Limitations of Horns/Strobes
The horn and/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 may not be heard. The loudness of the horn meets (or exceeds) current Underwriters’ Laboratories standards. How-
ever, 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, machinery or music appliances that may prevent alert persons from hearing the
alarm. The horn may not be heard by persons who are hearing impaired.
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 three seconds and exceeds current Underwriters’ Laboratories standards for private mode viewing. The
visual warning signal is suitable for direct viewing and must be installed within an area where it can be seen by building occu-
pants. The strobe must not be installed in direct sunlight or areas of high light intensity (over 60 footcandles) where the visual
flash might be disregarded or not seen. The strobe may not be seen by the visually impaired and is not intended to meet Ameri-
can Disabilities Act (ADA) requirements.
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 uninterrupted source of DC power in order to operate correctly. System Sensor recommends that the horn and
signal strobe always be used in combination so that the risks from any of the above limitations are minimized.
