THE ALARM LOCK TRILOGY DL-SERIES STAND-ALONE ACCESS CONTROL SYSTEM IS A SERIES OF STATE-OF-
THE-ART MICROPROCESSOR-BASED PROGRAMMABLE KEYPAD-ENTRY SECURITY LOCKS. 
DL3500, DL3500EX, DL3200 & ETDL 
Features a real-time clock/calendar that automatically adjusts for Daylight Sav-
ing Time and allows for automated programming of events. Features three 
methods of programming: (1) all features can be programmed manually through 
the keypad; (2) you can transfer programming instructions directly from your lap-
top or desktop PC using DL Windows software and a special AL-PCI cable; and 
(3) data can be transferred from your PC to your DL lock via the AL DTM hand-
held Data Transfer Module. In addition, data can be retrieved from the lock in 
one of three ways (1) through an infrared printer; (2) directly from the lock to the 
PC; or (3) through an AL-DTM to your PC. 
The DL Series locks include several lock types: a lock for the European market 
(DL3500EX), a mortise-based lock for additional hardware security (DL3500), 
and a mortise-based lock for use with push bar applications (ETDL). 
Programming is identical for all locks.
