Magnetic contacts for intruder alarm systems: How they work and costs

Intruder alarm systems are an essential part of security technology in residential and commercial premises. Magnetic contacts are an important component of these systems. In this article, we will explain the functionality and costs of magnetic contacts for intruder alarm systems.

What is a magnetic contact?

A magnetic contact is a simple but effective mechanism used in intruder alarm systems. It consists of two parts: a reed switch and a magnet. The reed switch is a small, sensitive electrical component that is actuated by a magnetic field. The magnet is usually housed in a separate casing and is placed near the reed switch.

How a magnetic contact works

The way a magnetic contact works is quite simple. If the magnet is close enough to the reed switch, the switch is closed and the current can flow. If the magnet is removed, the switch opens and the current flow is interrupted. In an intruder alarm system, this interruption is triggered as an alarm.

A typical application example for a magnetic contact is the monitoring of doors and windows. The magnet is attached to the moving door or window sash, the reed switch to the fixed frame. If the door or window is opened, the magnet moves away from the reed switch, the circuit is interrupted and the alarm is triggered.

Costs of magnetic contacts

The cost of magnetic contacts can vary depending on the model and manufacturer. Simple models are available for just a few euros, while higher-quality models with additional functions such as vandalism protection can cost more. On average, however, you can expect to pay between 10 and 50 euros per magnetic contact.

Advantages of magnetic contacts

• They are easy to install and maintain.

• They are inexpensive and offer good value for money.

• They are reliable and have a long service life.

• They can be used in almost any environment, from apartments and houses to stores and offices.

Disadvantages of magnetic contacts

• You can only monitor doors and windows that can be opened and closed.

• They can be disturbed by strong magnetic fields.

• They offer no protection against glass breakage.

Magnetic contacts are an effective and inexpensive way of monitoring doors and windows in an intruder alarm system. They are easy to install and maintain and offer a high degree of reliability. Despite some disadvantages, they are an indispensable part of any intruder alarm system.

Magnetic contact intruder alarm system: How it works and costs in detail

The way a magnetic contact works is simple but effective. By monitoring the flow of current, they can reliably detect whether a door or window has been opened. The cost of magnetic contacts is relatively low compared to other components of an intruder alarm system, making them a cost-effective solution for building security. Despite some limitations, they are an important part of any intruder alarm system and contribute significantly to the security of residential and commercial premises.
