920
EntryCheck™
The EntryCheck™ 920 Indoor/Outdoor Keypad is a surface-mount digital keyless entry system designed for access control applications. The backlit keys are bright and easy to read. A heavy cast vandal-resistant housing design with a mounting plate allows the 920 to be mounted on a rugged surface or on a standard single-gang electrical box.
The 920 has a capacity of 500 users. Users can be assigned to use 4 to 6 digit
PIN codes. An authenticated access can be programmed to activate one or both
of the onboard relay outputs. The timed “anti-passback” feature prevents using
the same credentials twice before a programmed waiting period has elapsed. Two
long-lasting solid-state LED indicators show the status of the system. The
left bi-color indicator lights red to indicate power, then solid green when a
relay is active (access grant, etc.). The right indicator flashes yellow to
indicate that the keypad is in programming mode. An internal sounder can be
programmed to beep each time a key is pressed or when output is activated. An
internal jumper sets the sounder volume high or low.
The SENSE input can be configured in two ways through programming. When
configured for “Door Sense”, the input is wired to a normally closed door
position switch to detect when the door is opened or closed. Forced entry or
door ajar situations can then be detected. The “Auto-relock” feature can also
be used to turn off the Main Relay output immediately when the door is closed
after access has been granted to prevent “tailgating”. When the SENSE
input is configured for “Inhibit”, the input can be wired to a normally open
“service” switch or automatic timer that will disable access while the switch
is closed.
The REQUEST-TO-EXIT input can be wired to a normally open pushbutton to provide codeless activation of the Main Relay, Auxiliary Relay, Output #3, or Output #4 (user-programmable).
The ALARM SHUNT signal is available when access is granted. This signal can be
programmed to activate any of the relays or solid-state outputs to shunt alarm
contacts on the access door/gate preventing the triggering of an alarm when
authorized access occurs.
The 920 EntryCheck™ is powered from a 12 or 24V AC or DC source. The non-
volatile EEPROM memory retains entry codes and programming when power is
removed. An internal jumper is provided to reset the master code. The Main
Relay has a 5 Amp capacity. The Auxiliary Relay has a 2 Amp capacity. Two
solid-state outputs, capable of sinking 100 mA to common are programmable for
alarm shunting, or to signal forced entry, door ajar, keypad lockout, request-
to-exit, and keypad active conditions.

KEYPAD WIRING
See Fig. 3 for an example of a basic door installation. The keypad is mounted
adjacent to the door. An electric door strike is mounted in the door jamb to
release the door lock. An optional door contact switch is mounted on top of
the door jamb for detecting when the door is open.
Use the following steps to wire the keypad. Refer to the wiring diagram shown
in Fig. 4 to assist in the wiring.
Note: For lock power, use 18 AWG wires or larger (depending on load). Use
22 AWG or larger for signal connections. Refer to lock manufacturer’s
documentation for lock power requirements.
Output Connection
Install a low-voltage fail-secure electric door strike at the door to be
controlled. Route 2 wires from the door strike to the keypad. Connect a MOV
across the coil wires of the strike. Connect the (+) door strike wire to the
keypad’s MAIN RELAY N.O wire (yellow). Connect the other door strike wire to
the keypad’s PWR(-) wire (black). Connect the keypad’s MAIN RELAY COM wire
(white) to the keypad’s PWR(+) wire (red).
Power Connection
Connect the power supply’s output terminals to the keypad’s PWR(+) wire (red)
and PWR(-) wire (black). If using a DC supply, observe wiring polarity. If an
AC transformer is being used, polarity does not matter.
Caution: If the unit is AC powered, make sure the secondary of the system
transformer is isolated from the earth ground.
Earth Ground
To avoid damage to the unit from static discharges, this unit must be
connected to proper earth ground. Connect the green earth ground wire to a
good earth grounding point. The suggested wiring size is 18 AWG for the earth
ground.
Sense Input
RE Note: The SENSE input (gray wire) can be programmed as either a door sense or inhibit input (default). Both features cannot be used at the same time.
Door Sense: (Detect forced entry or door ajar conditions) Install a normally closed door switch on the door and route two wires from the switch to the keypad. Connect the door switch to the keypad’s SENSE wire (gray/ E8) and COM wire (any black wire).
Inhibit: (Disable access) If an inhibit switch or timer is going to be used for temporarily disabling the keypad, route two wires from the switch or timer to the keypad. Connect the inhibit switch/timer’s normally open contacts to the keypad’s SENSE (gray/ E8) and COM (black wires) terminal.
Request-to-Exit Input (wiring shown on fig. 4)
If a request-to-exit pushbutton is going to be used, route two wires from the
keypad box to a normally open pushbutton mounted on the secure side of the
door. Connect the wires to the pushbutton and to the keypad’s REX wire
(violet/ E6) and COM (black wires) terminals.
Solid State Outputs
The two solid-state outputs (Outputs #3 & #4) can be programmed to activate
during various conditions. These “open collector” outputs can be used to
activate indicators or sounders. See fig. 5 for wiring examples using the
solid-state outputs.

