Notification Appliances—PS12/24ADA Series Signaling Strobe and Sounder 15
These signaling strobes and sounders are designed for installation in
accordance with NFPA-72-National Fire Alarm Code or equivalent codes
and standards applicable to the country of installation. Test your alarm
system per the applicable codes and standards specific to the location and
use of your facility.
●
The signaling strobes and sounders will not work without power. The
strobe/sounder gets its power from the fire/security panel monitoring
the alarm system. If power is cut off for any reason, the
strobe/sounder will not provide the desired audio or visual warning.
●
The sounder may not be heard. The loudness of the sounder meets or
exceeds current Underwriters Laboratories standards. However, the
sounder may not alert a sound sleeper, one who has recently used
drugs, or one who has been drinking alcoholic beverages. The
sounder 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 sounder may not be heard by persons who are hearing impaired.
●
The signaling 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 flashtube. 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 signaling 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 signaling strobe and sounder
be used in combination to minimize risk.
●
The signaling 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.
