Fire-Lite SLC-3LS 318-Point Addressable SLC Signaling Line Circuit Expander Card for ES-1000X

Streamline and scale fire detection infrastructure with the Fire-Lite Alarms by Honeywell SLC-3LS addressable loop expander module. Designed for ES-1000X (Endurance Series) control panels, this control panel module adds an additional SLC communication loop and supports up to 318 addressable devices per card — letting you extend coverage without replacing the base panel. Install up to two SLC-3LS cards to achieve three SLC loops and a system capacity of 954 points, ideal for larger commercial, multi-tenant, or campus environments.

For systems integrators and facility managers, the SLC-3LS reduces labor and wiring complexity while maintaining reliable monitoring and reporting to your existing fire alarm network. Its compatibility with Fire-Lite control panels ensures predictable configuration and robust performance for life-safety, security, and surveillance applications. Whether you’re upgrading an older installation or planning phased growth, this expander module delivers cost-effective scalability and simplified maintenance. Add the SLC-3LS to your ES-1000X setup to increase device density and improve overall system responsiveness — contact your supplier to configure and order.
