1. INTRODUCTION
Figure 1, CC-8521ANCrypto-Lock
The Crypto-Lock Model CC-8521ANis a
versatile, easily installed and operated
single door access control system. It
provides reliable keypad access control
using a single 3, 4 or 5-digit PIN code for
all users.
The system, pictured in Figure 1, includes
a built-in 12Vdc and 24Vdc, 2A power
supply to power electric strikes and
magnetic locks, eliminating the need for a
separate power supply unit. It provides the
high in-rush currents required to reliably
open heavy duty locking devices such as
Von Duprin* rim latch retraction units and
Sargent & Greenleaf Brute* electric locks.
A unique, switch selectable current limiter
safely achieves continuous activation of
large solenoid-operated locks. This
feature limits the current to a value that
will reliably hold the lock open without
damaging its solenoid.
The power supply includes a battery
charger and monitoring circuit that
automatically maintains optional batteries.
Regulator Q3 provides 13.5Vdc at up to
2A to relay K1 when the OUTPUT
SOURCE switch is set to INT 12V.
The length of time that the lock remains
released after entry of the valid PIN is
adjustable from 3 to 60 seconds. An
invalid PIN penalty feature provides for
ignoring all keypad entries for from 3to 60
seconds after an invalid digit is entered.
This greatly reduces the possibility of
gaining access by guessing PIN codes, and
is particularly effective when shorter PIN
lengths are used.
The stainless steel keypad includes a green
LED that illuminates when the lock is
released.
A visitor button on the keypad activates an
annunciator in the control unit and also
generates an output voltage for an external
device.
Installation and set-up are readily
accomplished using the wiring diagram
affixed inside the enclosure door and also
contained in this manual. Slide switches
set the PIN length (3, 4or 5 digits), output
voltage (12 or 24 Vdc), and enable or
disable holding current limiting. Five 10-
position DIP switches are used to set the
PIN. The open duration time and penalty
time are set using analog control knobs.
The CC-8521ANcan be wired to operate
on either 115 or 230 Vac, 50 or 60 Hz. It is
wired at the factory for 115 Vac.
A typical installation of the CC-8521ANis
illustrated in Figure 2.

6. OPERATING PROCEDURE
To operate the CC-8521AN, enter the
valid 3, 4, or 5 digit PIN code on the
keypad. When the valid PIN code is
entered, the green LED on the Keypad
will illuminate and the door will release.
The CC-8521ANKeypad has a built-in
annunciator button. Pressing this button
causes an annunciator to sound in the
Control Unit. If an external annunciator is
connected as shown in Figure 3 it will also
sound when this button is pressed.
If one or more incorrect PIN code digits
are entered the system will enter a penalty
mode and will not recognize any digits for
the time period set by the PENALTY
control on the Logic Board in the Control
Unit. After the penalty time has elapsed
the unit will return to normal operation and
entering the valid PIN code on the Keypad
will release the door.
If the external Release Button has been
installed it can be used by an attendant to
release the lock from the secure side of the
door.

7. THEORY OF OPERATION
A. GENERAL
The CC-8521ANCrypto Lock consists
of two main units, the Keypad and
Control Unit.
B. KEYPAD
Refer to the Keypad Schematic Diagram
on moniteq.com. The Keypad contains a
telephone-type key switch, an LED
indicator lamp and an annunciator push
button.
The Control Unit contains the Logic
Board, the Power Supply Board and the
Power Transformer.
C. LOGIC BOARD
The Logic Board processes key strokes
from the Keypad to determine if the lock
relay should be energized based on the
PIN code set on the DIGIT DIP switches.
The Logic Board also accepts the input
from the Annunciator Button on the
Keypad for routing to the Power Supply
Board, and generates a signal to illuminate
the green LED on the Keypad when a valid
PIN code has been entered.
Chip U4 is a divide-by-8 counter that
decodes successive inputs from the
Keypad. The decoded outputs of U4 are
coupled through the respective DIGIT DIP
switches (S1,2,3,5 and 7) to U4's Clock
Enable input. If a valid first digit is
pressed the high signal on the "0" decoded
output (U4, pin 2) is coupled through the
valid number's key switch through T1 pin
11, U2C and Q4 to the clock enable input
of U4, advancing the counter one count
and causing the "1" decoded output (U4,
pin 1) to go high. If the second digit from
the keypad is also valid the process repeats,
again advancing the counter. When the last
correct digit is entered a high signal is
coupled to both inputs of gate U2:B that then
triggers the Open Timer, U1:B. The output
of U1:B then remains high for a time period
set by the DURATION potentiometer R19.
This output is coupled to Relay Driver Q5
which grounds the signal connected to the
door control relay on the Power Supply
Board.
If an incorrect digit is entered on the Keypad
the divide-by-8 counter U3 is advanced one
count, thereby triggering Penalty Timer
U1:A that resets Open Timer U1:B for a
time period set by PENALTY potentiometer
R8.
D. POWER SUPPLY BOARD
The Power Supply Board contains the power
supplies for powering both the internal
circuits and driving the external locking
device. It also manages the standby batteries
and routes signals from the external release
button to the Logic Board and from the
Logic Board to the external annunciator.
The 24Vac output from the secondary of the
power transformer is applied to bridge
rectifier D2 and filter components C4, R3
and C2 and regulator Q2 to generate
27.3Vdc. When OUTPUT SOURCE switch
S2 is set to INT 24V and OUTPUT MODE
switch S1 is closed, this voltage is coupled
through door control relay K1 to either pin
10 or pin 11 of T2 depending on the status

14
Regulator Q4 provides operating voltage
for circuits on both the Power Supply
Board and through T1, pin 4, to the Logic
Board.
Regulator Q5 provides operating voltage
for the battery monitoring circuits of U1
and U2. U1:A compares the battery
voltage (T2, pin 6) with a reference voltage
to determine the battery charge level.
When the level falls below that of the
reference the output of U1: A trigger timer
U2, causing L2 to flash and beeper B1 to
sound approximately every 30 seconds.
The annunciator
control signal from the
Logic Board enters through T1, pin 6 and
is coupled directly to the external
annunciator through T2, pin 16.
Terminals T3 and T4 are provided to
allow wiring the power transformer
primary winding for either 115VAC or
230VAC. Refer to Figure 3 for correct
wiring of T3 and T4.
of K1. Capacitor C3 provides additional
"in-rush" current immediately after K1
closes to assure activation of the solenoids
in larger, heavy-duty electric locks. K1 is
controlled by an input from the Logic
Board on T1, pin 2 (RELAY-). When
OUTPUT MODE switch S1is in the
LIMIT HOLDING CURRENT position the
output current is limited to approximately
300mA after capacitor C3 discharges. This
serves to prevent overheating and possible
damage to solenoid-operated locks that
otherwise could not be maintained open for
long periods of time.
Regulator Q3 provides 13.5Vdc at up to
2A to relay K1 when the OUTPUT
SOURCE switch is set to INT 12V.
