<strong>ACS3000</strong>/<strong>ACS4000</strong><br />
<strong>Control</strong> <strong>Panel</strong> <strong>Wiring</strong><br />
Overview: This application note explains proper wiring of <strong>Brivo</strong> control panel door<br />
latch relay circuits.<br />
Applicability: All <strong>Brivo</strong> <strong>ACS3000</strong> and <strong>ACS4000</strong> series control panels.<br />
Introduction<br />
The <strong>Brivo</strong> Door <strong>Control</strong> Boards were designed to have each door latch relay circuit<br />
individually wired to the door latch that it controls and the power supply for those<br />
circuits.<br />
While it is a common practice to daisy-chain the common terminals of the latch<br />
relays to one another, this wiring configuration can result in unstable operation of<br />
the relays and latches (commonly know as “chattering”).<br />
To avoid this potential side-effect of the daisy-chain wiring technique, please observe<br />
the correct wiring technique illustrated in the picture below. (The Incorrect wiring is<br />
also shown on the following page.)<br />
