Horn Speaker, 10 Watt, IP66, AS ISO 7240.24


The Horn Speaker, IP66, 10 Watt (CF2053G) is a high-efficiency AS ISO 7240.24-certified 100 Volt-Line speaker designed for emergency warning systems. It is more than seven decibels louder than a cone-type speaker with the same input power.

Adjustable power taps provide sound level adjustment to meet project requirements such as area coverage and ambient noise level.

The rear cover is attached with a twist-lock mechanism. This provides tool-free access to the screw terminals, to save time when terminating the cables.

The offset mounting bracket can be installed without detaching the speaker.

The enclosure is made from tough UV-stabilised flame-retardant ABS.

To ensure compatibility with commonly-used fire evacuation systems, the speaker incorporates a series blocking capacitor and 100 Volt-Line transformer.
