'DPK' Series Compact Door Phone Intercom Kits

The Alpha Communications®/S.T.R.™ 'DPK' series intercom kits are a low cost alternative to conventional apt. or entry intercom systems for 1, 2 or 3 inside handset stations. Each inside handset station requires only two (2) wires from the door station.

The ultra-compact door station is only 3.25" (83mm) wide and has a built-in voice amplifier. It easily mounts right on the surface of the wall and has a built-in rain hood. There are no visible mounting screws from the front, and built-in L.E.D.(s) illuminate the push buttons. All that is required to power the system (and door opener) is a plug-in transformer (included in each kit).

The optional PK407A door opener relay allows connection to other voltages and types of door openers.
