I cannot arm my system and do not know why.

Several things can affect your ability to arm your system. The first place to look is your keypad. Is the green light lit on your keypad? If not see below. If it is on, are you using the correct code? Are you using the correct arming sequence? See below.

My keypad is displaying something I haven’t seen before.

Below are some commonly seen trouble conditions and a short explanation.
  • FC Indicates that a failure has occurred in the telephone communication portion of your system. Please test the system (see below) to see if service has been restored. Contact us for service.
  • For cellular service customers: Cellular service may be interrupted for short periods of time due to reasons such as cellular tower maintenance and, atmospheric interference.  Please test the system (see below) to see if service has been restored. Attempt the test again if unsuccessful after an hour.
  • BAT Indicates that a low system battery accompanied by "beeping" at the keypad. If this condition persists for more than one day (with AC present) Contact us for service.
  • Bat + Zone number Indicates that there is a low battery condition in the wireless transmitter on the zone displayed. Accompanied by a single "beep" (about once every 30 seconds) at the keypad. Either replace the battery yourself, or Contact us for service via the link to the left. If the battery is not replaced within 30 days, a CHECK display may occur.
  • No AC The system is operating on battery power only due to an AC power failure. If only some lights are out on the premises, check circuit breakers and fuses and reset or replace as necessary. If AC power cannot be restored and a “low system battery” message appears. Contact us for service.

How do I test my system?

Call the monitoring center at 678.482.7211. You will need to supply them with your account number and your password. Ask them to put your account on test for one hour. (Longer if you feel it is necessary. Be aware that the system will automatically come out of test at the end of this time; and while it is in test the monitoring center will not call anyone when they receive a signal.) Test your system by arming it, and then setting it off by opening a door/ window or walking through a motion area. Allow the siren to stay on for about 45 seconds and then turn the system off. Be sure to reset the system after you turn it off. Call the monitoring center and ask them what signals they have received. Once they have successfully received the signals, ask them to take your system out of test. If no signals were received send us a request for service (see the link to the left.) and we will schedule a service appointment with you. “FC” will appear on your keypad shortly. (See “My keypad is displaying something I haven’t seen before.” For more info.)

My system is beeping at me for no reason, what do I do?

To silence the beeping simply press any button. Or press in your code+1. Please note that the screen should be displaying a trouble condition on the keypad. Please take note of it and then see “My keypad is displaying something I haven’t seen before.”

How do I reset my system?

Enter the “OFF” sequence twice. (4 digit master code+1)

My system went off and no one called me, what’s up Doc?

You may have an issue with your communications method.
If you have traditional (AT&T) phone lines, check to see if your home phones are functional. If they are not unplug the phone connection located in the master control panel. And then check your house phones again. If you now have a dial tone, contact us using the request service link and we will schedule a service call with you. If there is no change contact your telephone service provider about the outage.
  • If you have VOIP phones (Comcast, Vonage, etc.) follow the steps above. Try the test a second time after about a half hour. Because of the nature of VOIP phones it may be that local bandwidth usage impaired the signal sent.
  • If you are using a Cellular/Radio communications method, try retesting after a half hour. If there is still no response contact us using the request service link and we will schedule a service call with you.

Is there somewhere that I can find the answers to my questions?

Your user manual is an excellent source of information on your system. It goes into much more detail than we have the space for in the Troubleshooting FAQs.  For your convenience we have included downloadable copies (PDF format) for the systems we offer.

The green light is not on, what causes this?

When a zone is not closed the green light will remain off until it has been closed. Push the *(star button) the keypad will then display the zone/s that are open. Check to be sure that the items on the zone are closed securely. If they appear to be shut securely and the light is still off, try opening and closing them again. Sometimes the item appears shut but is not shut all the way. (This is especially true of window contacts.) If the zone displayed is a Motion detector have everyone in the room standstill and check again. If none of these suggestions work, please contact us for service via the link at the left. We will then contact you to schedule your service call.
