ESL 500N Series Smoke Detector Installation Sheet Additional features Depending on the model, the smoke detector may also provide the following features. CleanMe: Enables a CleanMe compatible control panel to receive a warning signal, indicating that the optical chamber needs to be replaced. This feature is available on the 500N Series two-wire detectors only. The 500N Series two-wire detectors enable the CleanMe function by recognizing voltage polarity at installation. If the + and − terminal connections are reversed, the CleanMe function is enabled. New 500N Series detectors are compatible on the same loop with previous 500 Series detectors if proper wiring is observed. See “Wiring” on page 4. Description Integral temporal-three sounder: In the 500N models with sounder, a piezoelectric horn produces an interrupted 85 dBA tone when the detector alarms or when the polarity is reversed. Sounder follows input voltage in reverse polarity. Note: This document is intended for licensed electricians or alarm installers. We cannot provide technical support to unqualified persons. If you have any questions, contact us using the “Contact information” on page 8. In order for all sounders to activate when the panel alarms, the panel must reverse the supply voltage polarity to the loop on alarm. If the panel does not implement polarity reversal, an ESL 405 Polarity Reversal Relay Module must be used. (Refer to the installation sheet for the ESL 405 Polarity Reversal Relay Module.) The ESL 500N Series conventional two-wire and four-wire photoelectric smoke detectors have intelligent software and digitally processed sensing capabilities. This intelligence, coupled with the ESL patented optical sensing chamber, means the ESL 500N Series quickly and accurately detects smoke. CleanMe compatible software, self-diagnostics, and dust (drift) compensation are standard in every unit. The ESL 500N Series offers application flexibility with optional auxiliary relays, rate-of-rise/fixed temperature heat sensors, isolated heat sensors and/or 85 dBA temporal-three sounders. Auxiliary and end-of-line relays: Auxiliary relays are Form C and operate at 1 A at 30 VDC to allow for the addition of auxiliary notification devices to the smoke loops. Products with an “R” in the suffix signify the auxiliary relay feature. An end-of-line relay operates as a power supervision relay and is normally energized and will release with the loss of power. Products with an “E” in the suffix signify the end-of-line feature. Standard features All models ship standard with the features described below. Heat sensors: Some models come with rate-of-rise or fixed temperature heat sensors which allow the unit to detect changes in temperature that may signal a fire event. Models with an “XT” in the suffix have a heat sensor included. Detector-base lock: Discourages unauthorized removal of the smoke detector by requiring a screwdriver to remove the detector from the base. Self-diagnostics: Includes automatic sensitivity testing. Once a day and immediately upon first power up, each 500N Series detector performs a full diagnostic test that includes a dynamic test of the sensing chamber and internal electronics. This meets NFPA 72 field sensitivity testing requirements without the need for external meters. Some models are available with an isolated heat sensor. If the unit senses a temperature change it will alert the panel and signal an alarm independent of smoke in the photoelectric chamber. The heat alarm output is on the alarm relay and the smoke detector output is on the auxiliary relay. Models with an “H” in the suffix have an isolated heat sensor which is both rate of-rise and fixed temperature. Drift compensation (dust compensation): The detectors automatically adjust sensitivity, up to a maximum of 1.0%/ft., as the detectors become dirty. © 2017 United Technologies Corporation 1/8 P/N 1036525-EN • REV F Compatibility Please refer to the ESL Compatibility Index for a complete listing of control panels and proper identifiers. For a copy of the compatibility index, see “Contact information” on page 8. Remember, four-wire smoke detectors do not require a compatibility listing. Selecting a location Where to locate the required smoke detectors in new construction. All of the smoke detectors specified for existing construction are required and, in addition, a smoke detector is required in each