PRA-EOL
PRAESENSA End-of-Line Device
Compact end-of-line supervision device for PRAESENSA loudspeaker lines, using a low-level 25.5 kHz pilot tone so the amplifier detects line faults without extra wiring.
Description
The PRA-EOL is fitted at the end of a loudspeaker line so the PRAESENSA amplifier can confirm the whole line is intact. It uses a low-level, high-frequency pilot tone, so faults are detected in the amplifier without extra supervision wiring, which makes it a reliable solution for long loudspeaker lines.
The device is small, has a thermal fuse for protection, and can be mounted in several ways, including inside a loudspeaker or junction box.
Trinity Solutions supplies, programmes and commissions Bosch PRAESENSA public address and voice alarm systems across the UAE, including integration with fire alarm, IP telephony and BMS.
