- Individual dwellings units of two or more rooms in HMOs
Check that a Grade D system is adequate for the dwelling into which the system is being installed.
4. POSITIONING ALARMS
The locations must comply with applicable building regulations.
Hot smoke rises and spreads out, so a central ceiling position is the preferred location.
The air is “dead” and does not move in corners, therefore alarms must be mounted away
from corners. Place the unit:
- At least 300mm away from walls. See
Figure 1
.
- At least 300mm from any light fitting or decorative object which might obstruct smoke /
heat entering the alarm.
