The CL-4WB is a digital, wireless multi-function keypad unit,
especially suitable for electronic security systems. It is designed
to transmit a radio frequency (RF) signal to a remote receiver as
soon as the user enters a pre-programmed, 4-digit secret access
code.
Applications of the CL-4WB include: remote arming and
disarming of control panels, operating doors, gates, etc. The unit
can be easily incorporated into virtually any new or existing
Visonic Ltd. wireless system.
The transmitted RF signal consists of two digital codes - a
SYSTEM code and a CHANNEL code, which perform the
following functions:
•
The SYSTEM code serves as a password – the remote
receiver ignores RF signals other than the correctly coded
ones. System code matching between the CL-4WB and the
remote receiver is obtained by selecting identical settings on
an 8-position CODE switch in both units. It is possible to select
256 different system codes (para. 3.3).
•
The CHANNEL code determines which one of the remote
receiver
outputs will be activated by the
transmitted RF signal. This code
is selected by presetting the
CL-4WB's 4-position
"CHANNEL" selector (para. 3.4).
"Channel 2" code is dedicated to
tamper and PANIC alarms (a
PANIC alarm signal is
transmitted when the k and #
keys are pressed
simultaneously).
The CL-4WB is powered by a 9-volt
alkaline or lithium battery. Its plastic
housing is suitable for wall
mounting and opens by removal of
a single screw. A short antenna
wire extends from the bottom of the
case.

ELECTRICAL
Voltage: 9-volt alkaline or lithium battery.
Keypad: 12 keys, 3 x 4 tactile operation
Security Code: 4-digits, jumper selectable - 5040 different code
combinations.
Code Combinations: 5040 (the codes are not lost due to power
failures).
Automatic Reset: 5 seconds
Panic Output: Activated by simultaneously pressing the
∗
and #
keys. Channel code 2 is transmitted as the panic signal, while
these keys remain depressed.
Tamper Switch: Normally closed. Channel code 2 is transmitted
as a tamper signal, when the keypad assembly is separated from
the back cover.
Visual Indications: Red LED lights during transmission,
provided that the battery voltage exceeds 7.5 Volts. The indicator
is inhibited during transmission of the tamper and panic signals
(channel 2 code).
System Code: 8-bit digital word, 256 combinations, pulse width
modulation.
Channel: 4 switch-selectable channel codes: 1, 2, 3 and 4.
Frequency (MHz): 315, 304, 404, 418, 433.92, 224.7 or other
frequencies according to local requirements.

The CL-4WB is triggered into transmission by a 4-digit security
code entered by the user on its front panel keypad. The installer
programs the selected security code by linking a few on-board
terminals. This programming method ensures that the code is not
lost due to power failures or electrical disturbances.
To initiate transmission, the user is required to enter the correct
(programmed) four digit code in proper sequence within about 5
seconds.
Should the user take more time than permitted, or if the user
makes an error while entering a code, an automatic reset results,
requiring the user to wait a few seconds and then repeat entry of
the security code. This feature virtually prevents unauthorized
people from defeating the code by randomly pressing keypad
buttons.
Once the correct code has been entered, the keypad's transmitter
operates for 2 - 4 seconds. A front panel LED lights during
transmission, indicating the battery status (provided that the
battery voltage is above 7.5 VDC). If the LED does not light
during transmission, the battery must be replaced immediately.
Note: For security reasons, the LED does not light when the
tamper alarm or panic alarm are transmitted (Channel 2).
CAUTION: The keypad is only for indoor use.
DO NOT INSTALL OUTDOORS!
