Features:
EN 54-16 Certified Plena End of Line Monitoring Board
A Plena end-of-line board is a PCB designed to detect the 20 kHz pilot tone generated by a supervised public address or voice alarm system. It activates a voltage free switch in the presence of a 20 kHz signal (pilot tone) above 5 V, as well as an LED for easy visual confirmation of operation.
Features:
Pilot tone detection on 100 V loudspeaker lines
Voltage free switch 200 V 1 A and LED indications of pilot tone
Daisy chainable for monitoring multiple zones on a single input contact
Fits on built-in mounts on selected Bosch loudspeakers
EN 54-16 certified
