Product Description

The Panasonic KX-TA824 Advanced Hybrid system is expressly designed to maximize home communications in your home. With its wide array of features, it offers the functions of both a telephone system and an intercom system, plus a whole lot more.

The KX-TA824 offers a variety of options to enable customized solutions. You can assign specific lines to each phone, make room-to-room intercom calls at the touch of a button, forward your calls to an outside location, monitor a room, page all system extensions, enjoy conference calls, and more. So you can tailor your telephone system to the varied needs of your household.

This powerful combination of flexibility, high performance and value has made Panasonic Communication systems number one in Key Telephone/Hybrid systems.


The KX-TA824 system works with standard telephone lines, so you don't need to upgrade your phone service. It features a base configuration of three central office lines and eight stations. It can be easily expanded to up to eight central office lines and 24 stations with the addition of two plug-in cards (models KX-TA82470, KX-TA82483 and KX-TA82481).

The system comes out of the box equipped to support 3 outside lines and 8 extensions. By installing optional expansion cards the system can grow to a maximum capacity of 8 outside lines and 24 extensions. A maximum of two expansion cards of any combination can be installed in the system. All of the expansion cards are provided with modular connectors for easy connection of outside lines and extensions.

Backward Compatible
The KX-TA824 control unit is compatible with all Panasonic KX-T7700 series telephones, KX-T7800 series cordless telephones, industry standard single line telephones (SLT), and fax machines without adding any special hardware to the control unit. The system is also backward compatible allowing you to connect older, Panasonic KX-T7000 and KX-T7300 series telephones.

Room-to-Room Intercom
The KX-TA824 Advanced Hybrid Telephone System's Room-to-Room Intercom takes the place of a traditional intercom while offering easy operation and a host of home conveniences. You can call any room in the house from any telephone in the house. And with the convenient Auto Answer function activated, the person you called may reply without even picking up the telephone. If you're finishing up some important paper work in the home office, this feature lets you speak to family members without leaving your desk.

Flexible Line Buttons
You can use the central office (CO) line buttons on each proprietary telephone to access a CO line or you can program them for one-touch operation of system features like intercom calling, speed dialing or paging. With the KX-TA824, dialing from room to room is extremely easy. Simply lift the receiver and press the button that is assigned to the room you wish to call. For additional convenience, the different buttons may be clearly labeled via built-in designation strips.

Flexible Ring Assignment
This feature allows you to dictate which outside lines will ring on each phone. For instance, you can program business lines to ring in the office, and personal lines to ring in the bedroom, kitchen, etc. And if you have a separate line for your children, you can program it to ring only in their rooms.

Room Monitor
This great feature allows you to monitor your children's activity from any system phone in the house. So you can go about household chores while keeping an ear on the kids. The room being monitored must contain a proprietary system phone with a built-in speakerphone.

Consolidate your conversations and save time with the call conferencing feature. It allows you to combine two calls from two different lines, so you can talk to both parties at the same time. This feature is great for the home office, and also comes in handy for personal use as well. For instance, parent/teacher discussions can include mom and dad simultaneously with the use of this feature.

Night Day and Lunch Mode Settings
Using this convenient function, each telephone line in the home can be set to one of three modes (night, day, or lunch) based on changes in operation over the course of the day. You dictate flexible ring assignments and the class of service for each line. For example, you can program night mode so that when you go to bed, only the phone in the master bedroom will ring. Or you can set the system to lunch mode after business hours, so calls in your home office will be automatically forwarded to voicemail. Additionally, the level of toll restriction can be changed on a per extension basis.

Optional Built-in Messaging Card (KX-TA82492)
The KX-TA824 can be equipped with an optional messaging card (KX-TA82492) which adds simple voicemail messaging to the system. This 2-port card will store up to 128 messages, and has a maximum recording time of up to 60 minutes. Each extension has its own personal mailbox, and there is also a common mailbox for general messages. Users can record their own personal greeting, which will be played to callers transferred to their mailbox. When a message is left in a mailbox, the system will notify you by turning on the built-in message-waiting lamp on a Panasonic proprietary telephone. Built in Voice Messaging is an affordable solution perfect for your residence and home office.

Central Office Voice Mail Compatible
The KX-TA824 is compatible with the phone company voice mail service making it very easy to use. The way it works is, phone messages are stored in the voice mailbox at the phone company's central office (CO). Each outside line can be assigned its own CO voice mailbox. When a voice mail message is left on any one of the three outside CO lines, the large message-waiting LED will flash on each system phone and the associated outside CO line button will also flash. By simply pressing the flashing outside CO line button and the "message" button on any extension, the user can access their messages at any time.

