Alarms

Alarms — New & Used

Industrial alarms (including audible, visual, and combo units) alert operators, technicians and safety systems to abnormal conditions, process faults, or system faults. Available in beacon, horn-strobe, panel-mount, surface-mount and explosion-proof designs, they play a vital role in plant safety, monitoring, and automation feedback.

At Surplus Select, we stock a rotating selection of new and used OEM alarms, including industrial signal lights, horns, sirens, and combination alarm units. Our surplus pricing allows maintenance teams, OEM integrators, and control panel builders to source trusted signaling devices without paying full catalog prices.

Fast U.S. Shipping — Most orders ship same or next business day from our U.S. warehouse to keep your line running.

Find Your Alarm Fast (Search-First)

Search your part number or model (e.g., HDS-22 Beacon, horn-strobe combo 120 V, panel signal light 24 V DC).
No PN? Try specs like “audible alarm horn strobe”, “surface mount beacon 24 V”, or “industrial panel alarm 120 V AC”.
Need a specific type or rating? Add details such as explosion-proof, NEMA 4X, LED beacon, or sound output dB to your search.
