Robust metal-bodied sounders and beacons for harsh environments

For use in harsh environments where high temperatures, shock and vibration or high UV levels are anticipated, E2S has introduced the new D range of alarm sounders and combined sounder/beacon warning signals.

Using the electronics of its well-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 112dBA at 1m and the D112 at 117dBA 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.

Testing has proven that a metal housing offers far greater protection at elevated temperatures than a plastic enclosure and is especially suited to outdoor applications such as mining conveyors where high ambient temperatures and sustained vibration can be experienced.

Both units offer a choice of 45 different alarm tones, and with the option of activating a second and third tone via additional control cables, they are a cost effective sophisticated signalling solution that offers the versatility of multiple tones from a single unit at a lower cost.

The devices can operate from 12V, 24V and 48Vdc as well as 115V and 230Vac. A UL approved version is also available.
