An electric door strike is an electro mechanism that locks or unlocks an entrance door from a distance when supplied with voltage.
Electric strikes have expanded over time due to an increase in criminal acts. Most apartment buildings have different types of electric strikes to keep the safety of residents.
Two types of electric strikes are on the market today; fail-secure electric strikes, non-electrical power keep the entrance door locked, and a fail-safe that requires an electrical power supply to block the door entrance.
There are electric strikes that use different voltages, and the most popular is the 8-16 V AC electric strikes, although other models, which work with direct voltage, emit no noise when running. Among the most popular models, we find 12-24 V DC electric strikes.
Electric strikes are for flush installation, but there are also electric strikes for surface mount and semi-flush installation, such as in the emergency exit doors that use these electric strikes models.
Electric strikes usually are connected to; intercom systems, video intercom systems, fire alarm systems, which will make them work remotely.

Or by programming the access control, which will activate the electric strike and give access at different times or days of the week.
