HOW YOUR SMOKE DETECTOR WORKS

The 8000 Series smoke detector operates on the photoelectric light scatter principle.
The unit’s sensing chamber houses a light source and a light sensor.
The darkened sensing chamber is exposed to the atmosphere and designed to permit optimum smoke entry from any direction while rejecting light from outside the detector.
The light source is an infrared (invisible) LED which pulses every 4 to 8 seconds.
The light sensor is a photodiode matched to the light frequency of the LED light source.

Under normal conditions, the light generated by the pulsing infrared LED is not seen by the light sensor. When smoke enters the sensing chamber, light from the pulsing LED light source is reflected by the smoke particles onto the photodiode light sensor. At the first sighting of smoke, the smoke detector is put into a pre-alarm mode. This is indicated by a rapidly flashing LED on the face of the smoke detector.
Once the light sensor confirms smoke for 2 consecutive pulses inside the chamber, the light sensor produces the signal necessary to trigger the alarm.
This technique of verifying the smoke condition, combined with a 5-to-1 signal-to noise ratio, substantially reduces the possibility of nuisance alarms.

PLACEMENT OF SMOKE DETECTORS

THIS EQUIPMENT SHOULD BE INSTALLED IN ACCORDANCE WITH THE NATIONAL FIRE PROTECTION ASSOCIATION’S STANDARD 72 (National Fire Protection Association, Battery march Park, Quincy, MA 02269).

For your, information, the National Fire Protection Association’s Standard 72, 2010 Edition, Chapter 17 states the following:

INSTALLATION OF 8000 SERIES

MOUNT ROUGH-IN BOX & RUN WIRING
IMPORTANT: INSURE THAT ALL FLUORESCENT LIGHTING FIXTURES ARE PROPERLY GROUNDED.

1. Use a 2″ x 3″ switch box or a 4″ square or octagon junction box. Mount a box for each smoke detector and run the system fire detection circuit plus the power circuit to all smoke detector locations. See Wiring Diagrams, FIGURES A and B, for Latching Models, and FIGURES C and D for Self Clearing Models.
   NOTICE: THE WIRING TO BE USED SHALL BE IN ACCORDANCE WITH THE PROVISIONS OF ARTICLE 300.3(B) OF THE NATIONAL ELECTRICAL CODE, NFPA 70, AS WELL AS ARTICLE 210.
   CAUTION: Break wire runs to provide supervision for connections made to each wire pair.

2. If wall mounting is desired, be sure the box screws are oriented to upper right and lower left corners, FIGURE F. The volume of the box is determined by the number of conductors entering and exiting the box. Use 1-3/4 cubic inches per conductor (#16 AWG).
   

INSTALL MOUNTING PLATE & CONNECT WIRES

1. Remove the plug and wire assembly from the shipping container and wire it in junction box as follows:
2. Major Circuits (power in, power out, and alarm contacts) have two wires, one for the incoming circuit and one for the outgoing circuit. Auxiliary relay contacts are single wire circuits. Make connections as detailed on wiring diagrams, FIGURE G.
3. Lace the connector through the provided mounting plate and secure the plate to the junction box.
   NOTICE: FOR TROUBLE AREAS WHERE THERE CAN BE A LARGE VOLUME OF AIR BLOWING OUT THROUGH THE ELECTRICAL JUNCTION BOX. YOU MUST FIRST INSERT THE CARDBOARD SHIELD PACKAGED WITH YOUR SMOKE DETECTOR TO THE BACKSIDE OF THE SMOKE DETECTOR BEFORE SECURING IT TO MOUNTING PLATE.
   

SECURE SMOKE DETECTOR TO MOUNTING PLATE

1. Plug the wire connector into the detector base.
2. Place the smoke detector up to the mounting plate, rotating it clockwise until smoke detector firmly snap locks into place. Keep the smoke detector parallel to the mounting plate so upper and lower tabs on plate seat correctly into detector, FIGURE H.
   

CHECKOUT & TROUBLESHOOTING

1. Turn test knob on each unit to the NORMAL position and supply power to the system Control Unit.
   a. If the fire alarm sounds, one or more smoke detector connections to the fire detection circuit may be reversed. Check wire color codes and trace.
   b. If the trouble buzzer sounds, the fire detection circuit may be reversed or disconnected at the Control Unit.

2. Testing with the Test Knob.
   a. Rotate the test knob on the front of the unit to TEST 1 position (counterclockwise). See FIGURE I. The alarm should sound in less than 20 seconds.
   b. To reset the system, return the knob to its NORMAL position and use the reset switch on the system Control Panel. Hold in reset for 5 or more seconds.
   c. To test smoke detector for high sensitivity, rotate test knob clockwise to the TEST
   2 position. Alarm should remain silent. Return test knob to normal position. If your smoke detector alarmed during TEST 2, the smoke detector’s sensitivity has become too high and may cause false alarms. This may mean your smoke detector is dirty and should be cleaned as described in the below maintenance procedure.
   d. If your detector still alarms in TEST 2 position following washing and recommended drying time, return it to Gentex Corporation for service. The test knob actually tests the sensitivity of the unit by using the same principle involved as when smoke enters the smoke detector. When you turn the test knob to the TEST 1 position, you are scattering the detector’s LED light to the equivalent of 3.4% actual smoke. TEST 2 position is equivalent to 0.85%.

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, Battery march 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.
   WARNING 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.
   WARNING DO NOT open smoke alarm for cleaning. IF SMOKE ALARM IS OPENED DURING CLEANING, PRODUCT WARRANTY BECOMES VOID.
   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

WARNING 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.

WARNING 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.

WARNING 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.

WARNING 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
