Telephones shall be mounted in such a way that they can easily be replaced using special mounting screws.
Since telephone wiring may enter the telephone box from different locations (top, bottom, side, back), the telephone box must be large enough to accommodate a half-inch conduit to the point of entry on the instrument itself in order to minimize vandalism, sabotage, or intentional disconnection. If a housing is used, it should have a minimum two-inch clearance at the bottom, top, and sides of the telephone box. If the housing has a door, it should be at least a half inch from the front of the phone so that it does not interfere with the push button.
The TRE As-3 telephone is configurable for multiple options, including switching of external AC power to serve external accessories such as a strobe light. Note: UCSB Communications Services does not support AC switching configurations.
Emergency telephone instruments must:
- Allow for hands-free usage.
- Be placed at a height of 48" at the button.
- Be telephone line powered.
- Be compatible with Centrex dial tone or PBX battery.
- Be programmable for "off hook" activation to a ring down circuit.
- Be capable of being called back directly without going through a programming options menu.
- Withstand extended exposure to a harsh coastal environment, especially salt air.
- Use a standard telephone jack and not be hard wired.
