The LC7004 Dual Loop Card by Tanda is an expansion module for compatible addressable fire alarm control panels. It adds two detection loops, with each loop supporting up to 254 addressable devices. As a result, one card can expand the system by up to 508 addressable points.
The LC7004 works with compatible Tanda fire alarm equipment, including the TX7004 series. In addition, it monitors loop wiring for open and short circuit faults. This helps technicians identify wiring problems during system operation.
First, a qualified installer mounts the module in an available slot of a compatible fire alarm control panel.
Next, the installer connects the approved addressable loop wiring to the card’s removable terminals.
When the system starts, the control panel automatically assigns the loop number. Therefore, technicians do not need to set a separate loop-card address.
During operation, the module communicates with connected addressable devices. It also monitors the transmission path for wiring faults.
If an open or short circuit occurs, the card reports the fault to the control panel. As a result, maintenance teams can identify the affected loop more easily.
The LC7004 Dual Loop Card is useful when a fire alarm installation requires more addressable device capacity.
Common applications include:
However, the final design must follow the control panel’s supported capacity and applicable fire safety requirements.
The LC7004 is designed for compatible Tanda addressable fire alarm systems.
For example, each added loop can connect supported optical smoke detectors, heat detectors, manual call points, and alarm modules.
However, the module does not operate as a standalone fire alarm control panel. It requires a compatible host panel for monitoring and control.
