ESL Smoke Sensor Model 562
Mounting Guidelines
Preliminary
ity roo, and hallways not protected by the required
smoke alarms. The installation of smoke alarms in
kitchens, attics (finished or unfinished), or garages is
not normally recommended, as these locations occa-
sionally experence conditions that can result in
improper operation.”
The above NFPA standards are a minimum
requirement for smoke sensor installation. For better
protection, we also require the installation of a smoke
sensor inside every bedroom in existing construction.
❑
DO NOT mount a smoke alarm to a drop ceiling tile;
mount it to a metal runner (see figure 2).
Figure 2. Smoke alarm mounted to drop ceiling.
❑
Mount all smoke alarms within 100 feet of the panel.
❑
Install a minimum of two smoke alarms in any house-
hold, no matter how small it is.
❑
Put a smoke alarm in the hallway outside of every bed-
room area. A minimum of two smoke alarms are
required in homes with two bedroom areas (see
figure 3).
A78-1171-02
Figure 3. Residence with multiple sleeping areas
❑
Put a smoke alarm on every level of a multi-level resi-
dence (see figure 4).
Figure 4. Multi-level residence
❑
Install basement alarms on the ceiling at the bottom of
the basement stairwell.
❑
Install smoke alarms on the ceiling as close to the cen-
ter of the room as possible. If this is not practical,
install it on the ceiling no closer than 4 inches (10 cm)
from any wall or corner (see figure 5).
❑
If ceiling mounting is not practical, install on an inside
wall between 4 and 6 inches (10 and 15 cm) from the
ceiling (see figure 5).
❑
Put smoke alarms at both ends of a bedroom hallway if
the hallway is more than 30 feet (9 meters) long. Large
rooms over 900 square feet require more than a single
sensor.
Figure 5. Smoke alarm mounting locations
❑
Areas with rough ceilings or short, transom-type walls
coming down from the ceiling require additional smoke
alarms.
❑
Install second-floor smoke alarms on the ceiling at the
top of the first-to-second floor stairwell. Be sure no
door or other obstruction blocks the path of smoke to
the unit.
❑
In rooms with sloped, peaked, or gabled ceilings,
install smoke alarms 3 feet (0.9 meter) measured down
on the slant from the highest point of the ceiling (see
figure 6).

Limitations
All alarms are subject to possible compromise or failure-to-
warn for a variety of reasons, for example:
❑
Smoke alarms cannot detect smoke in chimneys, walls,
roofs, or smoke blocked by a closed door.
❑
Alarms may not detect smoke on other levels of the
building.
