Three-Year Limited Warranty

System Sensor warrants its enclosed product to be free from defects in materi-
als and workmanship under normal use and service for a period of three years
from date of manufacture. System Sensor makes no other express warranty
for the enclosed product. No agent, representative, dealer, or employee of the
Company has the authority to increase or alter the obligations or limitations
of this Warranty. The Company’s obligation of this Warranty shall be limited
to the replacement of any part of the product which is found to be defective
in materials or workmanship under normal use and service during the three
year period commencing with the date of manufacture. After phoning System
Sensor’s toll free number 800-SENSOR2 (736-7672) for a Return Authorization
number, send defective units postage prepaid to: System Sensor, Returns

Department, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please
include a note describing the malfunction and suspected cause of failure.
The Company shall not be obligated to replace units which are found to be
defective because of damage, unreasonable use, modifications, or alterations
occurring after the date of manufacture. In no case shall the Company be
liable for any consequential or incidental damages for breach of this or any
other Warranty, expressed or implied whatsoever, even if the loss or damage
is caused by the Company’s negligence or fault. Some states do not allow the
exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you. This Warranty gives you specific
legal rights, and you may also have other rights which vary from state to state.

The sounder and/or strobe will not work without power. The sounder/strobe

gets its power from the fire/security panel monitoring the alarm system. If power

is cut off for any reason, the sounder/strobe 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 or one who has recently used drugs or 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 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 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 occupants. 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 disregarded or not seen. The strobe may not be seen by the visually

impaired and is not intended to meet American Disabilities Act (ADA) requirements.
The signal strobe may cause seizures. Individuals who have positive photic re-

sponse 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 sup-

plies produce interrupted power. The strobe must have an uninterrupted source of dc

power in order to operate correctly. System Sensor recommends that the sounder and

signal strobe always be used in combination so that the risks from any of the above

limitations are minimized.
