The more actively the detector is used, the higher the indicator. Limit number of operations It depends on the frequency of opening the window or door installed on the opening sensor. Signal transmission radius The signal transmission radius from the opening sensor for signalling to the security unit can be 80 m to 500 m. This may affect the correct operation of the window opening sensor for the alarm. Users need to consider that in summer, the frame can heat up to 50 ☌ or more. For example, the window opening sensors are installed on a south-facing window. When choosing a door sensor for an indoor facility, its temperature range must be considered. They are protected from the external environment. Reed switches in a metal case are suitable for outdoor installation on gates. By place of installation There are opening sensors for indoor installation and outdoor. Wireless opening detectors report tampering via radio connection and do not require wires. Wired devices are connected to the security system's control panel or GSM alarm system using two cables. By connection type Window and door opening sensors for alarms can be wired or wireless. And the likelihood of catching an intruder is higher if the alarm goes off immediately. By response time The sensors for opening doors and windows contain the response speed of the device. It must be taken into account before installing the opening sensor. Each reed switch has a minimum and maximum operating temperature limit for uninterrupted operation. Metal heats up and cools down more than plastic or wood, so an improperly selected reed switch may stop working due to the temperature. A metal surface reacts to a magnet, like a reed switch, so for metal objects - doors, gates, it is important to choose the appropriate detectors. Opening sensors by type of mounting surface Window or door opening detectors are installed on plastic, wood or metal. Opening detectors of this type are exposed to external influences and are noticeable in the interior this is a disadvantage for security devices. Overhead reed switches are attached using self-tapping screws or double-sided tape and are easy to install. A sensor with this type of installation is almost invisible in the interior. Installing a mortise reed switch requires special tools and takes time. Opening sensors by installation method Door opening sensors can be mortised or overhead. How to choose a door open sensor for alarm Before choosing an opening sensor, users need to familiarize themselves with its types and operating parameters. A magnetic field is created in the flask, which causes the plates' interaction and the sensor's operation.Two plates of nickel and steel are placed in a sealed glass flask.The principle of operation of the reed switch is as follows: A reed switch is a sealed switch that operates based on ferromagnetic spring contacts. Such sensors determine the opening of doors, hatches, windows and other elements. Wireless opening sensor Ajax DoorProtect Reed switches or sensors for opening doors and windows are used to protect the premises from intrusion.