bedroom. Selecting a suitable location is critical to the operation of smoke detectors. This equipment should be installed in accordance with NFPA 72. Figure 1 shows required and additional locations. Figure 1: Detector location (1) (2) (4) (4) (3) (5) (1) (2) (3) (4) (4) A smoke detector should be installed in the living room or near the stairway to the upper level, or in both locations. The basement smoke detector 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. (4) (4) B Are more smoke detectors desirable? The required number of smoke detectors might not provide reliable early warning protection for those areas separated by a door from the areas protected by the required smoke detectors. For this reason, it is recommended that the householder consider the use of additional smoke detectors 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 detectors. The installation of smoke detectors in kitchens, attics (finished or unfinished), or garages is not normally recommended, as these locations occasionally experience conditions that can result in improper operation. Note: Regulations pertaining to smoke detector installation vary from state to state. For more information, contact your local fire department or local authority having jurisdiction. C (4) (4) (3) Additional considerations. In addition to NFPA 72, use the following location guidelines to optimize performance and reduce the chance of false alarms from the detector: • Locate ceiling-mounted smoke detectors in the center of a room or hallway at least 4 in. (10 cm) from any walls or partitions. • Locate wall-mounted smoke detectors so the top of the alarm is 4 to 12 in. (10 to 31 cm) below the ceiling. • Do not locate detectors in or near bathrooms or kitchens. • Locate smoke alarms in a suitable environment with temperature and humidity as defined in “Specifications” on page 8. • Locate smoke detectors away from air conditioners, heating registers, and any other ventilation source that may interfere with smoke entering the alarm. • Mount smoke detectors on a firm, permanent surface.

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 detector 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 detector should be located as shown in Figure 1-A. In family living units with more than one bedroom area or with more than one floor, more than one smoke detector is required, as shown in Figure 1-B. In addition to smoke detectors outside of the sleeping areas, the installation of a smoke detector on each additional story of the family living unit, including the basement, is required. These installations are shown in Figure 1-C. The living area 2/8 Installing the detector All wiring must conform to the National Electric Code (NEC) and/or local codes having jurisdiction. Use 12 to 24 AWG (16 to 22 AWG recommended) wire to install the detector. 1. If you are using the detector-base lock, remove the detector knockout and break off the tab on the mounting base. See Figure 2. 2. Remove the red plastic cover from the detector. The detector is shipped with a cover for protection against construction site dust. P/N 1036525-EN • REV F 3. Run system wiring to the detector location and mount electrical boxes if necessary. The detector fits standard single-gang boxes and 3-1/2 in. and 4 in. round ceiling boxes. 4. Line up and attach the mounting base to the electrical box, wall, or ceiling using the screws provided. Use wall anchors if necessary. See Figure 3. 5. Strip the system wires and connect them to the appropriate terminals on the detector. See “Wiring” on page 4. 6. Attach the detector to the mounting base as follows: Figure 4: Mounting a. Line up the raised tab on the side of the detector with the arrow on the mounting base. See Figure 4. b. Insert the smoke detector into the base and turn clockwise approximately 15 degrees. It should snap firmly into place. 7. Removing the detector To remove the detector from the mounting base: Grasp the detector and turn it counterclockwise approximately 15 degrees. The detector should snap off of the mounting base. Apply power and test the detector. See “Smoke testing” on page 5. Figure 2: Detector-base lock To remove the detector from the mounting base when the detector-base lock is used: Insert a small screwdriver into the locking tab slot on the side of the base and press in while simultaneously turning the detector counterclockwise 15 degrees.

