Product Details

The W-2000A is a handsfree doorbox in a surface mount light grey UV stable plastic chassis. It is designed to interface directly with an unused analog telephone line input of phone system. One or two W-2000A doorboxes can also share an existing phone line when used with a C-1000B doorbox controller.

When the “Call” button is pressed, the W-2000A generates a standard or custom ring cadence with an adjustable number of rings. For noisy environments, the W-2000A’s louder speaker output and “Push-to-Talk” feature can be used.

For outdoor installations where the unit is exposed to precipitation or condensation, use model W-2000A-EWP. For more information on Enhanced Weather Protection (EWP), see DOD 859.
