The 923 Indoor/Outdoor Keypad Surface Mount 

EntryCheck

™ is a digital 

keyless entry system designed for access control applications. The  
keypad is integrated in a heavy cast vandal resistant housing, designed to 
be mounted on a  rugged, surface mounting plate and may be mounted in 
a standard single-gang electrical box.  The indoor/outdoor backlit keys  
have bright, easy-to-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 “anti-passback” 
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 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 923 

EntryCheck

™ is powered from a 12 or 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.
