Good Afternoon,

I just wanted to provide some positive feedback on your team with specific regards to Emma Williams in Export Sales. I work for a Facilities Maintenance company that is based both in the UK and Ireland which as I’m sure you can imagine; especially in the current climate can be challenging when it comes to stock.

I first started using your site last year and since then have always been welcomed with the most efficient delivery and quick response on stock required for our FA Technician.

Nothing is ever too much trouble and I just wanted to forward this feedback on to yourselves so it was brought to your attention and more importantly to say thank you.

Kind Regards,

Ceri

Kidde Airsense EST-CU-11LT Control Unit (11 control slots)

EST–CU-11LT Control Unit (CU) is a matrix mixer of input signals which routes to 4 x 100 V internal audio buses, a 45-channel digital system buses or directly to audio outputs in a unit. EST-CU-11LT is designed to work for small PA & VE systems or as an extension unit in more complex systems. It means that the CU can function independently as the central unit of a small system or be part of a large complex system for which it represents another level of either territorial extension (operation in a remote structure) or functional extension (operation of further fire zones and loudspeaker lines in such a structure).

The modular design of the CU and its flexibility enables optimization of equipment and cost efficiency regardless of size / number of structures, their location and connectivity.

In the event of losing connectivity with a networked master unit, ESTCU-11LT is able to perform fire alarm scenarios independently thanks to the configuration recorded locally. While attached to the main communication ring of the system, EST-CU-11LT can control amplifiers and power supply managers as well as receive alarm and digital signals; and send them to other system devices.

EST-CU-11LT Control Unit distributes audio signals to individual zones and ensures that individual zones function properly. It also controls the condition of loudspeaker lines and amplifiers.

If a fault is detected, it sends the signal to the system and automatically switches to a backup amplifier. The CU is equipped with an EST-cAudIO-4/12 card offering 4 symmetrical line audio inputs and 12 symmetrical outputs to lead audio signals out to external devices or amplifiers of the EST ENT VES system.

Key Features

  • Compliance with EN54-16
  • Network-based system allowing configuration, diagnostics and
  • management via Ethernet
