SECURITRON MODEL DK-16W DIGITAL KEYPAD

INSTALLATION & OPERATING INSTRUCTIONS

1. DESCRIPTION
Securitron's DK-16W is a two piece digital keypad system designed to output Weigand 2601

format data and therefore integrate into an access control system just as if it was a card

reader. It consists of two components: the keypad and the CPU board. The keypad is for indoor
use only and installs in a single gang cut-out. It includes two active LED’s (green and red
controlled by the system) and a beeper.

2. PHYSICAL INSTALLATION
Two wallboxes are supplied with the DK-16W pad. The backless wallbox is used for flush

mounting on dry wall or other material where a cut-out can be made. The two-piece wallbox
allows surface mounting on a variety of materials. To use the two piece wallbox, note that its
cover and base are snapped together and must first be separated by either pulling the outer rim
of the cover away from the base or inserting a screwdriver into the four holes at the corners of
the cover and prying the base loose. Once the base is separated from the cover, remove the
large rectangular knockout in the center of the base by cutting around it with a knife and then
popping it out. The base can then be mounted with the supplied #6 sheet metal screws and
plastic anchors. The DK-16W pad mounts on the cover with the supplied #6 machine screws
(tamper or standard are supplied) and the assembly then snaps into the mounted base. Wires
are usually pulled through the center of the base although it is also possible to attach plastic
wiremold raceway to the side of the cover (note the knockouts on the inside of the cover sides).
Raceway is not recommended because it’s quite easy for anyone to attack the wires.

The DK-16W pad can be used outdoors with the optional rain cover (part #WCC) although we do
not advise this use in areas exposed to heavy, direct rain. When used outdoors, you must
supply a weatherproof, gasketed wallbox (available from Securitron under part #WBB).

The CPU Board is furnished in a snap-apart steel enclosure with the board itself mounted on
plastic snap-trak. The CPU Board must be installed in a dry location free of extremes of
temperature and humidity. If the 16 ft., twelve conductor cable that is included is not of
sufficient length, additional cabling can be spliced by the installer. However, a long cable run
can give rise to electronic noise problems in certain environments. It should therefore be
avoided where possible and in no case should cable length exceed 30 ft. (10 meters).

Cable entry to the CPU board enclosure can be handled in one of two ways. There is a hole in
the bottom of the enclosure, the use of which creates the most attractive installation as the
cable is completely hidden. Alternately, there is a side knockout in the enclosure cover which
permits surface mounting of the cable. The side knockout also permits a wiring technique

which is convenient when the CPU board enclosure is to be mounted in an awkward
location such as above a drop ceiling. You can pop the board itself out of its snap track and

make all your connections with the board in your hands. The board is then re-snapped into the
plastic trak. The enclosure cover snaps on with the wires emerging from the side kno ckout. If
you use this technique, avoid touching the components or rear pins on the board as

much as possible. Static electricity can destroy the processor. Also when you snap the
board back in its track, make sure it’s securely done. Sometimes you need to squeeze the

outer lips of the track to insure that the board edges are really seated in the slot.

3. WIRING

3.1 POWER, DATA AND KEYPAD WIRING

Note that the cable connector plugs into the rear of the circuit board
which is on the opposite side of the keypad. It is possible to plug the
cable connector incorrectly, so follow the drawing to the right for corre ct
orientation. Also, be careful not to pull on the cable as you route it
towards the CPU board or you could pull the connector out.

Figure 1 shows the DK-16W CPU Board. You will make connections to
the 18 terminals as shown in the drawing and either leave the jumper
block in the factory set position (connects pins 2 and 3) if you plan to
power the DK-16W with 12 VDC or move the jumper to connect pins 1
and 2 if you will be using 5 VDC. Note that operation at 12 volts with
the jumper block in the 5 volt position can damage the unit.

Note that the DK-16W will not operate on AC power. It will, however, accept full wave
rectified DC power (transformer + bridge rectifier) when it is being powered by 12 VDC.
When it is being powered by 5 VDC, the voltage must be regulated (+/- 1/2 volt). Be sure
to observe polarity when you power the DK-16W.

There are 12 color coded wires in the keypad cable. Refer to Figure 1 an d connect each wire to
the indicated terminal on the CPU Board. No other connections may be made to these terminals
(except if two keypads are used with one CPU board).

The DK-16W will draw a maximum of 30 mA at 5 VDC or 12 VDC.
The Weigand output terminals: Data 0 and Data 1 connect to the appropriate inputs of the

access control system. The wire run maximum distance for reliable operation depends on the
wire gauge. A guide line is 200 ft. for 22 gauge; 300 ft. for 20 gauge and 500 ft. for 18 gauge.

3.2 LED AND “TRANSMIT DATA” WIRING

The LED’s on the DK-16W follow the convention for card readers. When a “high” signal (+5
VDC) is connected to the LED terminal, the red LED will be on and the green LED will be off.
