The LP Symphoni range of Sounders and Sounder Beacons are designed to operate on the robust MZX digital loop,

An internal line isolator automatically provides short circuit protection against able faults thus reducing the need for

additional line isolator modules.

The addressable loop powered sounders meet the

requirements of EN 54-3 whilst the loop powered

addressable sounders with beacon are also approved to

EN 54-23 as open category devices.

A high (103 dB) output or low (90 dB) output can be

selected for any of the 16 selectable tones.

Programming has been simplified by allowing the tone,

volume and flash rate to be set by the MZX Consys

configuration utility. This means adjustments to the settings can be achieved without having to access the sounder location. Changes can be made to all sounders by a single panel software download which saves time and reduces commissioning costs.

Reflective Sound Monitoring is employed to monitor the

audio output of the sounder. This is particularly beneficial

during regular weekly sounder tests.

RSM allows the system to listen for audibility whenever the

sounders are operated and the MZX Technology panel will

alert the user if any sounders fail to operate.

Failure of the beacon would also generate a fault at the MX

control panel.
