ESL 500 Series
Smoke Detector
Installation Instructions
Description
The ESL 500 Series Smoke Detectors offer 2-wire, 4-wire, 12VDC, and 24VDC detectors for fire system applications.
Depending on the model, the smoke detector provides the following features:
Detector/base lock
Discourages unauthorized removal of the smoke detector by requiring a screwdriver to remove the detector from the base.
CleanMe®
Enables the control panel to receive a warning signal via a 505 module, or CleanMe compatible panel, indicating that the optical chamber needs to be replaced. This feature is available on the 521/ 528 Series 2-wire detectors only.
The detectors ship with the CleanMe feature turned off. To turn on the CleanMe signal move DIP switch 2 on the back of the detector to the “on” position. See Figure 1.
1.On=A (6-12V) range Off=C (12-24V) range
2.On=CleanMe signal on Off=CleanMe signal off (521/528 Series only)
Note
Turning the CleanMe signal on without using the 505 module and/or compatible panel will create a trouble signal.

Selecting a Location
Selecting a suitable location is critical to the operation of smoke detectors. This equipment should be installed in accordance with the National Fire Protection Association’s (NFPA) Standard 72.
A-8-1.2.1.a Where to Locate the Required Smoke Detectors 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 detector(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 detector(s) should be located as shown in Figure 2 A.
In family living units with more than one bedroom area or with bedrooms on more than one floor, more than one smoke detector is required, as shown in Figure 2 B.

Self-diagnostics
Includes automatic sensitivity testing. Once a day and immediately upon first power up, each 500 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.
Drift compensation
The detectors automatically adjust sensitivity, up to a maximum of 1.0%/ft., as the detectors become dirty.
Using the 2-wire 521/528 Series with a panel that does not have 2- wire capabilities
The ESL 505 module can convert the 2-wire 521/528 Series to a 4- wire input on the control panel. The 521/528 Series is UL Listed as compatible with the 505 module and will be fully UL compliant with any UL listed 24 VDC control panel and panels that do not operate below 12V. Each 505 module will accommodate up to 20 ESL 521/ 528 Series smoke detectors. See the 505 module installation instructions for more information.
Selectable voltage range for UL 2-wire compatibility
The 500 Series 2-wire smoke detectors have a DIP switch that allows the installer to choose between 12/24V operation and 6/12V operation. See Figure 1 and Specifications.

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 2 C. The living area 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 detector should be placed on the bottom of the joists. The detector should be positioned relative to the stairway to intercept smoke coming from a fire in the basement before the smoke enters the stairway.
A-8-1.2.1.b Where to Locate the Required Smoke Detectors in New Construction. All of the smoke detectors specified in A-8-1.2.1.a for existing construction are required and, in addition, a smoke detector is required in each bedroom.
A-8-1.2.1.c 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.
Important: Regulations pertaining to smoke detector installations vary from state to state. For more information, contact your local fire department or local authority having jurisdiction.
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 inches (10cm) from any walls or partitions.
•Locate wall-mounted smoke detectors so the top of the detector is 4 to 12 inches (10 to 30cm) below the ceiling.
•Do not locate detectors in or near bathrooms or kitchens.
•Locate in a suitable environment as follows:
-Temperature between 32°F (0°C) and 100°F (37°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 detector.
•Mount smoke detectors on a firm permanent surface.
Figure 3. Detector/base lock
Installing the Detector
All wiring must conform to the National Electric Code (NEC) and/or local codes having jurisdiction. Use 12 to 24 AWG 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 3.
2.Remove the red plastic cover from the detector. The detector is shipped with a cover for protection against construction site dust.
3.Run system wiring to the detector location and mount electrical boxes if necessary.
4.Line up and attach the gasket (if the detector comes with a gasket) and mounting base to the electrical box, wall or ceiling using the screws provided. Use the wall anchors if necessary. See Figure 5.
5.Strip the system wires and connect them to the appropriate terminals on the detector. See Figure 6.
6.Attach the detector to the mounting base as follows:
-Line up the raised tab on the side of the detector with the arrow on the mounting base. See Figure 4.
-Insert the smoke detector into the base and turn clockwise approximately 15 degrees. It should snap firmly into place.
7.Apply power.
8.Test the detector. See Smoke Testing the Alarm.
Figure 4. Mounting
Smoke Testing the Detector
Smoke detectors should be tested in place annually using smoke or canned aerosol simulated smoke. Follow the instructions on the canned smoke or use the following steps to test the detector with smoke:
1.Hold a smoldering punk or cotton wick close to the smoke entry openings.
2.Gently direct the smoke into the detector for 20 seconds or until an alarm is indicated.
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.
