Calibration Technologies SL-24-F-GAR-B LED Stack Light

The Calibration Technologies SL-24-F-GAR-B LED Stack Light is a 24 VDC, three‑color signaling module (green, amber, red) with an integrated buzzer, designed for high‑visibility alarm signaling in industrial safety and gas‑detection systems. It combines three LED light modules in a single stack, offered in 24 VDC (and 120 VAC) configurations, with a maximum draw of 40 mA per LED module and a 180 mA buzzer; the green module is non‑flashing in the GAR configuration while amber and red provide flashing indicators for at‑a‑glance status, and the unit supports a separate horn and light circuit for flexible wiring or configurations. Built for rugged environments, the housing is polycarbonate, rated IP64, UL listed, and designed to withstand corrosion, weather, and washdown; mounting options include panel mounting or 1/2" EMT conduit mounting using two mounting adapters for easy installation. Operating across a wide temperature range from -22°F to +158°F, the LEDs are specified for about 50,000 hours of life, and audible signaling delivers roughly 100 dB at 10 ft with a 2.5–2.9 kHz tone; the device also supports user‑selectable horn tones (continuous or temporal) to match your safety signaling needs. This 24 VDC GAR‑B configuration is purpose‑built for rapid, multi‑color status indication in gas alert or process‑safety applications while maintaining reliability in demanding plant environments.
