GENERAL DESCRIPTION

Model SK-FIRE-CO is a plug-in type smoke sensor that is a photoelectronic

U.L.

sensing chamber combined with carbon monoxide (CO), thermal and infra-red

(IR) sensors as well as a carbon monoxide detector both with addressable-an-

alog communications. The sensors transmit an analog representation of smoke

and/or carbon monoxide density over a communication line to a control panel.

EXTERNAL

SUPPLY24V

Rotary-decade switches are provided for setting the sensor’s address.

Two LEDs on the sensor are controlled by the panel to indicate sensor status.

B.Smoke Entry:

For SK-FIRE-CO, smoke entry testing should be performed immediately following 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 generator 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. Using the bowl shaped applicator, apply aerosol until the panel alarms.

Canned Aerosol Simulated Smoke. Additionally, canned aerosol simulated smoke (canned smoke agent) may be used for smoke entry testing of the smoke detector. Tested and approved aerosol smoke products are:

MANUFACTURER	MODEL

Home Safeguard Industries	25S

SDi	CHEK02 and CHEK06

SDi	SOLOA4

SDi	SMOKESABRE-01

When used properly, the canned smoke agent will cause the smoke detector to go into alarm. Refer to the manufacturer’s published instructions for proper use of the canned smoke agent.

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 entry 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 monoxide 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

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. Direct 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 testers model C6 CO Detector Tester available from SDi. Initiate the CO testing feature of the detector as follows:

•To be seen as a substitute for the proper servicing of fuel-burning appliances or the sweeping of chimneys.

•To be used on an intermittent basis, or as a portable alarm for the spillage 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:

Concentration (ppm CO)	Symptoms

200	Mild headache after 2-3 hours
	of exposure

400	Headache and nausea after
	1-2 hours of exposure

800	headache, nausea, and dizziness
	after 45 minutes of exposure;
	collapse and unconsciousness after
	2 hours of exposure

Many causes of reported carbon monoxide poisoning indicate that while victims are aware that they are not well, they become so disoriented that they are unable to save themselves by either exiting the building or calling for assistance. Also, young children and pets may be the first to be affected.
