The fixed location callbox allows school to position wireless communication at delivery doors, entry/exits, playground etc. eliminating costly trenching and construction associated with wired solutions, according to the company.
The callbox has an internal antenna, is weather-proof and can operate completely standalone on D-cell batteries, eliminating all wired connections.
A built-in relay can be used for access control applications such as gates, doors or for activating an emergency strobe light.
