THE LIBRA-DXK4RF SERIES KEYPAD

DESCRIPTION

The LIBRA-DXK4RF series keypad is a multi-segment LCD digital keypad that is compatible with the LIBRA LIB­P432EX, LIB-P432EXT, LIB-P432EXT-230 control panels. Refer to User Guide OI349 for keypad operation
instructions. While the LIBRA-DXK4RF series keypads may be used to fully program the control panel, the

GEM-DXRP1 or GEM-DXK1 keypads, with their easy to read two-line LCD displays, provide the optimum in
ease of keypad programming. Note: Do not mix "RP" series keypads with "K Series" keypads within one system.

The wireless system comprises a compatible LIBRA LIB-P432EX series control panel, at least one LIBRA-RECV re­ceiver and one or more companion LIBRA-Series transmitters. Built inside the LIBRA-DXK4RF series keypad is a re­ceiver to save space and simplify installation. The transmitters may be wireless smoke detectors, space-protection de­vices, window/door sensors, or other devices that report zone status and supervision information to the receiver with­out the use of wires.

The integral receiver inside the keypad will accommodate up to 32 wireless points. The receiver is connected to the
control panel's 4-wire bus through the same 4 wires as the keypad. The receiver monitors each transmitter, updating
transmitter status as reports are received, and conveys this information to the control panel. Also monitored is the
elapsed time since the last report from each transmitter. If no report is received within a programmed time, a Supervi­sory Failure will result.

INSTALLATION

Designing the System

A keypad should be located near each exit/entry door. However, give careful consideration to the location of the key­pad, since it has a receiver built inside it. Regardless of where the control panel is mounted, the keypad should be
centrally located within the premises, that is, equally distant from all transmitters. Metal objects close to the installation
may adversely affect reception. Draw a layout of the system, identifying all proposed transmitter locations and antici­pated keypad location. Also include notations indicating construction materials in use. Although wood and wallboard
construction will have little effect upon signal strength at the receiver, concrete or brick can reduce signal strength by
up to 35%, while steel-reinforced concrete or metal lath and plaster can reduce transmitter strength as much as 90%.
Note: In difficult installations wherein distant transmitters pose reception problems, the use of multiple keypads and/or
LIBRA-REC16433's throughout the premises is recommended. (The LIB-P432EX control panel will accommodate up
to two receivers). Receivers are connected to the panel's 4-wire bus. They should be uniquely addressed (see AD-
DRESSING MULTIPLE RECEIVERS). Note: If receivers are intermixed, the panel will only recognize the capacity of
the lowest one.

After determining the general location for the keypad, additional time should be spent determining the exact location of
keypad using the template provided. In addition to the hole in the wall used to connect the bus wires to the keypad, an
additional hole should be made into the wall to allow the antenna wire to be recessed into the wall. The design of the
keypad keeps the antenna as far away from the bus wires as possible so that RF noise emitted from the bus wires
does not affect the sensitivity of the receiver. If the placement of both these holes are not carefully considered, addi­tional effort may be required to drill through or chisel existing wall beams. In addition the tamper is located close to the
antenna hole. If care is not taken to leave sufficient space between the antenna hole and the tamper, the tamper may
not function correctly.

To open the case, insert a screwdriver into either slot at the bottom and push up with a slight twisting motion to release
the retainer tab. Repeat for the other slot. Pull out at the bottom and lift off the two hooks at the top.
The LIBRA-DXK4RF series keypads feature a handy pull-up reference label. Before mounting the keypad onto the
wall, push the Sliding Label Plate (with label and felt backing affixed and handle facing forward) down the guides at the
rear of the keypad until it snaps into place. Once installed, the Sliding Label Plate cannot be removed without first
removing the keypad from the wall. Note: The keypad fire and panic keys should not be considered a substitute for a
listed manual initiating device, such as a pull box.
If installing onto a double-gang box, insert mounting screws through the two vertical elongated holes on the left side of
the case and into the box. If the box is visible when viewed from the front, adjust the keypad vertically and tighten the
screws. Then, using hardware suitable for the mounting surface, add one or two screws at the right side of the keypad
case directly into the wall to ensure a secure installation. Note: Do not over tighten the screws! Uneven walls may
cause the keypad case to distort.

WIRING

After the bus wires are brought through the bus wire hole, and the keypad back case is
mounted the wires can be connected as shown in the table at the right. After connecting the
wires care must be taken to loop the antenna wire carefully into the antenna hole as the
front cover is connected to the keypad back case. The antenna should fall easily into the
wall cavity away from the keypad bus wires. The wire should hang as straight as possible
below the keypad for optimal reception. If the wire cannot be hung inside the wall, it is better
for the wire to be cut flush with the printed circuit board rather than to have the wire become
tangled behind the keypad.

