Access control applications
EST3 Installation and Service Manual 3.17
Hardware configuration
The site has an EST3 control panel that includes a 3-SAC and a
3-MODCOM module. The 3-SAC supports the SAC bus. The
3-MODCOM module supports modem communication with the
control panel over telephone lines.
SDU programming
As the distributor, you use the SDU to program the control panel
for this application. Part of the programming job is to use the
Resource Profile Manager (RPM) to create resource profiles for
the site owner and for each tenant company.
Resource profiles are imported into the Access Control Database
(ACDB) program. They determine which devices the user can
see and program. Resource profiles also establish transmission
routes that permit modem communication with the EST3 panel.
When a device is shared, the RPM lets you specify how much of
the device is allocated to each company. You can allocate
resources either by percentages or by actual numbers.
It’s a good idea to hold some allocation in reserve, giving each
company only what it needs. It is much easier to allocate
additional resources as needed than to reclaim resources that are
already allocated.
In our example, the resource profile for company A would
contain CRC 1 (the lobby door) and CRC 2 (the suite 101 door).
For Company A, you might choose to allocate 80% of CRC 2,
and 20% of CRC 1.
Similarly, the resource profile for company B would allocate
80% of CRC 3 and another 20% of CRC 1.
The site owner will need access to the CRC2 and CRC3 doors
for cleaning or inspection purposes. The site owner resource
profile could allocate 20% of CRC 1, 10 % of CRC 2, and 10%
of CRC 3.
This leaves 40% of CRC 1 unallocated, and 10% of CRC 2 and
CRC 3 unallocated. The unallocated resources are reserved for
future expansion or changes.
ACDB operation
The site owner, the owner of company A, and the owner of
company B, can all use telephone lines to communicate with the
control panel via the 3-MODCOM module. They can download
additions and changes to the CRCs, and upload usage data for
various ACDB reports.
