Product Description

100v line remote volume control for loads of 100W with provision for local volume restoration for paging announcements by built-in 24v relay override.

The control has been designed to provide excellent frequency
response with minimum quiescent power loss, using uniquely wound auto-transformers for maximum efficiency.

LVC100 model includes all the same features of the standard LVC-25; the main difference is that the override relay is energised when the Volume Control is in normal use and de-energises in fail/safe override condition, to provide full volume restoration for emergency broadcasts.

The LVC100 is suitable for low frequency and DC line surveillance monitoring systems, normally associated with Voice Alarm facilities and are site adjusted.
