Visonic CL8A User Manual
CL-8A, CL-8A T
Microprocessor Controlled Digital Keypads
1. INTRODUCTION
1.1 Description
The CL-8A and CL-8A T (version with tamper
switch) are digital, code-operated keypads for
indoor access control and remote control
applications. The keypad can function with virtually
every security control panel on the market, and is
suitable for surface mounting or flush mounting in a
standard single-gang switchbox.
1.2 Features
• Self-contained, suitable for flush and surface mounting;
supplied with a surface mounting box.
• Includes a 10 A relay, which operates the door strike or
performs any desired switching function.
• Programmable on site by use of its own keyboard.
• Non-volatile EEPROM stores programmed data;
unaffected by power failure.
• Up to 56 different 1-8 digit user codes can be programmed.
• More than 100 million code combinations are possible.
2. SPECIFICATIONS
Code composition: 1 to 8 digits, any combination
Keypad type: 12 keys, 3 X 4, tactile operation
Operating voltage: 9-16 or 22-26 V AC/DC, selected with jumper
Current drain: 15 mA in the standby state, 55 mA with relay and
AUXILIARY output active
Power failure immunity: EEPROM retains all programmed
information even during total power loss
Other protections: Watch-dog protection from processor hang-up.
Relay control: Programmable for 1 – 98 seconds pull-in duration,
or for toggle (latching/unlatching) mode
3. INSTALLATION
3.1 Mounting
Do not install outdoors! Flush mounting is possible in standard,
single-gang electrical switch boxes (see Figure 1), without the
original back box. For surface mounting, use the back box
supplied with the unit (Fig. 2).

3.2 Wire Gauges and Routing
Use # 20 AWG or larger diameters for relay connections to the
door strike, to the control panel or any other system used. All
other connections are to be made with # 22 AWG or larger. Route
the wires through the wiring knockouts on the back box.
3.3 Wiring
IMPORTANT! Before wiring be sure to set jumper JP3 in the position
that corresponds with the power source you are using:
9 - 16 Volts - mount the jumper across the two pins of JP3.
22-26 Volts - remove the jumper or mount it on a single pin of JP3.
(1 OF 2)
IMPORTANT:
power source is used, LEDs
connected to the PANIC or AUX
open-collector outp uts will light
normally when the output p ulls
down. Buzzers will not function
properly, and should therefore
be avoided.
When a 24VAC power source is
used, neither LEDs nor buzzers
should be connected to the
PANIC and AUX outputs.

*Notes:
1.
If the CL-8A/CL-8A T is powered from a DC power supply,
the AUX and PANIC relays can be connected to terminal
7 (+).
2.
The PANIC and AUXILIARY outputs each include an 18
ohm resistor in series with the output. The maximum
current switching capability of each output is 100 mA.
**Caution! If the power supply provides AC, disregard
polarity. If the power supply provides DC, connect the
negative lead to terminal 6 and the positive lead to terminal 7.

across terminals 5 and 6. To light the red LED, connect the
12 or 24-Volt power supply across terminal 1 (+) and 2 (–).
To light the yellow LED, connect the 12 or 24-Volt power
supply across terminals 3 (+) and 4 (–).
3.4 Tamper Switch TAMP-1 (optional)
This option includes a terminal block and a tamper switch on a
separate PC board. The tamper switch can be used in two ways:
4. OPERATION
The main function of the CL-8A/CL-8A T is to recognize valid user
codes and respond according to pre-programmed instructions.
4.1 Keying Format
The user code is always followed by [#]:
4.2 Keypad Response
When a valid access code is keyed, the keypad responds by
activating the on-board relay (usually allocated to unlocking the
door), and/or activating the auxiliary circuit. Each of the 56
different access codes may be programmed to operate the onboard relay, the auxiliary output or both. The green LED
illuminates for as long as the internal relay remains energized.
4.3 Latching the Relay
For special applications, the relay may be toggled, so that keying
the code once causes the relay to latch, and keying the code
again unlatches the relay.
4.4 Request to Exit
The REQUEST TO EXIT input activates the access control relay
to open the door from inside without keying a code, thereby
facilitating quick and simple exit from the protected area.
4.5 Automatic Reset
When keying user codes, the intervals between digits must not
exceed 5 seconds. Should the user exceed this time, or enter a wrong
5. PROGRAMMING
Programming should be carried out as soon as installation is
completed. This provides a set of “instructions” which determines
how the keypad will react to various code inputs.
Programming changes can be made as many times as
necessary, but for security reasons, this operation is restricted to
the “master code” holder (the master user).
5.1 Accessing the Programming Menu
The programming menu is accessible only by the master user
As soon as code programming takes place, this default code is
automatically replaced by the first newly allocated code - No. 01.
Because user code No. 01 will become the new master code, it
should be assigned to the person in charge of security.
All code allocations should be recorded, and a User Code
Programming Chart - Appendix A, is supplied for this purpose.
Remember! To prevent unauthorized programming, it is
important to assign a new master code which should be used
for programming only.
To access the programming menu:
The green LED will start flashing slowly, indicating that the programming menu is active. You can now select various programming functions
by pressing a number key from 1 to 5 (see Table 1).
A. To protect the CL-8A if tampering is attempted by removal of
the front part of the case. In this configuration, the tamper
actuator remains within the case, in physical contact with the
inner surface of the keypad’s back box.
B. To protect the CL-8A if tampering is attempted by removing the
unit from the wall or by removing the front of the case. This is
accomplished by opening the tamper knockout in the back box,
allowing the tamper actuator
to extend out of the back box
and contact the wall (see
Fig. 4).
Note: The tamper switch is
delivered as a separate item.
For ordering, specify TAMP-1.
Note: When using a tamper
switch, connect the tamper
N.C. terminals to a control
panel’s normally-closed, 24hour protection zone, or any
other system used to monitor
the tamper contacts

code, an automatic reset results, requiring the user to wait a few
seconds and then to repeat entry of the security code again.
4.6 Lockout
A penalty lockout is provided to defeat “code-crackers”. Three wrong
entries result in a 10 minute lockout, during which an auxiliary output
is activated, but the keypad can be reset after 30 seconds by entering
a valid user code.
4.7 Access under Duress
If you are forced to access under threat, press the programmed
AMBUSH digit after the last digit of your code. This activates the
PANIC
output without arousing suspicion.
Enter the user code followed by the ambush digit
4.8 Operating Tips
A. Do not wait more than 5 seconds between successive
keystrokes, or else the keypad will reset.
B. To initiate an alarm without opening the door, press
simultaneously. This activates the PANIC circuit which is
usually connected to a silent alarm.
