ESL Wireless Smoke Alarms C Caddx: NX491T ITI: 60-848-01-95 UL ¤ US LISTED 4300 Series NX Series Wireless Smoke Detector Wireless Smoke Alarm/Detector Wireless Installation Instructions Temperature sensor Sounder LED Test/Silence button Figure 1. Alarm Features Description Selecting a Location The ESL smoke alarms are Learn Mode wireless sensors with 319.5 MHz transmitters that use photoelectric technology with a self contained sounder, a low battery annunciator, and a status LED. The smoke alarms are part of a security/fire alarm system and communicate with the system control panel. Selecting a suitable location is critical to the operation of smoke alarms. This equipment should be installed in accordance with the National Fire Protection Association’s (NFPA) Standard 72. See Figure 2. The smoke alarms provide the following features: Self-diagnostics. The smoke alarms monitor their own sensitivity and operational status. Base tamper switch sends a tamper signal transmission to the control panel when the smoke alarms are removed from their mounting bases. Integrated fixed 135°F temperature and rate of rise heat detector trips an alarm based on high temperature detected or rapidly rising temperature rate (15°F/minute minimum). Transmitted Signal Outputs The smoke alarms transmit the following signals to the control panel: • • • • • • Alarm Tamper Test Low battery Trouble Supervisory ESL Wireless Smoke Alarms A-8-1.2.1.a Where to Locate the Required Smoke Alarms in Existing Construction. The major threat from fire in a family living unit occurs at night when everyone is asleep. The principal threat to persons in sleeping areas comes from fires in the remainder of the unit. Therefore, a smoke alarm(s) is best located between the bedroom areas and the rest of the unit. In units with only one bedroom area on one floor, the smoke alarm(s) should be located as shown in Figure 2 A. In family living units with more than one bedroom area or with more than one floor, more than one smoke alarm is required, as shown in Figure 2 B. In addition to smoke alarms outside of the sleeping areas, the installation of a smoke alarm on each additional story of the family living unit, including the basement, is required. These installations are shown in Figure 2 C. The living area smoke alarm should be installed in the living room or near the stairway to the upper level, or in both locations. The basement smoke alarm should be installed in close proximity to the stairway leading to the floor above. Where installed on an open-joisted ceiling, the alarm should be placed on the bottom of the joists. The alarm should be positioned relative to the stairway to intercept smoke coming from a fire in the basement before the smoke enters the stairway. 1 Dining Room Kitchen Bedroom Living Room Bedroom Bedroom Figure 2 A. Alarm Placement TV Room Dining Room Kitchen Living Room A-8-1.2.1.c Are More Smoke Alarms Desirable? The required number of smoke alarms might not provide reliable early warning protection for those areas separated by a door from the areas protected by the required smoke alarms. For this reason, it is recommended that the householder consider the use of additional smoke alarms for those areas for increased protection. The additional areas include the basement, bedrooms, dining room, furnace room, utility room, and hallways not protected by the required smoke alarms. The installation of smoke alarms in kitchens, attics (finished or unfinished), or garages is not normally recommended, as these locations occasionally experience conditions that can result in improper operation. Bedroom Important ! Bedroom Regulations pertaining to smoke alarm installations vary from state to state. For more information, contact your local fire department or local authority having jurisdiction. Bedroom Figure 2 B. Alarm Placement Bedroom Living Room Bedroom Dining Room Basement Figure 2 C. Alarm Placement In addition to NFPA 72, use the following location guidelines to optimize performance and reduce the chance of false alarms: • Locate ceiling-mounted smoke alarms in the center of a room or hallway at least 4 inches (10.2cm) from any walls or partitions. • Locate wall-mounted smoke alarms so the top of the alarm is 4 to 12 inches (10.2 to 30.5cm) below the ceiling. • Locate in a suitable environment as follows: - Temperature between 40°F (4.4°C) and 100°F (37.8°C) - Humidity between 0 and 95% non-condensing • Locate away from air conditioners, heating registers and any other ventilation source that may interfere with smoke entering the alarm. • Mount smoke alarms on a firm permanent surface, typically a stud or metal runner. • Locate away from large metallic objects. = Required smoke alarms = Additional smoke alarms required for new construction A-8-1.2.1.b Where to Locate the Required Smoke Alarms in New Construction. All of the smoke alarms specified in A-8-1.2.1.a for existing construction are required and, in addition, a smoke alarm is required in each bedroom. 2 ESL Wireless Smoke Alarms Installing the Alarms 1. Slide the battery compartment cover away from the alarm to unsnap it and lift it off. See Figure 3. 2. Observing proper polarity, insert the two lithium batteries provided into the alarm battery compartment and replace the battery compartment cover. 3. Making sure that the unit is removed from its base, put the panel in program mode/Learn Mode. 4. Remove the red plastic dust cover from the alarm. The alarms are shipped with a dust cover for protection on construction sites with dusty environments. 5. With the base still removed, press the test/silence button until the panel indicates that the sensor has been enrolled. 