The Discovery Sounder Visual Indicator Base is designed for sensitive environments like hospitals, where a low-volume fire alarm alert is essential. It features an integrated isolator for easy installation and cost efficiency, while its synchronised tones ensure the integrity of the fire alarm signal. The acoustic self-test function provides added safety, automatically detecting faults in the sounder when activated. This ensures that the sounder always remains reliable.
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 the high range for general use. 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. Group addressing is a simple method of alerting an entire area or group of rooms without delay.
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 beacon self-test is achieved using an LED monitoring circuit. If the LEDs do not draw current when the sounder beacon base has been switched on a fault signal is transmitted when the device is next polled.
