Page 6: Introduction
Each ONE unit consists of an EN54-16 system capable of controlling a maximum of 6 zones and delivering a maximum total power of 500W. In addition, it is possible to create larger systems by linking several ONE units, allowing the control of up to 60 zones with an overall power of up to 5000W. -

ACSI bus and its devices. Optionally, a system can be made up of more than one unit. In this case, the first unit must have a redundant system link card (ONE-LOOP) installed in its expansion bay. For more information on the connection of these types of systems and their configuration, see respectively section 2.2.11 and section 3.5. -
Page 8: Hw And Fw Versions
1.3 HW and FW versions For the operation of the expanded ONE system, ONE devices must have a serial number over 20xxxxxx and have their firmware updated to version v02.00.01.00 or higher. You can check for firmware updates on the LDA support website. -

Page 21: Advanced Mode Selection
3.2.3 Advanced mode selection By activating the advanced mode, the user will be asked if he wants to configure the speaker line outputs in A + B mode. The following sections explain the process that the unit will perform automatically. a) Speaker lines and zones. -
Page 22: Manual Configuration.
e) Backup amplifier The backup amplifier and the supervision of amplifiers are automatically activated. The unit will flag a fault if any of them stops working at any time, or if it does not offer the appropriate level of gain. f) Setup Report At the end of the process, the number of detected zones and lines and the number of installed ACSI devices are displayed on the screen. -
Page 23: Audio Outputs.
b) Input 3. Input 3 Input intended for background music. The menu includes the same functions as sources 1 and 2, except for the parameters that configure the activation mode (“Trigger Mode” submenu). c) Mixer input, Input 4 - MIX. The mixer is a tool allowing you to work with priority sources, such as microphones, without cutting the background music. -
Page 24: Speaker Lines Configuration.
c) VA Rec-Out: This control allows activating the “recording output” or “rec-out” mode. When active, pre-out output 4 will no longer be linked to a zone and will instead play live voice messages broadcast to the evacuating zones. (Ex: Manual messages in VAP-1 panels) 3.3.3 Speaker Lines configuration. -

◦ Loopback FLT: It establishes the supervision of the return link (from the last unit to the first one in the network). If this option is disabled, the system will stop monitoring this link, and it will not flag a fault if it is not operating. -
Page 31: Individual Configuration Of Each Unit
3.5.2 Individual configuration of each unit The system will be constituted as the grouping of each one of the units that compose it. These units must be previously configured separately, as if they were independent systems by themselves. The individual configuration of each unit can be achieved in two ways, the simplest will be by running the autosetup process where the unit will detect the connected lines, battery, etc. -
