NEW In Siemens SEALEDBox (The MMB-3 is in an Original Sealed Siemens Package, thus no photo!) MMB-3 Enhanced "Fast Processor" for the MXL Fire Alarm System. Siemens has indicated that they are nearing the ending of production of the MXL MMB Chip Sets (productline is20+ years old!). They have used the Faster Processor Chip Sets (MMB-3) to received UL864 and Ninth Edition. If your polling loop is slow, considering "splitting nodes" and the likes....maybe now is the time to upgrade your MMB-1 or MMB-2 to the MMB-3 Enhanced Processor (see first link below from Siemens for more details!). Once these processors are GONE....you are out of luck. Having one or two of these (if you are a large user) as Spares Stock is like money in the bank.
If f you are in a Fire Command Center and you don't have the Retrofit Wall Space for more Panels/Controls...You ARE out of Luck :-( !!!....which means MAJOR RETROFIT to go from old devices (FP-11 to HFP-11 "H"=High Speed, TRI-R to HTRI-R, TRI-D to HTRI-D, and so on!). Major Money and Upgrades required when you can no longer get MMB-3 Main Mother Boards! Think Ahead, and Prepare! When they are gone, you are plainly out of luck!
Don't wait to have your unit repaired when it fails, have a hot stand by on your shelf at a reasonable align="left">The MMB-3 uses a new, faster processor that is approximately eight times faster than the previous processor, and it has more memory as well.
