NeilHKH Posted January 19, 2021 Share Posted January 19, 2021 Panel has become unreliable and believe it is the panel not the wiring. I have 12 proximity sensors, 12 smoke detectors and 2 heat detectors. I also have 3 remote access keypads with simple LCD display. I would like to add another 6 sensors. My questions are: Should I reuse the existing wiring? (its an old house and took a great deal of effort to fit professionally). Which system would provide the most intuitive fault finding? Which system / manufacturer offers the most scope for the future? Can I reuse all the existing detectors? Would ideally like to be able to look in from a pc or iPad to see status? Any comments or suggestions gratefully received. Quote Link to comment Share on other sites More sharing options...
StuartSelfMon Posted January 20, 2021 Share Posted January 20, 2021 Most modern systems - Honeywell Galaxy, Texecom, Etc. have many zones capability with double balanced circuits. This means that you can detect open and short circuits on each sensor and get a detailed message from the panel to tell you what's going on. You can use existing wiring and sensors. For existing sensors, you just add a couple of resistors to the contacts to make them double balanced. Each active sensor only requires 3 cores and passive sensors 2 cores. You can also add zone expansion using RIO's (remote I/O) for situations where you have an existing wire going to a point (existing sensor say) and you want to expand to another 8 sensors in that area. I use the Honeywell Dimension 96 (providing up to 96 detection circuits and 48 outputs) in my own home with two active 115db backlit Texecom sirens, multiple keypads, a power RIO and regular RIO. I have the E080 Ethernet module and SelfMon automation module, so have phone/smart device apps and can control the heating, garage doors, gates and lighting in combination with Home Assistant. The Dimension has a nice big reliable linear power supply - I've never seen one of those go faulty - cannot say the same for Texecom's PSU's which were plagued with issues. Disclosure - I run the SelfMon self monitoring platform. Quote Link to comment Share on other sites More sharing options...
Secware_Tech6 Posted January 20, 2021 Share Posted January 20, 2021 As Stu really doubt there is a wiring issue, get your installer to test and reuse it. Always use a wire if you can. Quote Link to comment Share on other sites More sharing options...
NeilHKH Posted January 20, 2021 Author Share Posted January 20, 2021 StuartSelfMon. many thanks for your reply. Most helpful. Given me a good direction to explore. I believe strongly in wires as it is old house and wireless can be flaky. will report back when I work out what I need to buy. Quote Link to comment Share on other sites More sharing options...
