Why do the batteries in my Alarm Lock Trilogy lock drain faster than expected?

Batteries that tend to drain quickly are often the result of either a simple mechanical issue or a programming oversight. 

Mechanical

• Check for wiring issues such as frayed wires that are shorted under the mounting bracket or broken strands of wire at the connecter pins.
• Check for corrosion inside the battery pack or on the battery holder terminals.  Corrosion can cause resistive shorts.

Programming

• Many lock models are equipped with an internal relay, and it is possible this relay may have been previously programmed to energize upon a lock event.  Energizing the internal relay repeatedly or for extended periods will quickly drain the batteries, therefore locks that are programmed to energize the relay should be wired with external DC power.  Otherwise, you may wish to consider reevaluating the use of features responsible for the relay activation, and if needed, disable all relay functions using either DL-Windows software or through the lock keypad (see the printed programming instructions for details).  Always observe all warnings detailed in the programming instructions for these relay features before programming your lock.

Can’t find anything about energizing the internal relay or how to turn it off nothing in the manual about it. We are having to change the batteries every two weeks. Worked fine when we first installed the lock. Worked for several months. We have the DL2800.

If the lock is less than 2 years old, contact your installer or where you purchased the lock and have then get a replacement under warranty. 2 weeks is a different problem than the relay energizing.
