Description
The BRA from Alpha is a digital dial controller board used with our BRK16 16- station relay card(s), DB1 series LCD display(s), and EMDB1 (or EMVDB1) series keypad module(s) to provide digital dialing capabilities to a variety of intercom or video-intercom systems. Up to 239 apartment intercom and/or video-intercom stations can be signaled by using the BRA in conjunction with up to 15 BRK16 units. Each BRK16 used with the BRA controller provides up to 16 time-delayed dry contact (normally open) relay closures to activate the apt. station’s call signal. This makes the BRA and BRK16 combination a nearly universal digital dialing solution. The BRA multi-entrance adapters are designed to easily surface mount right onto the finished wall by means of customer supplied screws or the convenient plastic ‘Din Rail’ bracket supplied with each power supply. Connections are positive screw terminal type.
