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
