Preparation

Reader Location: Select the reader's mounting location. The XK-3640 Reader may be screwed to a single-
gang utility box like a cover plate, or to a wall or other surface. On a metal surface, read range is reduced about
20%. The XK-3640 Reader may be installed indoors or outdoors, but needs protection from direct rain or snow.
DC Power Supply: DC power for this reader is usually supplied from the +DC and Ground terminals of the
Wiegand reader port on the system's panel. If this is not possible, use an independent power supply. Power
may be shared with other readers if the supply has sufficient current capacity. The power supply should be
nominal +12 volts DC (as low as +5 volts is OK); 1 ampere capacity; linear-rated; regulated DC output.
Cable to Controller and Power Supply: 4 conductors from reader to the system (2 wires for DC power, and 2
wires for Wiegand data). 22 gauge. Overall 100% shield for both power and data. 500 feet maximum length.
If the DC power supply is independent from the panel's reader port, the reader's Black wire must be
connected to both the DC power supply's Negative terminal and the panel's Ground terminal.
If the DC power supply is close to the reader, run two 22 gauge cables – 2 wires for DC power, and 3 wires
for Wiegand data. Both cables must be overall-shielded and earth-grounded.
Conduit: If cables are pulled through metal conduit, the conduit should be earth-grounded (like the cables).

Programming

The XK-3640 reader is shipped with the keypad's output set for buffered 26-bit output, and its facility (site)
code set at 000. These two features can be programmed at your shop before you go to the installation site. Just
connect DC power from a bench supply or from a 9 volt or 12 volt battery to the red and black wires.
Start either programming routine with DC removed from the XK-3640 unit. Keep the unit fully assembled.
Keypad's Output Format
1. While the DC power is disconnected . . . press and hold the 4 key if format is to be 4-bit data burst;
or hold the 8 key for 8-bit data burst, or hold the 2 key for 26-bit buffered data.
2. With the 4 or 8 or 2 key still pressed in, connect the DC power. Within 3 seconds there is a beep
sequence, and the LED changes to standby-red.
3. Now release the pressed key. The change in keypad output format has been saved.
Facility Code in Keypad's 26-bit Buffered Output
1. Connect the DC power. Watch the unit's LED. While it is amber, slowly enter the 10-digit password
9 1 4 3 6 9 8 8 0 0; end with #. Press each key solidly. There is a short beep during each keystroke.
2. Within 3 seconds, enter the facility code's 3 digits (between 000 and 255); end with #.
3. There is a long beep and the LED color changes to standby-red. The facility code has been saved.
Programming can be done also on an installed XK-3640. The keypad's format can be changed anytime to any
of the three formats, and the 26-bit's facility code can be changed to any value between decimal 000 and 255.
Programming for Operation Mode (mix of card read and/or PIN) is done only in the host system's software.
