FAULT 02) means that there is a problem with that ZONE.  Think of a ZONE as a device.  The number shown indicates a door/window/sensor.
WHAT TO DO - Have them try to clear the code by entering their 4 digit code and pressing the OFF button.  Check that all doors and windows are closed or have the customer open and close ALL windows and doors with sensors on them.  Have the customer visually inspect for conditions that could set-off a sensor (ie: flooded basement, movement in front of a motion detector) or possible damage to the sensors.  If it is a smoke/carbon monoxide sensor then it is considered a LIFE SAFETY device.  If it is during regular business hours issue a TT (billable) and we will respond as soon as possible.  If it is AFTER HOURS then it is up to the customer if they would like to pay for an AFTER HOURS TRUCK ROLL. 
FAULT 103 -PANEL (alarm brain) lost contact with communications module (GSM = cell phone back-up or internet communications)
-GSM unit was tampered with (ie: cover removed)
-Primary or Secondary communications failure (ie: dial-up = primary, GSM = secondary)
-GSM unit is not registered/account not activated (It's just like a cell phone)
-Primary power loss
-Battery charger failure or low battery
WHAT TO DO: Issue a TT (billable), troubleshooting this error is beyond what the help desk can do. LIFE SAFETY RULES MAY APPLY.
 
LOW BAT Low system back-up battery
WHAT TO DO - This code will result in the customer being notified by the CENTRAL STATION but only between the hours of 8am to 10pm CT.  From 10pm to 8am the customer will not be notified, troubleshoot as follows.  If AC is not displayed on the panel have them check that the power adapter is plugged in.  Have the customer verify that the power outlet is working properly by plugging another device into the outlet.  If AC and LOW BAT are displayed have the customer enter their 4 digit code and press the OFF button.  If the condition does not clear, issue a TT (billable).  
 
Low Bat w/ Zone # Low battery in the SENSOR of the displayed ZONE (door sensor, window sensor, motion detector, ie: LOW BAT 02)
WHAT TO DO - Locate the SENSOR the ZONE is referring to (use plant information from CSI).  The customer will need to replace the battery in that sensor.  They can use the instructions for that sensor found in their security folder to find the type of battery and instructions on how to replace it. If the customer is not comfortable replacing the battery we can issue a TT (billable).  If the displayed ZONE is 00 then a WIRELESS KEYPAD needs to have the battery replaced.  Customers should have at least a week from when the sensor begins to show low battery until it dies.  If the sensor is allowed to die. LIFE SAFETY RULES MAY APPLY.
 
bF Back-up Communication failure.  The GSM/Internet Alarmnet Backup unit has failed.
WHAT TO DO - Issue a TT (billable).  LIFE SAFETY RULES MAY APPLY.
 
CA Alarm has been triggered. 
WHAT TO DO - DISARMING system again should clear the code.  If it persists, and a correct disarming (4 digit code followed by the off key) should remove it.  If it refuses to be removed by disarming the system we may need to issue a TT (billable).  LIFE SAFETY RULES MAY APPLY only if you cannot get this message to remove.
 
CC The PANEL is communicating with the CENTRAL STATION or NEX-TECH.
WHAT TO DO - Nothing, this is normal.  The only reason to be worried about it is if it happens very often and for long periods of time.
 
dl The system is in STANDBY.  Displayed upon POWER UP for one minute. 
WHAT TO DO - If dl is displayed longer than 3 minutes, have the customer unplug the AC POWER ADAPTER and then plug it back in.   Press [#] and [0] at the same time once dl is displayed again.  DO NOT PRESS [#] [0] before dl is displayed.  If this fails, issue TT.  
 
EA "Exit Alarm", a DOOR/WINDOW/SENSOR was "FAULTED"  (Left open or set-off during the EXIT DELAY)
WHAT TO DO - If they haven't already done so, have the customer DISARM the system by entering the 4 digit code and press off.  They might have unknowingly set the alarm off.  Have them then RE-ARM the system, OPEN and CLOSE a door.  Then DISARM the system.  This should clear the error if done correctly.  If not we may need to issue a TT.
 
FC Communication failure, will only clear the next time the system is armed
WHAT TO DO - Have the customer check a landline for dial tone.  If dial tone is not present then either the ALARM PANEL has control of the line or there is trouble with the POTS or VoIP.  Have the customer try to locate the RJ-31X.  It will look like a phone jack with an RJ45 type connector plugged into it.  Have them disconnect the RJ45 connector from the RJ-31X.  If dialtone returns, and FC is still displayed, issue TT for BB.  If dial tone does not return the problem is not in the panel, it is in the line, issue TT for OUTSIDE PLANT TECHNICIANS.  LIFE SAFETY RULES MAY APPLY.
 
90 Radio frequency interference or jamming detected (300 Mhz range)
WHAT TO DO - Due to the frequency range this is either caused by another wireless alarm system or a HAM radio.  Issue TT. LIFE SAFETY RULES MAY APPLY
 
No Display Power Failure.  LEDs not lit.  System inoperative.  If the display is lit and the AC is not showing then the system is operating on battery power only.  Display and LEDs may flicker in this state.  If the customer has been without power for longer than 8 hours the back-up battery will be fully depleted.
WHAT TO DO - Have the customer check that the AC POWER ADAPTER is plugged in.  Have the customer verify that the power outlet is working properly by plugging another device into the outlet.  If the outlet is working but AC does not show in the panel display when plugged in, the panel is not receiving power.  Issue TT.  LIFE SAFETY RULES MAY APPLY.
