ACUXL16 

Overview
The ACUXL16 Networked Intelligent Controller features state-of-
the-art technology, and provides both the flexibility and reliability 
needed to meet today’s complex access control and alarm monitor-
ing requirements. Using a sophisticated, high speed embedded 32-
bit, 90 MHz microprocessor and high-capacity 16 MB memory, the 
ACUXL16 controls up to 16 readers. Each ACUXL16 supports large 
card populations of up to 250,000 and has the ability to communi-
cate over LAN, fiber, dial-up or RS-485 networks. 

The ACUXL16 interfaces with all GE Security Diamond II and Sap-
phire Pro servers, and offers the widest range of features and 
flexibility, with a design focus on reliability, durability, and ease of 
installation and maintenance. 

The ACUXL16 panel incorporates two external device ports, each 
capable of controlling eight readers/interfaces, which are multi-
dropped using an RS-485 interface. Input and output capacity can 
be expanded — see the ACU Remote Modules datasheet for details. 
Each panel includes a parallel printer port to provide local, real-time 
printing of transactions. 

Standard Features

Supports up to 16 readers and associated interfaces through 
two RS-485 communication ports. 

Supports magnetic stripe, Wiegand, barium ferrite, barcode, 
proximity, biometric and smart card technologies. Each reader 
is user-configurable (card only, card & keypad, or keypad only). 
Variable card formats, multiple site codes and company codes 
are supported. 

Alarm Monitoring: The ACUXL16 includes 12 fully supervised six-
state alarm inputs which provide false alarm filtering and utilize 
digital signal processing. Any combination of up to eight remote 
interface modules can be connected in place of reader inter-
faces for additional capacity, including Relay Output Modules 
(described below), and Alarm Input Modules (RIM) which provide 
16 additional six-state supervised alarm inputs with tri-color LED 
status indicators (each). 

Each alarm input allows detection/reporting of circuit trouble 
conditions: loop resistance too low (short circuit), loop resistance 
too high (open circuit), loop voltage out of range (circuit fault), 
and a portion of loop grounded (ground fault). 

The ACUXL16 includes 12 SPDT relay outputs that are configu-
rable for control of locking devices, activation of local annuncia-
tors and other output applications. Each SPDT relay is rated at 
2.0 A, 30 VDC, and includes an LED status indicator. Any combi-
nation of up to eight remote interface modules can be connect-
ed in place of reader interfaces for additional capacity, includ-
ing Alarm Input Modules (described above), and Relay Output 
Modules (RRM) which provide 16 additional output relays (each).
