Oh, alright. That’s something I would not expect Siemens to do though, especially given that they eventually shut down Faraday completely in 2018 according to this page on this very forum.
I believe they are fundamentally different, as the DPU is only used to set the address of 6000/7000 (8700 series) detectors and devices, while it can also program the loop number and device type of 1000/1500 (8800 series) modules. In other words, 8800 modules need to know the SLC loop their on and what they need to do in order to work, while 8700s either don’t need to or can get that info straight from the panel over the SLC.
As for brand ID, That’s definitely the case for 8700, FS250, and Siemens FD and FC panels. Faraday MPC 6000 and 7000 panels only work with Faraday 8700 devices, Siemens Cerberus FC panels work with both their own and Faraday 8700s on the same loop, and I’m pretty sure that Desigo FD series detectors only work on Desigo panels. Not sure if FD panels can use other devices. All those ARE the same protocol underneath.
The FireSeeker-100 and FireSeeker-250 use different protocols. Siemens had a special line of devices (e.g. FS-DP) for the FireSeeker-100 that was not used on the FireSeeker-250, but these devices look like the Faraday 8800 devices and the SLCs have the same device capacity. On the other hand, the FireSeeker-250 uses the same H-series devices as the FireFinder XLS, which I suspect are the 8700 devices (but with brand locking differences).
Tecumseh Tech mainly seemed concerned with servicing legacy systems, often those involving equipment from System Sensor (a competitor).
Alright I guess. Just saying though: doesn’t seem like something that Siemens would do, allowing part of a company they acquired to spin off & become successful without them.
