Re: Simplex 4005, 4009 System Questions and Advice Needed

The first two cards are 4 point IDC cards. The third card is a 4 point NAC/relay card. Those three cards come with the panel as standard equipment. The fourth card looks like an 8 point I/O card. It can drive relays or annunciator lamps. It can also accept contact inputs. Each point can be programme...

Re: Simplex 4005, 4009 System Questions and Advice Needed

Power down should be in this order: remove positive battery terminal, shut off AC power, remove negative battery terminal. Negative battery should always be the last connection removed and the first connection at power up. There is no external programming software for a 4005. All the smarts are in t...

Re: What is the oldest system you have seen in operation?

What were the notification appliances? Bells? The system used horns. As I remember the ones at corridor ends were front projector types and along corridor walls they were dual projector types. The pull stations were a mixture of old and new as replacements were made over the years for various reaso...

Re: What is the oldest system you have seen in operation?

The oldest system I ever worked on was a 4245 in an elementary school in a small town. The data plate with the model and serial number was labeled International Business Machines. That places the manufacture year prior to 1958 which was the year Simplex bought that division of IBM. I am quite sure t...

Re: Simplex 4010 board

I did some on line research and found that the manufacturer did discontinue the TDA2040 chip. So the module is a circuit that replaces the chip that is no longer available. From a DIY audio forum: A sad day for 5 pin chip amps ST Microelectronics has discontinued the following parts: TDA2003 TDA2030...

Re: Simplex 4010 board

I have not seen one of those boards but I would leave it alone. That probably is a modification for performance improvement from an engineering change order. It could also be caused by the original part being no longer available from the vendor. If you remove the module the board probably will not w...

Re: Old Simplex System, Need Info

Obviously I can't be 100% sure without seeing the inside of the panel. However, I never saw a panel with the "AX" control module (Operating Power Trouble and Supervisory Power Trouble circuits) that did not use AC horns. The panel in the picture has the "AX" control module. Those panels used an "H" ...

Re: simplex 4006 strange trouble message.

I will take a stab at this. I programmed a zone on a 4006 and then removed the EOLR. Is this what you are seeing in the history log? SIG_SMI_DNT_B.png The top line is the point custom label. The lower line left is the point type. The lower line right is the point condition. If you scroll the zones i...

Re: Need Help for SIMPLEX 4100ES Signal Bypass.

OK, that helps. I will have to do just a little research.

Is this a plain general system or is there some special signaling programmed?

Re: Old Simplex System, Need Info

The Fan Disconnect could be used to test the system without cycling the air handling units off and on repeatedly. It also could be used to allow the units to restart to clear smoke out of a duct detector that went into alarm. Then the system could be reset. I installed some 4208 panels in my early y...

Re: Need Help for SIMPLEX 4100ES Signal Bypass.

If this is an audio system with speakers instead of horns and is running in default general alarm that should work for the speakers. It does not effect strobes. If there is custom audio programming, like fire floor, floor above, floor below more programming has to be done. If the system is using sta...

Re: Old Simplex System, Need Info

That is a 4208. According to the control module it is a 4208AX, which is the AC panel. It probably has series AC horn circuits. I can't be sure without seeing a picture of the inside. If the price is right and you like historic old panels it looks clean. How much you want it is up to you. I have a l...

Re: Simplex 4207/2100 voice

All of the 42XX documentation was distributed as printed materials. That was in the age of mainframe computers that filled entire rooms with equipment. Whatever documents survived were kept in someone's personal technical library. During those times all of the service acknowledgments I wrote were ma...
