The innovative S-Quad range of multi-sensors combines the most advanced sensing technologies with alarm functionality. Fires are detected using a range of sensing elements; heat and smoke and CO. Using patented dual angle optical scatter S-Quad offers reliable detection and enhanced false alarm reduction.

In addition, each variant of S-Quad is available as a sensor sounder and many with strobe or voice enhanced function. This makes S-quad ideal for providing a safe and effective alarm system with simple compliance with the needs of the DDA (Disability Discrimination Act) Use of programmable sensitivity states means S-Quad can be configured to address specific known risks such as steam and dust, allowing it to significantly reduce potential false alarms.

This unique range also offers significant cost savings; with up to four separate functions in one device (sensor, sounder, strobe and speech) means less cabling is required than with separate devices. As is expected of the Vigilon loop S-Quad functions are all loop powered and connect to the standard 2-core detection loop circuit with short isolation as standard. A further "hidden" saving is delivered by the standard LED output that may be configured as a monitored input output that can be used instead of an interface.
