Wet location exit signs are defined by the fact that they are sealed from the possibility of water or moisture entering them and damaging internal circuitry. By definition, they must be capable of being exposed to direct rainfall, without any risk of damage. On the other hand, damp location signs require partial protection from above; whether that protection comes from a canopy, marquee or roof.

Wet Location LED exit signs are waterproof and designed for outdoor use.

Construction of Wet Location Exit Signs

Typically, wet location waterproof exit signs are built with a more rugged case than inexpensive thermoplastic exit signs. There are also a number of vandal proof models available. Vandal proof signs are made with heavy aluminum cases, to protect them from damage by being struck. Even our self-luminous exit signs are waterproof and also completely non-electrical

Possible Locations for Wet Location Exit Signs

The exterior of buildings where the route to a public way is not obvious
Internal courtyards, where the building goes around the courtyard and there are egress points dumping into the courtyard
Loading docks
Vehicle fueling and maintenance areas
Areas between closely spaced buildings on a campus, where the public way is not obvious
Exterior industrial areas, such as chemical processing

Cold and Wet Locations

Since wet locations are essentially exterior locations, one must also take into account the possibility of freezing temperatures. While many electrical components are essentially immune to cold; batteries, and important part of exit signs, are affected by excessive cold. If you are in an environment where freezing temperatures are encountered, you should have the internal heater option installed. This heater, while small, is enough to maintain the battery temperature above freezing, where it is capable of working correctly.

Advantage of Purchasing Vandal Proof Signs

Vandal proof exit signs are waterproof and can handle high levels of abuse..

Any exterior application for a wet location exit sign is likely to be within the reach of vandals. As such, there is a regular risk of damage to these signs especially in central areas of large cities, where vandalism is common. Because of this, the extra investment for vandal proof signs is easily justified as a means of both protecting your investment and protecting the personnel of your company from having an exit sign that is destroyed, at the time of an emergency evacuation from the building.

Maintenance of Wet Location Exit Signs

As with all other exit signs, wet location exit signs must be tested on both a monthly and an annual basis.

Monthly tests consist of interrupting the power for 30 seconds, with the integral test switch and verifying that the light stays lit. Visual inspection for damage and visibility of the sign is required as well.
Annual tests add a full 90 minute power off test, to verify that the unit stays lit for 90 minutes. The unit must be opened, so that both the battery and charge circuit voltages can be checked. Be careful to not damage the case seal in the process of opening and resealing the sign. The unit must be cleaned at this time.

Other Options for Wet Locations

Self-luminous exit signs will also work in wet locations. You may want to consider installing this type of sign, instead of installing standard wet location exit signs as their is no electrical requirement.
