FAQS (Frequently asked questions)


GE Caddx NX-8 Control Panel


1.      I do not have a green (status) light. What does this mean?

If you do not have a green light, a slow flashing zone light should be on, this will give you a more specific area to check for an open door or window. Once you have secured the area, you should get a green light. It is very important that you check ALL doors and windows. Many times our service department responds only to find a window or door that is open. Please check all doors and windows even if you normally never enter a room or open that door or window.


2.      My power light is flashing, what does this mean?

This indicates you have a Low Battery condition. (This is the main control panel battery)

If you have a Low Battery, you may either stop in our office to purchase a battery and install it yourself, or you call our office to schedule a service call.


2.   My service light is on. What does this mean?

This can mean several things; the most common is a low battery condition.

To find what type of trouble exists on the alarm, press *2, then observe the zone lights (1 thru 8), these lights will light for several seconds which will indicate what type of trouble exists on the alarm system. Follow the list below to determine the trouble type.

Zone 1 light = System fault (if this light comes on, press 1, then observe what light comes on and see chart directly below.

            Zone 1 light = Over Current Fault

            Zone 2 light = Siren Trouble

            Zone 3 light = Box Tamper

            Zone 4 light = Expander Power

Zone 5 light = Expander Low Battery

Zone 6 light = Expander Box Tamper

Zone 7 light = Expander Trouble

Zone 8 light = Ground Fault

Zone 2 light = Zone Tamper (If this light is on, press 2 and observe which zone is affected)

Zone 3 light = Zone Low Battery (If this light is on, press 3 and observe which zone is affected)

Zone 4 light = Zone Loss of Supervision (If this light is on, press 4 and observe which zone is affected)

Zone 5 light = Zone Trouble (If this light is on, press 5 and observe which zone is affected)

Zone 6 light = Telephone Fault (If this light is on, press 6; if zone 6 lights, phone line out of service – if zone 7 lights, aux communication failure)

Zone 7 light = Failure to communicate

Zone 8 light = Loss of System Time


If you have received a Failure to communicate, you may call our Central Station to place your system on test and force a test to our office, once this is received, the trouble light should clear.

If you receive a Fire Circuit Trouble, this will normally always require a service call.

If you receive a Loss of Time, this happens after a total power outage, including Battery Back-up. If this happens, follow these steps.

Setting Current Time = *97 Master Code then enter the current time (in 24 Hour Clock mode, also known as Military Time).
