Kidde V-SLC2-1 Single Loop Controller Card

The Kidde V-SLC2-1 is a plug-in Signature loop controller that adds one Class B or Class A intelligent device loop to any VS4-series fire-alarm control panel or replaces the original 64-point loop card in a VS1 panel. Board includes on-board isolation, automatic device mapping, and supports up to 250 addressable points (125 detectors + 125 modules) on VS4 systems. When fitted in a VS1 it functions strictly as a service replacement, maintaining the panel’s original 64-point capacity without providing expansion. Key Specifications: Application: Loop expansion for Kidde VS4 panels; service-replacement loop card for Kidde VS1 panels Loop Capacity: 250 addresses on VS4 • 64 addresses on VS1 Wiring Style: Class B (Style 4) or Class A (Style 6/7) selectable Operating Voltage: 24 V DC supplied by host panel Current Draw (fully loaded): Standby 55 mA   Alarm 80 mA Terminal Size: 12 – 18 AWG conductors Maximum Loop Resistance: 66 Ω    Maximum Loop Capacitance: 0.5 µF Isolators per Loop: Up to 64 (bases or modules) Environmental Range: 32 – 120 °F (0 – 49 °C); 0 – 93 % RH non-condensing Compatible Host Panels: VS4-G • VS4-GD • VS4-R • VS4-RD — loop expansion (one card per expansion slot, max two single-loop cards or one dual-loop card) VS1-G • VS1-GD • VS1-R • VS1-RD — service replacement only (keeps 64-point capacity) Related Accessories: V-SLC2-2 – 500-point dual-loop controller (alternative expansion card) Note: Use of the V-SLC2-1 in a VS1 panel is intended for like-for-like board replacement and does not expand the panel beyond its original 64 addresses. For additional point capacity a VS4 control panel is required.
