20 Notification Appliances—E Series Speakers and Strobe Speakers
Test your alarm system per the applicable codes and standards specific to the location and
use of your facility.
The audible device and/or strobe will not work without power. The audible device/strobe
gets its power from the fire/security panel monitoring the alarm system. If power is cut
off for any reason, the audible device/strobe will not provide the desired audio or visual
warning.
The audible device may not be heard. The loudness of the audible device meets or
exceeds current Underwriters Laboratories standards. However, the audible device may
not alert a sound sleeper, one who has recently used drugs, or one who has been drinking
alcoholic beverages. The audible device may not be heard if it is placed on a different
floor from the person in hazard, or if it is placed too far away to be heard over ambient
noise such as traffic, air conditioners, machinery, or music appliances that may prevent
alert persons from hearing the alarm. The audible device may not be heard by persons
who are hearing impaired.
The signal strobe may not be seen. The electronic visual warning signal that flashes at
least once every three seconds meets or exceeds current Underwriters Laboratories
Standard 1971, and uses an extremely reliable xenon flash tube. The visual warning
signal is suitable for direct viewing and must be installed within an area where it can be
seen by building occupants. The strobe must not be installed in direct sunlight or in areas
of high light intensity (over 60 foot candles) where the visual flash might be disregarded
or not seen. The strobe may not be seen by the visually impaired.
The signal strobe may cause seizures. Individuals who have a positive photic response to
visual stimuli with seizures, such as epileptics, should avoid prolonged exposure to
environments in which strobe signals, including this strobe, are activated.
Johnson Controls recommends that the sounder and signal strobe be used in combination
to minimize risk.
The signal strobe cannot operate from coded power supplies. Coded power supplies
produce interrupted power. The strobe must have an uninterrupted source of DC power
in order to operate correctly.