Test the detector. See “Sensitivity testing” below. Smoke testing Smoke detectors should be tested in place annually using one of the following methods: Cleaning the detector • Use Smoke! In A Can (P/N SM-200), a canned aerosol simulated smoke, and follow the directions on the can. Clean the detector cover with a dry or damp (water) cloth as needed to keep it free from dust and dirt. • Hold a smoldering punk or cotton wick close to the unit and gently direct the smoke into the detector for 20 seconds or until an alarm is indicated. When necessary, clean the detector interior and replace the optical chamber as follows: 1. Disconnect the alarm notification appliances, service release devices, and extinguishing systems. 2. Slide a flat-blade screwdriver into the slot on the detector cap and gently push the handle down to pry the cap up and off. See Figure 10. 3. Press in on the sides of the optical chamber and pull it up and away from the detector and discard. See Figure 11. 4. Use a vacuum to remove dust and dirt from the optical chamber base. 5. Line the new optical chamber up with the optical chamber base and snap it down into place. 6. Replace the detector cap as follows: Be sure to extinguish the smoke source after testing! The detector LED should stay on and an alarm should be indicated at the control panel. Use the system reset switch to reset the detector. Sensitivity testing The detector provides a sensitivity test that allows you to check the detector sensitivity using a test magnet and the LED indicator on the detector as follows: 1. 2. Hold the test magnet up to the raised TEST letters on the top of the detector for 2 seconds. See Figure 9. Once the test starts, the alarm LED flashes one to nine times. a. Line the tabs on the cap with the slots on the detector. Count the number of times the LED flashes and use the following table to determine the status of the detector sensitivity and what action to take, if any. b. Insert the cap into the smoke detector and turn clockwise approximately 15 degrees. It should snap firmly into place. Flashes Indication Action 7. 0 to 1 Unserviceable hardware fault Reset and rerun the sensitivity test. If the error persists, replace the unit. Test the detector sensitivity (See “Sensitivity testing” above). 8. Unit is becoming insensitive Clean and reset the unit. Rerun the sensitivity test. If the error persists, replace the unit. Reconnect all alarm notification appliances, service release devices and extinguishing systems. 2 to 3 4 to 7 Unit is within normal N/A sensitivity range 8 to 9 Unit is becoming too sensitive Note: The control panel alarm and all auxiliary functions should be verified for a complete test of the system. Figure 10: Removing the detector cap Verify that the optical chamber is snapped down securely. Clean the unit. After the test: • If the sensitivity is within limits and all other tests pass, the detector goes into alarm and must be reset from the control panel. • If the sensitivity is not within limits or an unserviceable hardware fault has been detected, the detector LED flashes every 1.5 seconds until the detector is serviced. P/N 1036525-EN • REV F 5/8 Figure 11: Removing the optical chamber In case of fire In the event of a fire, 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 doorknob 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 you feel a rush of hot air, 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. (1) (2) (3) (1) (2) (3) Optical chamber base Optical chamber Detector cap Be prepared Practice the following steps to prepare you and your family in the event of a fire: Maintenance • These smoke detectors are designed for easy field service and maintenance. When installed and used properly, they require minimal maintenance. 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. • If you have children or physically challenged people residing in your household, use window decals to help emergency personnel identify the sleeping quarters of these individuals. The smoke detector should be tested monthly. See “Sensitivity testing” and “Smoke testing” on page 5. Fire prevention and escape The purpose of an early warning smoke detector is to detect the presence of fire in its early stages and sound an alarm giving the occupants time to exit the premises safely. 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 invites 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. • 6/8 Even after proper precautions have been taken, fires can start. Be prepared. Limitations of smoke detectors WARNING: Risk of personal injury or death. Smoke detectors cannot provide warnings for fires resulting from explosions, smoking in bed or other furniture, ignition of flammable liquids, vapors, and gases, or children playing with matches or lighters. Failure to properly install, test, and maintain a smoke detector system may cause it to fail resulting in loss of life or property. Smoke detectors are very reliable, but may not work under all conditions. No fire alarm provides total protection of life or property. Smoke detectors are not a substitute for life insurance. Smoke detectors require a source of power to work. This smoke detector will not operate and the alarm will not sound if the detector is not installed properly. Smoke detectors may not be heard. A sound sleeper or someone who has taken drugs or alcohol may not awaken if the detector is installed outside a bedroom. Closed or partially closed doors and distance can block sound. This detector is not designed for the hearing impaired. P/N 1036525-EN • REV F Smoke detectors may not always activate and provide warning early enough. Smoke detectors 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. Model numbers Figure 12: Model number codes Features Style Smoke detectors 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 detector to ensure that you will never suffer any damage or injury. Wiring Features Current studies have shown smoke detectors may not awaken all sleeping individuals. It is the responsibility of individuals in the household that are capable of assisting others to provide assistance to those who may not be awakened by the alarm sound, or to those who may be incapable of safely evacuating the area unassisted.
