Precision Framing

Solid building doesn't need to gradual you down. actually, making an investment a bit additional time through the early levels of building will truly prevent time and cash later. That's the assumption in the back of Precision Framing, the recent ebook by means of Mike Guertin and Rick Arnold. The authors have spent two decades constructing their field-tested framing ideas, and Precision Framing is the end result -- a "manual" jam-packed with information, recommendation, and shortcuts.

1. Install the resistors first. 2. Install the LEDs, making sure that the polarity is correct. 3. Install the transistors, again checking for correct installation. [ 45 ] Building the Hardware 4. Install the ICs preferably on sockets to make repairs easier. 5. Finally, install the connectors. Opto-isolated output PCB schematic All four circuits are identical. 3V to the base of the NPN transistor. This turns on the transistor and pulls the collector of the transistor low. This turns on the status LED [D1 – D4] and the LED portion of the 4N35 optoisolator.

Keep the wires as short as possible so that they can be tucked neatly into the case of the contacts. EOL resistor inside a door contact (bottom view) Here, we see the end of line resistor neatly stowed into the case of the window contact. Assembled window contact (top view) The idea is that once the contacts are mounted onto the door or window frame, the contacts with the EOL resistor will look exactly like all of the other contacts and the burglar will have no idea which set of contacts contains the end of line resistor.

The 5V power comes from P9 pin 5 and the ground is P9 pin 1. As I said before, all that the alarm system does is monitor contacts and take the appropriate action. The system doesn't know or care what is ''behind'' the contacts. To make it easier for the reader to understand, I have labelled the switches—Alarm In to simulate door or window contacts, and Alarm Reset to simulate the alarm reset button or the switch. In the following diagram, the BeagleBone connector number and pin numbers are indicated by the flags attached to the circuit drawing.
