Functions: plena end-of-line boards monitor the presence of a pilot tone on loudspeaker line. Fits on built-in mounts selected Bosch loudspeakers. This signal is always present on the line: when back ground music BM playing, a call in progress, and no. Daisy chain able for monitoring multiple zones on a single input contact.
This allows a loudspeaker line with several branches to be monitored. Features: pilot tone detection on 100 v loudspeaker lines. The board connects at the end of a loudspeaker line and detects 20 khz pilot tone signal. Presence of the pilot tone signal does not depend on number loudspeakers line, load or line capacitance.
Several eol boards can be daisy-chained to a single fault input. The 20 khz tone is inaudible and at a very low level -20db. It activates a voltage free switch in the presence of 20 khz signal pilot tone above 5 v, as well an led for easy visual confirmation operation. When the pilot tone fails, contact opens, and led goes off.
When the pilot tone signal is present, an led lights up, and a contact on board closed.
