EXcel4 Controller


EXcel4 provides the building blocks for mid to large-size, single or multi-site networked access control system networks. These versatile access controllers serve two or four readers and provide a highly cost-effective solution for access control
and integrated security system requirements.

It features supervised inputs and relays, making it suitable for monitoring and signaling alarm conditions as well as integration with intruder alarms and building management systems. It also has an in-built TCP/IP port as standard to allow connection to modern IT networks, simplifying installation and commissioning.
