Rainbow has a range of analogue and SIP telephones designed for arduous environments. Weather and vandal resistance are standard, whilst the ability to customise the design and application gives you exactly the product you need.

Extreme environments demand superior performance, which is why you'll find our products and systems installed in safety critical and arduous locations worldwide.

All Rainbow Help telephones are CE compliant and are manufactured under ISO9001, ISO14001 and OHSAS 18001. Some products have other specialist approvals - for more information on these, see full product brochures.

Operating temperatures allow you to gauge whether the telephone is suitable for your needs. Whether it will be sited in direct sunlight or out in the snow and ice, Rainbow outdoor telephones are reliable, even in environmental extremes.

IP ratings show how resilient a product is to ingress from dust and water. This is important when the telephone will be sited outside or in industries. Rainbow help point telephones are designed and built to perform, and to last, in harsh conditions and heavy industrial environments.
