Ambient System’s product line includes dozens of fire speakers. Each of them complies with the EN 54-24 standard and features a variety of applications.
The range includes loudspeaker columns, ceiling speakers, wall-mounted speakers, surface mounted speakers, , sound projectors, horn speakers, high-power speakers and tunnel loudspeakers.
The possibilities for their application range from facilities that require complex sound systems to simpler ones that allow easier and more economical solutions.
In case of an emergency, the Voice Evacuation System needs to guide people in the tunnel to safety so the audio transmission should be as clear as possible. In general, due to high levels of reverberation and noise, a tunnel is not an ideal environment for Voice Evacuation System and therefore speech intelligibility becomes a critical parameter for any voice alarm application.
To establish a sufficient level of speech intelligibility, a highly directional speakers system is required. By reducing the energy emitted to other surfaces, reflective sound energy can be minimized which results in a better direct to reverberant ratio. This will improve the maximum feasible speech intelligibility.
To minimize disturbing echo effects, resulting in a loss of speech intelligibility, each horn speaker is driven by an individual signal channel in a 100 V installation, which is equipped with audio DSP including EQ and delay. Our product S4T (Safety For Tunnel) offers the most effective solution which seamlessly combines a dedicated Voice Evacuation System with tailored Tunnel Loudspeakers.

ABT-BS140 and ABT-BS220 are digitally beam steering line arrays. Thanks to the use of a multi-channel digital signal processor DSP, the implemented algorithms will modify the directivity of the emitted sound and model the shape of the acoustic beam, adapting it to the acoustic conditions in the audience area.
Using the beam steering feature, these line arrays will reach large distances with a highly uniform sound pressure level precisely covering a greater area per speaker.
ABT-T2520A is an active horn loudspeaker with a built-in 20 W amplifier designed to work with security systems. It is an ideal choice for applications in security systems, industrial and commercial systems in both outdoor and indoor. Built-in 20 W amplifier powered with 12 V voltage has an audio line-in input.
It allows to connect the speaker directly to CCTV camera. Built-in internal volume control of gain allows you to choose the appropriate volume level of the broadcast message.
ABT-W6S / ABT-S206S / ABT-T2515S active SIP speakers with built-in amplifiers are a family of network speakers that support the SIP protocol (G.711 A/U, G.722) and multicast. These speakers, can be powered from 12-24VDC, or by PoE, allowing easy connection to existing local networks using single CAT5 / CAT6 cable connection.
ABT-W6S can be mounted either on a wall or on a ceiling. Additionally, it can be fixed as an recessed speaker and therefore it is an ideal solution for rooms where aesthetic factors play a significant role. ABT-S206S is a ceiling speaker that has been designed to guarantee the highest acoustic parameters. ABT-T2515S is horn SIP speaker with built-in 15W amplifier. The high efficiency and directionality of ABT-T2515S allow broadcasting voice messages directly to even distant places, while ensuring a high sound pressure level. The aluminium housing guarantees increased resistance to adverse weather conditions provided by the IP65 rating.
