OK thanks so much

Hi thanks a lot! It should indeed be possible to for them to find the fault, but as it's a 14+ year SAV-wire system with a panel model that was around in 2008, so my fire engineer company says "all the devices have surpassed their recommended replacement dates and so need to be replaced anyway". And they says if I "upgrade" to TwinFlex then future fault diagnoses/repair should be quicker and thereore cheaper than my current (Haes envoy panel with Apollo s65 detectors) system. I do wonder if they'll say the same thing in 10 years time about the TwinFlex though ...! Thought? Btw, I wouldn't want to recable because the wiring is neatly embedded and rewiring completely no doubt involves a lot of ugly trunking inside the flats and massive increase in work/cost. (This is assuming there's no cable fault at present, but even if there is it's only 1 zone.)

Engineer says Fike TwinFlex Pro devices do indicate faults on each device via flashing LED, which means when they panel says something is wrong, then it's simpler to work out which exact device is the correct one. Basically, it's the best way to get simpler diagnostics of future faults without rewiring when compared the the current sav-wire system. Is that not so?

Hi for a residential house converted 30+ years ago to 8 self-contained flats (7 studios, one 1-bedroom). It has a 14 year old system with Haes Envoy panel programmed to a twin-wire/ sav-wire apollo-65 series bases/detectors/sounders. There's 4 zones, heat detectors in each flat, and smokes in the hallways all connected to the panel. Each flat has a stand-alone mains-powered smoke alarm. In the past year or two, 2 zones have developed a fault and diagnosing was tricky as it's trial an error checking each device on the zone. Ideally I'd like a system where it's possible to see on each device if it's faulty. My fire engineer quoted £2500 to replace the panel, all detectors/sounders and call points to TwinFlex (presumably Fike) as that would show via blinking-LEDs which device is playing up, but that's above my current budget. Is there a simpler and cheaper route that would keep most of the existing detectors e.g. just replacing the panel with a Kentec Sigma? Or for that matter does an Apollo AlarmSense system allow individual devices to indicate which is faulty? thanks, Ash
