Base Module for LED Alarm Stack

The Federal Signal SLMBD-120-240GY is a gray base module designed for SLM series LED alarm systems. It operates on 120 to 240VAC and provides the foundation for stacking visual and audible signal modules in industrial or commercial environments.

Deep Surface Mount with Listed Approvals

The base mounts directly to a deep surface using standard hardware and measures 3.9063 in wide by 3.9063 in deep by 1.8125 in high. It carries UL Listed, cUL Listed, CE Certified and RoHS Compliant markings, simplifying compliance for panel builders and facility engineers.

Continuous Duty at Rated Voltage

The module is rated for continuous operation across the full 120 to 240VAC range without derating. Internal components are selected for sustained load rather than intermittent signalling, so the base maintains stable power delivery to stacked modules during extended alarm events.

Questions about this item

How can I confirm the SLMBD-120-240GY base is operating correctly after installation?

Apply 120 to 240VAC power and verify the LED indicator illuminates steadily; the UL, cUL, CE and RoHS markings confirm compliance when the unit is energised.

What components are included with the SLMBD-120-240GY and what must be purchased separately?

The package contains the SLM base module in gray; mounting hardware, light modules, lenses and wiring are not included and must be sourced separately.

Which voltage version of the SLM base should I select for my supply?

The SLMBD-120-240GY covers 120 to 240VAC in a single unit, so no separate voltage variant needs to be chosen.
