Frequently asked questions
Common questions about FEDERAL SIGNAL from 3G Electric.
What voltage options are available for Federal Signal tower light modules?
Federal Signal tower light modules, such as the LSL series, are available in common industrial voltages including 24V AC/DC and 120V AC. The MSL3 series assemblies also offer 24V AC/DC and 120V AC variants. For specific applications, verify the operating voltage of the module or assembly before installation to ensure compatibility with your facility's power supply.
Can Federal Signal LSL tower light modules be used in outdoor environments?
Federal Signal LSL tower light modules are typically rated for indoor use, but some configurations may have IP ratings suitable for protected outdoor areas. Check the specific module's datasheet for ingress protection (IP) ratings. For outdoor or washdown applications, consider Federal Signal's weatherproof enclosures or select modules explicitly rated for such conditions.
How do I replace a lens on a Federal Signal LSL tower light module?
Federal Signal LSL tower light modules feature snap-on lenses that can be replaced without tools. To replace a lens, gently pry off the existing lens using a flathead screwdriver or similar tool, then snap the new lens of the desired color (e.g., amber, blue, green, red) into place. Ensure the module is de-energized before performing any maintenance.
What is the difference between Federal Signal LSL and LSLD series tower light modules?
The Federal Signal LSL series modules are standard tower light modules with steady or flashing operation, while the LSLD series modules are designed for dual-function operation, typically offering both steady and flashing modes in a single unit. The LSLD-120G, for example, provides a green lens with selectable modes. Both series are compatible with the same mounting bases and sounder tiers.
Does Federal Signal offer sounder modules for their tower light systems?
Yes, Federal Signal produces sounder modules such as the LSH-120, which is a horn sounder tier compatible with LSL series tower lights. This module operates at 120V AC and produces a steady audible alert. It can be integrated into multi-tier assemblies to provide both visual and audible signaling for alarm or status indication.
