The XP95 Base Sounder Visual Alarm Device (VAD) is a loop powered sounder and VAD combined with a standard intelligent mounting base. It is used to signal a fire alarm in enclosed areas.
The volume range is switch selectable during installation stage. 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 certified to AS7240-3 for general use when the higher volume range is selected.
Synchronisation of tones ensures the integrity of the 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 acoustic self-test means that the sounder listens to itself when it is switched on. If no sound is detected a fault signal is transmitted when the sounder is polled. The VAD self-test is achieved by means of an LED monitoring circuit. If the LEDs do not draw current when the Base Sounder VAD has been switched on a fault signal is transmitted to the control panel when the device is next polled.
