sixwheeledbeast Posted August 24, 2019 Share Posted August 24, 2019 Contacts have limited use for detecting a break in, they are mandatory for making sure the numpties shut all the doors. Quote Link to comment Share on other sites More sharing options...

Eugene's DIY Den Posted August 24, 2019 Author Share Posted August 24, 2019 I notice since I installed my new SW 10-70 panel, I haven't had any false alarms. Separate tampers for each zone, so the sum of series resistances is less (11 sensors plus junction boxes, bell box, keypads etc). Maybe the immunity against transients spikes and bad connections due to tarnished tamper connections in junction boxes is better?

datadiffusion Posted August 24, 2019 Share Posted August 24, 2019 True story this, today after 3 years in storage we wheeled out our (new at the time) Bosch dishwasher and said goodbye to the crappy built-in one that came with the house. To my annoyance, it went into error 5 minutes after every cycle, even though it had been cleaned and drained before we moved. What was it? The flow switch uses an externally mounted reed over a sealed into the main water jacket rotating wheel with magnet. Jammed shut. Mild percussion maintainance fixed the machine Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment Share on other sites More sharing options...

Updates allow you to use some new devices that come out and fix any issues , although mostly I only needed to update for devices , firmware seems stable otherwise Yes, I'm in Ireland. I presume firmware upgrades can be installed via an RS232 serial connection to a laptop or similar, but you have to be a professional installer to download them from the manufacturer's website. I'm curious though what constitutes an alarm condition on a sensor. I.e how long contacts have to be open in order to trigger the panel. If this was relatively long, it could make the panel more immune to transients. A magnetic contact/ PIR contact would probably open for 100ms. A transient could be shorter, but the software might detect it if it's scanning everything rapidly. On a couple of occasions with my old panel, a zone triggered with the panel armed when I pulled out a mains plug. The alarm cable was quite close to the mains cable though.
