This sensor must be installed in compliance with the control panel sys-tem installation manual. For local audible indication of a fire and/or carbon monoxide alarm, it is recommended to install the multi-criteria carbon monoxide (CO) and smoke sensors into a APB200 series sounder base. If a local audible device is not used, care should be taken to de-velop a proper response plan. The installation must meet the require-ments of the Authority Having Jurisdiction (AHJ). Sensors offer maximum performance when installed in compliance with the National Fire Protec-tion Association (NFPA); see NFPA 72 and NFPA 720. For a complete list of compatible bases, refer to the Base/Sensor Cross Reference Chart at systemsensor.com.

GENERAL DESCRIPTION

MIX-FC351AP is a plug-in type multi-criteria smoke sensor that offers a pho- toelectric sensing chamber combined with a carbon monoxide (CO) sensor, 135°F (57.2°C) fixed temperature heat detector and infrared (IR) sensors, as well as a carbon monoxide dtector. The MIX-FC351AP also transmits an alarm signal due to heat (135°F/57.2°C) per UL 521.
All sensors transmit an analog representation of smoke and/or carbon monox-ide density over a communication line to a control panel. Rotary dial switches are provided for setting the sensor’s address. (See Figure 2.)
Two LEDs on the sensor are controlled by the panel to indicate sensor status. An output is provided for connection to an optional remote LED annunciator (P/N RA100Z).
Mircom panels offer different features sets across different models. As a result, certain features of the photoelectric sensors may be available on some control panels, but not on others.
The multi-criteria CO and smoke sensor supports Advanced Protocol mode. The possible features available in the multi-criteria CO and smoke sensors, if supported by the control unit are:

1. The sensor’s LEDs can operate in three ways—on, off, and blinking—and they can be set to red, green, or amber. This is controlled by the panel.
2. The remote output may be synchronized to the LED operation or con-trolled independent of the LEDs.
3. Devices are point addressable up to 159 addresses.

Please refer to the operation manual for the UL listed control panel for spe- cific operation. The multi-criteria CO and smoke sensors require compatible addressable communications to function properly. Connect these sensors to listed-compatible control panels only.

SPACING

Mircom recommends spacing smoke detectors in compliance with NFPA 72. In low air flow applications with smooth ceilings, space sensors 30 feet apart (9.1 m). For specific information regarding sensor spacing, placement, and special applications, refer to NFPA 72 and the System Smoke Detector Ap-plication Guide, available from Mircom. For specific information regarding CO detector spacing, placement and special applications, refer to NFPA 72, NFPA 720, and the System-Connected Carbon Monoxide Detectors Application Guide also available from Mircom.

WIRING GUIDE

All wiring must be installed in compliance with the National Electrical Code, applicable local codes, and any special requirements of the Authority Having Jurisdiction. Proper wire gauges should be used. The installation wires should be color-coded to limit wiring mistakes and ease system troubleshooting. Improper connections will prevent a system from responding properly in the event of a fire.
Remove power from the communication line before installing sensors.

1. Wire the sensor base (supplied separately) per the base wiring diagram.(See Figure 1.)
2. Set the desired address on the sensor address switches. (See Figure 2.)
3. Install the sensor into the sensor base. Push the sensor into the base while turning it clockwise to secure it in place.
4. After all sensors have been installed, apply power to the control panel and activate the communication line.
5. Test the sensor(s) as described in the TESTING section of this manual.

CAUTION
Dust covers provide limited protection against airborne dust particles during shipping. Dust covers must be removed before the sensors can sense smoke. Remove sensors prior to heavy remodeling or construction.

TAMPER RESISTANCE

Model MIX-FC351AP includes a tamper-resistant capability that prevents re- moval from the base without the use of a tool. Refer to the base manual for details on making use of this capability.

TESTING

Before testing, notify the proper authorities that the system is undergoing maintenance, and will temporarily be out of service. Disable the system to prevent unwanted alarms.
All sensors must be tested after installation and periodically thereafter. Test-ing methods must satisfy the Authority Having Jurisdiction (AHJ). Sensors offer maximum performance when tested and maintained in compliance with NFPA 72. Sensitivity readings are available through the FACP. Refer to the manufac turer’s published instructions for proper use.
The sensor can be tested in the following ways:

• A. Functional: Magnet Test (P/N M02-04-01 or M02-09-00)
  This sensor can be functionally tested with a test magnet. The test magnet electronically simulates smoke in the sensing chamber, testing the sensor electronics and connections to the control panel.

  • a. Hold the test magnet in the magnet test area as shown in Figure 3.
  • b. The sensor should alarm the panel.
    Two LEDs on the sensor are controlled by the panel to indicate sensor status. Coded signals, transmitted from the panel, can cause the LEDs to blink, latch on, or latch off. Refer to the control panel technical documen-tation for sensor LED status operation and expected delay to alarm.
    NOTE: The magnet test initiates an approximately 10 minute period when the detector’s signal processing software routines are not active.

• B. Smoke Entry
  Canned aerosol simulated smoke (canned smoke agent) may be used for smoke entry testing of the smoke detector.
  The multi-criteria CO and smoke sensor uses algorithms to process sig-nals received from multiple sensors to determine alarm conditions and reduce false alarms. Therefore, a single burst of canned smoke will not immediately place the detector into an alarm condition because the detec-tor algorithms correctly determine a burst of canned smoke is not fire. In order to perform functional testing of the photoelectric sensor, the device must be placed into test mode. Test mode allows the detector to isolate the individual sensors for testing. The device can be placed into test mode through either of the following methods.

