Access control applications
3.34 EST3 Installation and Service Manual
Hardware configuration
The control panel must contain the following rail modules:
• 3-SAC Security Access Control module
• 3-PPS/M Primary Power Supply module
• 3-MODCOM Modem Communication module
—or—
3-RS232 Card option installed in the CPU
The 3-SAC module supports the SAC bus. Power for the CRC is
normally taken from the 3-PPS/M and is routed with the data
lines in a cable composed of two twisted-pair wires.
The 3-MODCOM module supports modem communication
between the control panel and the ACDB program via telephone
lines. Alternately, the 3-RS232 Card supports RS-232
communications on a cable connected directly to the CPU.
All CRCs controlled by a muster station must be on the same
3-SAC card as the muster station. Badging out at a muster station
badges the person out of all partitions for that 3-SAC card.
Therefore, a single muster station can serve multiple partitions,
provided that they are on the same 3-SAC card.
The system must have at least one muster CRC per 3-SAC
module. The system cannot exchange muster information
between 3-SAC modules, so each must be handled separately for
muster purposes.
A CRC used for a muster station requires the specified dummy
load on the lock terminals to maintain supervision. (Refer to the
CRC installation sheet for correct resistor values.)
The card reader used for the muster station must be wired as an
outside reader.
SDU programming
Each CRC used in a muster application requires specific
configuration settings. These are made in the SDU program, on
the CRC Configuration tab.
If the CRC is used in a partition that has muster control, check
the Muster Support box.
For the CRC designated as the muster station, check the Muster
Station box, but leave the Muster Support box clear.
In the SDU, you can also assign a predefined command list to
the Access Granted Muster event.
