How to wire up electric strike alarms

An electric strike is an access control device designed to lock and release doors automatically. You’ll typically find them in or on door or window frames, preventing intruders or unauthorised people from entering through the passageway—and, if an alarm is attached, alerting you to potential intrusions.

A keyless lock is not a viable fit for every business, but an electric strike lock is a great option if you need extra security or want to prevent access to high-risk areas. These effective devices have evolved, gradually becoming one of the most efficient home and business security options.

Installing electric strikes is critical for workplace safety and effective access control—but it’s important to know how to wire it up properly. In this article, you’ll find out how electric strike systems work and how to install them safely and securely.

How electric strikes work

Electric strike locks are common in apartments, units, offices, commercial shops, and industrial workplaces. They help increase security while improving accessibility. These innovative locking systems work similarly to a normal deadbolt lock, except that they can be triggered remotely using an electric circuit on a separate circuit box.

But what’s the actual working function behind an electric strike lock?

Well, they work thanks to a spring-loaded bolt that an electric current can trigger. There are two main configurations that you can choose between—PTL (Power to Lock) And PTR (Power to Release).

As you might expect, with the PTL setting in place, applying power to your strike will automatically lock the device. Under PTR conditions, the device will unlock when you apply power.

Many electric strike devices have extra helpful features, including:

– Lock status sensors (LSS) that monitor the lock status of a door or window,

– Anti-tamper monitoring (ATM), to detect unauthorised persons attempting to remove the lock,

– Door status sensors (DSS) to monitor a door or window’s mechanical lock status.

Step-by-step guide to wiring your alarm

You can wire your electric strike locks independently, although hiring a professional is a smart choice if you don’t have experience with electrical wiring systems or if you don’t feel 100% confident in doing it yourself.

Installing an electric strike lock is a simple process, but the steps may vary depending on the manufacturer.

Step 1: Remove the old lock if you currently have one installed.

Step 2: Disconnect the wires from the old lock, including any wiring that someone else has already disconnected.

Step 3: Locate and mark the wires of your new electric strike lock.

Step 4: Connect the wires of your new electric strike lock to where they belong, including any wiring that someone else has already connected.

Step 5: Connect the battery of your new electric strike lock according to the manufacturer’s instructions if necessary.

Step 6: Test the connection and ensure it works properly before installing it on doors.


Installing an electric strike alarm is essential for businesses hoping to maintain control over access to private or high-risk areas. With the tips in this article in mind, you should have no trouble installing your new electric strike safely and securely.
