Install all the other Smoke Alarms similarly.
Tamperproofing the Smoke Alarms
The Alarm can be made tamperproof to prevent unauthorised

Break off the small pillar on the base as shown in figure 8a.
To remove the Alarm from the ceiling it is now necessary to
use a small screwdriver. To release the Alarm, push the catch
towards the ceiling and then twist off (see figure 8b).
