I just placed an order with EmpiretecAndy which included Dahua's DB-11 DoorBell. I am asking the forum for comments on power specifications. (Will separately post install project). My current doorbell is wired with a cat5e from a simple doorbell button outside to my 1832 PowerSeries alarm board in the basement. When the doorbell is pressed (circuit is normally open, so when pressed, is closed), a chime sounds throughout the house on the alarm system. This was accomplished by wiring the doorbell with a single wire pair from the cat5e into a single zone of the DSC alarm system. I programmed the zone definition as a 24 hour non-alarm, changed the zone attributes so the upon fault and restore (opening and closing of the circuit via press and release of the doorbell button), a chime sounds. Then I changed the chime to differentiate it from the chime sound of a door opening and closing. Viola - Doorbell through your house alarm! It will be very difficult to pull a 2-wire to the doorbell location. I also don't have a chime, and am doubtful that the wireless chime will sound as loud and permeate the house like the alarm chime does. So my idea is to modify the DB-11 and use power from the DSC alarm to power the DB-11 over the remaining cat5e pairs. First, I ask this forum to determine whether the power out from the DSC is sufficient to run the DB-11. Next I'll ask if the modification to the DB-11 to continue to use the DSC ram as my "chime" will work. Power spec from the DSC manual are attached. I have the PC1832 series. A pic of the power side of the PC1832 Board is also attached indicating a 16V AC/2.5A max. power input. I was thinking of jumping onto this power supply to supply DB-11. Will this work? Power requirements for the db-11 are attached. To keep using the DSC alarm as my "chime" I want to modify DB-11. A tear down of the DB-11 can be found here DHI-DB11 Doorbell Teardown Internal Photos 1 Zhejiang Dahua Vision Technology Co., Ltd I want to solder jumper wires from the push button lower pins (K1?) in the middle of the attached picture. The thought is that this is the location that open/closes the circuit. However, I'm concerned that there may be current running through that button and "mess something up?" Thoughts welcome.
