With vhfBridge you can use Ajax systems in cities where Internet connection is unstable, in nature reserves, mountain and desert areas\u003c\/li\u003e\n\t\u003cli\u003eAlarms and events of the system are transmitted via VHF radio waves over tens of kilometres1. vhfBridge can be used as a primary or a backup communication channel\u003c\/li\u003e\n\t\u003cli\u003eYou can build in a 7 Ah backup battery inside a vhfBridge casing. It will feed a VHF transmitter with up to 2A current consumption. Therefore, the transmitter doesn't need to have a separate battery, which makes maintenance less frequent\u003c\/li\u003e\n\t\u003cli\u003eIn case of a power outage at a facility, the transponder and the transmitter operate on a backup battery for up to 75 hours4 while still transmitting events to a central monitoring station\u003c\/li\u003e\n\t\u003cli\u003eSimilar to other Ajax devices, vhfBridge connects to a hub in the app by scanning a QR-code. The transponder casing has perforated areas for more organized wiring. Outputs are configurable with Ajax apps for smartphones and computers\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCompatible with Ajax central units : Hub 2, Hub Plus, Hub 2 Plus\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTech specs\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eClassification : Transponder for communication with the monitoring station via a VHF transmitter\u003c\/li\u003e\n\t\u003cli\u003eInstallation : Indoors\u003c\/li\u003e\n\t\u003cli\u003eNumber of potential outputs : 8\u003c\/li\u003e\n\t\u003cli\u003eOutput types : Positive trip and negative trip (depends on the settings)\u003c\/li\u003e\n\t\u003cli\u003eTransmission types : Pulse and bistable (depends on the settings)\u003c\/li\u003e\n\t\u003cli\u003eRecommended VHF transmitters : Hawk VHF Alarm Transmitter from FSK Electronics \/ TX750C from RDC \/ TR-41 from Puper\u003c\/li\u003e\n\t\u003cli\u003eCompatible with Ajax range extenders : +\u003c\/li\u003e\n\t\u003cli\u003eCompatibility with third-party VHF radio transmitters : vhfBridge connects to any VHF transmitter with relay inputs\u003c\/li\u003e\n\t\u003cli\u003eSupport for photo verification of alarms : No\u003c\/li\u003e\n\t\u003cli\u003ePrimary power supply : 100–240 V, 50\/60 Hz\u003c\/li\u003e\n\t\u003cli\u003eBackup power supply : 12 V DC, up to 75 hours of power for a transponder and a transmitter\u003c\/li\u003e\n\t\u003cli\u003eSupported battery type : 12 V battery with a full charge cycle of up to 30 hours. \/ The maximum battery size installed in the casing should be 150 × 64 × 94 mm\u003c\/li\u003e\n\t\u003cli\u003eRecommended battery type : 12 V battery with a capacity of 4 Ah or 7 Ah \/ Backup battery is not included in the set\u003c\/li\u003e\n\t\u003cli\u003eVHF transmitter power : 12 V DC, 2 A\u003c\/li\u003e\n\t\u003cli\u003eAnti-sabotage : Protecting against forgery \/ Jamming notifications \/ Tampers against opening and removal \/ Backup battery\u003c\/li\u003e\n\t\u003cli\u003eJeweller radio protocol : Communication range — up to 1,800 meters in a line of sight \/ Two-sided communication between devices \/ Operating frequencies: 868.0–868.6 MHz \/ Auto-regulated radio signal power: ≤ 25 mW \/ Blocking encryption based on the AES algorithm \/ Detector ping interval: 12–300 seconds \/ Frequency hopping\u003c\/li\u003e\n\t\u003cli\u003eMaximum radio signal power : ≤ 25 mW\u003c\/li\u003e\n\t\u003cli\u003eProtection class : IP50\u003c\/li\u003e\n\t\u003cli\u003eOperating temperature range : From –10°C to +40°C\u003c\/li\u003e\n\t\u003cli\u003eOperating humidity : Up to 75%\u003c\/li\u003e\n\t\u003cli\u003eOverall dimensions : 196 × 238 × 100 mm (with casing) \/ 145 × 89 × 51 mm (without casing)\u003c\/li\u003e\n\t\u003cli\u003eWeight : 840 g (with casing) \/ 165 g (without casing)\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Ajax","offers":[{"title":"Default Title","offer_id":59998679859584,"sku":"22805","price":153.3,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0613\/0571\/6788\/files\/VHFTransmitter.jpg?v=1790686407","url":"https:\/\/atlantic-mall.com\/de\/products\/ms-electronics-15136","provider":"Atlantic Shopping Mall","version":"1.0","type":"link"}
