UL listed, two-wire, non-polar, quick respond to smoke produced by different combustible material. The built-in high-performance microprocessor can self-test, analyze and diagnose the detector state.
The FW511 is an intelligent Smoke Detector used with the FW500 Detector Base, is a UL listed device according to UL 268 and ULC-S529 for Fire Protective Signaling Systems for indoor use. It features a slim design which combines visual appeal with a high standard of reliability. It responds quickly and dependably to a broad range of fires. The detector has a Microcontroller Unit (MCU), performing comprehensive self-diagnostic tests and result analysis. The FW511 is intelligent, addressable, and takes one address on the Signaling Line Circuit (SLC) of the fire alarm control panel.
The products must be installed in accordance with NFPA72, CAN/ULC-S524, and/or Canadian Electrical Code depending on country of installation. Check information of equipment used in the system by other manufacturers for any guidelines or restrictions.

1.Mount the FW500 base onto a 2x4’’ electrical box, see Figure 1. The installation hole pitch is illustrated in Figure 2.  

                                    Figure 1. FW500 Base Installation                                  Figure 2. Wiring Terminals and Pitch of Hole

2.Wire the SLC to the detector base, as illustrated in Figure 3. There is no polarity distinction between terminal 1 and terminal 2.

3.Set the detector address (1-252). Use the hand-held Programmer ReadWritor FW411. Refer to the FW411 Manual.
4.Put the detector onto it’s base and secure it into position by turning clockwise.
5.Apply power to the control unit to activate the SLC.

1.Before testing, inform the proper authorities that the system is undergoing maintenance and will temporarily be put out of service. Disable the system to prevent unwanted alarms.
2.Make sure the indicator LED on the detector’s surface is flashing. Failure to flash indicates a non-functioning detector or a faulty wiring. Check the wiring and remount the detector.
3.Go/No Go Field Test: Use the aerosol, Solo A4. The LED on FW511 should latch steady-on and the system should go into alarm.
4.Once the testing is completed, set the system back to normal operation and inform proper authorities.
The detector needs to be tested on a regular basis. Refer to the Testing section for more information about the procedure. The detector has an automatic-drift-compensation feature to provide accurate-sensitivity detection. When the drift is out of range, the “Device _GeneralTrbl” trouble will be displayed on the FACP, which means the sensitivity may be outside the limits and the detector needs cleaning.
1.Before cleaning, notify the proper authorities that the system is undergoing maintenance and will be temporarily out of service.
2.Disable the system to prevent unwanted alarms.
3.Remove the detector to be cleaned from the system.
4.Remove the detector cover and the maze cover.
5.Use a vacuum cleaner or compressed air to remove dust and debris from the maze.
6.Reinstall the detector.
7.Test the detector as described in the Testing section.
8.Notify the proper authorities that the system is back on line.

Figure 4. Cleaning

Return the detector for reparation if it fails to flash or alarm during testing. Do not disassemble the detector without permission.
