Hi,
I'm trying to add combination Smoke/CO (COSMO-4W or COSMO-2W) to my current system of 4-wire smoke detectors (4WT-B), but I still have a number of questions after reading the docs from System Sensor.
Current System:
- 4WT-B smoke/thermal detectors
- 3 independent 4-wire loops (basement, 1st floor, 2nd floor).
- mechanical thermal detector in the kitchen (connected to the 1st floor 4-wire loop)
Upgrade Questions:
- My first though was to use a COSMO-4W detectors along w/ the COSMOD-4W module (given the current 4W wiring). However, since I have 3-independent loops, this means 3 COSMOD-4W modules, correct?
- However, based on the documentation, I believe that I'm unable to re-use any of my 4WT-B detectors w/ the COSMOD-4W sensor. All would have to be upgraded to the 4WTA-B or 2WTA-B, correct?
- It seems like that 2W system offers more features by monitoring additional trouble and maintenance conditions on the trouble zone that aren't possible to monitor w/ the 4W system. If so, what are the advantages w/ staying w/ the 4W-based system? I think I can also wire everything in one zone w/ the 2W system as I can use the other two conductors as a return path.
- If I go switch to the 2W system, am I unable to wire the mechanical thermal detector in the kitchen; as the 2W loops cannot have mechanical thermal detectors on them. How do I wire that detector then?
- If I go w/ the 2W system, should I use the other conductors to create a "LOOP STYLE D / CLASS A WIRING"? What would be the advantage of having that?
Thanks for the advice.
