Bell System CS106-4 4-Way Coded Door Entry Kit Surface

Combined 4-Way Audio Door Entry & Coded Access System with Surface Lock Release

The Bell System CS106-4 4-Way Coded Door Entry Kit combines a conventional audio door entry system with standalone keypad-controlled access, providing a practical entrance security solution for buildings requiring communication with four separate users or internal telephone positions.

Designed as the 4-way version of the Bell System CS106 series, the system allows visitors to call the required property or user from the external entrance panel. Occupants can communicate with visitors using the supplied Bell System 801 telephones before operating the electric lock release to grant entry.

For residents, staff and other authorised users, the integral C106 coded access keypad provides convenient keyless entry. Up to 10 unique access codes can be programmed into the keypad, and entering a valid code operates the lock release for a preset duration.

Clear green and red LED indicators provide immediate feedback at the entrance. The green LED indicates that the lock release is operating, while the red LED identifies an invalid code entry.

Supplied with four Bell 801 telephones, a CP106-series aluminium entrance panel with keypad, model 61 speech unit, PS4A 12V 4A DC power supply and model 203 surface lock release, the CS106-4 provides the principal components required for a professional four-way coded door-entry installation.

4-Way Door Entry System

The CS106-4 is configured as a four-way door-entry system, making it suitable for a common entrance serving four separate users, properties or internal telephone positions.

Visitors use the external entrance panel to select the appropriate call position. The corresponding occupant can then communicate with the caller using their internal Bell 801 handset.

This makes the CS106-4 particularly useful for four-flat conversions, small apartment buildings, shared residential entrances and suitable commercial premises.

Combined Door Entry & Coded Access

The CS106-4 combines two useful entrance-control functions within one system.

For visitors, it operates as an audio door-entry system, allowing communication with the occupant before entry is granted.

For regular authorised users, the integrated keypad provides direct coded entry without requiring them to call one of the internal telephones.

This combination makes the system convenient for properties where both visitor communication and keyless access are required at the same entrance.

Four Bell System 801 Telephones

The CS106-4 configuration uses four Bell System model 801 door-entry telephones.

Each handset provides an internal communication point, enabling the respective occupant to speak with visitors at the entrance.

Once the visitor has been identified, the occupant can operate the door-release facility from inside the property.

With four internal handsets, the system is ideally configured for a building containing four individual flats, offices or other separate users.

Aluminium Entrance Panel with Coded Keypad

The system includes a CP106-series aluminium entrance panel incorporating the coded keypad module.

Integrating the visitor call facilities and keypad into the same entrance panel provides a neat, professional appearance and avoids the need for a completely separate access-control keypad.

The aluminium construction also makes the panel well suited to professional residential and commercial door-entry installations.

Up to 10 Unique Access Codes

The C106 keypad can be programmed with up to 10 unique user access codes.

This provides greater flexibility than simply allocating one code to each of the four internal users.

Additional codes can be provided to other authorised users where appropriate, such as building managers, maintenance personnel or regular authorised visitors.

Keyless Entry for Authorised Users

Regular building users can enter using their programmed code rather than relying solely on a physical key.

When a valid code is entered, the system activates the electric lock release for the programmed period.

This provides a straightforward and convenient keyless entry solution for residents, employees and other approved users.

Programmable Lock Release Duration

The C106 keypad allows the lock-release operating duration to be preset.

Following successful entry of an authorised code, the release operates for the configured period, allowing the user sufficient time to open the door.

This provides greater control than a permanently released arrangement and allows operation to be tailored to the entrance.

Red & Green LED Status Indication

The keypad incorporates red and green LED indicators to provide clear visual feedback.

The green LED indicates that the lock release is operating, confirming that a valid code has been accepted.

The red LED indicates an invalid entry, providing immediate feedback when an incorrect code is entered.

Bell System Model 61 Speech Unit

A Bell System model 61 speech unit forms part of the audio door-entry arrangement.

The speech unit enables voice communication between the external entrance panel and the internal 801 telephones, allowing occupants to establish who is calling before deciding whether to grant access.

PS4A 12V 4A DC Power Supply

The system incorporates a Bell System PS4A 12V 4A DC power supply.

This provides the low-voltage power required by the compatible components within the door-entry and access-control system.

Bell 203 Surface Lock Release

The CS106-4 is supplied with a Bell System model 203 surface lock release.

This electrically operated release allows the entrance door to be unlocked when access is granted from an internal telephone or following successful entry of an authorised keypad code.

The inclusion of a surface lock release makes this particular kit suitable for entrances where this type of locking arrangement is appropriate.

Controlled Visitor Access

Visitors use the entrance panel to call the relevant occupant.

The occupant can then communicate with the visitor using their Bell 801 telephone before deciding whether the door should be released.

This provides a simple method of controlling visitor entry without requiring an occupant to physically attend the entrance.

Convenient Access for Residents & Staff

Authorised building users can bypass the visitor calling process by entering their access code directly at the keypad.

This is particularly convenient for a shared entrance serving several residents or employees.

With up to 10 user codes available, the system can accommodate more authorised users than the four internal call positions alone.

Standalone Coded Access System

The coded-access section is designed as a standalone system, providing straightforward local access control without requiring a larger networked security platform.

Bell System describes the CS106 series as appropriate where a basic level of security is deemed adequate.

This makes it particularly suitable for residential properties and smaller commercial installations requiring convenient visitor and coded access rather than a sophisticated centrally managed access-control system.

Ideal for Four-Flat Conversions

The four-way configuration makes the CS106-4 especially useful for a building converted into four separate flats.

Each property can have its own internal Bell 801 telephone connected to the common entrance system.

Visitors can call the appropriate flat, while residents can use the coded keypad for convenient access through the shared entrance.

Suitable for Small Apartment Buildings

The system is also well suited to purpose-built or converted apartment buildings with four internal users.

Its combination of individual calling, speech communication and shared coded entry provides the principal functions required from a straightforward communal entrance system.

Suitable for Commercial Applications

The CS106-4 is not restricted to residential use.

It can also be used in appropriate commercial properties where a common entrance serves four separate offices, departments or users.

Staff can use keypad codes for regular access while visitors can contact the appropriate internal position using the door-entry panel.

Complete 4-Way Door Entry Kit

The CS106-4 brings together the principal components required for a four-way installation, simplifying product selection for electricians and security installers.

Why Choose the Bell System CS106-4?

The Bell System CS106-4 provides a practical combined solution for entrances serving four separate users or internal call positions.

Visitors can call the appropriate occupant and communicate through the audio door-entry system before access is granted. Meanwhile, residents, staff and other authorised users can enter directly using the integral coded keypad.

The keypad supports up to 10 unique access codes, providing flexibility for a range of authorised users beyond the four principal occupants. A programmable lock-release duration and clear red and green status LEDs make everyday keypad operation straightforward.

Four Bell System 801 telephones provide the internal communication points, while the model 61 speech unit handles the audio communication at the entrance. The supplied PS4A 12V 4A DC power supply supports the system, and the included 203 surface lock release provides electrically controlled door opening.

For four-flat conversions, small apartment buildings, shared residential entrances and suitable commercial premises, the Bell System CS106-4 offers a straightforward combination of four-way visitor communication and coded keyless entry.
