Simple to Install  -The DoorGard 212LS Lockset instal s in 15 minutes 
and 

programs the same as all DoorGard/IEI keypads. It includes 

all mounting hardware, and easily retrofits into any standard cylindrical 
door prep (ANSI/BHMA A 156.2-2003).  The 212LS has a replaceable 
core, for the manual key override.  The sleek design fits with any décor 
and is available in 26D Stainless and US3 Polished Brass, right or left 
handed crescent door handles.

Easy to Maintain -Change the battery in three minutes. The 212LS 
Lockset uses four (4) 1.5V AA batteries for up to 15,000 uses or up to 
five years. An alarm activates Low Battery Alert al owing for 30 more 
uses. 
User 

Codes - The 212LS lock recognizes up to 120 users with a 

different code for each, and the lockset retains codes without batteries.   
Codes can be one to six digits in length and digits can be repeated.  
The Master Code is always stored in user location one (1). A reset 
button is provided inside the lock which restores factory defaults and 
removes codes already stored. The lockset is equipped with an override 
mechanical key. The code toggles to al ow passage for an event so any 
key will open the lock.  
Security 

and Protection -The 212LS Lockset is designed with a  

safeguard against forced entry since the outside lever is not 
mechanical y connected to the latch until the lock activates.  Also, after 
three invalid code attempts, there is a 20 second lockout period for the 
keypad.   
Rugged 

Design -The 212LS  is designed for both commercial and 

industrial use.
