Kidde SLED177i - Manual (Page 4)

The following diagram shows that the light intensity gradually decreases as the
viewing angle is increased. Use this information to determine the best location
for the strobe light.
2. APPLICATIONS
PRIMARY DIRECT AND INDIRECT VISIBLE SIGNAL
Locate the strobe light on the ceiling in the center of the room or on
the wall a minimum of 80"(2 m) above the floor.
For rooms larger than 250 sq. ft. (14 ft. by 16 ft. - 4.27m by 4.88 m) the
notification device should be located within 16 feet of the pillow when located in a
sleeping area.
SUPPLEMENTARY VISIBLE SIGNAL
The strobe must be located more than 30 inches above the floor.
3. RECOMMENDED LOCATIONS OF VISUAL SIGNALING DEVICES
• Locate the first strobe light in the bedroom in which the hearing impaired
individual sleeps. If the bedroom door is kept closed at night, an
interconnecting smoke detector must also be installed in that bedroom.
• Locate additional strobe lights in any lived-in room where a hearing impaired
individual would need to be notified of an alarm condition.
4. LOCATIONS TO AVOID
• In direct sunlight or high ambient light areas; the bright light may reduce one’s
ability to notice the strobe light.
• In areas where the temperature may fall below 0°C (32°F) or rise above 49°C (120°F).
• In areas with high humidity.
• Do not use outdoors (This device is not listed for outdoor use).
