Understanding Weatherproofing for Your Fermax Device
When you install a premium Fermax intercom or door station on the exterior of your property, you expect it to withstand the elements. However, understanding the difference between "weather-resistant" and "waterproof" is crucial for ensuring the longevity of your device. This guide explains what the ratings mean and how to protect your investment.
Understanding IP Ratings (Ingress Protection)
The key to a device's weather resistance is its IP rating. This is a standardised international rating that tells you exactly how protected the device's enclosure is against the intrusion of solids and liquids.
An IP rating consists of two numbers:
- First Digit (Solids): This number, from 0 to 6, indicates the level of protection against solid objects, from large body parts down to microscopic dust particles. A 5 means it's dust-protected, and a 6 means it's completely dust-tight.
- Second Digit (Liquids): This number, from 0 to 8, is the most important for weatherproofing. It indicates the level of protection against moisture.
- IPX4: Protected against splashing water from any direction. This is generally considered the minimum for outdoor use.
- IPX5: Protected against low-pressure water jets from any direction.
- IPX6: Protected against powerful water jets.
- IPX7/8: Protected against temporary or continuous immersion in water (i.e., waterproof).
Most Fermax outdoor stations carry a rating like IP54. This means it is protected against dust ingress and can withstand splashing water (rain). It is not designed to be sprayed with a high-pressure hose or submerged in water.
What to Do If You Suspect Your Fermax Isn't Weatherproof
If you are experiencing issues with your device after heavy rain, or if you are concerned about its placement, here are some key steps to take.
1. Check Your Specific Model's IP Rating
Not all Fermax products are designed for direct exposure to the elements. Some indoor monitors or older models may have no weather protection at all. Always verify the IP rating for your specific model number in the product's technical documentation or on the Fermax website. If you have installed a non-weather-rated device outdoors, it should be moved to a protected location immediately.
2. Inspect the Installation and Sealing
A proper installation is vital for maintaining weather resistance. The device's IP rating is only valid if it has been installed according to the manufacturer's instructions.
- Gaskets and Seals: Ensure that all rubber gaskets and seals provided with the unit are correctly in place and not pinched, cracked, or damaged. These are critical for keeping water out.
- Cable Entry Points: The point where cables enter the back of the unit is a common failure point. Ensure this area is properly sealed. Installers should use weatherproof glands or apply a suitable outdoor-grade silicone sealant to prevent water from wicking along the cables and into the device.
- Mounting Surface: The unit should be mounted on a flat, even surface to ensure the rear housing sits flush and the seals can do their job effectively.
3. Add Physical Protection
Even a high-IP-rated device can benefit from additional physical shielding, which can dramatically extend its operational life.
- Install a Rain Shield: Fermax and third-party companies offer rain hoods or shields specifically designed to fit over door stations. This is a highly recommended accessory that provides a cover against direct downpours and also helps to reduce sun glare on the camera lens.
- Strategic Placement: When possible, install the unit in a location that offers some natural protection, such as under a porch roof, in a recessed doorway, or under the eaves of the house. This reduces the amount of direct weather exposure it must endure.
4. What Not to Do
- Do NOT Power Wash: Never use a pressure washer or a high-pressure hose to clean your Fermax device. This can force water past the seals and cause catastrophic damage, which will not be covered by warranty. Use a damp cloth to clean the unit.
- Do NOT Submerge: Fermax door stations are not designed to be submerged in water.
By understanding your device's limitations and ensuring it is installed correctly and protected from the harshest conditions, you can ensure your Fermax system remains a reliable part of your home security for years to come.
