No home is safe from burglaries, whether at home or on vacation. In addition to the usual precautions, the opening detectors will reinforce the security of doors and windows. Here is a practical guide to know everything about this type of alarm system.

Opening detector: what is it?

The opening detector or magnetic opening detector is a key component of the alarm rf wireless system. To be functional and to be able to detect an undesirable presence when it is activated, it must include several elements such as alarm sirens, a remote control, detectors of all kinds and an alarm central. The purpose of the opening detector is to detect an offensive intrusion or the opening of the various accesses of a dwelling, a business or a professional premise. These detectors can be placed on doors, windows, shutters or access to ventilation ducts.

What are the components of a peripheral detector?

Also called a peripheral detector, the magnetic opening detector has two complementary components. The first is a fixed electronic element that supports the flexible switch that is installed on the door jamb. The second is mobile and has a built-in magnet that attaches to the door or window. Generally, this safety device does not require the installation of electrical wires. It is powered by batteries that are delivered with purchase. Depending on the models offered, accessories such as screws or adhesive tapes to fix the elements are included in the pack.

How does the peripheral sensor work?

The peripheral sensor is operated by a magnetic system. The alarm is triggered automatically when the two parts of the device are separated. If the door or window is opened by more than 5 mm, the detector detects a change of state and immediately sends a signal to the central alarm unit. The latter records this change and reacts either by emitting an audible alarm signal or by sending the intrusion information to a remote monitoring operator.

The advantages of a magnetic opening detector

This security feature has several advantages. Its main role is to prevent the intrusion of a burglar or an intruder through the various openings of a dwelling. It can be used anywhere: in a shop, a pharmacy, a company, etc.. As soon as a door or remote control blinds, the siren that sounds is enough to deter and scare away intruders in 9 out of 10 cases. In addition to access to a home, this type of sensor also protects a drawer, a chest of drawers or a cupboard containing valuable objects.

How to install this type of sensor?

The peripheral sensor is installed in two steps. In a first one it is necessary to install the wireless part that includes the fixed electronic element that serves as a long range video transmitter. It is placed on the upright or frame of the door or window using adhesive tape or screws. Then install the magnetic part that is fixed on the mobile part of the access. During this step, a maximum distance of 5 mm must be maintained between the two parts. It must also be ensured that there is sufficient distance between the device and the hinges to facilitate opening. The ideal is to choose a small size model that is both discreet and functional.
