AC-1

The AC-1, Continuum’s access control module, provides full I/O for an access controlled door or portal in one compact module. The AC-1 can be located near an access controlled door for localized control and reduced wiring costs; or several AC-1 modules can be grouped together and DIN rail-mounted for centralized control.
The AC-1 provides a Wiegand card input for Wiegand swipe and proximity type cards, reading up to 64 bits per card. Reader power is 50 mA at 5V. The module itself can be powered by a voltage source that can range from 10-28 VDC. The AC-1 has two 5 A, Form C relays—one for the door lock and a second for local alarm annunciation. Each output has an integral hand-off-auto switch for manual operation, and software feedback of the switch position. Up to three supervised alarm inputs can be used for door status contacts, request-to-exit devices, a cabinet tamper switch, or any other two-state or three-state (on/off/trouble) alarm device.

KEYPAD CONTROL
The AC-1 supports Wiegand output keypads. To simplify installation and reduce wiring costs, a combination Wiegand output reader/keypad may be used. In this case, the keypad data comes into the module via the reader data lines. In addition, the AC-1 allows separate wiring of both a Wiegand output keypad and reader.

ACCESS CONTROL
During normal operation of the AC-1, access decisions are made in the ContinuumNetController CPU , which provides storage for up to 75,000 “local” personnel records. In addition, the NetController’s event buffer is software-configurable to allow for the most optimized memory usage. If network communications are interrupted, the AC-1 will revert to a programmable degrade mode of operation, providing uninterrupted card access using site codes and other degrade mode parameters stored in non-volatile

EEPROM in each AC-1 module.
A door can be configured to operate based on site code only, site code plus card, card plus personal ID number (PIN), or keypad only. The door’s operating mode can even be changed based on time-of-day or other events for optimum flexibility through Andover Controls’ easy-to-use Plain English® programming language. Each keypad can also permit entry of a duress alarm code that can initiate an alarm sequence at any AC-1 controller or at the Continuumworkstation. Time-based anti-passback and entry/egress anti-passback are available to prevent tailgating. Entry/egress anti-passback is system-wide and can be performed by readers located on different AC-1 controllers across the network. Using Plain English, the AC-1 can also be used for custom access control sequences such as two-man rule, optical turnstile control, and man trap configurations.



AC-1 Plus

The AC-1 Plus, Continuum’s full-feature access control module, provides full I/O for an access controlled door or portal in one compact module. The AC-1 Plus supports multiple card formats, ADA (Alternate Door Access) doors, and multiple reader LED patterns. In addition, built-in reader supervision is provided—one LED will periodically check for voltage, absence of voltage, or shorts, and expose any of these conditions to the user for security purposes.The AC-1 Plus can be located near an access controlled door for localized control and reduced wiring costs; or several AC-1 Plus modules can be grouped together and DIN railmounted for centralized control.
The AC-1 Plus provides a Wiegand card input for Wiegand swipe and proximity type cards, reading up to 64 bits per card. The AC-1 Plus also supports CardKey cards, reading up to 34 bits per card, and ABA card readers. Card reader power is 50 mA at 5V . The AC-1 Plus has two 5 A, Form C relays—one for the door lock and an auxiliary output for local alarm annunciation, for example. Each output has an integral hand-off-auto switch and software feedback of the switch position. The AC-1 Plus provides five supervised input channels, configurable as an exit request, door switch sensor, ADA exit request, bond sensor, or as a general purpose supervised input point.

If network communications are interrupted, the AC-1 Plus will revert to a programmable degrade mode of operation, providing uninterrupted card access using site codes, card formats, and other degrade mode parameters stored in non-volatile EEPROM such as multiple card types (including custom format) and four site codes per each card type. ADA doors are also supported in degrade mode. A door can be configured to operate based on site code only, site code plus card, card only, card plus personal ID number (PIN), or keypad only. The door’s operating mode can even be changed based on time-of-day or other events for optimum flexibility through Andover Controls’ easy-to-use Plain English® programming language.
