Standard Horizon MLS410LHB Intercom Speaker — 5", Black
The Standard Horizon MLS410LHB is a 5" external intercom speaker with a PTA (Push to Alert) button, designed specifically for use with the Standard Horizon VLH-3000A 30W Dual Zone Loudhailer. It is not compatible with VHF radios. When connected to the VLH-3000A, pressing the PTA button on the speaker sends an alert signal to the loudhailer unit, notifying the operator to switch to intercom mode for two-way communication between stations.

Parts Desk Insights
Best Use Case: The MLS410LHB is the correct intercom speaker for VLH-3000A installations where a secondary station — such as a flybridge, cockpit, or engine room — needs two-way intercom capability with a PTA alert function. It is the right choice when the operator needs to signal the helm from a remote location before switching to intercom mode, rather than using a standard PA speaker that only receives audio.
