1801-004 DoorKing Power Supplies and Transformer

Providing intercom, entry and directory services to apartment complexes, residence halls and condominiums.

Many intercom/telephone entry systems feature:

• "Call Down" capability: Allowing residents to directly connect with an operator or concierge.
• Access Control: Often with the push of a button on a telephone

Intercoms, telephone entry systems and directories are most commonly used in apartment complexes, residence halls and condominiums, among other applications. In some cases, including many of DoorKing's available items, tenants/residents do not need a central office phone service to be connected. Instead, a touchtone telephone plugged into the wall jack can provide an immediate connection.
