INSTALLATION INSTRUCTIONS
918 ENTRY CHECK®

The 918 EntryCheck™ is a digital keyless entry system designed for
access control applications. The keypad is mounted on a rugged,
stainless steel faceplate and is designed to be mounted in a standard
single-gang electrical box. The indoor backlit keys have bright, easyto-read graphics.
Up to 500 entry codes, from 1 to 6 digits in length, can be programmed.
They can activate either, or both of the relay outputs. The “antipassback” feature prevents using the same code again before the
programmed time elapses.
All system indicators are long-lasting, solid state LEDs. Two indicators
show the status of the entry system. The left indicator lights red to
indicate power, then turns green when access is granted. The right
indicator lights yellow when the keypad is in “lockout” condition (from
too many incorrect code entries). The yellow LED flashes when the
keypad is in programming mode. An internal sounder beeps when each
key is pressed. An internal jumper sets the sounder volume high or low
The SENSE input can be used two ways. If programmed for “door
sense” the input is wired to a normally closed switch on the door to
detect when the door is opened or closed. Forced entry or door ajar
situations can then be detected. Using door sense, the “Auto-relock”
feature will prevent “tailgating” by turning off the Main Relay output
immediately when the door is closed after access has been granted. If
the SENSE input is programmed for “inhibit”, the input can be wired to a
“service” switch or automatic timer that will disable the Main Relay when
required.
The REQUEST-TO-EXIT input can be wired to a pushbutton to provide
codeless activation of Main Relay, Auxiliary Relay, Output #3 or Output
#4 (programmable).
The ALARM SHUNT output activates when access is granted. This
output can be wired to shunt alarm contacts on the access door/gate to
prevent triggering of an alarm when authorized access occurs.
The 918 EntryCheck™ is powered from a 12-24V AC or DC source.
The EEPROM memory retains all entry codes and programming, even
without power. 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 switching 100 mA to
common, are programmable to signal forced entry, door ajar, lockout,
alarm circuit shunting, request-to-exit, and keypad active conditions.

QuickStart Programming
To enter Programming Mode, enter #9# plus the Master Code. The yellow indicator will blink slowly showing that the 918 EntryCheck™
is in programming mode. Use the option codes to program the each function. After the new data entry is complete for each function , the
yellow indicator will flash quickly while the data is being stored and the green indicator will light briefly if the programming has been
accepted. The red indicator will light if any programming data is entered incorrectly or the function is rejected. If a red indicator is seen,
the entire function (option code + data) will have to be fully re-entered.

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. A magnetic 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: Up to 500 feet of 18 AWG wire can be run for power, use larger wire
for longer runs. Use 22 AWG or larger (depending on load) for other
connections.

Output
Install a low voltage electric door strike for unlocking the door.
Route two wires between the door strike and the keypad box.
Connect the (+) door strike wire to the keypad’s MAIN RELAY N.O.
terminal (TB1 #3). Connect the other door strike wire to the keypad’s
AC/DC (-) terminal (TB1 #2). Connect a wire between the keypad’s
AC/DC (+) terminal (TB1 #1) and the MAIN RELAY COM terminal
(TB1 #4).

To use the door sense feature to 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 box. Connect the door switch
to the keypad’s SENSE terminal (gray wire E8) and COM terminal
(any black wire).
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 box. Connect the inhibit switch/timer normally open terminals
to the keypad’s SENSE (gray wire E8) and COM (black wires)
terminal.

BASIC PROGRAMMING
When the 918 EntryCheck™ is in Programming Mode, both
indicators will turn off until programming begins. After a
programming option number is entered, the yellow indicator will
blink. This shows that the 918 is ready to accept the new
programming data. After the new data entry is complete, the
yellow indicator will flash while the data is being stored. The
green indicator will light if the data is accepted. The red indicator
will light if any programming data is entered incorrectly, and the
command will have to be fully re-entered.

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 yellow indicator will flash quickly while the 918 searches its
memory for available space and duplicate entries. The green
indicator will light when the new code is stored.
If the new entry code chosen is already being used for another entry
code, the red indicator will light. A new unique code needs to be
entered.
Note: Leading zeros (zeros before the code number, i.e.0001) do not need to
be entered when programming a new code. The 918 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.

Erasing a Single Entry Code
Press: 0 2 # Code # Code #
Code=The entry code to delete
The yellow indicator will flash quickly while the 918 searches its
memory for the code to erase. The green indicator will light when
the code is erased.

SDC’s EntryCheck™ products have a programmable “Toggle
Mode” available for each relay and solid-state output. When an
output is programmed for Toggle Mode, the output alternates from
OFF to ON or from ON to OFF each time it is activated. When
output is toggled on, the green LED flashes until toggled off.
The rules for a toggle output are:
If the output is OFF, it will turn ON and stay on until the next
activation.
If the output is ON, it will turn OFF and stay off until the next
activation.

(Typical Programming cont.)

Program all normal entry codes to use the Main Relay (Relay
#1), and only Relay #1 as the output relay. Program the code(s)
that you want to use to hold the output for an indefinite period to
the Auxiliary Relay (Relay #2). See the following example that
sets entry codes 1234 for normal and 5678 for toggle operation.
Press: 0 1 # 1 2 3 4 # 1 2 3 4 # 1 #
01=Programming Step; 1234=Entry Code; 1=Main Relay
Press: 0 1 # 5 6 7 8 # 5 6 7 8 # 20 #
01=Programming Step; 5678=Entry Code; 20=Auxiliary Relay
Toggle
Typical Toggle Mode Wiring
For devices triggered by a normally open circuit, wire the
contacts of the Main and Auxiliary Relays in parallel (see the
Figure below). Either relay will be able to trigger the access
device. Entry codes programmed for the Auxiliary Relay will be
able to hold the output on.

RESETTING KEYPAD
Master Reset
CAUTION: Performing a master reset will clear the
entire memory of the 918 and return all programmable
options to the factory default values. ALL ENTRY
CODES WILL BE ERASED.
STEP 1 Disconnect power from the keypad.
STEP 2 Press and hold down the * and # keys.
STEP 3 Apply power to the keypad, continue holding the keys
down until the red indicator starts flashing
STEP 4 Release the keys. The red and yellow indicators will
remain lit until the process is complete, then the
yellow indicator will go out.
Resetting the Master Code
STEP 1 Remove the 918 from the wall..
STEP 2 Locate jumper at JP2. This jumper is used to reset
the master code.
STEP 3 With power applied to the keypad, remove the jumper
at JP2. The keypad will begin to beep, signaling that
the code has been reset.
STEP 4 Replace jumper on JP2
THE MASTER PROGRAMMING CODE IS NOW 123456.
Beeper Sound Level
The Keypad’s beeper can be set to high or low level.
Remove jumper JP1 to reduce beeper sound level.
