System Sensor P24 and S24 Strobe and Horn_Strobe - Manual (Page 3)

D900-25-00 3 I56-0981-001R
The horn/strobe or strobe will not work without power. The
horn/strobe gets its power from the fire/security panel monitoring the
alarm system. If power is cut off for any reason, the horn/strobe will not
provide the desired audio or visual warning.
The horn/strobe may not be heard. The loudness of the horn meets (or
exceeds) current Underwriters Laboratories’ standards. However, the horn
may not alert a sound sleeper or one who has recently used drugs or has
been drinking alcoholic beverages. The horn may not be heard if it is placed
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, machin-
ery or music appliances that may prevent alert persons from hearing the
alarm. The horn may not be heard by persons who are hearing impaired.
NOTE: Strobes must be powered continuously for horn operation.
The signal strobe may not be seen. The electronic visual warning signal uses an extremely reliable xenon flash tube. It flashes at least once every
second. The strobe must not be installed in direct sunlight or areas of high
light intensity (over 60 foot candles) where the visual flash might be dis-
regarded or not seen. The strobe may not be seen by the visually impaired.
The signal strobe may cause seizures. Individuals who have positive
photic response to visual stimuli with seizures, such as persons with
epilepsy, should avoid prolonged exposure to environments in which
strobe signals, including this strobe, are activated.
The signal strobe cannot operate from coded power supplies. Coded
power supplies produce interrupted power. The strobe must have an unin-
terrupted source of power in order to operate correctly. System Sensor rec-
ommends that the horn and signal strobe always be used in combination
so that the risks from any of the above limitations are minimized.
