The SA-400M Classic Mechanical Siren


The SA-400M Classic Mechanical siren is aptly named. Building on the foundation of the “industry standard” SA-400 Classic, this next generation siren combines the rugged dependability of its predecessor with a classic Mechanical Tone, powerful new Carson “Stutter” Air Horn and distinctive silver look. The result…a premium siren that effectively clears intersections by delivering that “Big Engine” sound that makes drivers instinctively pull over.

Call response time, safety and the reduction of accidents when in route to calls are top priorities for all first responders. With the SA- 400M Classic Mechanical, you’ll have the peace-of-mind to Run Fast, Sound Big and Arrive Safe!

The SA-400M Classic Mechanical 100/200- watt siren features a rotary switch for selecting siren tones and radio, a momentary push button for the air horn and Manual siren control, a master on/off switch, a noisecancelling PA microphone and a large PA volume control knob. The siren also features LED backlighting and the Horn Ring Cycler (HRC) function that enables hands-free control of the siren by cycling through the tones using the vehicle’s horn. This is ideal during pursuit or rescue situations.
