10 Notification Appliances—PA400 Electronic Mini-Sounders and PS12/24 Series Optional Strobes
The appliances must be tested after installation. Refer to the control panel
manufacturer’s test procedure. This sounder and signal strobes are
designed for installation in accordance with the NFPA Standard 72-
National Fire Alarm Code, or equivalent codes and standards applicable to
the country of installation.
●
Sounder and signal strobes are designed to provide fire and security
hazard warnings.
●
The strobe is for supplementary signaling use only.
●
The sounder or sounder/strobe combination will not work without
power. The sounder or sounder/strobe gets its power from the fire or
security panel monitoring the alarm system. If power is cut off for
any reason, the sounder or sounder/strobe combination will not
provide the desired audible or visual warning.
●
The sounder may not be heard. 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 in an area which is isolated by a closed door, if it is located on
a different floor from the person in hazard, or if placed too far away to
be heard over the 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 signal strobe may not be seen. The electronic visual warning
signal meets or exceeds current Underwriters Laboratories
Standard 1638. The visual warning signal is suitable for direct
viewing, and it 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.
