What Sentry Siren does
Sentry Siren, Inc. is a privately held, family-operated U.S. manufacturer of outdoor warning sirens and complementary emergency-notification systems, headquartered in Penrose, Colorado (relocated from Canon City, CO in June 2020). The company traces its origin to Sterling Siren and Fire Alarm, founded in 1905, and operates today under the leadership of Bill Yarberry (President/CEO) and W. Scott Yarberry (SVP/COO). It produces hand-built, omni-directional electro-mechanical sirens spanning roughly 107–131 dB(C) output and 1,700–6,100 ft coverage radii across models such as the 3V8, 7V8, 10V, 14V/14V-B, 15V2T, 16V1T-B, 20V1T, and flagship 40V2T, alongside industrial sirens (F-2, E-4, E-6, ER-1, ER-5, EV-5) and the SV-8 electronic High-Powered Speaker Array.
The technology stack is anchored by proprietary manufacturing techniques — Single Ingot Sampling rotor/stator production, custom-built fan-cooled continuous-duty motors, zinc-galvanized/phosphatized/powder-coated enclosures, and field-programmable Generation-series controllers (Gen-1, Gen-3, Gen-5) paired with motor starters, VFDs, and lightning arrestors — and is bundled with two software modules: Storm Sentry, which interprets National Weather Service data to automate siren activation, and Sentry S.T.A.R., which provides real-time telemetry and report-back for deployed units. The company claims the lowest failure rate in the industry, a five-year 100% parts and labor warranty, and 25+ year (often 40+ year) service life.
Sentry generates revenue through one-time hardware sales (quote-based, pricing not publicly disclosed), one-time Storm Sentry software purchases, factory recertification/refurbishment services, custom siren design and manufacturing, and grant-writing assistance. Distribution is almost entirely direct, with customers reached via a U.S. toll-free line, a contact form, field sales representatives across the country, and optional on-site visits by Sentry designers who produce complimentary interactive 3D Google Earth coverage maps. Primary customers are municipalities and communities in tornado-prone U.S. states, with secondary segments in schools, military and government agencies, and fire/industrial facilities; the company also claims worldwide reach via website inquiries.

Sentry Siren product offering
Product offeringCore offering
Sentry Siren manufactures and sells outdoor warning sirens (both electro-mechanical and electronic/Giant Voice models), industrial sirens, siren controllers and accessories for municipalities, schools, military bases, and industrial facilities. The company also develops and licenses proprietary software including Storm Sentry weather monitoring/activation software and Sentry S.T.A.R. real-time system telemetry software, complemented by complimentary siren system design services.
Product overview
Sentry Siren is a single-vendor warning-systems manufacturer (not a multi-module SaaS platform) offering three integrated product lines that are typically sold together as a turn-key solution: (1) outdoor warning sirens — both electro-mechanical omni-directional sirens (the 3V8, 3V8-H, 3V8-H-B, 7V8, 7V8-B AC/DC, 10V, 10V1T, 14V/14V-B, 15V2T, 16V1T-B, 20V1T, and flagship 40V2T) and the SV-8 electronic/Giant Voice high-powered speaker array; (2) industrial sirens (F-2, E-4, E-6, ER-1, ER-5, and voice-capable EV-5); and (3) siren control accessories including the Gen-1, Gen-3, and Gen-5 controllers, "S" Series motor starters, variable frequency drives, and pole mount brackets. The hardware is paired with two complementary software modules: Storm Sentry for automatic severe-weather siren activation based on National Weather Service data, and Sentry S.T.A.R. for real-time field telemetry and report-back, which depends on the Gen-5 controller. Sentry also provides a complimentary Siren System Design Service that produces Google Earth coverage maps with siren placement recommendations.

Sentry Siren competitors and assessment
Company assessmentDirect peers
- Federal Signal Corporation: Federal Signal is a publicly listed industrial and municipal signaling equipment manufacturer with a direct outdoor warning siren line (e.g., 2001 series), competing head-to-head with Sentry in municipal tornado alerting and industrial signaling for similar community, government, and industrial buyers.
- American Signal Corporation: American Signal Corporation is a direct U.S. competitor in the outdoor warning siren market, selling electro-mechanical and electronic sirens to municipalities, military bases, and industrial sites — overlapping with Sentry on product type, customer segment, and GTM motion.
- Whelen Engineering Company: Whelen Engineering manufactures emergency vehicle warning lights and sirens as well as mass-notification speaker arrays (WPS series), serving public safety, emergency response, and outdoor warning markets with comparable electromechanical and electronic product lines to Sentry Siren.
Broad incumbents
- Eaton (Cooper Notification / Wheelock): Eaton owns the Cooper Notification and Wheelock notification appliance brands, offering broader fire alarm and mass-notification portfolios that overlap with Sentry's industrial siren and SV-8 Giant Voice lines, but as part of a much wider building safety product set.
- Honeywell (NOTIFIER): Honeywell's NOTIFIER fire alarm and emergency communication systems serve the same municipal, campus, and industrial buyers as Sentry Siren, with broader integrated building-safety portfolios that include audible/visual notification appliances overlapping Sentry's product range.
- Siemens Smart Infrastructure: Siemens Smart Infrastructure delivers building technologies including fire safety and mass notification systems, competing with Sentry at the integrated-solution level for large campus, airport, and industrial emergency alerting projects.
Emerging players
- Bogen Communications: Bogen Communications manufactures paging, public address, and emergency notification equipment for schools, commercial buildings, and industrial facilities — an adjacent product set to Sentry's industrial sirens and SV-8 Giant Voice system, focused on voice-based notification rather than mechanical sirens.
- Valcom: Valcom provides IP-based mass notification, paging, and emergency communication systems for K–12, healthcare, government, and industrial facilities — competing with Sentry's electronic/Giant Voice SV-8 in the software-defined notification segment.
