FIGURE I
e. The test knob is not an electrical switch, nor is it connected in any way to the
alarm horn. Therefore, when you test with the test knob, you are simulating the
smoke condition in the detector and testing all elements of the smoke detector
that are necessary for the detection of actual smoke. To check for proper smoke
entry into your smoke detector's sensing chamber, Gentex recommends using the
Home Safeguard Smoke Detector spray or CHEKKIT® SMOKE Detector Tester
from SDI. This test should be performed once a year and should be sprayed from
a distance no closer than 12 inches from smoke detector (refer to NFPA 72 for
details).
3. A trouble buzzer will sound if any detector is removed from its socket in supervised
circuits. CAUTION: When a smoke detector is removed it may cause other smoke
detectors to have a loss of power and become inoperative. If this happens,
reconnect the smoke detector until a replacement can be installed, or use a jumper
plug which can be ordered separately from the factory.
4. Power-On- Alarm Light. The LED on the face of the smoke detector blinks every
15-30 seconds, indicating electrical power is being supplied, see FIGURE I. If the
smoke (or test knob) persists for about 20 seconds, the LED will be on continuously
for latching models or flash rapidly for non-latching models to indicate the alarm
condition of the smoke detector. It will stay on until the system is reset.
MAINTENANCE
After your smoke detector has been in operation for a period of time or if it was
installed prior to the completion of all building construction, your smoke detector may
have become more sensitive due to dirt build-up in the smoke detector's optic sensing
chamber. This could cause nuisance alarms or cause the smoke detector to activate
from small amounts of smoke build-up. If this should occur, following this simple
washing procedure will restore your smoke detector back to its original condition.
For further information regarding frequency of maintenance and testing, refer to
NFPA 72, NFPA, Batterymarch Park, Quincy, MA 02269.
NOTICE: FAILURE TO FOLLOW FULL CLEANING INSTRUCTIONS COULD
RESULT IN DAMAGE TO THIS SMOKE DETECTOR.
1. Turn off electrical power to the detector.
2. Twist the smoke detector counter-clockwise to remove it from its mounting plate.
The fire alarm system shall remain active during all
maintenance. Therefore, while servicing one smoke detector, either use a
replacement smoke detector or jumper plug to keep the fire alarm system
operative. Contact your local Gentex distributor for the proper jumper plugs to
use with your fire system.
3. Unplug the connector from the back of the smoke detector. Do not remove the wire
connection; leave the connector for your replacement smoke detector or jumper plug.
4. Select three (3) standard size wash buckets and fill them each with one gallon of
normal tap water (distilled or de-ionized treated water is recommended as a final
rinse if water is extremely hard in your area).
5. Add 1/8 cup of Ivory® dishwashing liquid to the first bucket of water and allow it to
mix thoroughly, then place dirty smoke detector in the soap water mixture until it
becomes completely covered or submerged. NOTE: If the smoke detectors are
exceptionally dirty, you may wish to first wipe off any excess dirt before washing
smoke detector so as not to dirty the wash water too quickly.
DO NOT open smoke alarm for cleaning. IF SMOKE ALARM IS
OPENED DURING CLEANING, PRODUCT WARRANTY BECOMES VOID.
For a period of 24 months from the date of purchase, or a maximum of 20 months from the date of manufacture,
Gentex warrants to you, the original consumer purchaser, that your Smoke Detector will be free from defects in
workmanship, materials, and construction under normal use and service. If a defect in workmanship, materials, or
construction should cause your Smoke Detector to become inoperable within the warranty period, Gentex will repair
your Smoke Detector or furnish you with a new or rebuilt replacement Smoke Detector without charge to you except
for postage required to return the Smoke Detector to us. Your repaired or replacement Smoke Detector will be
returned to you free of charge and it will be covered under this warranty for the balance of the warranty period.
This warranty is void if our inspection of your Smoke Detector shows that the damage or failure was caused by
abuse, misuse, abnormal usage, faulty installation, improper maintenance, or repairs other than those performed by
us. ANY WARRANTIES IMPLIED UNDER ANY STATE LAW, INCLUDING IMPLIED WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, APPLY ONLY FOR THE WARRANTY
PERIOD SPECIFIED ABOVE. PLEASE NOTE THAT SOME STATES DO NOT ALLOW LIMITATIONS ON HOW
LONG AN IMPLIED WARRANTY LASTS, SO THE ABOVE EXCLUSION MAY NOT APPLY TO YOU.

NOTICE: ONLY IVORY® DISHWASHING LIQUID IS TO BE USED. OTHER BRANDS
ARE NOT RECOMMENDED AND MAY CAUSE YOUR DETECTOR TO
MALFUNCTION.
6. Allow smoke detector to soak for approximately 10 minutes (longer if extremely
dirty). Then agitate for 5 or 10 seconds to flush out any remaining dirt left inside
detector's housing.
7. Remove detector from wash water and transfer directly to one of the first rinse
buckets containing clear water. Again, allowing smoke detector to become
completely submerged, agitate once more for 5 or 10 seconds to remove soap
residue.
8. Finally, transfer detector to your second and final rinse bucket, repeating method
found in Step 7, then remove smoke detector to a clean dry area for a period of 48
hours to allow it to thoroughly dry.
IMPORTANT: It is recommended to change wash and rinse water after five (5) smoke
alarms. If your devices are extremely dirty, water should be changed more frequently.
NOTICE: SMOKE DETECTORS ARE TO AIR DRY ONLY. DO NOT PLACE SMOKE
DETECTOR IN OVEN OR USE A HOT AIR BLOWER TO ACCELERATE DRYING
TIME. THIS COULD RESULT IN DAMAGE TO YOUR SMOKE DETECTOR.
In the event you experience difficulty in the cleaning of your smoke detectors or if you
have any questions, please contact Gentex Corporation or your local Gentex distributor
If the smoke detector does not work properly, do not try and fix
it yourself. This will void your warranty. See "To Return a Smoke Detector" for
instructions to return smoke detectors that do not operate properly. DO NOT TRY
TO FIX IT YOURSELF.
IMPORTANT: Gentex recommends smoke detectors be tested a minimum of once a
week.
Never use an open flame of any kind to test your smoke
detector. You may ignite and damage the smoke detector as well as the
surrounding area. The test feature of your smoke detector accurately simulates
smoke conditions and tests the smoke detector's functions as required by
ANSI/UL 268.
Do not cover, tape, or otherwise block the openings of your
smoke alarm. These openings are designed to allow air to pass through your
smoke detector, thus sampling the air around the smoke detector.
Smoke detectors are not to be used with detector guards
unless the combination has been evaluated and found suitable for that purpose.
NOTICE: FAILURE TO REGULARLY CLEAN THIS SMOKE DETECTOR MAY RESULT
IN NUISANCE ALARMS. A BUILD UP OF DUST CREATES AN OBSCURATION THAT
\SIMULATES SMOKE. THIS MEANS THE UNIT MAY GO INTO ALARM WITHOUT A
SMOKE CONDITION.
TO RETURN A SMOKE DETECTOR
Should you experience problems with your smoke detector, proceed as follows:
1. Turn off electrical power to the detector.
2. Rotate the detector counter-clockwise to remove it from its mounting plate.
3. Unplug the connector from the back of the detector. Do not remove the wire
connection; leave the connector for your replacement detector. If the system is to
remain active while the detector is removed, a jumper plug must be installed.
