The Model RE-2 Residential Telephone Entry System is designed for residential or light commercial access control applications. The speakerphone, keypad, radio receiver, and optional video camera are housed in a rugged enclosure that can be mounted to a pedestal, or bolted directly to a wall, or flush mounted in a column. The diecast keypad keys have bright, easy-to-read graphics and are lit with an overhead light. The two operation buttons; CALL and HELP, are machined for heavy-duty reliability. Optional CCTV color camera can mount inside.

Arriving visitors will approach the unit and place a call to the residence by pressing the CALL button. The RE-2 will acquire the residence's local telephone line and generate distinctive rings to the house telephones. The resident, knowing that the distinctive ring is originating from the access area, can answer any house telephone and converse with the visitor. If the resident decides to grant access to the visitor, they can activate either output relay in the RE-2 by pressing a key on the telephone's keypad. If the resident decides not to grant access, hanging up or pressing a key will disconnect the visitor's call.

If the resident is using the telephone at the time a visitor calls, the RE-2 will sound beeps on the telephone line to announce that a visitor is calling. The resident can press a key on the telephone to place the outside caller on hold and communicate with the visitor. After granting or denying access to the visitor, the outside caller will be re-connected to the resident.
