Security applications 
EST3 Installation and Service Manual  2.17 
Multiple tenant security 
Description of the application 
Figure 2-6 illustrates a simple strip mall security application. The 
mall consists of three identical stores and an electrical room. 
The control panel supports a SIGA data circuit and a SAC bus. 
The panel also supports modem communications via telephone 
lines. 
The SIGA circuit has pull stations and smoke detectors. In 
addition, the SIGA circuit has two security devices, the motion 
detector and the SIGA-SEC2 security loop module. The SIGA-
SEC2 connects a conventional door contact to the SIGA circuit. 
The SAC bus is used exclusively for the KPDISP devices. 
Each company owner has a Keypad Display Configuration 
(KDC) program. The program runs on a computer equipped with 
a modem, and uses the modem and a dial-up telephone line to 
communicate with the control panel. 
Each company owner can use the KDC to download changes to 
that company’s portion of the security database. The changes are 
routed through the panel to the appropriate KPDISP unit. 
Note: Fire and security functionality cannot be programmed into 
a control panel from a remote location. You must perform all 
panel programming on site. Changes to the security database 
have no impact on the parameters or operations of listed fire 
system equipment. 
The control panel can be configured to provide telephone 
connection to a central monitoring station (CMS). Each tenant 
company can have a separate account at the same CMS, or can 
use the services of a separate CMS. 
Refer to Appendix C, “Listing requirements” for additional
