FireAngel Low Frequency Sounder



The Low Frequency sounder has a wireless module which is activated by the radio signal that the Wi-Safe 2 (WST-630) smoke alarm sends when it detects smoke. A Low frequency sounder is more likely to wake up high risk individuals such as children, those with mild to moderate hearing loss, older people and people under the influence of alcohol than a regular smoke alarm. The low frequency sounder can be wall mounted horizontally or vertically or freestanding offering greater flexibility in positioning.


You can test the entire wi-safe installation in your home by pressing the test button on any part of the system...this is particularly useful for people with limited physical ability.


The low frequency sounder is mains powered with a rechargeable battery backup, and also features fault, power and alarm indicators.
