What Are The Various Types Of Door Alarms?

Door alarm types can be split in two categories, depending on the event or the technology that activates the alarm. The basic types of door alarms are door-open alarms and door-forced-open alarms.

Door-open Alarms

Door-open alarms activate when a door is opened by an intruder and held open for a certain period of time. The door-held-open time is programmable and used to monitor if a door is opened by an authorized access requestor. The door alarm warns the owner by emitting a chime, a loud siren sound or a flashing light, or both.

Door-open alarms are also called door-left-open alarms or door-held-open alarms. Door alarms of this type are made of two components: a magnetic stripe fixed on the door panel and an input sensor fixed at the door frame. When the contact between the magnet and the sensor is interrupted, the door alarm generates the warning signal.

Door-forced-open Alarm

Door-forced-open alarms activate when a door is opened by force, activating the switch contact.

An example of forced behavior is trying to get through a door without using a valid access card. Instead, the intruder uses physical force to get the door open.

‍‍Wireless door alarms are easily integrated into smart homes

All types of door alarms can be used for combination in comprehensive door alarm systems. These are usually powered up by wireless Internet and battery supplies to keep the whole building safe. Wireless door alarms use a Wi-Fi network to connect, integrate and monitor various access point in your home from a central control panel. They can be integrated into the already existing WiFi network or use an independent sim card to notify the user. They combine well with other types of alarms, such as motion detection and voice activation.

How Do They Serve Your Security Needs?

Door alarms serve to create safe homes and offices by warning against intrusion at access points that get opened often. They can work equally well with doors, windows and cabinets.

A door-held-open alarm with a pleasant chime can warn a receptionist that a visitor has just entered the building, leaving enough room for attending other duties. When an employee tries to forcefully break through an office door which he or she is not authorized to use, the monitoring system will let the controller know. Door-left-open alarms enable setting longer delivery times for goods, and reducing them when the delivery is complete. They guard against one of the most common security intrusion events - piggybacking or tailgating.

‍‍Keeping the whole family safe with one system

Door alarms are effective burglary protectors. At the moment a door is opened by a burglary attempt, the sensors can activate a flashlight, a loud siren and a phone call, or any combination of the above. The phone call system can be connected to the owner’s phone, to a private security contractor or to a law enforcement agency.

For home purposes, they can be used for energy saving, or for preventing cooking smells or smoke getting out of the kitchen. Door alarms can be used for children protection. By installing them on removable bed frames for toddlers, on dangerous home appliances or high-risk lockers or rooms, such as those storing chemicals or medicines, you can prevent your kids get into unwanted dangers.
