Product Information

This product has been discontinued and is for information purposes only.

The SONA WSM-SN-1 is a 230V mains powered smoke detector, with tamper-proof sealed for life battery back-up and both wireless and hard-wired interlinking capabilities. Under typical usage conditions, it uses approximately 10% less power than the average AC fire alarm, making it the only smoke detector currently on the market with a proven carbon footprint. The back-up battery boasts a lifespan of 10 years.

Its integrated ultra-slim mounting base ensures easy installation, and its tamper-resistant hinge prevents the detector unit being removed without a suitable tool.

'Sleep Easy' functionality enables the low battery chirp to be silenced for an 8 hour period (this function can be used up to a maximum of 10 times). The alarm can be temporarily silenced for up to 10 minutes in the case of a known false activation, however if the level of smoke detected is very high, this feature will be overridden for your safety and the alarm will continue to sound. When the combined test/silence/locate button is pressed on any device on the network, all connected devices except the device that was triggered will be silenced, offering easy identification of the unit in alarm.

This product provides Class A1 smoke detection, and is appropriate for use in Grade D systems. It is approved to
BS EN 14604:2005, ETSI EN 300 220-2 V2.3.2 (2010-02), EN300489-1 &-3 and EN300220-2 - Radio. The manufacturer warranty period is 5 years.

Interconnection

This versatile alarm is ideal for use in mixed systems, which means that it can be linked wirelessly with up to 50 compatible devices, as well as up to 30 units via hard-wiring with 3 core and earth cable. When any device on the system is activated, the 85dB sounders will sound on every other interlinked unit.

Thermoptek Technology

Designed to respond quickly to both fast flaming and slow smouldering fires, this product employs Thermoptek technology, which constantly monitors for temperature change and provides an early response if the temperature is predicted to rise above a predetermined threshold.
