EWP

Enhanced Weather

Protection

March 18, 2008

Standard practice for manufacturing emergency or entry phones is to provide

them with standard uncoated circuit boards (like the ones in your PC). A few

manufacturers, including Viking, spray the circuit boards with a water resistant

material such as acrylic conformal coating to protect them.

Some emergency or entry phone applications demand extra protection.

Phones that are mounted outside exposed to the elements in salty air near the

ocean, exposed to a corrosive atmosphere or vehicle exhaust all need an

extra measure of weather and corrosion resistance. See “Does my installation

require Enhanced Weather Protection” below.

Our EWP (Enhanced Weather Protection) phones are designed with total reli-

ability in mind. First, we use weather-sealed push button switches, trim pots

and DIP switches so you can adjust microphone and speaker volumes and set

programming features right at the installation site.

Then, we hand solder all wires to eliminate the kind of corrosion that can

occur in ordinary electrical connectors. We also hand seal the connec-

tions at the push button switch, microphone, and "Call Connected" LED

using a special non-corrosive silicone sealant. We use a special micro-

phone boot that acts as a shield against water penetration. A mylar speak-

er is used with rubber mounting gasket. Closed cell foam gasketing is

used behind front panels to prevent water penetration.

Finally we "Pot" the entire board in a clear flexible urethane encapsulating material leaving

the internally sealed field-adjustable trim pots and DIP switches accessible. Our flexible ure-

thane sealant allows the circuit board and it’s components to expand and contract, while

maintaining weather resistance. To protect the tip and ring connections, we include connec-

tors filled with anti-corrosive sealing gel.

• Urethane potting for:

- Maintaining flexibility at low temperatures

- Excellent electrical insulation

- Low stress on sensitive components

- Unaffected by moisture at high temperatures

- Thermal cycling ability

- Hydrolytic stability

- No shrinkage

• Internally sealed push button switch, dip switches and volume

control pots

• All wire connections are hand soldered and watertight sealed

• Mylar speaker with weather-proof rubber gasket

• Closed cell foam gasketing to prevent water penetration

• Weatherproof connectors filled with anti-corrosive sealing gel

• Back side of push button switch, LED and microphone are

encapsulated in watertight sealant

• Self-draining microphone boot

Does my installation require

Enhanced Weather Protection?

If you answer “yes” to one or more of the following statements, we

recommend a Viking emergency or entry phone with EWP

(Enhanced Weather Protection).

1. The product is located outside near the ocean.

2. The product is mounted to a gooseneck pedestal with full

weather exposure.

3. The product is mounted in a parking garage with vehicle

exhaust.

4. The product is mounted near a swimming pool.

5. The product is mounted outside on a boat, dock or pier.

6. The products wire runs use conduit which could funnel warm

inside air to the product mounted outside, causing condensa-

tion on the circuit board.

7. The product is mounted in a location with a known corrosive

atmosphere.

8. The product is mounted outside with the wire entering the top

of the chassis without a wire drip loop.

9. The temperature of the product can get below the dew point.

• Exposure to harsh elements (outdoor emergency phones)

• Exposure to a salty atmosphere near the ocean (beach, boardwalk or lifeguard emergency phones)

• High-humidity environments (tropical environments and areas where it gets very hot and humid)

• Corrosive-atmosphere environments

• High-pollution environments

• High-vehicle exhaust environments (roadside assistance and emergency phones)