KEYPAD AND RECEIVER ADDRESS JUMPERS

If more than one receiver is being utilized, each must be individually addressed so that it can be identified by the con­trol panel. This is accomplished by the placement of jumper "RX" located in the upper right corner of the back of the
keypad, as shown below. Factory default is no jumper, therefore making the receiver inside the keypad as RF Re­ceiver #1. With the jumper in place, it is receiver #2. Refer to the Wiring Diagram for jumper configuration. Note:
Each receiver leaves the factory internally configured as #1, therefore, if only one receiver is being used, address as­signment is not required.

In summary, if more than one keypad is installed:

• Each must be assigned a unique address (that is, no two keypads may be numbered alike).

• Keypads must be addressed consecutively (that is, missing numbers are not permitted).

• Only Keypad No. 1 may be used for programming. (However, for ease of programming, it is recommended that a

GEM-DXK1 be selected as Keypad #1).

Up to seven (7) LIBRA-DXK4RF series keypads may be addressed to the control panel (Keypads 1–7).

Keypads are configured by the proper selection of jumpers. Refer to the label on the keypad circuit board for jumper
locations and a summary of settings. The keypad may be configured to disable touchpad backlight and entry sounder.

numbers and/or letters, including leading zeros, if any);

• Aux. 1 options (see programming worksheets);

• Aux. 2 options (see programming worksheets).

Quick Method (Using the GEM-DXK1 keypad)

If a receiver is already installed in the panel, Napco Transmitter wireless points can be programmed automatically
("enrolled"). Note: (1) The transmitter point will be enrolled only if the signal strength is 3 or greater. (2) Enroll a sin-
gle-point device by merely powering it up. (3) Quick Method is not applicable to keyfob transmitters.

Enter the Program Mode. Scroll to the RF Transmitter Points entry screen and proceed as follows:

1. Enter the zone number to which the transmitter point will be mapped.

2. Press

x to enter the Enroll Mode. The red and green LED's on the keypad will flash and will display as shown

below (GEM-DXK1).

ZN# XMIT#+CS P

3. Open the loop of the point that is to be programmed.

4. Install the transmitter battery. The keypad will indicate that the point has been successfully enrolled.

Multi-point transmitters can be mapped to successive zones simultaneously (Example 1) or to selected point by point
(Example 2).

Example 1: A 2 point transmitter has the ID Code number 410078. Map the two points to Zones 11 and 12 respectively.

1. Enter the Enroll mode as described in step 2 above.

2. Enter Zone "11".

3. Open the loops of points 1 and 2.

4. Install the transmitter battery. The keypad will beep twice to indicate that two points have been enrolled.

• Transmitter 410078, point 1 will be mapped to Zone 11

• Transmitter 410078, point 2 will be mapped to Zone 12

The keypad will now display Zone 12, the last zone enrolled.

Example 2: A 2-point transmitter has the 1D Code number 287613. Map point 1 to Zone 6 and point 2 to Zone 9.

1. Enter the Enroll mode as described above.

2. Enter Zone 06.

3. Open point-1 loop.

4. Install the battery. The keypad will beep once to indicate that one point has been programmed. (Transmitter point
1 will be mapped to Zone 6).

5. Enter Zone "09"

6. Open point-2 loop.

7. Remove the transmitter battery, then re-install it. The keypad will beep once to indicate that one point has been
programmed. (Transmitter 287613, point 2 is Zone 9).

CHECKING TRANSMITTERS

The status of each transmitter may be checked at the keypad. Referring to the control panel installation instructions
and the user's guide for the keypad in use, display transmitter status to show (a) the zone to which transmitter point is
mapped; (b) the transmitter's 6-digit RF ID number (c) the point number; (d) transmitter status (normal, open, low bat­tery, etc.); and (e) the signal strength of its last transmission.

Testing Wireless Signal Strength

To test the operation of wireless transmitters, proceed as follows.

 1. Enter the Fault-Find Mode from the Function Menu (use Dealer Security Code to enter).
 2. Fault a point of the transmitter to be tested by opening the loop. If the signal strength of the transmitter is 3 or

greater, the keypad will beep, as follows:

5

WIRELESS SIGNAL STRENGTH
Signal Power Beeps

0-2 0

3 1
4-5 2
6-7 3

8-10 4

 3. Restore the wireless point (close the loop). When restored, the keypad will beep once regardless of signal

strength.

Note: With the LIBRA-DXK4RF series keypads, signal strength is not displayed but is annunciated by beeps as per the
above table. For installations that include several transmitters, multiple receivers may be connected to the panel. (Only
the highest signal strength will be displayed). Note: When using the Fault-Find Mode on wireless zones, the keypad will
beep when the zone is opened or closed only if the signal strength of the transmitter is 3 or greater. Signal strengths
less than 3 will be entered into the system log (except in the Fault-Find Mode).
