Andover Controls DI-8 - AC-1 Access Control Module

Continuum I/O System Reference 113
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 remotely located at a door
reader 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 and Proximity type cards, reading
up to 64 bits per card. An AC-1-ABA model is also available to support the ABA card
reader protocol and magnetic stripe cards. Reader power on both models is switch-
selectable between 5 volts and 12 volts to meet most card reader power requirements.
Both models have two 5 amp, 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, and any other two-state or three-state (on/off/trouble)
alarm device.
Keypad Control
The AC-1 and AC-1-ABA support Wiegand output keypads and ABA output keypads
respectively. To simplify installation and reducing wiring costs, the keypad data comes
into the module via the reader data lines.
