Kidde - Edwards VM-SLCXB2 Signaling Line Expansion Card

Product Description

The KIDDE - EDWARDS VM-SLCXB2 is a signaling line circuit expansion card designed to extend the addressable loop capacity of compatible fire alarm control panels. This type of card integrates directly into the control panel chassis, allowing additional SLC devices such as smoke detectors, heat detectors, and modules to be connected and supervised. Installation is performed by licensed fire alarm technicians working within systems governed by NFPA 72. The VM-SLCXB2 supports scalable system design for facilities requiring expanded device coverage beyond the base panel capacity.

This expansion card is suited for commercial and large-scale residential fire alarm applications where addressable signaling line circuits must be extended. It is typically installed in new construction or during system upgrades where additional loop capacity is required. Facilities such as office buildings, multi-family structures, hospitals, and institutional buildings commonly use SLC expansion cards of this type to accommodate higher device counts across one or more floors or zones.

Key Features

• Expands addressable signaling line circuit capacity on compatible fire alarm control panels
• Supports connection of additional addressable detectors and modules
• Designed for direct integration into the control panel chassis
• Enables scalable system design for larger or growing facilities
• Sold as a single unit for targeted capacity expansion

Compatibility

Designed as an OEM-style expansion card for use with compatible KIDDE - EDWARDS fire alarm control panel systems. Refer to the panel installation documentation to confirm SLC expansion card slot availability before ordering.

Installation Notes

Installation of this expansion card must be performed by a licensed fire alarm technician in accordance with NFPA 72 and all applicable local codes. Power down and fully discharge the fire alarm control panel before inserting or removing any expansion cards. Confirm that the host panel firmware and hardware revision support the VM-SLCXB2 prior to installation. Do not install this card while the panel is energized or while the system is in active alarm condition.
