Notification Appliances—E Series Speakers and Strobe Speakers 11
Installation Procedures
!
WARNING:
Personal injury hazard. Under certain circumstances, the
use of multiple strobes within a person’s field of view, and
strobe reflections in a glass or mirrored surface might induce
a photosensitive response in persons with epilepsy.
To minimize this possible hazard, Johnson Controls strongly recommends that the number
of strobes installed within a single room, hallway, or other field of vision not exceed the
parameters prescribed by the
NFPA-72-National Fire Alarm Code and UL standards.
Johnson Controls strongly recommends the intensity and flash rates of such strobes not
exceed those levels established by applicable laws, standards, regulations, and guidelines.
The number of installed strobes should not present a composite flash rate in the field of
view which exceeds five hertz at the operating voltage of the strobes.
Note:
NFPA 72 and ANSI 117.1 Standards provide means for determining equivalent
illumination using fewer, higher intensity strobes within the same protected area.
Installation of strobe products in sleeping areas should be wall mounted as follows:
1.
The on-axis (directly in front of lens) light output should be directed at the eyelids of
the sleeping person, such as the pillow end of bed, or the bed head.
2.
No part of the bed shall be more than 16 feet from the strobe notification appliance.
!
WARNING:
Personal injury hazard. Installers must advise owners and
operators of buildings with sleeping occupants to warn
guests, residents, and employees not to move the bed location
to a position violating Points 1 and 2 above or serious injury
and/or loss of life may occur during a fire emergency.
!
WARNINGS:
Personal injury hazard. When installing strobes in an open
office or other area containing partitions or other viewing
obstructions, ensure the strobes operating effect can be seen
by all intended viewers. The intensity, number, and type of
strobes must alert the viewer, regardless of the viewer’s
orientation.
!
WARNINGS:
Personal injury hazard. NFPA-72-National Fire Alarm
Code requires supervision of notification appliance circuits.
Check if unsupervised circuits violate any applicable codes.
