Fire-Lite SLC-2LS two-loop signaling line circuit card for compatible Fire-Lite addressable panels.

Key features

• Adds a second SLC loop to compatible Fire-Lite addressable fire alarm panels
• Designed as a direct plug-in expansion card for supported panel models
• Increases total device capacity by adding a second independent SLC circuit
• Replacement card for systems where the original SLC card has failed

Signaling line circuit (SLC) cards are the core interface between an addressable fire alarm control panel and its field devices. Each SLC loop can support a defined number of addressable detectors, modules, and notification devices. The SLC-2LS is a two-loop card that adds or replaces SLC loop capacity in compatible Fire-Lite panels — critical when a system is being expanded beyond the capacity of the original single-loop installation, or when an existing card requires replacement due to component failure. Confirm the host panel model and slot availability before ordering.

Verify panel/device family compatibility before ordering.