Panasonic Voice Mail System Integration
If you require a fully featured Voice Mail system with a built-in auto attendant the KX-TA824 can be connected to our KX-TVA50 voice processing system utilizing Advanced Proprietary Integration. Advanced Proprietary Integration provides the VPS with more information than traditional Integration. This information enables the system to identify the extension number of the caller, know where, from, and why the call is forwarded, and recognize what the caller wants to do. Some features are available only with Advanced Proprietary Integration (Live Call Screening, Two-Way Recording, Two-Way Transfer, Direct Mailbox Access, Intercom Paging, Auto Configuration, Caller Name Announcement [system/personal], Caller ID Call Routing, Personal Greeting for Caller ID).

Caller ID, Call Waiting/Logging¹
With the Caller ID feature, an incoming caller's phone number (or phone number and name if provided by the telephone company) appears on the LCD display of any Panasonic system display telephone. This information is displayed while the telephone is idle or while you're on a call, allowing you to screen calls at a glance. The KX-TA824 even allows incoming calls to be screened from any display telephone in the house. Calls that are not answered can be recalled by accessing either the personal or system-wide Caller ID log.

Single-Line Device Integration
The Panasonic KX-TA824 Advanced Hybrid Telephone System allows you to connect many types of single-line devices such as answering machines, cordless phones, fax machines, computer modems, and even your favorite novelty telephone, without the need for additional cards or modules. Additionally, the system can pass Caller ID information to any Caller ID compatible single-line device.

Backlit Display and Dial Keypad
Easy-to-operate Panasonic KX-T7700 series telephones are perfect for personal and home office use and are designed to match nearly any decor. Their easy-to-see backlit dial keypad makes these phones ideal for use in the bedroom, home theater, or any poorly lit area. Model KX-T7736 includes a 3-line backlit LCD and model KX-T7731 includes a 1-line backlit LCD.

Doorphone and Door/Gate Opener²
Add security to your home with an optional Doorphone and Door Opener Adapter Card. With this option installed, the KX-TA824 can interface with up to four door intercoms (KX-T7775 or KX-T30865) and can control up to four electronic door contact closures. If you have more than one door intercom, you can assign each one a specific ringing pattern3 to help you determine which intercom was pressed. The KX-T7775 Doorphone is equipped with contacts that allow guests to ring a standard doorbell as well. You can also use the adapter cards to control most low voltage devices.

System Speed Dial
This function lets you program up to 100 32-digit frequently called numbers into the system for quick and easy dialing from any system phone. So family members, trusted physicians, favorite restaurants for take-out, the local service station and more will be just a push of a button away.

Toll Restriction
This feature lets you prohibit certain outgoing calls by restricting selected system extensions from accessing specified area codes or exchanges. This can help prevent your children from making long-distance calls. Toll restriction can be changed based on time of day.

Paging and Page Pickup
This feature allows you to make a voice announcement simultaneously to all proprietary phones in the system. Simply page and ask the individual you're trying to reach to pick up the nearest phone. Once that person dials the page pickup code, they'll be connected immediately. Rounding up the troops for work or play has never been easier.

Direct Inward System Access (DISA) with Outgoing Message and Fax Detection³
When several family members share one telephone line, you can make sure callers reach their intended party directly using Direct Inward System Access with Outgoing Message and Fax Detection Card. This option has a built-in 3-Level DISA Auto Attendant, which allows you to program up to three messages that will instruct the caller to dial a single-digit code for the desired party. The caller is then routed to the appropriate extension automatically. DISA also enables you to call into the system from outside your home or office and utilize one of the system's lines to make calls. This feature can be helpful when you need to make calls from a remote location or a cellular phone. Additionally, if a fax call is received (and a CNG tone is detected) during the outgoing message, the call will be automatically routed to the designated fax extension, eliminating the need for a dedicated fax line.

Off-Premises Call Forwarding
This feature comes in handy if you're going to be away from your home or home office and don't want to miss any calls. Simply program the system to forward your calls to an outside telephone number or to your cellular phone and you can answer your calls wherever you go.

Background Music
This feature allows you to connect an appropriate audio source to the system so family members can play music through any proprietary phone in the house with a built- in speakerphone. When the phone rings and the call is answered, the music will temporarily stop. Additionally the music will be played to callers who are placed on system hold.

PC Programming (Remote and On-Site System Administration)
Your Panasonic dealer can program the KX-TA824 Advanced Hybrid Telephone System utilizing a PC. In addition to quicker installation, this method allows the technician to save a database of your specific network parameters for use in getting the system back up and running quickly in the unlikely event that the system should fail. For remote programming the system is equipped with a built-in modem card, allowing your Panasonic dealer to make changes to your system from their office without having to visit your home. So your system can be adjusted remotely, at no inconvenience to you and your family.
