BRA Controller Board for Digital-Dial System
The Alpha Communicat ions® / S.T.R.™ BRA digital dial controller boards are used with our BRK16 16- stat ion relay card(s), DB1 series LCD display(s), and EMDB1 (or

intercom or video-intercom systems.
Up to 239 apartment intercom and/or video-intercom stations c an be signaled by using the BRA in conjunction with up t o 15 BRK16 units.
Each BRK16 used with t he BRA c ontroller provides up t o 16 time-delayed dry c ontac t (normally open) relay c losures to act ivate the apt . st ation'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 t he finished wall by means of cust omer supplied screws or the c onvenient plastic 'Din Rail' brac ket supplied with eac h power supply. Connect ions are positive sc rew terminal type.
