The alarm conversation in Modbury is really a conversation about brick. The suburb's 70s and 80s double-brick homes attenuate wireless signal between rooms, which is why the all-wireless kits sold on convenience develop mystery dropouts here — and why our designs start with on-site signal testing rather than a brochure. The other half of the design is the commuter rhythm: the O-Bahn empties these streets on weekday mornings and refills them at dusk, so the alarm protects an empty house for most of its working life and has to be effortless to arm on the way out the door. Hybrid wired-and-wireless design, detection placed where these floorplans funnel movement, and arming a commuting household will actually use.
Every double-brick Modbury home gets the same first step: wireless signal tested room by room, because internal masonry walls decide what's reliable and no two floorplans decide it the same way. The design that follows is hybrid — wired runs through the generous roof cavity where testing says the masonry wins, wireless where it's genuinely solid. Detection then goes where these 70s–80s floorplans funnel movement: the entry, the hallway spine, the family room — a handful of well-placed detectors covering every path through the house rather than a sensor per room padding an invoice.
A Modbury alarm spends its most important hours protecting a house whose owners are a bus ride away in the city. So the system is built for the commute: arm it from the phone on the interchange platform when someone forgot, get alerts that distinguish a delivery at the door from a detector tripping inside, and check status from the office without wondering. Backup batteries are sized for a real storm-season outage, because a panel that dies with the power protects nobody — least of all a household that won't be home until evening.
Housing stock this age comes with alarm stock to match — panels installed decades ago, keypads with unknown codes, sensors of unknown vintage left by previous owners. Before recommending anything new, we assess what's in the walls: the original cabling is often the most valuable part of an old system and frequently tests fine. A takeover — new panel, new detectors, existing wiring retained where it passes — delivers a current, phone-connected alarm without redoing work the house already contains. Where the old system genuinely isn't worth keeping, we'll say so plainly.
