B. Smoke Entry:
For SD355CO, smoke entry testing should be performed immediately fol-
lowing the magnet test. Magnet test initiates an approximately 10 minute
period when the detector’s signal processing software routines are not
active. Failure to first perform the magnet test will introduce a time delay
before the detector alarms.
Aerosol Generator (Gemini 501)
The GEMINI model 501 aerosol genera-
tor can be used for smoke entry testing. Set the generator to represent
4%/ft to 5%/ft obscuration as described in the GEMINI 501 manual. Us-
ing the bowl shaped applicator, apply aerosol until the panel alarms.
Canned Aerosol Simulated Smoke.
Additionally, canned aerosol simu-
lated smoke (canned smoke agent) may be used for smoke entry testing
of the smoke detector. Tested and approved aerosol smoke products are:
When used properly, the canned smoke agent will cause the smoke de-
tector to go into alarm. Refer to the manufacturer’s published instruc-
tions for proper use of the canned smoke agent.
CAUTION
Canned aerosol simulated smoke (canned smoke agent) formulas will vary by
manufacturer. Misuse or overuse of these products may have long term adverse
effects on the smoke detector. Consult the canned smoke agent manufacturer’s
published instructions for any further warnings or caution statements.
C. Direct Heat Method (Hair Dryer of 1000-1500 watts)
A hair dryer of 1000-1500 watts should be used to test the thermistors. Di-
rect the heat toward either of the two thermistors, holding the heat source
approximately 12 inches from the detector in order to avoid damaging
the plastic housing. The detector will reset only after it has had sufficient
time to cool. Make sure both thermistors are tested individually.
D. Multi-Criteria Testing
Testifire® by SDi provides testing of the smoke, heat and CO sensors. Consult
the manufacturer’s published instructions for complete usage instructions.
A sensor that fails any of these tests should be cleaned as described under
CLEANING, and retested. If the sensor fails after cleaning, it must be replaced.
When testing is complete, restore the system to normal operation and notify
the proper authorities that the system is back in operation.
FUNCTIONAL GAS TEST
NOTE: Check with local codes and the AHJ to determine whether or not a
functional gas test is desired for an installation.
A canned CO testing agent may be used to verify the detector’s ability to
sense CO. Tested and approved canned CO testing agent is solo detector tes-
ters model C6 CO Detector Tester available from SDi. Initiate the CO testing
feature of the detector as follows:
1. Put the device into test mode by holding a test magnet in the magnet test
area as shown in Figure 3 for 6-12 seconds.
NOTE: If the magnet is held in place for too long the fire alarm test function
will be triggered. Reset the panel and proceed with testing the CO portion of
the device. It may be preferred to put the device into fire alarm first via the
magnet test to ensure the device has successfully entered test mode.
2. Spray a UL approved CO agent into the top ring of the detector’s gas en-
try ports within 1/4” of the detector for at least 1 second (see Figure 4). It
is recommended to use the applicator straw included with the CO agent
to more efficiently direct the CO into the detection cell during testing.
3. The detector will go into alarm if gas entry is successful. It may take up
to 1 minute for the device to alarm. Once the detector is in alarm allow 5
minutes for the CO to clear and exit the detector.
The dector will automatically enable the signal processing after 10 minutes.
Testing the detector will activate the alarm relay and send a signal to the panel.
CAUTION: This carbon monoxide detector is designed for indoor use only.
Do not expose to rain or moisture. Do not knock or drop the detector. The
detector will not protect against the risk of carbon monoxide poisoning if not
properly wired. The detector will only indicate the presence of carbon mon-
oxide gas at the sensor. Carbon monoxide gas may be present in other areas.
This carbon monoxide detector is NOT:
• Designed to detect any gas other than carbon monoxide
• To be seen as a substitute for the proper servicing of fuel-burning appli-
ances or the sweeping of chimneys.
• To be used on an intermittent basis, or as a portable alarm for the spill-
age of combustion products from fuel-burning appliances or chimneys.
Carbon monoxide gas is a highly poisonous gas which is released when fuels
are burnt. It is invisible, has no smell and is therefore impossible to detect with
the human senses. Under normal conditions in a room where fuel burning
appliances are well maintained and correctly ventilated, the amount of carbon
monoxide released into the room by appliances should not be dangerous.
Symptoms of carbon monoxide poisoning:
Carbon monoxide bonds to the
hemoglobin in the blood and reduces the amount of oxygen being circulated
in the body. The following symptoms are examples taken from NFPA 720.
They represent approximate values for healthy adults:
