Figure 10-4: Modifying ACIU for Operation with Dorado 7401 or 7901 Card Reader
Using the Operating Panel for Access Control
Access can be controlled not only by card/key readers, but also by the FOCUS operating panel. The
person requesting access must enter a valid 6-digit code to gain entry. Either of three methods can be
used:
•
Using an ACIU to control power to a 12-volt door strike.
The control unit commands the ACIU to have its on-board battery provide the 12V potential for
releasing the door strike when a valid code is entered at the operating panel. No connection is
required between the operating panel and the ACIU. The only ACIU connections that are needed
are to the RS-485 bus and to the door strike. The operating panel is linked to the ACIU through
programming.
•
Sharing an ACIU with a card/key reader.
An operating panel is linked to the same ACIU as a card/key reader, so that either the card/key
reader or the operating panel can be used for access control. In this arrangement, a person who
forgot his card can use the operating panel to gain access. Note that the operating panel can only
be installed indoors.
•
Using a BA Access output point to control the power to the strike.
The control unit commands the BA Access output point to turn on when a valid code is entered at
the operating panel. When turned on, the BA Access output point closes the circuit to a separate
power source, thereby applying power to the door strike.
Installing the Operating Panel for Use With Access Control
If an operating panel is being used for access control, it must be assigned to communication Group 0.
Install the operating panel in the usual manner.
Where an operating panel is being used for access control with an ACIU, its communication Unit number on
the RS-485 bus must coincide with the communication Unit number of the ACIU. An operating panel being
used for access control (Communication Group 0) becomes locked out during the period that any other
operating panel at communication Group 0 becomes activated, and vice versa.
