UK distributor Switchtec has launched a range of fully sealed audible alarms suitable for use in industrial environments.

Various sound options are available including constant, sweeping and pulsating tones.

Power consumption is low, and the units are designed to operate from a 12 to 250V AC or DC supply, depending on model.

The 04 Series is particularly suitable for use in noisy environments, as it has a loud output of 104dB at a distance of 1m.

Furthermore, the unit has a wide operating range from -40 to +80C.

Frequency range of the tones is from 2.4 to 2.9kHz - in the middle of the human hearing spectrum where the ear is most sensitive.

Featuring a sealed construction to IP65 and an operating range from -30 to +60C, the Sonartone Series is ideal for use in harsh environments.

With no moving parts and solid-state circuitry, Sonartone is a highly reliable sounder.

The unit generates no RF noise or electrical interference, meaning that it can be mounted near to sensitive equipment.

Particularly useful during installation, the DC units will not be damaged by accidental reverse voltages under 28V.

Measuring 50mm diameter for the 04 Series and 43mm for the Sonartone range, both units can be either front of panel or base mounted as required.

Connections are via fly-leads or terminal screws.
