CRC220-4 ONLINE FOUR DOOR CONTROLLER
CRC220-4
'4 Doors Controlled From a Single Panel'
The CRC220-4 controllers is part of a range of versatile modular on-line access control panels suitable for controlling access points such as doors and vehicle barriers by validating credentials such as cards, key fobs and vehicle tags.
PRODUCT FEATURES & BENEFITS
These controllers are components of an online access control system linked to Norpass3 Access Control Management Software via either TCP/IP or RS485.
The CRC220-4 can be used to control access through up to four doors or barriers with read-in control and free exit, while supporting a wide range of managed access control features and a comprehensive range of interface formats. The enclosure houses 2 two-door interface modules plus an integral power supply unit.
benefits
- Easily managed using simple centralised management of data
- Choice of mix and match module types enables cost-effective network structure
- Support for a wide range of card formats and card reader interfaces makes it the ideal choice for enhancing an existing access control system
- Security levels can be tailored to customer needs using optional security features
- Improved visitor card management when used with our card capture reader
- Meets demanding customer requirements through a choice of enclosures with tamper alarms fitted as standard plus features such as fire alarm control input, individual door alarms and configurable inputs and outputs.

High-Density Door Control for Multi-Entrance Commercial Buildings
The CRC220-4 maximises efficiency in installations requiring read-in access control with free-exit across multiple doors—such as office building corridors, warehouse zones, shopping centre service entrances, or educational facility wings.
By controlling four doors from a single enclosure, installers reduce hardware costs, cabinet space, and wiring complexity compared to individual single-door controllers.
Retail distribution centres commonly deploy CRC220-4 units to manage multiple loading bay pedestrian doors, while corporate campuses use them for floor-by-floor corridor access.
The controller's four independently monitored doors each feature door-held alarms and forced-entry detection, enabling security teams to respond quickly to propped doors or intrusion attempts across busy facilities.

Four Doors
Control four read-in/free-exit doors from a single compact enclosure.
Cost Effective
Reduce per-door hardware costs by consolidating four access points.
Individual Alarms
Each door has independent monitoring with separate alarm outputs.
Fire Integration
Ground-activated fire alarm input releases all four doors simultaneously in emergencies.
The CRC220-4 controls four doors with read-in and push-button/free-exit operation, while the CRC221-2 controls two doors with full read-in/read-out capability. Choose based on whether you need exit credential verification.
The CRC220-4 enclosure houses two CRC220 two-door modules sharing the integral power supply. Each module controls two doors with independent monitoring, relay outputs, and alarm capabilities.
Yes, Norpass3 allows individual access level and time period configuration for each of the four doors, enabling zone-based access policies within a single controller.
The integral 3A 12V PSU provides four individually fused 12V DC outputs capable of powering standard maglocks or electric strikes. These outputs can be fire-alarm linked for emergency release.
Anti-passback operates per controller with configurable reset times. For read-in/free-exit configurations, soft anti-passback prevents sequential same-card presentations at the same reader.
