    The 851/001 series intercom allows for up to 40 master handsets to selectively call and speak with each other and a maximum of four (4) simultaneous conversations.

    The Alpha Communications®/Elvox™ 851/001 series intercom system is a digital encoding/decoding multiple conversation system for up to 40 master stations. Each model 851/001 master handset can call up to 39 other masters, by means of easy, two digit pushbutton calling. Up to four (4) completely private conversations can take place at one time. Duplex voice switching eliminates background noises. Because the encoding is digital, each unit is a master, thus eliminating the need of a centralized exchange unit, making this system easy to install and very cost effective. Additional masters can be added at any time without the need for any additional power supplies or central equipment, or adaptors. Station numbers are assigned by means of programming clips. Other features include: paging through a PA system, communication with an outdoor station, electric door release, etc.

    All 851/001 master stations have calling buttons numbered 1 through 10 and A through D. In addition, a paging and door release button is standard. Calling to another master is accomplished by depressing a letter (A-D) and a number (1-10), for a total of 40 possible combinations. The model 851/001 master is designed to mount right on the surface of the finished wall, or can be desk mounted with an optional model 2/805 desk adaptor.

    A wide variety of remote stations is available in ABS plastic, extruded aluminum, stainless steel, polished brass and painted finishes.

    Used primarily for upscale residential use, the Crown Jewel allows the door or gate to be answered from any telephone in the house Polished Brass or Stainless Steel finish.

    Crown Jewel Telephone Entry Intercom System

    Crown Jewel Series

    The Crown Jewel system is a single-line telephone entry system that connects directly to the resident's telephone line. Thus, the residence is called without the system having to dial through the telephone company's central office. As a result, the Crown Jewel does not generate telephone charges either on a monthly or per call basis.

    The Crown Jewel is capable of carrying out the following functions:

    1. Visitor entry: The visitor presses a "#" on the system's keypad. This switches the resident's telephone line to the system and rings the resident's telephone. The resident can then communicate with the visitor and allow entry at the main door or gate by dialing a "9". If the system is controlling a second door or gate, the resident would dial "5" to allow entry at that location.

    2. Call waiting: If the telephone is in use when the visitor presses the "#" key, the resident will hear 2 short tones to signal that a visitor is attempting to call. The resident can then dial a "2"and the outside call in progress will be put on hold and the telephone will be connected to the visitor. If the resident allows entry (as described above), he/she will be automatically switched back to the outside call in progress.

    The resident can also deny entry, hang-up the visitor, and switch back to the call in progress by dialing a "". Alternatively, if the resident is talking with a visitor and the resident receives a normal phone call, he/she will hear two short tones at which point he/she can put the visitor on hold and switch over to the normal phone call by dialing a "2" and back again to the visitor by dialing a "2"again. If the resident forgets that either the visitor or the normal phone call was left on hold and the resident hangs up, the resident's phone will ring (up to three times) with the call that was left on hold. The resident just picks up the telephone and continues his/her conversation with the party that was put on hold.

    3. Entry codes: The resident (and anyone else he/she authorizes) can have a unique 4-digit entry code. When this code is entered on the keypad, it will cause the door to open. The Crown Jewel can have up to 50 different entry codes programmed into it.

    4. Gate/door monitoring: The installer can place sensors on the gate or door that the system controls to monitor the status. You can program the Crown Jewel to respond in one of the following ways if the gate/door is forced open or is held open 60 seconds after it should have been closed.

    a. Alarm call: The system will first call a pre-programmed outside telephone line and send a message via modem. If there is no modem at the pre-programmed number or no answer after 60 seconds, the system will call the resident. If the resident does not have a modem, he/she will hear a series of tones after answering the phone. Pressing any key on their tone dial telephone will acknowledge someone has received the alarm call and the system will connect the answering phone to the Crown Jewel and activate the audio so the answering phone can talk through the system (for example, to ward off intruders). If you do not wish to be connected to the Crown Jewel, do not press a key on the telephone keypad and hang up the receiver.

    b. Close a relay: If relay 2 is programmed as an alarm relay, the system will close that relay to activate a device the installer has connected to it (for example, a siren).

    5. Free exit through a monitored gate: The system can provide free exit through either controlled entry to allow exit without causing a forced open door condition.

    6. Auxiliary Keypad: An auxiliary keypad, located in a smaller but matching housing to the Crown Jewel's, can be connected to the Crown Jewel system for additional access control (for example, to control the ability to exit through a gate).

    7. Direct resident control of doors/gates: The controlled doors or gates can be activated directly from the resident's tone dial telephone.

    8. Resident originated communications: The resident can originate communications through the Crown Jewel at any time that an outside call is not in progress by picking up his telephone and dialing "##6". This call will terminate automatically in 60 seconds unless the resident hangs up sooner, or the resident extends the talk time by pressing the "1" key.

    9. Resident Remote Programming: The Crown Jewel system can be remotely programmed from the resident's tone dial telephone.

    10. Off-Site Remote Programming: The Crown Jewel system can be remotely programmed from any outside tone dial telephone.

    11. Remote Diagnostics: The Crown Jewel system can be called using a terminal connected to a Hayes-compatible modem or personal computer running terminal emulation software connected to a Hayes-compatible modem. You can then access information concerning the system's operating perimeters and the entry codes programmed into the system.

    12. Call forwarding: The Crown Jewel system can be programmed to call an outside telephone number when a visitor presses the "#" key on the front panel of the system. This will enable you to allow access to a visitor from a remote location.

    13. Intercom Operation: The Crown Jewel system can be used as an in-house intercom by allowing any phone in the house to call other phones in the house using a distinctive ring. When called, all phones on the same line will ring simultaneously. The station intended to be answered will know it should answer because the phones will ring the number of times equal to the number assigned to that station by the resident. Additionally, the Crown Jewel will provide this feature even if there is no telephone line present from the phone company.