6. Before permanently mounting the alarm, disconnect the alarm notification appliances and test the communication between the control panel and each smoke alarm as follows: - Press the test/silence button on the alarm for 2 seconds. The alarm sends a test signal to the control panel. - At the control panel, verify the test signal was received and the RF signal strength is adequate. If no signal is received or the RF signal is weak, relocate the alarm and retest. 7. Using the two screws and anchors provided, mount the base. 8. Attach the alarm to the mounting base as follows: - Line up the raised tab on the lip of the alarm with the slot on the lip of the mounting base. See Figure 3. - Insert the alarm into the base and turn clockwise approximately 15 degrees. It should snap firmly into place. 9. Test the communication between the control panel and each smoke alarm as follows: - One at a time, press the test/silence button on the alarm for 2 seconds. The alarm sends a test signal to the control panel. Tab Slot Battery compartment Figure 3 - Alarm-to-Base Alignment Smoke Testing the Alarms Smoke alarms should be tested in place annually using smoke or Smoke! in a can®. Follow the instructions on the canned smoke or use the following steps to test the alarms with smoke: 1. Hold a smoldering punk or cotton wick close to the smoke entry openings. 2. Gently direct the smoke into the unit for 20 seconds or until an alarm is indicated. Be sure to properly extinguish the smoke source after testing! The alarm LED should remain on while the built-in transmitter sends an alarm signal to the control panel. The alarms will sound a temporal rhythm until the test/silence button is pressed. The alarms automatically reset when smoke is no longer present. Note Continuing to press and hold the test button for more than 20 seconds will send an alarm signal to a control station. - At the control panel, verify the test signal was received. 10. Test each alarm (see Smoke Testing the Alarm) and reconnect all alarm notification appliances. Important ! The control panel alarm and all auxiliary functions should be verified for a complete test of the system. ESL Wireless Smoke Alarms 3 Testing the Alarms Sensitivity The smoke alarms provide a sensitivity level test mode that allows you to check the alarm sensitivity using the test/silence button and the LED indicator on the alarms as follows: 1. Press the test/silence button on the alarm for 2 seconds. First the alarm transmits a test signal to the panel, and then performs a test and the LED flashes one to nine times. 2. Count the number of LED flashes and use the following table to determine the status of the alarm sensitivity and what action to take, if any. Flashes Obscuration (Approx) Indication Action 1 N/A Unser viceable hardware fault detected. Reset unit by removing batteries and rerun sensitivity test. If the error persists, replace the unit. 2-3 N/A Alarm is not sensitive enough. Clean the unit. Reset unit by removing batteries and rerun sensitivity test. If the error persists, replace the unit. Alarm is within normal sensitivity range. N/A Alarm is too sensitive. Verify that the smoke chamber is snapped down securely. Clean the unit.Replace chamber par t #211. 4 3.1%/ft 5 2.6%/ft 6 2.1%/ft 7 1.6%/ft 8-9 N/A Understanding the Test/Silence Button The test/silence button performs four functions as follows: 1. Sounder/Sensitivity Test - Press the test/silence button until the LED lights or the sounder activates (about 2 seconds) and release. The alarm performs a sounder test and a sensitivity test and sends a test signal to the control panel. This allows users to test the unit on compatible panels without putting the panel in test mode and therefore reduces false alarms. 2. Central Station Alarm Test - To force an alarm report to the central station, press the test/silence button down and hold it for two complete temporal cycles (about 9 seconds). 3. Silence Alarm - Press and release to silence the sounder during an alarm. After a few minutes, the sounder and alarm will resume if smoke is still present. 4. Silence Low Battery Chirp - Press and release to silence a low battery chirp. The low battery chirp resumes after 24 hours if the condition is not corrected. Understanding the LED The LED indicates the status of the alarms as follows: If the sensitivity is not within limits, or an unserviceable hardware fault is detected, the LED extinguishes until the alarm is serviced and the built-in transmitter sends a trouble signal to the control panel if the alarm is too sensitive or stops sending a supervisory signal if the alarm is not sensitive enough. FLASHING = Flashes every 9 seconds to indicate normal operation. ON = Detects smoke, sending an alarm. OFF = Trouble. Maintenance is required. Check the control panel to determine what action to take. If the alarm has a hardware fault, it will stop reporting supervision signals to the panel. Attaching and Removing the Alarms To remove the alarm from the mounting base, grasp the alarm and turn counterclockwise approximately 15 degrees. The alarm should snap off of the mounting base. Attach the smoke alarm to the mounting base as follows: - Line up the raised tab on the lip of the smoke alarm with the slot on the lip of the mounting base. See Figure 3. - Insert the smoke alarm into the base and turn clockwise approximately 15 degrees. It should snap firmly into place. When to Replace the Batteries Figure 4. Removing Alarm Cap 4 When the batteries are low, the alarm sends a low battery signal to the control panel, waits several days and then chirps every 30 seconds until the batteries are replaced. The sounder can be silenced for 24 hours by pushing the test/silence button. See Specifications for battery type list. ESL Wireless Smoke Alarms Replacing the Batteries Maintaining the Alarms Use only 3V lithium batteries listed in Specifications in the alarm.

