Installing an alarm in a new build is the opportunity to integrate a high-performance system at lower cost. The key: anticipate pre-wiring.

1. Anticipate from the plans

Include the alarm in the specifications before partitions. See new-build finishes.

2. Wired versus wireless

Wired offers reliability and lifespan; wireless remains flexible but requires batteries.

3. Budget and installers

Budget €1,500 to €4,500 for a complete system, central connection included. See the new build Brussels market.

Questions about alarms in new builds

When to integrate the alarm into the site?
Ideally during electrical pre-wiring, before partition installation. This avoids costly later channelling.
Wired or wireless alarm?
Wired is more reliable and discreet but must be anticipated. Wireless remains possible in renovation or as a complement.
