What are magnetic detectors?

Contactrons, or magnetic detectors, are the basic elements of peripheral security in alarm systems. They consist of two parts: a magnet and a sensor (reed–switch). When the magnet is removed (e.g. the door or window is open), the sensor contacts disconnect and the alarm is generated. {index=0}

Why is it worth using ektrona?

• Simple and reliable detection: Magnetic detectors are very durable, almost not mechanical.
• Circuit protection: Ideal for protecting windows, doors, gates or gates – they react to the opening of the wing. {index=1}
• Flexible assembly: Surface versions (mounted on the frame) as well as mounted (hidden in the frame) are available. {index=2}
• Security of sabotage: Models such as Satellite S–4 have a tamper contact that detects the opening of the housing. {index=3}

What should I pay attention to when choosing contactron?

• Installation type: Choose between the surface version and the window/door frame. {index=4}
• Contact parameters: Check if the detector has EOL resistors (e.g. 2EOL) – important for integration with the control panel. {index=5}
• Operating distance: Magnets and contactrons should be close enough to provide some detection. {index=6}
• Safety standards: It is worth choosing models compatible with EN 50131 (e.g. Grade 2). {index=7}
• Durability: Check how many work cycles the manufacturer declares – good contacts can withstand many openings/closures. {index=8}

Most common questions (FAQ)

Does every contactron fit into my emergency room?

Not always — you need to check that your control unit supports NC inputs and (if needed) a tamper loop. S-4 and K-2 models offer such features. :contentReference[oaicite:17]{index=17}

How do I mount contact points on a window/door?

The magnet shall be mounted on a movable part (wing) and the detector on a fixed part (stair), within the range of operation of the magnet, as documented by the manufacturer. :contentReference[oaicite:18]{index=18}

Can the contactron be hidden in the window frame?

Yes, there are flush versions designed to be mounted inside the frame and left invisible after closing. :contentReference[oaicite:19]{index=19)
