AES IntelliNet 7788F-C RF , 7794 & 7750-F8 Wireless fire radio FAQ

    This is the most common questions I get asked everyday so I decided to write-up this simple often asked questions post to help educate technicians on these units. If you have more questions leave me a comment and I will respond ASAP 

How many goods do i need to pass a fire inspection in Texas ?
2 goods least.


Where can i find out what the status lights mean ?  


For the 7750-F8 AES radio look on page 11 for the 7788 ULP AES radio see section 3.8 of the manual.


Is this signal coming from the radio or the Intellitap/Intellipro ?


Have your central station Check their raw data for the signal if the raw data code starts with a 11 then it’s from the radio if it starts with a 13 then it’s from a full data module. Also the AES units normally only generate and e140 code when the onboard zones are tripped. 


Why am i getting troubles on zones 1 thru 8 all the time ?

 7750 Fire Radios must have power going to the zone card. If not we will get troubles from all 8 zones and we will not get any fire alarms from the radio.If the resistors are missing from any AES radio that will also generate trouble signals on all 8 zones.


 What does zone 10 mean from a AES radio ?

E370 on Zone 10 or E370 C010 is reporting a ground fault. A connection on a G terminal of the 7744F or 7788F is less than 100 Ohms to the Subscribers Battery Ground. On a Subscriber, battery and Earth ground are the same


 What does loss central plg mean ?

 That means a communication time out restore. The only time you should see that signal is in raw data. If you see it in Manitou the wrong template is being used for that aes account.


 What receiver # does the tap have to dial to turn on ? ?  

 The intelitap & intelipro are activated when the alarm panel dialer dials 555


When polling a radio why does it sometimes not give results or takes a long time to show results ?


When polling a radio and you wait a while and never get any results that means we can communicate with the radio.. but it can’t respond clearly back to us. Sometimes the poll results can take 3 to 5 mins but if they take longer than that radio will have  issues talking to us.


Can you remotely program my aes radio ?
If you have the 7750-F8 it can be programed  remotely if it’s a 7788 it can be programed  remotely Only if the tech is onsite and enables the remote programming with a programmer.
Why is my radio sending Status P140 signals?
That indicates an open zone that has not been restored. That’s usually caused by that zone being shorted. If that’s not the case then it will require other Advanced troubleshooting solutions.
What is a E370 signal ?That is a signal that is left open and has not restored. Usually caused by missing resistors.
 What is a zone 9 from the radio ?A zone 9 in a 7788 indicates a charging circuit fault. Please check the battery leads on the subscriber to make sure that they are reading between 13.6 and 13.8 volts. If you are reading less voltage than this please make sure that the transformer is the correct voltage. IF that is OK as well, you may need to replace the battery.
  • Great post!!!!! Do you work for an ASC or a CS?

    • Thank you for your comment I’m not that good at blogging vs dealing with aes units. I work in a Central Station
