Each LS unit contains its own power amplifier, receiving its DC power from the system master via the comms line wiring. For example, a system could be constructed using an MS741 Master Loudspeaker Station, where two-way communications took place on circuit A, while circuit B was used as a paging circuit.

To ensure important announcements are always heard, LS200 loudspeakers can be triggered (irrespective of where the volume control has been set) to default to a preset audio level when a 28kHz 'Override' control signal is received from a MS741 Master Loudspeaker Station.

LS400 and LS600 loudspeakers do not respond to 'Override' commands.

Suitable for use with Series1 and Series 2 products.

Note: Only the MS741 Master Loudspeaker Station can generate the 28kHz 'Override' signal.
