Three-Year Limited Warranty
System Sensor warrants its enclosed smoke detector to be free from
defects in materials 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 this smoke detector. 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 repair or replacement of any part
of the smoke detector which is found to be defective in materials or work-
manship under normal use and service during the three year period com-
mencing 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, Repair
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 repair or 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 dam-
ages for breach of this or any other Warranty, expressed or implied what-
soever, 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.

Maintenance
NOTE: Before removing the detector cover, notify the
proper authorities that the smoke detector system
is undergoing maintenance, and therefore the sys-
tem will be temporarily out of service. Disable the
zone or system undergoing maintenance to prevent
unwanted alarms.
1. Remove the detector cover by placing a small-bladed
screwdriver in the side slot of the detector cover, twist-
ing it slightly until the cover can be turned counter-
clockwise for removal.
2. Vacuum the screen carefully without removing it. If fur-
ther cleaning is required, continue with step 3, other-
wise skip to step 6.
3. Remove the screen by pulling it straight out (see Figure
5). Vacuum the inside.
4. Clean the vaned chamber piece by vacuuming or blow-
ing out dust and particles.
5. To replace the screen, orient it so that the arrow on top
aligns with the test module socket of the detector.
Carefully push the screen onto the base, making sure it
fits tightly to the chamber.
6. Replace the cover by gently rotating it clockwise until it
locks in place.
7. Notify the proper authorities the system is back on line.
