Pertronic PSSB401 is a 100V Line Speakers (1.1 W max) which integrates a 1 W speaker, line transformer and dc blocking capacitor. The enclosure is designed to support a System Sensor B401 Conventional base and detector. When used in conjunction with the Pertronic 20W and 50W 100V line amplifiers it provides a cost effective solution for speaker based building evacuation systems that comply with NZS 4512:2010.

The PSSB401 has links for selecting the 0.2 W, the 0.7 W, or the 1.1 W power output. At 1.1 W and with Pertronic’s 100 V amplifiers, the PSSB B401 can reproduce the evacuation tone at a sound pressure level of 97 dBA at 1 metre.
