ACCESS CONTROL SYSTEMS FOR DOORS

Door access control systems regulate entry to individual doors, rooms and restricted areas by checking an authorised credential before releasing an electronic lock. Unlike a conventional key system, electronic access control allows organisations to define who can enter, which doors they can use and, where supported, when access is permitted.

Solutions can be deployed for a single entrance or expanded across multiple doors, floors and locations. Common credentials include RFID/proximity cards, PINs, mobile credentials and biometrics such as fingerprint or facial recognition.

How Door Access Control Works

A typical installation consists of:

Access reader or authentication terminal
Door controller or access control panel
Electronic lock such as a magnetic lock or electric strike
Exit button or No-Touch request-to-exit device
Door contact/sensor
Power supply and, where required, backup power
Management software or web-based platform

When a user presents an authorised credential, the reader communicates with the controller. The controller checks the access permission and releases the lock when the credential is authorised. Depending on the system, access events can be recorded for reporting and administration.

Modern platforms may support TCP/IP, RS-485/OSDP, Wiegand, Wi-Fi or other communication methods, depending on the selected equipment.

Door Access Control Options

The appropriate configuration depends on the security requirements, door type and operating environment.

RFID and proximity cards are practical where many employees require straightforward credentials.

PIN/keypad systems allow users to authenticate using a code and can be suitable for selected restricted areas.

Biometric readers can use fingerprint, facial or other supported biometric credentials where individual authentication is required.

Mobile credentials can allow compatible smartphones or other devices to be used as credentials.

Multi-factor access combines two or more authentication methods for areas requiring additional verification.

Door access control is commonly considered for:

Corporate offices and executive areas
Server and communications rooms
Banks and financial institutions
Schools and universities
Hospitals and healthcare facilities
Apartments and residential estates
Warehouses and factories
Hotels and commercial buildings
Government and institutional premises
Laboratories and restricted work areas

For larger facilities, multiple doors can be connected to central management, allowing administrators to manage users and permissions across defined areas.

Professional Installation and System Design

Effective access control starts with the door, not simply the reader.

Before installation, Solutions Unlimited assesses the door construction, frame, existing lock, direction of opening, traffic pattern, power availability, network requirements and the level of security required.

The installation may involve mounting the reader, fitting the appropriate electronic lock, connecting the controller and power supply, installing exit devices and door contacts, configuring users and permissions, and testing the complete entry and exit sequence.

The correct lock also matters. A magnetic lock, electric strike or other locking arrangement should be selected according to the door and operational requirements rather than using one lock type for every installation.

Where access control is being added to an existing building, cable routing, power protection and the physical condition of the door should also be considered.

Emergency Exit and Fail-Safe Considerations

Access control must never compromise safe evacuation.

Kenya’s Occupational Safety and Health Act requires adequate means of escape and requires escape routes to be maintained free from obstruction. It also contains specific requirements concerning workplace exit doors.

Accordingly, doors forming part of an emergency escape route should be designed with the appropriate exit hardware, emergency release and fail-safe arrangements for the particular installation and applicable building requirements.

Integration and Accessories

Depending on the system, door access control can be integrated with:

Biometric time attendance
Intercom and visitor management
Turnstiles
Elevator access
Alarm systems
Door monitoring
Centralised management software

Common accessories include emergency door-release units, No-Touch exit switches, exit buttons, door sensors, power supplies, RFID cards and slave readers.

Maintenance, Replacement and Support

Access control equipment contains both electronic and mechanical components. Regular inspection can identify worn locks, damaged readers, loose connections, depleted backup batteries and door alignment problems before they affect normal operation.

Credentials can also require replacement when cards are lost, damaged or no longer assigned to an employee. Organisations operating larger systems may benefit from maintaining spare cards, compatible power supplies and selected replacement components.

Solutions Unlimited supplies and installs electronic access control systems and provides technical support for the systems supplied. Depending on the product, applicable warranty terms can provide up to two years manufacturer’s warranty and ongoing technical assistance.

Frequently Asked Questions

How much does a door access control system cost in Kenya?

Cost depends on the number of doors, reader type, lock, controller, cabling, software, integration requirements and installation conditions. A site assessment or specification review is recommended before quotation.

Can access control be installed on an existing door?

Yes. Many existing doors can be converted to electronic access control, subject to the door, frame, lock type and available power.

What happens if there is a power failure?

The response depends on the lock, power supply and system design. Backup power and appropriate fail-safe or fail-secure arrangements can be incorporated where required.

Can one system control several doors?

Yes. Multi-door systems can use central controllers and management software to administer users and permissions across multiple entry points.

Can access control work with time attendance?

Yes. Compatible systems can integrate access credentials with time-attendance platforms, although the exact integration depends on the hardware and software selected.

Does access control replace a security guard?

Not necessarily. Electronic access control automates credential verification and records access activity, but it can complement rather than replace physical security personnel and other security measures.
