DPH20521A Single Line Wall/Desk Telephone

The Alpha Communications® DPH20521A single line telephones are designed to work as an apartment type telephone intercom station, in conjunction with a telephone entry type intercom system, or for other similar applications.

The DPH20521A single line telephones are also ideal for use as "Dummy Phones" on "No-Phone-Bill" type telephone entry intercom systems, where the apartment tenant does not have a telephone connected to the phone company lines or phone service, or as Concierge telephones for use with our AlphaEntry™ type intercom systems.

These stylish phones easily surface mount on the wall or on a table or desktop. The Lighted Keypad allows its use in dark rooms or at night.

The Flashing RED Indicator Lamp Bar makes the DPH20521A telephone a perfect solution for hearing-impaired users, who cannot hear the normal electronic ringer.
