Product Overview
The Integrated Base Sounder comprises a sounder with integral detector mounting base and has been designed to signal a fire alarm in enclosed areas. The sounder is line powered requiring no external power supply and is designed for internal use. Alert and Evacuation sounder tones complying with the recommendations of AS7240-3 are incorporated which are fully programmable for staged evacuation within the LoopSense and FireFinder control panels. The low volume range is useful in areas such as hospitals where a fire alert is initially intended to warn staff only. The sounder is set to high volume range for general use. Synchronisation of tones ensures the integrity of the alarm signal/tones from different sounders do not merge into one signal that could be mistaken for a different tone. For systems requiring isolators at every point the built-in isolator saves installation time and cost. The built in acoustic self-test enables the sounder to listen to itself when it is switched on and if no sound is detected, a fault signal will be transmitted when the sounder is polled to the control panel. The sounder base can be used either with a detector fitted or with a cap for operation as a stand-alone alarm device.
