Recently, we have decided to film a series of videos and write a series of articles, dedicated specifically to Ajax Systems. The goal is to write about and to film every single device out of all 25 approximately that Ajax Systems has at the moment.
And thus, we continue with the Ajax DoorProtect and Ajax DoorProtect Plus – you are going to learn the devices’ intended functionality, how to start the start-up devices, see a working principle, and also find out what distinctions do regular and plus versions have.
Working Principle
The device is quite simple in its working principle. But what they don’t say in the name – it’s also a window opening detector, used for doors and windows equally. And that is why we have an additional magnetic contact in the box besides the main sensor. That is just a tiny magnet, and that is why it perfectly fits for a Windows install. The same as a second magnet, made in the shape of the main sensor – but that’s just a magnet too, intended for installation on a door.
Now, this is the main and the only sensor in here, and well, you know, the working principle is based on a reed switch, which is able to detect when the contacts are closed or open due to a magnetic field principle.
The DoorProtect Plus box contents are one hundred percent identical to a regular version, except the sensor’s filling, because it has, in addition, the accelerometer, which enables the sensor be able to feel a tilt applied to it and also detect an impact applied to an adjoining door or a window. For now, that’s all the functional distinctions they have, but what we are curious about – how does that affect our interaction and working with the device?
Charachteristics & Distinctions
On the box back, we can see, the accelerometer in stock decreases the battery life from up to 7 years in regular to 5 years in the Plus version. But with the accelerometer on board, it opens the possibility to detect if the adjoining door or the window was harmed, and also it opens the possibility to arm the system with this sensor in a half-open position.
Meaning, if you have opened your window in the ventilation mode and the main sensor has a gap between a magnetic contact, you won’t get an alert that the sensor is open, because it is able to remember it’s position, and if something changes after that, if the window was harmed or tilted more than expected – you’ll get an instant intruder alert.
So yes, you hang it on a door or a window, arm the system, and if some intruder opens it, you’ll know that instantly, due to a reed switch working principle. The operational range of both sensors is 1,200 meters within a 12-second ping frequency, and you can also pair it with a wired NC detector.
Activation &Connection
We thought the best way was to show you, so here comes the video:
Conclusion
Simple, yet the most efficient kind of detector, that is based on a reed switch working principle, and wу also got here an option to install it on the window. Simple, modern, and futuristic design, black and white color body options, plus an Ajax user-friendly device ecosystem within a few Ajax-exclusive technologies, low price, and long battery life make it a perfect pick. And that is why Ajax Systems has such many awards.
