FW821H

DESCRIPTION
The FW821H input-output module provides one 24VDC output and one feedback input switch. The input line is monitored for open line faults and ground faults, and the contact must thus be wired with an end-of-line resistor. The output line is monitored for open line, short circuit faults, ground faults, and external 24VDC power source loss. It is a UL listed device according to UL864 and ULC-S527 for Fire Protective Signaling Systems for indoor use.
The device LED flashes once every 3 seconds at normal condition. When the output is activated, the LED will perform a longer flash every 3 seconds. When the input is activated, the LED will flash twice every 3 seconds. When both output and input are activated, the LED will turn steady on.
A return to normal condition will cause the event to disappear and the device LED indicator will return to the red idle condition.
The FW821H is an intelligent addressable module and takes one address on the Signaling Line Circuit (SLC) or Data Communication Link (DCL) of the fire alarm control panel.

ATTENTION
The products must be installed in accordance with the NFPA 72, the CAN/ULC‐S524, and the Canadian Electrical Code depending on the country of installation. Check information of equipment used in the system by other manufacturers for any guidelines or restrictions.

INSTALLATION
1.Mount the FW800 base onto a 2X4 or 4x4 electrical box using the screws provided, as illustrated in Figure 1.

Figure 1. Installation Diagram

2.Connect the wires, see Figure 2. There is polarity sensitive between terminal 1 and terminal 2, between terminal 3 and 4, and between terminal 5 and 6. All circuits are power-limited. The maximum line impedance for Feedback input circuit is 25 Ω and the maximum line impedance for output circuit is 1 Ω. External input power supply is either PCU AUX output of FACP or Listed 24VDC Regulated/power-limited source with ground fault detection.). Example of compatible device: door strike, Model 0563 from RUTHERFORD CONTROLS IN’L INC., with “Fail secure” mode. Acceptability should be determined by Authorities Having Jurisdiction.

4.Combine the assembled unit to the base using the screws provided.
5.Apply power to the control unit.

PROGRAMMING
The module must be programmed to a valid address before use. A valid must be in 1~252 and cannot be duplicate with other device in same loop. Refer to the manual of hand-held programmer ReadWritor FW411 and panel FW106 to set the device address. Disconnect wire at terminal 1 and 2 before programming. Disconnect wire at terminal 1, 2, 3, and 4 before programming.
TESTING
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.Trigger the input switch to activate a feedback signal. The LED should turn to red fast blinking. Check the event occurrence displayed on LCD of the controller and verify it.
4.Restore the input switch to normal position. The LED should turn to red idle condition. An output signal will display on the FACP AMI interface.
5.Activate the output (you may need to first make a related control logic on the control panel). The LED should turn to red fast blinking.
6.Deactivate the output. The LED should turn to red idle condition.
7.Once the testing is completed, set the system back to normal operation and inform proper authorities.

MAINTENANCE
Return the module for repair if it fails to flash or alarm during testing. Do not disassemble the module without permission.
