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 ft. (4.88m) of the pillow.
SUPPLEMENTARY VISIBLE SIGNAL
The strobe may be located less than 80" (2 m) 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 interconnect-
ing 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 ones
ability to notice the strobe light.
• In areas where the temperature may fall below 32˚F (4.4˚C) or rise above 100˚F
(37.8˚C).
• In areas with high humidity.
