Can a Silent Knight system support 240 Addressable smokes as well as additional smoke and pull stations?

If not, what would you recommend?

Thank you

It would depend on the panel you’re looking at. With the right expansion modules the 5820XL could definitely accommodate all of that. You might also want to look at the Farenhyt/Silent Knight IFP-1000 if your distributor carries those.

Thank you I usually use ADI and they dont carry it, but if it that much better, I would hunt it down.
Why do you recommend using that?

I would be replacing an Siemens system that is falling apart. I would need about:
240 addressable smoke detectors
13 addressable heat
18 addressable manual pull stations
7 duct smoke detectors
2 water flow

Thank you

Bear in mind that I am not a technician, however I am getting this information of the 5820XL’s datasheet. You’ll also want to consult with your distributor as well as one of the technicians on this board once they respond.

From the datasheet:

[quote] Built in support for 99 SK detectors and 99 SK modules, expandable to 396 SK detectors and 396 SK modules using System Sensor protocol [/quote]

For that expansion, you’d need a 5815XL expansion module, which will provide you with additional SLC support, though whether or not you will need multiple is beyond my knowledge.
Assuming you’re using the SK protocol (the newer System Sensor one, used on detectors like the SK-PHOTO smokes, SK-HEAT heats, and modules like the SK-PULL-DA pull stations and SK-MONITOR monitor modules), if you maxed out the system to 396 modules and 396 detectors, in total you’d use:
[list]

  • [*]260 detectors (smokes, heats, ducts)
  • [*]9 modules (pulls, waterflows)
    • [/list] which should be plenty of addressable points for your installation. If your distributor carries the 5820XL, that's definitely an option. However, as I stated before, I am [i]not [/i]a technician, and I will gladly defer to the knowledge of a tech.

    If you have any further questions, feel free to ask them!

    assuming you have an mxl that’s falling apart and no longer manufactured, you can migrate to an xls system and keep your existing field devices and replace them all at a later date. might be a cheaper/better option to get a new head end now and worry about the rest later, instead of replacing it all today.

    I agree with Chris+s, that upgrading the panel to a new model that is backwards compatible with your existing field devices could be your most economical path. If you were asking about an older Simplex system upgrading only the panel would be my suggestion.

    Another item that has not been considered. If you replace the entire system (panel and field devices), the fire marshal may require you to bring the system up to current code. That can add to your bottom line cost. Most fire marshal offices will allow replacing only a failing panel with a new more reliable unit without upgrading the entire building.

    I also moved the topic to the help forum.
