[Asterisk-Users] External relay triggered by Asterisk extension - question
Has anyone every setup an external open/close relay, off say a serial interface, and have an extension trigger the relay? Why I ask is I have a student accomodation where I am installing an asterisk box to supply phone services to the tenants, there is already an intercom system in the main hallways that triggers the downstairs door and gate using a standard relay open/close trip, so I was hoping to get the linux box with asterisk to trip the same type of relay. Is there any door phones that are speaker driven only and sip based that anyone knows about as well? James

Done something similar in a different application, but * should handle it -- In my case, I took a crystalfontz LCD, type 633, and used two of the four fan-outputs to drive two 12V relays. As a nice extra, you get temperature capabilities thrown in, so you can monitor your set-up. The LCD runs on serial, of course. As an alternative, you can use any of the many available relay boards -- $50 gets you this: http://www.phanderson.com/iom141.html> -----Original Message----- > From: James Bean [mailto:james@hdcs.com.au] > Sent: Saturday, February 19, 2005 11:34 PM > To: Asterisk Users Mailing List - Non-Commercial Discussion > Subject: [Asterisk-Users] External relay triggered by > Asterisk extension -question > > > > Has anyone every setup an external open/close relay, off say > a serial interface, and have an extension trigger the relay? > > Why I ask is I have a student accomodation where I am > installing an asterisk box to supply phone services to the > tenants, there is already an intercom system in the main > hallways that triggers the downstairs door and gate using a > standard relay open/close trip, so I was hoping to get the > linux box with asterisk to trip the same type of relay. > > Is there any door phones that are speaker driven only and sip > based that anyone knows about as well? > > James > > _______________________________________________ > Asterisk-Users mailing list > Asterisk-Users@lists.digium.com > http://lists.digium.com/mailman/listinfo/aster> isk-users > To > UNSUBSCRIBE or update options visit: >http://lists.digium.com/mailman/listinfo/asterisk-users
