Emertronic — a Polish manufacturer of warning systems

Siren amplifiers and signal controllers

A siren amplifier is the electronic siren of an emergency vehicle: it generates warning tones at 100 or 200 W and drives the speaker through a class-D amplifier. EMCORE amplifiers combine the siren and the light controller in one enclosure — a single device runs the vehicle's entire warning system.

EMCORE ULTRA — siren and light controller in one

A 12/24 V amplifier rated 100 or 200 W with 6 high-current channels ×10 A (Σ 30 A) — a central signaling controller driving the bar, directional lights and traffic advisor from a single control head. Over 30 warning tones (custom messages possible), a microphone with public-address (PA with PTT), radio rebroadcast and Bluetooth.

EMCORE MICRO — the same power, smaller size

A 100/200 W amplifier in a compact aluminum housing with 3 ×10 A channels — for quads, motorcycles, boats and vehicles with limited installation space. Operated from the control head or via analog body buttons.

A siren for ambulances, police cars and fire apparatus

A police siren-and-lights system with stealth detection (unmarked vehicles), a PURSUIT button and horn-ring control (hands-free). Fire and ambulance sirens use the same 500–1800 Hz path, and the ADAPTIVE variant automatically matches the light mode to the tone the operator is already using.

A complete acoustic path

The amplifier pairs with THUNDER 100 W / 11 Ω speakers, and adding the REZON low-frequency module extends the band to 150–500 Hz — felt inside sound-insulated cabins. The whole path — amplifier, speaker, wiring — comes from one manufacturer.

  • 100 W with a single speaker is enough for passenger vehicles in urban traffic; 200 W (two speakers) is chosen for heavy vehicles and high-noise work. Both ratings are available in EMCORE ULTRA and MICRO — the difference concerns only the audio path.

We will match a configuration to your vehicle.

Describe the vehicle and the fleet's duties — we will propose a set with the full type-approval documentation.
