Description
The ADM-2W704 is an intelligent device used for access control of two single-direction doors, or one bi-directional door. When connected to an Access System Manager (ASM) on the Delta LINKnet network, it provides remote, fully programmable, door access control and expanded I/O capabilities.

Application
The ADM-2W704 is designed for access control of 2 single direction doors or 1 bi-directional door. Up to twelve door modules may be connected to an Access System Manager (ASM-24E) via LINKnet.

The ADM-2W704 is equipped with a built-in battery charging circuit to provide optional battery backup for the Controller, all of its peripheral equipment (i.e. Card Readers, Door strikes, and Maglocks) and the Access System Manager when the AC power fails.

All external inputs can be monitored for wiring status using EOL devices (Types 1, 2, 3, 4), which give trouble indication as well as normal and alarm conditions. 

Features
—Controls two single-direction doors or one

bi-directional door

—2 Weigand input ports per board

—Can operate under a degraded mode of operation in the event of communication failures

—Communicates on LINKnet

—Configurable Wiegand card format up to 64 bits

—All external inputs can be monitored to give status of the input wiring using EOL devices (Types 1, 2, 3, 4)

—Easy-to-mount housing

—Designed for easy field wiring

—Equipped with battery charging circuit
