Overview
The Pertronic Sounder Base (PSBAS2220) is an
analogue addressable plug-in detector base with built-in
sounder. The PSBAS2220 generates a tone when the
detector is in alarm, or when directly activated by a bell
circuit.
The PSBAS2220 communicates with any Pertronic
analogue addressable fire alarm control panel via the AA
loop. The base connections connect the sounder base to
the analogue addressable loop, and internally to the LED
drive output of the analogue addressable detector.
When the detector is in the alarm state, the sounder base
generates NZS 4512:2010 Appendix F evacuation or alert
signals, depending on the position of switch S1. (Switch
S1 is accessible only when the unit is removed from its
mounting base.)
The unit may also be powered from a supervised bell
or sounder circuit via the SNDR IN terminals. If the
bell circuit is activated, the evacuation signal will be
generated, irrespective of the detector status.
The PSBAS2220 is normally mounted by recessing it
into the ceiling. A mounting ring is available for surface
mounted applications.
