The MS-1 Mute Switch is an accessory to Louroe Audio Monitoring/Audio Surveillance Systems when microphone muting is required. The MS-1 contains a built-in rocker switch mounted to a single gang stainless steel face plate. This is to mute or disable the audio feed to a base station or other receiving and recording devices. It prevents the operator from listening in to the microphone when it is not needed, The MS-1 fits into a single gang backbox (not included) for mounting to a wall or flat surface.
The MS-1 ML (p/n LE-333) adds a Normally open (NO) single pole single throw (spst) relay output to allow for muting a “mic” level microphone such as the Louroe A-ML or can be used to connect to any input that requires a “dry” contact output, such an the alarm input to a camera or access control system.