BASIC PROGRAMMING
When the 920 EntryCheck™ is in Programming Mode the yellow indicator will blink slowly. After a programming command is selected, the yellow indicator will flash rapidly while the keypad is waiting for user input data. The green indicator will light if the dais is accepted. The red indicator will light if any programming data is entered incorrectly, and the command will have to be fully reentered.
Entering Programming Mode
The 6-digit Master Programming Code (default = 123456) is usedto enter
Programming Mode.
Press: # 9 # Master Code #
Master Code = the current 6-digit Master Programming Code
Exiting Programming Mode
Press: #
The red indicator will light after exiting Programming Mode
Note:** The 920 will automatically exit Programming Mode after 30 seconds
of inactivity
NOTE: You must be in Programming Mode to perform any function beyond this
point.
Re-entering a Command After a Mistake
If the red indicator lights, signaling an incorrect entry, or an incorrect key
is pressed during programming, to clear the keypad and re-enter the command:
*Press: 9 #
Setting Entry Code Length
Default: 4 digits
Press: 03 # Length #
Length = 1-6 for entry code length
Note:** If the Entry Code Length is going to be changed from the factory
default of 4 digits, make this change first before programming any entry
codes.
Adding a New PIN Code
Press: 0 1 # Code # Code # Relay #
Code=The new entry code: 1-999999, depending on code length
Relay=Relay output entry code will activate:
1=Main Relay 2=Auxiliary Relay 3=Both Relays
10=Relay #1, toggled 20=Relay #2, toggled 30=both Relays toggled
12=Relay #1 toggled; Relay #2 timed open
21=Relay #1 timed open; Relay #2 toggled
The green indicator will light momentarily when the new code is accepted. If the user number already exists or an entry error has been made, the red indicator will light. Delete the user and re-enter the new information again.
Note: Leading zeros (zeros before the code number, e.g. 0241) do not need to be entered when programming a new code. The 920 will internally add any zeros to fill digits determined by the entry code length setting. Leading zeros will have to be entered by the user when entering their code to gain access.
Output Toggle Mode
When an output is programmed for Toggle Mode, the output alternates from OFF
to ON or from ON to OFF each time it is accessed. When an output is toggled
on, the green LED remains solid until toggled off.
The rules for a toggle output are:
If the output is OFF, entering a toggle code will turn ON the selected
relay, and stay on until the next activation of a toggle code. NOTE:
Entering a timed code OR activating the REX input will not turn off a relay
that has been toggled ON.
If the output is ON, entering a toggle code will turn OFF the selected relay and stay off until the next activation of a toggle code, time code, or REX.
Erasing a Single User
Press: 02 # Code # Code #
Code = The PIN code to be deleted
The yellow indicator will flash quickly while the 920 erases the user from
memory. The green indicator will light when the code is erased.
See the following example that sets entry codes 1234 for normal operation of the main relay, and 5678 for toggle operation of the auxiliary relay.
Press: 01 # 1 2 3 4 # 1 2 3 4 # 1 #
01=Add PIN function; 1234=Entry Code; 1=Main Relay
Press: 01 # User # 5 6 7 8 # 5 6 7 8 # 20 #
01=Add PIN function; 5678=Entry Code; 20=Auxiliary Relay toggle
Once all PIN codes are programmed, it is recommended the default Master
Programming Code be changed using the function below.
Changing the 6-Digit Master Programming Code
Press: 98 # Master Code # Master Code #
Master Code=The new 6-digit Master Programming Code
Erasing All Entry Codes
WARNING: PERFORMING THIS COMMAND WILL REMOVE ALL ENTRY CODES FROM THE
MEMORY
Press: 97 # 0 0 0 0 0 0 # 0 0 0 0 0 0 #
Note: The green indicator will light while the memory is being erased.
This may take up to 15 seconds.

INHIBIT.
Press: 10 # Input #
Input=0 for Door Sense; =1 for Inhibit
When programmed for DOOR SENSE, if an open condition on the input occurs
before access is granted (with an entry code or with the request-to-enter
input) a FORCED ENTRY output will occur. If an open condition remains beyond
the door ajar time following a valid relay activation for access, a DOOR AJAR
the output will occur.
When programmed for INHIBIT, a closed condition on the input will prevent Relay #1 from activating when access is requested with an entry code. This mode is typically used with an external timer to disable the access device at certain times.
