How does Residential Alarm Work 

Here you will get a description about how does residential alarm work and most important facts about boligalarm.

Door and Window Contacts

These are switches. They can indicate the opening and closing of a door or window. You need to mount the switch to a door or window. There it will be held closed by a magnet attached to the frame. The switch opens if the door or window moves from the magnet. Then, it is sensed by the alarm control panel.

Motion Sensors 

Motion sensors are especially applicable for large rooms. They can detect motion or movement in a large room.

Glass Break Detectors

These detectors listen constantly for the sound of breaking glass. The instant such detector hears the sound pattern caused by shattering glass, an electrical signal is sent to the alarm control panel.

Shock Sensors 

If an intruder uses force to pound through a roof, or wall, shock detectors can detect that.

Carbon Monoxide (CO) Detectors

Carbon monoxide is an odorless, invisible, and colorless gas. These detectors can detect this gas. If it detects CO, a signal will be sent to the control panel by the sensor. Then, the control panel will emit an audible alarm.

Panic Buttons

You just need to press a button. Then, it will send an immediate and discreet call for help.


Environmental Senors

These sensors can detect changes in environment. They can react to the presence of water. They will also react to sudden increases or decreases in room temperature.

Smoke Detectors

These detect fire. They are of two types: photoelectric and ionization.  Photoelectric detector can detect smoldering fires producing large amounts of smoke. Ionization detector can react to flaming fires, which do not have a lot of smoke. A smoke detector that combines both forms of detection is considered as the most effective.


A keypad can arm and disarm an alarm system. These are usually installed at the entrance or exit of a home. If someone opens a door or window when the system is activated, the system will immediately start an alarm.


The Control Panel

This is the brain of the whole alarm system. It processes the information it receives from different sensors. Then, it responds accordingly.

It has built in communicators. These transmit and receive signals through a phone line. Then, these signals are sent to a central alarm monitoring system. If an alarm is triggered, a dispatcher will contact you to verify the situation. They will also notify the police or fire service, if necessary.

This article about residential alarms should give you a clear understanding of the system. Now, you can choose an alarm system based on your needs and preferences.