ESL Wireless Smoke Alarms 5 Fire Prevention and Escape The purpose of an early warning smoke alarm is to detect the presence of fire in its early stages and sound an alarm giving the occupants time to exit the premises safely. • If you have children and/or physically challenged people residing in your household, use window decals to help emergency personnel identify the sleeping quarters of these individuals. Avoid Fire Hazards No detection device can protect life in all situations. Therefore, safeguards should be taken to avoid potentially dangerous situations as follows: • • • • Do not smoke in bed. Do not leave children home alone. Never clean with flammable liquids such as gasoline. Properly store materials. Use general good housekeeping techniques to keep your home neat and tidy. A cluttered basement, attic, or other storage area is an open invitation to fire. • Use combustible materials and electrical appliances carefully and only for their intended uses. Do not overload electrical outlets • Do not store explosive and/or fast burning materials in your home. • Even after proper precautions have been taken, fires can start. Be prepared. In Case of Fire In the event of a fire, you should do the following: • Leave immediately. Don’t stop to pack or search for valuables. • In heavy smoke, hold your breath and stay low, crawl if necessary. The clearest air is usually near the floor. • If you have to go through a closed door, carefully feel the door and door knob to see if undue heat is present. If they seem cool, brace your foot against the bottom of the door with your hip against the door and one hand against the top edge. Open it slightly. If a rush of hot air is felt, slam the door quickly and latch it. Unvented fire tends to build up considerable pressure. Be sure all members of the household realize and understand this danger. • Use your neighbor’s phone or a street fire alarm box to call the fire department. The job of extinguishing the fire should be left to the professionals. Be Prepared Practice the following steps to prepare you and your family in the event of a fire: • Perform fire drills regularly. Use them to assure recognition of an alarm signal. • Draw a floor plan and show two exits from each room. It is important that children be instructed carefully, because they tend to hide in times of crisis. • Establish one meeting place outside the home. Insist that everyone meet there during an alarm. This will eliminate the tragedy of someone reentering the house for a missing member who is actually safe. 6 WARNING Smoke alarms CANNOT provide warnings for fires resulting from explosions, smoking in bed or other furniture, ignition of flammable liquids, vapors and gases, children playing with matches or lighters. Warning! Limitations of Smoke Alarms Wireless smoke alarms are very reliable, but may not work under all conditions. No fire alarm provides total protection of life or property. Smoke alarms are not a substitute for life insurance. Smoke alarms require a source of power to work. This smoke alarm will not operate and the alarm will not sound if batteries are dead or not installed properly. Unreliable transmission or receiving of radio frequency (RF) signals may occur if the system is not installed, located, serviced and repaired properly. RF signals sent by this alarm may be blocked or reflected by metal objects. Adjacent devices or systems using radio frequency signals may interfere with the operation of this alarm. Test the system often to be sure that signals are being sent and received properly. Smoke alarms may not be heard. A sound sleeper or someone who has taken drugs or alcohol may not awaken if the alarm is installed outside a bedroom. Closed or partially closed doors and distance can block sound. This alarm is not designed for the hearing impaired. Smoke alarms may not always activate and provide warning early enough. Smoke alarms only activate when enough smoke reaches the detector. If a fire starts in a chimney, wall, roof, on the other side of closed doors, or on a different level of the property enough smoke may not reach the detector for it to alarm. Smoke alarms are a significant help in reducing loss, injury and even death. However, no matter how good a detection device is, nothing works perfectly under every circumstance and we must warn you that you cannot expect a smoke alarm to ensure that you will never suffer any damage or injury.
