For harsh environments

Using the electronics of its established A Series, the D range is housed in a robust, corrosion resistant LM6 aluminium alloy enclosure, giving greater mechanical, temperature and UV protection than an equivalent plastic bodied device.

The D105 is rated at 112 dB at 1m and the D112 at 117 dB at 1m; both types are also available combined with a Xenon strobe or LED beacon to generate both an audible and visual alarm from a single unit.
