8DBC
This is a combined database unit and door controller for up to eight
readers and associated door furniture (release device, bypass, door
monitor and exit request button).
20mA (MCLP) or Wiegand readers can be connected (Wiegand readers
require the WIM-8 module).
An optional I/O module can be fitted to enable connection of auxiliary
outputs and monitor points.
Additional readers, monitor points and auxiliary outputs can connect using
separate door and/or alarms controllers. The 8DBC can manage up to 16
readers.
2DC
A two-door controller for connection of up to two readers and associated
door furniture. Door controllers can be sited up to 3000ft (1km) from the
database unit.
A port is provided for an optional I/O module, which allows connection of
auxiliary outputs and monitor points.
20mA (MCLP), Wiegand or RS485 readers can be connected (Wiegand
readers require the WIM-2 module; RS485 readers require the Dual
RS485 Reader module).
4DC
A four-door controller, with two ports for optional I/O modules.
20mA (MCLP), Wiegand or RS485 readers can be connected (Wiegand
readers require the WIM-4 module; RS485 readers require the Quad
RS485 Reader module).
4DCN
This is the same as a 4DC, but with the same shape and footprint as a
4DBC. The 4DCN is available only in certain markets.
8DC
An eight-door controller, with one port for an optional I/O module.
20mA (MCLP) or Wiegand readers can be connected (Wiegand readers
require the WIM-8 module).
AC24/4
An alarms controller that provides 24 monitor points and four auxiliary
outputs. The controller can be sited up to 3000ft (1km) from the database
unit.
OC4/24
An alarms controller that provides four monitor points and 24 auxiliary
outputs.
