The CL-8 is a self-contained, versatile microprocessor-controlled
digital keypad for indoor access control and remote control
applications in security systems. Its main purpose is to limit
access to restricted areas, while permitting authorized personnel
to enter. Small and simple to operate, this keypad is suitable for
surface mounting or flush mounting in a standard single-gang
switchbox. It can function with virtually every security control
panel on the market, protecting residences, factories,
laboratories, hotels, offices and airports.
The CL-8 internal EEPROM can be programmed with 56
individual access codes, each assigned to an authorized
individual user or to a group of users. Each code may be changed
or deleted by application of a simple, straightforward
programming sequence. On-site programming is carried out at
the keypad, but only the MASTER CODE holder can access the
programming menu. The programming process is aided by a
green LED which shows programming information to the installer.
When an access code is keyed-in and identified by the
microprocessor, the CL-8 energizes a built-in 10A relay, which
operates the door strike or performs any desired switching
function. The relay remains energized from 1 to 98 seconds,
depending on the contact closure duration programmed into the
device. For special applications, the relay may be toggled by user
access codes, so that keying a code once causes the relay to
latch, and keying a code again unlatches the relay.
In addition to the on-board relay, an auxiliary (AUX)
open-collector transistor output may also be tripped by certain
code users for activating a control panel, operating floodlights,
switching on CCTV, sounding a buzzer etc. Each of the 56
different access codes may be programmed to operate the
built-in relay, the auxiliary output or both. Moreover, the auxiliary
output can be programmed to function in seven different modes,
one of which is the "double keystroke" (pressing keys 1 and 3
simultaneously). A different double keystroke - pressing the * and
# keys simultaneously - activates a special PANIC
open-collector
transistor output to send out a "silent alarm" in emergency
situations. A REQUEST TO EXIT
remote input trips the relay to
open the door from inside without entering a code, thereby
permitting simple exit from the protected area. When the access
code is being entered under duress, the authorized user can add
a preset
AMBUSH
digit immediately after his access code, thus
actuating the PANIC signal. In addition, the CL-8 is virtually
impossible to defeat by unauthorized people who try to discover a
correct code by trial and error: a penalty timer locks out the
keypad for 30 seconds after three consecutive inputs of
erroneous codes.
Model CL-8A, with an extended
operating temperature range is
supplied for use in uncontrolled
temperature environments.
Model CL-8A EXT is designed
to operate in conjunction with
outdoor, vandal resistant
keyboards KB-81 and KB-82,
with which it forms access
control systems CL-81 and
CL-82, respectively (see
Publication D6215). An optional
tamper switch for both models is
available upon request.
