The Delta ASM-24E is a fully programmable, Native BACnet™ Building Controller that communicates on a BACnet MS/TP RS-485 LAN or BACnet over Ethernet. It is an intelligent controller specifically designed for access control applications. This controller provides access control capabilities through a network of door modules which act as extended I/O to the Access System Manager.
The ASM-24E is designed for access control of multiple doors. Up to twelve 2-Door Modules
(ADM -2W704) may be connected to an Access System Manager via LINKnet. The Access System Manager can hold a maximum of 10000 cardholders and events.
The ASM-24E provides easy to configure alarms for system monitoring and annunciation of card-access events and alarms.
Programming the access control system is easy and intuitive because the programming is object oriented. Standard I/O and objects are created automatically and can be modified. GCL+ can be used for advanced custom programming and integration.
—BACnet MS/TP and BACnet PTP protocols
—Database backup via non-volatile Flash memory
—Fully programmable in GCL+
—Application database can be loaded over the network
—Controller firmware can be flash loaded over the network
—Derived Network Addressing (DNA) for simple integration into a standard network architecture
—Operation of the card access system is completely contained in the controller, no PC required for operation
—Can be powered from a 12VDC battery in the event of a power failure
