1. Does NBES0307 smoke sensor is enabled for NBRK0750 ?
2. How many NBES0307 sensors will be able to handle the new NBRK0750 ?
Thank you in advance.

If you're unsure what sensors are supported by a specific unit, I suggest you keep the NetBotz compatibility chart link handy:
This document lists the different NetBotz appliances as well as all the supported sensors for each in a handy little chart.
Please note that there are no stated limits to the number of smoke sensors that you can connect to the NetBotz 750 but if you are connecting them to external sensor pod 150s, be sure to follow any recommendations on powering them. I believe the suggestion is one AP9505I power supply for every 4th pod.
Cory pointed out to me that unlike previous NetBotz hardware, the 750 is supposed to be able to handle the full complement of 150 pods without an external power supply. This is true however I feel more comfortable with a few extra power supplies if they were all using the smoke sensors.
Thanks @Andy! I don't have enough to test a full config. Also, did you check them with any of the devices in an alarm state? I believe they draw more which is why I considered that aspect in the 1st place.
Thanks again, Steve
I will test it some day later (office limitations). We have a request to integrate 3rd party sensors and it's more complicated than I expected 🙂 Anyway all what the sensor do is pulling signal (0) to +5 and I don't remember any significant changes in power consumption.
(In my case with NBWL0455) consumes 0.1ma @23v line (powered, no smoke)
and 17.3ma @23v (smoke detected) + 0.4ma @5v sensor line.
(probably no extra power needed typically but for fully loaded installations and long cables every extra 0.4 Watt in case of smoke detection may play a role. My another consideration is the power supplies those may lose their parameters with time. NetBotz equipment often work for years in hot conditions - capacitors in power supplies may give up quicker. So extra power won't be excessive and your recommendation in general is correct.)
