Positioning Alarms - Ei Electronics Ei2110e Series Instruction Manual

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 Alarm:
- 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.
Note: Ceiling mounting is recommended - do not wall mount Alarms.
Sloping Ceiling
In areas with sloping or peaked ceilings install the Alarm 900mm from the highest point
measured horizontally (see Figure 2). This is because "dead air" at the apex may
prevent smoke from reaching the Alarm.
