DC22
Door controller with alarm control functions
The DC22 is designed to monitor and control one door in a SiPass Entro
or SiPass integrated system. When BC-Link is used‚ a single DC22 can
support two readers and thereby control both entries and exits to a
restricted area (anti-passback).
The DC22 includes an integrated status display window to simplify
installation and service. It is compatible both with SiPass readers and
with most third-party readers that support Wiegand and Clock&Data
standards.
The major difference between the DC12 and the DC22 is that the DC22
has additional inputs/outputs that support advanced alarm control
functions‚ e.g. alarm status feedback (ASF). These are essential when
integration with an intrusion detection system is required. The DC22
also has two outputs for electric locks (day/night lock) as well as sepa-
rate inputs for open/closed and unlocked/locked door.
Note: The intrusion and ASF functions of the DC22 are only available in
SiPass Entro.
