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.