  • a. 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 func- tion will be triggered. (See Magnet Test, above.) Reset the panel and pro-ceed with testing the smoke entry portion of the device.

  • b. Perform smoke entry testing immediately following the magnet test. The magnet test initiates an approximately 10 minute period when the detec-tor’s signal processing software routines are not active.
    Once in test mode, test the smoke detector using one of the tested and ap- proved aerosol smoke products. Refer to the manufacturer’s published instruc- tions for proper use of the canned smoke agent. When used properly, the canned smoke agent will cause the smoke detector to go into alarm.
    Tested and approved aerosol smoke products include:

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 manu-facturer’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 the thermistor, holding the heat source approximately 12 inches (30 cm) 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 may need to be cleaned as described under CLEANING, and retested. When testing is complete, restore the system to normal operation and notify the proper authorities that the system is back in operation.

• E. 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. Carbon Monoxide alarm thresholds are designed around CO concentrations over time, as defined in UL standard 2034. Therefore, a single burst of CO test agent will not immediately place the detector into an alarm condition. In order to perform functional testing of the CO sen-sor, the device must be placed into test mode. Test mode eliminates the time and concentration requirements needed for alarm and allows the CO sensor to be tested. The device can be placed into test mode through either of the following methods.

  • a. 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 func- tion will be triggered. Reset the panel and proceed with testing the CO portion of the device.

  • b. Perform functional gas entry testing immediately following the magnet test. The magnet test initiates an approximately 10 minute period when the detector’s signal processing software routines are not active.

  • Once in test mode, test the CO sensor using a tested and approved canned CO testing agent. A tested and approved canned CO testing agent is Solo detector testers model C6 CO Detector Tester available from SDi. Complete the CO sensor testing as follows:

  • Spray a UL approved CO agent into the top of the detector near the CO sensor opening for at least 1 second. CO sensor opening is indicated by a triangle on the sensor cover. (See Figure 3.) Use the applicator straw included with the CO agent to more efficiently direct the CO into the detec-tion cell during testing.

  • 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 detector will automatically enable the signal processing after 10 min-utes.

  • Testing the detector will activate the alarm relay and send a signal to the panel.

CLEANING

Before removing the detector, notify the proper authorities that the smoke detector system is undergoing maintenance and will be temporarily out of service. Disable the zone or system undergoing maintenance to prevent un- wanted alarms.

1. Remove the sensor to be cleaned from the system.
2. Remove the sensor cover by pressing firmly on each of the four removal tabs that hold the cover in place. (See Figure 4.)
3. Vacuum the screen carefully without removing it. If further cleaning is required continue with Step 4, otherwise skip to Step 7.
4. Remove the chamber cover/screen assembly by pulling it straight out.
5. Use a vacuum cleaner or compressed air to remove dust and debris from the sensing chamber.
6. Reinstall the chamber cover/screen assembly by aligning the arrows on the top with the two round-top posts on the sensing chamber, and gently pressing it until it fits securely.
7. Replace the cover using the LEDs to align the cover and then gently push-ing it until it locks into place. NOTE: Make sure that the thermistors do not become bent under the cover.
8. Reinstall the detector.
9. Test the detector as described in TESTING.
10. Reconnect disabled circuits.
11. Notify the proper authorities that the system is back on line.

ABOUT CARBON MONOXIDE DETECTORS

CAUTION
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
• 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 burn-ing appliances are well maintained and correctly ventilated, the amount of carbon monoxide released into the room by appliances should not be danger-ous.

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 72 and 720. They represent approximate values for healthy adults:

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 vic-tims 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.
Per UL standard 2075, the MIX-FC351AP have been tested to the sensitivity limits defined in UL standard 2034.

ALARM THRESHOLDS ARE AS FOLLOWS

What to do if the carbon monoxide detector goes into alarm:
Immediately move to a spot where fresh air is available, preferably out-doors.
IMPORTANT: This detector should be tested and maintained regularly fol-lowing National Fire Protection Association (NFPA) 72 and 720 require-ments.

CO SENSOR LIFETIME

The CO cell has an expected lifetime of approximately ten years. The detector is programmed to signal the approach of end of this lifetime to the control panel. The CO cell is not a field replaceable component. The smoke sensor will continue to operate using other sensing elements (photoelectric, heat and infrared) even though the CO cell is no longer operational. The CO detector will not operate once the CO cell has reached its end of life.

SPECIAL NOTE REGARDING SMOKE DETECTOR GUARDS
Smoke detectors are not to be used with detector guards unless the combina- tion has been evaluated and found suitable for that purpose.

SPECIAL APPLICATION

When configured at the fire alarm control panel, this detector is capable of op-erating in a special application mode such that it has a higher sensitivity than is normally allowed by UL 268 for areas where early warning is important. In this mode, the detector does not comply with the Cooking Nuisance Smoke Test. Detectors (Sampling ports) set to the special application mode are not suitable for use in areas where cooking appliances may be used. If cooking appliances are used within the protected space, a normal application detector or normal application mode must be used for that area.
Special application mode is not for general use and the detector may be more prone to false alarms if used in unsuitable environments. While no list is all-inclusive, some examples of unsuitable environments for special applica- tion mode are areas with airborne particulate or aerosols including sawing, drilling, and grinding operations, textile or agricultural processing, or areas with engines that are not vented to the outside. A complete list of aerosol and particulate sources is available in the Annex of NFPA 72.
Suitable environments for special application mode could include early warn- ing for hospitals, museums, assisted living and other areas that do not have airborne particulate or aerosols.
Refer to the fire alarm control panel documentation for information on how to configure the detector for special application mode.
