The 8240P/8100P models produce a non-temporal audible alarm and are
therefore not intended for locations where the desired action of the
occupant(s) is evacuation.
The 8243P/8103P models produce a temporal 3 audible alarm. Per NFPA
72, the American National Standard Audible Emergency Evacuation
Signal as defined in ANSI S3.41, is required whenever the intended
response is to evacuate the building.

HOW YOUR S OKE 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.
Installation Instructions - Owner's Information READ CAREFULLY AND SAVE
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.

For your, information, the National Fire Protection Association’s Standard 72, 2010
Edition, Chapter 17 states the following:
17.7.3.1.1 The location and spacing of smoke detectors shall be based upon the
anticipated smoke flows due to the plume and ceiling jet produced by the anticipated
fire, as well as any pre-existing ambient airflows that could exist in the protected
compartment.
17.7.3.1.2 The design shall account for the contribution of the following factors in
predicting detector response to the anticipated fires to which the system is intended to
respond:
(1) Ceiling shape and surface

2. If wall mounting is desired, be sure the box screws are oriented to upper right and
lower left corners, FI URE 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
AW ).
INSTALL OUNTING 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, FI URE .
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 LAR E VOLUME OF
AIR BLOWIN OUT THROU H THE ELECTRICAL JUNCTION BOX. YOU MUST
FIRST INSERT THE CARDBOARD SHIELD PACKA ED WITH YOUR SMOKE
DETECTOR TO THE BACKSIDE OF THE SMOKE DETECTOR BEFORE SECURIN
IT TO MOUNTIN PLATE.
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 (counter-
clockwise). See FI URE 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 entex 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%.

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.
I PORTANT: 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 DRYIN
TIME. THIS COULD RESULT IN DAMA E 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 entex Corporation or your local entex 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.
I PORTANT: entex 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 RE ULARLY 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 O INTO ALARM WITHOUT A
SMOKE CONDITION.

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, entex 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 FI URE 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.
AINTENANCE
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 CLEANIN INSTRUCTIONS COULD
RESULT IN DAMA E 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 S OKE ALAR IS
OPENED DURING CLEANING, PRODUCT WARRANTY BECO ES VOID.
