Das zweite Leben einer alten kabelgebundenen Alarmanlage
Häufig kommt es vor, dass ein kabelgebundenes Alarmsystem Ihr Eigentum zwar noch schützen kann, aber bereits eindeutig überholt ist. Eine Modernisierung mit Ajax zwingt Sie nicht, Ihr aktuelle Ausrüstung aufzugeben. Sie haben vielmehr die Möglichkeit, ein modernes komplexes Sicherheitssystem aufzubauen, das auf Ihrer vorhandenen Draht-Alarmanlage basiert.
AJAX MultiTransmitter ist ein Integrationsmodul mit 18 Anschlussmöglichkeiten für Melder von Drittanbietern an das Ajax Sicherheitssystem. Zum Schutz gegen Sabotage und Demontage ist der MultiTransmitter mit zwei Manipulationsschutzvorrichtungen ausgestattet. Er wird mit 100 V bis 240 V Wechselstrom aus dem Netz gespeist und kann auch mit einem 12 V Notstrom-Akku betrieben werden. Zudem versorgt er die angeschlossenen Melder mit 12 V.
Der MultiTransmitter arbeitet als Teil des Ajax Sicherheitssystems und ist über das sichere Funkkommunikationsprotokoll "Jeweller" mit der Hub-Zentrale verbunden. Die Übertragungsreichweite der Hub-Zentrale beträgt bis zu 2000 Meter (Freifeld). Bei festgestellten Störungen (Jamming) oder Interferenzen wird das Ereignis „Hohe Störsignale im Rahmen der Jeweller Frequenzen“ an die Überwachungszentrale des Sicherheitsdienstes und die Systembenutzer übermittelt.
Das Gerät verbindet sich mit dem Hub und wird über Ajax Apps auf iOS, Android, MacOS und Windows konfiguriert. Alle Alarme und Benutzerereignisse werden durch Push-Benachrichtigungen, SMS und Anrufe gemeldet, falls aktiviert. Das Ajax Sicherheitssystem kann mit der Überwachungszentrale des Sicherheitsdienstes verbunden werden.
Hinweis: Der Transmitter ist nicht kompatibel mit ocBridge Plus, uartBridge und Sicherheitszentraleinheiten von Drittanbietern.

Amazing detail and story
Format: Hardcover
We visited Chartwell in June 2023. I sure wish I had read this book prior to that visit. I was still able to scroll through my photographs and compare them with the book photos or comments.
All in all the book is excellent. It manages to complete the story of Churchill in Exile and give the reader a glimpse of all the work he accomplished leading up to WWII. It also begs the question if given a leadership role earlier Churchill could have prevented the war in the first place. As someone who lost his uncle over France in 1943 that would have been nice. I highly recommend this book. A great man.

10/10 recommend
Format: Hardcover
Great book, especially if you're a fan on WWII or Winston Churchill! I never really dove into Churchill specifically before this book, but I was very impressed with how much influence he had leading up to the war, even when he wasn't a political official. It's also wild to think about how different things could have been if people took his warnings sooner. Overall I love the book and I think it's a very interesting read even if you're not that into history!

Churchill's "wilderness years" at Chartwell were perhaps the "important years" in preparing him.
Format: Hardcover
A brilliant idea for a new perspective on Churchill, and an even better execution. The author literally examines the guestbook over a ten-year period at Chartwell, Churchill's country home. Not only are the names of the guests fascinating, but the subjects of their discussions are eyebrow-raising in multitudes of ways. From Einstein to German spies, from politicians to celebrities, Churchill was not only busy maintaining connections he deemed useful, but his efforts to stay well-informed were Herculean.
He did not hold an elected office during these "wilderness years," but he dictated volumes of books (no doubt improving his oratory skill), built brick walls, gardened, painted, and traveled like his life depended on it. It is fascinating to gain these new insights into the man. Depressed by his recent failure to be re-elected, he went to work instead of retiring. He imposed upon himself a strict diet of information protein, personal network building, philosophical expansion, and extraordinary production.
All the visitors, discussions, and interactions ultimately resulted in the most fantastic preparation imaginable for a man destined to lead his country as Prime Minister during the greatest war the world has ever known. I found the book extremely well-written yet easy to read, finishing it in just two days.

Excellent pre WW2 Churchill primer.
Format: Hardcover
This author has done an excellent job of explaining the role Churchill played in preparing Britain for WW2 despite being out of government for most of the 1930’s. The author is a curator and historian who has managed the collections at Chartwell, Churchill’s home during that time. Very well researched and easy to read. Anyone who studies 20th Century European history needs to read this book.

Book for Churchill fans
Format: Hardcover
Not an introduction to Churchill but fills out a period of his life that is often overlooked. Some fascinating insights into people who visited Chartwell. I really enjoyed this book, but it's not for everyone.
