With around 996 residents per square kilometre, Donvale properties frequently have a separate wing or a converted space that the original alarm layout never covered. At about 22 kilometres out, Donvale sits in the belt where the common finding is two or three alarms of different ages, none of them talking to each other.
For Donvale, Manningham has no role in this. The standard is AS 3786 for the alarm and the building regulations for placement, and that is what we install to. A job in Donvale usually sits alongside something we already have booked in Blackburn North or Doncaster East that week.
12644 residents at the 2021 census, about 12.7 square kilometres, postcode 3111: that is the scale of Donvale within Manningham. Around Donvale our regular territory covers Blackburn North, Doncaster East, Mitcham and Nunawading. Nothing about a booking here is treated as out of area.
From our Boronia workshop Donvale is about 12.1 kilometres north-west, which is a short enough run that we can usually fit a look-in around another job rather than making it a separate trip.
