The Cooper (Eaton) FXN824 is an aesthetically pleasing, low-profile sounder base engineered to streamline fire alarm installations by combining detection and notification at a single mounting point. Capable of functioning as a standalone unit or paired with an Eaton conventional detector, it provides a high sound output of up to 90dB(A) with three selectable tones to ensure clear emergency signaling. This EN54-compliant device is optimized for low power consumption (typically 9mA) and features a slim white plastic housing that blends seamlessly into commercial environments like hotel bedrooms and offices. With its simple two-wire connection and polarized circuit supervision, the FXN824 offers a reliable and unobtrusive solution for 24V DC conventional fire systems. Technical Specifications ?
